Family History of Psychiatric Disorders and Alcohol and Substance Misuse in Patients with Bipolar I Disorder, Substance Use Disorder, or Both

THE AMERICAN JOURNAL ON ADDICTIONS, Issue 3 2007
Alfredo Sbrana MD
Family history data were collected on first-degree relatives of 78 patients with bipolar I disorder (BD) and substance use disorder (SUD), 47 with BD only, and 35 with SUD only. The prevalence of psychiatric disorders was significantly higher in first-degree relatives of patients with BD + SUD (64%) and BD (61%) compared with first-degree relatives of SUD patients (20%). The prevalence of alcohol misuse was significantly higher in first-degree relatives of patients with BD + SUD (23.1%) and SUD alone (28.6%) compared to first-degree relatives of patients with BD (4.3%). Our findings suggest that BD and SUD do not share familial risk factors. [source]


Increased right amygdala volume in lithium-treated patients with bipolar I disorder

Usher J, Menzel P, Schneider-Axmann T, Kemmer C, Reith W, Falkai P, Gruber O, Scherk H. Increased right amygdala volume in lithium-treated patients with bipolar I disorder. Objective:, The amygdala plays a major role in processing emotional stimuli. Fourteen studies using structural magnetic resonance imaging (MRI) have examined the amygdala volume in paediatric and adult patients with bipolar disorder (BD) compared with healthy controls (HC) and reported inconsistent findings. Lithium has been found to increase grey matter volume, and first evidence points towards an effect on regional brain volume such as the amygdala. Method:, We examined the amygdala volume of euthymic patients with BD treated with lithium (n = 15), without lithium (n = 24) and HC (n = 41) using structural MRI. Results:, Patients treated with lithium exhibited in comparison to HC a larger right absolute (+17.9%, P = 0.015) and relative (+18%, P = 0.017) amygdala volume. There was no significant difference in amygdala volume between patients without lithium treatment and HC. Conclusion:, Lithium appears to have a sustained effect on a central core region of emotional processing and should therefore be considered in studies examining BD. [source]


Birth-cohort and dual diagnosis effects on age-at-onset in Brazilian patients with bipolar I disorder

ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2009
P. V. Da Silva Magalhães
Objective:, Substance use disorders and birth-cohort have been associated with an earlier onset in bipolar disorder (BD). This study aimed at evaluating the inter-relations of these factors in age-at-onset in bipolar illness. Method:, Two-hundred and thirty patients with bipolar I disorder were cross-sectionally evaluated. Patients were categorized into four age groups for analysis. Lifetime comorbidity and age-at-onset were derived from the Structured Clinical Interview for DSM-IV. Results:, There was a strong linear association between age group and age-at-onset. Lifetime alcohol and drug use disorders were also associated with age-at-onset. Illicit drug and alcohol use disorders and age group remained significant in the multivariate model. No interactions appeared. Conclusion:, Both age group and dual diagnoses had strong and independent impacts on age-at-onset in out-patients with BD. Substance abuse may be partly accountable for earlier symptom onset, but other features of BD in younger generations are still in need to be accounted for. [source]


Depressive relapse during lithium treatment associated with increased serum thyroid-stimulating hormone: results from two placebo-controlled bipolar I maintenance studies

ACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2009
M. A. Frye
Objective:, To assess the relationship between depressive relapse and change in thyroid function in an exploratory post hoc analysis from a controlled maintenance evaluation of bipolar I disorder. Method:, Mean thyroid-stimulating hormone (TSH) and outcome data were pooled from two 18-month, double-blind, placebo-controlled, maintenance studies of lamotrigine and lithium monotherapy. A post hoc analysis of 109 subjects (n = 55 lamotrigine, n = 32 lithium, n = 22 placebo) with serum TSH values at screening and either week 52 (±14 days) or study drop-out was conducted. Results:, Lithium-treated subjects who required an intervention for a depressive episode had a significantly higher adjusted mean TSH level (4.4 ,IU/ml) compared with lithium-treated subjects who did not require intervention for a depressive episode (2.4 ,IU/ml). Conclusion:, Lithium-related changes in thyroid function are clinically relevant and should be carefully monitored in the maintenance phase of bipolar disorder to maximize mood stability and minimize the risk of subsyndromal or syndromal depressive relapse.

Neurocognitive functions in euthymic bipolar patients

ACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2009
K. Jamrozinski
Objective:, Meta-analytic findings support the hypothesis of specific neurocognitive deficits for bipolar patients in the domains of attention, processing speed, memory and executive functions. This study aims to show neurocognitive impairment in euthymic patients with bipolar I disorder compared with healthy controls while detailing the impact of medication side-effects or illness characteristics on neuropsychological test performance. Method:, Forty euthymic patients with bipolar I disorder were compared with 40 healthy controls in a cross-sectional design. Clinical features and neuropsychological measures of IQ, psychomotor speed, verbal fluency, learning and memory, executive functions and attention were assessed. Results:, Patients without antipsychotic drug use did not differ significantly from healthy controls in any neuropsychological measure. Yet patients treated with antipsychotics showed significant underperformance in the domains of semantic fluency, verbal learning and recognition memory as well as executive functions related to planning abilities, even when clinical features were controlled for. Conclusion:, The impact of antipsychotic medication needs to be further clarified for euthymic bipolar patients and should be considered when neuropsychological test performance is interpreted.

Expressed Emotion Attitudes and Individual Psychopathology Among the Relatives of Bipolar Patients

FAMILY PROCESS, Issue 4 2002
Tina R. Goldstein M.A.
This study investigated the relationships between expressed emotion (EE) and individual psychopathology among 82 biological and non-biological relatives of 66 patients with bipolar I disorder. Relatives' psychopathology was assessed via the Structured Clinical Interview for DSM-III-R, Patient Version (SCID-P) and the General Behavior Inventory (GBI), a self-report measure of lifetime subsyndromal mood disturbances. We hypothesized that relatives who held high-EE critical, hostile, and/or overinvolved attitudes toward their bipolar family member, as measured via the Camberwell Family Interview, would be more likely to have DSM-III-R Axis I diagnoses on the SCID, as well as more mood and temperamental disturbances on the GBI, than those who held low-EE attitudes. The findings did not support a significant relationship between overall EE status and psychopathology in family members. However, relatives without significant Axis I pathology scored significantly higher than those with Axis I pathology on one measure of EE, emotional overinuolvement. The findings are discussed with reference to explanations for the genesis of high-EE attitudes. [source]


Hyperactivity, startle reactivity and cell-proliferation deficits are resistant to chronic lithium treatment in adult Nr2e1frc/frc mice

GENES, BRAIN AND BEHAVIOR, Issue 7 2010
B. K. Y. Wong
The NR2E1 region on Chromosome 6q21-22 has been repeatedly linked to bipolar disorder (BP) and NR2E1 has been associated with BP, and more specifically bipolar I disorder (BPI). In addition, patient sequencing has shown an enrichment of rare candidate-regulatory variants. Interestingly, mice carrying either spontaneous (Nr2e1frc) or targeted (Tlx,) deletions of Nr2e1 (here collectively known as Nr2e1 -null) show similar neurological and behavioral anomalies, including hypoplasia of the cerebrum, reduced neural stem cell proliferation, extreme aggression and deficits in fear conditioning; these are the traits that have been observed in some patients with BP. Thus, NR2E1 is a positional and functional candidate for a role in BP. However, no Nr2e1 -null mice have been fully evaluated for behaviors used to model BP in rodents or pharmacological responses to drugs effective in treating BP symptoms. In this study we examine Nr2e1frc/frc mice, homozygous for the spontaneous deletion, for abnormalities in activity, learning and information processing, and cell proliferation; these are the phenotypes that are either affected in patients with BP or commonly assessed in rodent models of BP. The effect of lithium, a drug used to treat BP, was also evaluated for its ability to attenuate Nr2e1frc/frc behavioral and neural stem cell-proliferation phenotypes. We show for the first time that Nr2e1 -null mice exhibit extreme hyperactivity in the open field as early as postnatal day 18 and in the home cage, deficits in open-field habituation and passive avoidance, and surprisingly, an absence of acoustic startle. We observed a reduction in neural stem/progenitor cell proliferation in Nr2e1frc/frc mice, similar to that seen in other Nr2e1 -null strains. These behavioral and cell-proliferation phenotypes were resistant to chronic-adult-lithium treatment. Thus, Nr2e1frc/frc mice exhibit behavioral traits used to model BP in rodents, but our results do not support Nr2e1frc/frc mice as pharmacological models for BP. [source]


Effect of risperidone on plasma catecholamine metabolites and brain-derived neurotrophic factor in patients with bipolar disorders

HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 7 2006
Reiji Yoshimura
Abstract A combination treatment with a mood stabilizer and an antipsychotic drug is often used in as many as 90% of subjects with acute mania. Recently, augmentation therapy with atypical antipsychotics has been investigated in both the acute and long-term treatment of bipolar disorder with or without psychosis. In the present study, the authors investigated the efficacy of risperidone treatment for both acute manic and depressive episodes in bipolar disorder. Eighteen patients (M/F: 8/10, age: 34,±,15,yr) who met the DSM-IV criteria for bipolar I disorder (12 cases of manic episodes, 6 cases of depressive episodes) with risperidone treatment were evaluated regarding their clinical improvement using the Young Mania rating Scale (YMRS) and the Hamilton rating Scale for Depression (Ham-D). Plasma concentrations of HVA and MHPG were analyzed by HPLC-ECD and plasma brain-derived neurotrophic factor (BDNF) levels were detected by sandwich ELISA. The mean scores of the YMRS were 22, 18, 12, 8, and 5 at time points before and 1, 2, 3, and 4 weeks after the risperidone administration, respectively. The mean scores of the Ham-D were 24, 25, 21, 21, and 19 at time points before and 1, 2, 3, and 4 weeks after the risperidone administration, respectively. The plasma levels of HVA and 3-methoxy-4-hydroxyphenylglycol (MHPG) were observed to have decreased 4 weeks after risperidone administration in manic patients. The levels did not change in depressive patients. The plasma levels of BDNF were decreased in depressive patients compared with manic patients or healthy controls. However, the administration of risperidone did not alter plasma BDNF levels. Copyright © 2006 John Wiley & Sons, Ltd. [source]


A Double-Blind, Placebo-Controlled Study With Quetiapine as Adjunct Therapy With Lithium or Divalproex in Bipolar I Patients With Coexisting Alcohol Dependence

ALCOHOLISM, Issue 10 2010
Mary Stedman
Background:, This study evaluated the efficacy of quetiapine versus placebo as an adjunct to lithium or divalproex in reducing alcohol consumption in patients with bipolar I disorder and coexisting alcohol dependence. Methods:, Male and female outpatients (21 to 60 years) with a history of bipolar I disorder and alcohol dependence were included in this 12-week, placebo-controlled study. Patients treated with lithium or divalproex (ongoing or assigned at screening) were randomized to receive quetiapine (dosed up to 400 mg/d over 7 days, followed by 300 to 800 mg/d flexible dosing until study end) or placebo. The primary outcome measure was the change in the proportion of heavy drinking days from baseline to Week 12 (as derived from the Timeline Followback method). Secondary outcome measures included time to the first consecutive 2 weeks of abstinence, changes from baseline to Week 12 in the proportion of nondrinking days, mean number of standardized drinks per day, and Clinical Global Impressions-Severity of Illness score. Results:, Of 362 enrolled patients (mean 38.6 years), 176 were randomized to receive quetiapine and 186 to placebo. The mean proportion of heavy drinking days at baseline was 0.66 in the quetiapine group and 0.67 in the placebo group. At Week 12, the mean change in the proportion of heavy drinking days was ,0.36 with quetiapine and ,0.36 with placebo (p = 0.93). No statistically significant differences in any of the secondary outcome measures were noted between the quetiapine and placebo groups. The incidence of adverse events was consistent with the previously known tolerability profile of quetiapine. Conclusions:, The efficacy of quetiapine in the treatment of bipolar disorder is already well established. In this study, however, quetiapine added to lithium or divalproex did not result in significantly greater improvement compared with placebo in measures of alcohol use and dependence in patients with bipolar I disorder and alcohol dependence.

Family History of Psychiatric Disorders and Alcohol and Substance Misuse in Patients with Bipolar I Disorder, Substance Use Disorder, or Both

THE AMERICAN JOURNAL ON ADDICTIONS, Issue 3 2007
Alfredo Sbrana MD
Family history data were collected on first-degree relatives of 78 patients with bipolar I disorder (BD) and substance use disorder (SUD), 47 with BD only, and 35 with SUD only. The prevalence of psychiatric disorders was significantly higher in first-degree relatives of patients with BD + SUD (64%) and BD (61%) compared with first-degree relatives of SUD patients (20%). The prevalence of alcohol misuse was significantly higher in first-degree relatives of patients with BD + SUD (23.1%) and SUD alone (28.6%) compared to first-degree relatives of patients with BD (4.3%). Our findings suggest that BD and SUD do not share familial risk factors. [source]


Higher prevalence of bipolar I disorder among Asian and Latino compared to Caucasian patients receiving treatment

ASIA-PACIFIC PSYCHIATRY, Issue 3 2010
Sophia H.J. Hwang MSEd
Abstract Introduction: There are limited data regarding relationships between race/ethnicity and bipolar disorder. This study assessed such relationships in patients receiving treatment in a university clinic. Methods: Demographic, illness characteristics, symptom severity, treatment, and care utilization data were collected from the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) Affective Disorders Evaluation, Mini-International Neuropsychiatric Interview, and the STEP-BD Clinician Rated Packet. Data were compared among 51 Asian, 35 Latino, and 86 Caucasian patients in treatment at the Stanford University Bipolar Disorders Clinic. ,2 tests and analyses of variance were used to assess between-group differences. Results: Asian and Latino compared to Caucasian patients had significantly higher prevalence of bipolar I disorder (58.8% and 60.0% versus 37.2%, respectively). Asian and Latino patients also had a higher prevalence of history of psychosis, but this was related to the excess of bipolar I disorder, becoming non-significant after controlling for bipolar subtype. The racial/ethnic difference in bipolar subtype prevalence did not appear to be secondary to demographic or socioeconomic differences. Discussion: The higher prevalence of bipolar I disorder and thus lower prevalence of bipolar II disorder and bipolar disorder not otherwise specified in Asian and Latino patients may be related to under-diagnosis, misdiagnosis, or care underutilization of patients with milder forms of bipolar disorders. Additional research and public health efforts are warranted to further understand the effects of race and ethnicity on the management of bipolar disorders and to enhance timely and accurate diagnosis, culturally sensitive treatment, and optimal care utilization.

Lamotrigine versus lithium as maintenance treatment in bipolar I disorder: an open, randomized effectiveness study mimicking clinical practice.

BIPOLAR DISORDERS, Issue 5 2010
The 6th trial of the Danish University Antidepressant Group (DUAG-6)

Objectives:, In industry-generated pivotal studies, lamotrigine has been found to be superior to placebo and comparable to lithium in the maintenance treatment of bipolar I disorder. Here, we directly compared lamotrigine to lithium under conditions similar to clinical routine conditions. Methods:, Adult bipolar I disorder patients with at least two episodes within the last five years and an index episode requiring treatment were randomized to lithium (n = 78; doses adjusted to obtain serum levels of 0.5,1.0 mmol/L) or to lamotrigine (n = 77; up-titrated to 400 mg/day) as maintenance treatments. Randomization took place when clinically appropriate, and comedication was allowed within the first six months after randomization. The patients were enrolled from March 2001 to December 2005, and observations were censored December 2006, allowing a subgroup of patients to be followed for more than five years. The primary outcome measure was time to predefined endpoints indicating insufficient maintenance treatment, and the major secondary outcome measure was time to any study endpoint. Data were analyzed primarily by Cox proportional regression models. Results:, For the primary outcome measure, the crude Hazard Rate Ratio (HRR) (lamotrigine relative to lithium) was 0.92 [95% confidence interval (CI): 0.60,1.40]. When the primary endpoints were broken down by polarity, the HRRs (lamotrigine relative to lithium) for mania and depression were, respectively, 1.91 (95% CI: 0.73,5.04) and 0.69 (95% CI: 0.41,1.22). There was no between-group difference in terms of staying in study [HRR: 0.85 (95% CI: 0.61,1.19)]. Most treatment failures occurred within the first 1.5 years of treatment, and, among patients followed for at least five years, practically no patients were maintained successfully on monotherapy with either of the drugs. The lithium-treated patients reported diarrhea, tremor, polyuria, and thirst more frequently. Two cases, probably lamotrigine-related, of benign rash occurred. Conclusions:, No differences in maintenance effectiveness between lithium and lamotrigine could be demonstrated. Lamotrigine was better tolerated than lithium, but apparently this did not influence the outcome. [source]

Bipolar Disord 2010: 12: 557,567. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objective:, To determine if the repeated occurrence of manic episodes in bipolar I disorder (BD-I) patients is associated with reduced cognitive performance, which could in turn imply a worsening in the disorder's evolution. Method:, Cognitive performance in euthymic patients was assessed using attention, memory, and executive function tests on 24 BD-I patients who had experienced only 1 manic episode, on 27 BD-I patients with 2 manic episodes, on 47 BD-I patients with 3 or more manic episodes, and on 66 healthy control subjects. Results:, In BD-I patients, number of manic episodes was positively associated with poorer performance on neurocognitive tests, an association that was not accounted for by depression, disease chronicity, onset, or medication. Significant differences in attention and executive function were found between patients and controls and in those patients who had had just 1 manic episode compared to those who had 3 or more. Conclusion:, The number of manic episodes predicted poor cognitive performance, suggesting that the recurrence of mania may have a long-term neuropsychological impact. Prospective follow-up studies need to be completed to explore this effect further as better treatment adherence may have a protective effect on neurocognitive function. [source]

Bipolar Disord 2010: 12: 230,243. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objectives:, To evaluate the antimanic efficacy and safety of paliperidone extended-release (ER) tablets in patients with bipolar I disorder. Methods:, This study included a 3-week, double-blind, acute treatment phase (paliperidone ER versus placebo, with quetiapine as control), and a 9-week, double-blind, maintenance phase (paliperidone ER versus quetiapine). Patients [n = 493; Young Mania Rating Scale (YMRS) score , 20] were randomized (2:2:1) to flexibly dosed paliperidone ER (3,12 mg/day), quetiapine (400,800 mg/day), or placebo for the acute treatment phase. During the maintenance phase, patients assigned to placebo were switched to paliperidone ER but not included in analysis of efficacy. Results:, Paliperidone ER was superior to placebo at the 3-week endpoint {primary outcome; least-squares mean difference in change from baseline in YMRS scores [95% confidence interval (CI)]: ,5.5 (,7.57; ,3.35); p < 0.001} and noninferior to quetiapine at the 12-week endpoint [least-squares mean difference (95% CI): 1.7 (,0.47; 3.96)]. The median mode dose during the 12-week treatment period was 9 mg for paliperidone ER and 600 mg for quetiapine. The most common (, 10%) treatment-emergent adverse events during the 12-week period were: headache (16%), somnolence (10%), and akathisia (10%) for paliperidone ER; somnolence (21%), sedation and dry mouth (17% each), headache (14%), and dizziness (13%) for quetiapine. Body weight increase , 7% from baseline to 12-week endpoint was 8% with paliperidone ER and 17% with quetiapine. A higher percentage of paliperidone ER (13.9%) versus quetiapine patients (7.5%) ,switched to depression' at the12-week endpoint. Conclusions:, Paliperidone ER (3,12 mg/day) was efficacious and tolerable in the treatment of acute mania. [source]

Bipolar Disord 2010: 12: 244,252. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objectives:, To assess the prevalence and correlates of childhood and adolescent sexual and/or physical abuse (SPA) in bipolar I disorder (BDI) patients treated for a first episode of psychotic mania. Methods:, The Early Psychosis Prevention and Intervention Centre admitted 786 first-episode psychosis patients between 1998 and 2000. Data were collected from patients' files using a standardized questionnaire. A total of 704 files were available; 43 were excluded because of a nonpsychotic diagnosis at endpoint and 3 due to missing data regarding past stressful events. Among 658 patients with available data, 118 received a final diagnosis of BDI and were entered in this study. Results:, A total of 80% of patients had been exposed to stressful life events during childhood and adolescence and 24.9% to SPA; in particular, 29.8% of female patients had been exposed to sexual abuse. Patients who were exposed to SPA had poorer premorbid functioning, higher rates of forensic history, were less likely to live with family during treatment period, and were more likely to disengage from treatment. Conclusions:, SPA is highly prevalent in BDI patients presenting with a first episode of psychotic mania; exposed patients have lower premorbid functional levels and poorer engagement with treatment. The context in which such traumas occur must be explored in order to determine whether early intervention strategies may contribute to diminish their prevalence. Specific psychological interventions must also be developed. [source]

Bipolar Disord 2010: 12: 327,334. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objectives:, To examine the feasibility of collecting course of illness data from patients with bipolar I and II disorder, using weekly text-messaged mood ratings, and to examine the time trajectory of symptom ratings based on this method of self-report. Methods:, A total of 62 patients with bipolar I (n = 47) or II (n = 15) disorder provided mood data in response to weekly cell phone text messages (n = 54) or e-mail prompts (n = 8). Participants provided weekly ratings using the Altman Self-Rating Mania Scale and the Quick Inventory of Depressive Symptoms,Self Report. Patients with bipolar I and II disorder, and men and women, were compared on percentages of time in depressive or manic mood states over up to two years. Results:, Participants provided weekly ratings over an average of 36 (range 1,92) weeks. Compliance with the procedure was 75%. Overall, participants reported depressive symptoms 47.7% of the time compared to 7% of entries reflecting manic symptoms, 8.8% reflecting both depressive and manic symptoms, and 36.5% reflecting euthymic mood. Participants with bipolar I disorder reported more days of depression and were less likely to improve with time than participants with bipolar II disorder. Gender differences observed at the beginning of the study were not observed at follow-up. Conclusions:, The results are similar to those of other longitudinal studies of bipolar disorder that use traditional retrospective, clinician-gathered mood data. Text-message-based symptom monitoring during routine follow-up may be a reliable alternative to in-person interviews. [source]

Bipolar Disord 2010: 12: 116,141. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objective:, To compare antipsychotic and mood stabilizer (MS) efficacy and tolerability in youth and adults with bipolar mania. Methods:, Medline/PubMed search for studies including: (i) youth (< 18 years) or adults (, 18 years); (ii) bipolar I disorder; (iii) double-blind, randomized, placebo-controlled trial (DB-RPCT); (iv) , 12 weeks of treatment; and (v) calculable effect sizes (ES) and/or numbers needed to treat/harm (NNT/NNH) ± 95% confidence intervals (CI). Non-overlapping 95% CIs determined significant group differences. Results:, We identified nine DB-RPCTs in youth (n = 1,609), 5 evaluating second-generation antipsychotics (SGAs) (n = 1,140) and 4 evaluating MSs (n = 469). We also identified 23 DB-RPCTs in adults (n = 6,501), 14 including SGAs (n = 3,297), 5 using haloperidol as an active comparator (n = 580), and 11 including MSs (n = 2,581). Young Mania Rating Scale scores improved significantly more with SGAs than MSs in youth (ES = 0.65, CI: 0.53,0.78 versus 0.24, CI: 0.06,0.41) and adults (ES = 0.48, CI: 0.41,0.55 versus 0.24, CI: 0.17,0.31). After excluding topiramate studies, SGAs had larger ES than MSs only in youth (ES = 0.65, CI: 0.53,0.78 versus 0.20, CI: 0.02,0.39), but not adults (ES = 0.48, CI: 0.41,0.55 versus 0.46, CI: 0.37,0.55). However, in adults SGAs had significantly larger ES regarding Clinical Global Impressions scores than MSs, even without topiramate (ES = 0.75, CI: 0.68,0.82 versus 0.24, CI: 0.07,0.41). Rates of response, remission, and discontinuation due to any reason compared to placebo were similar between medication and age groups, except for more favorable NNTs for remission with SGAs than MSs in adults after excluding topiramate. SGAs caused more weight gain than MSs in youth (ES = 0.53, CI: 0.41,0.66 versus 0.10, CI: ,0.12,0.33), but not in adults (ES = 0.13, CI: 0.05,0.22 versus 0.00, CI: ,0.08,0.08). However, results were heterogeneous and not significant in either age group after excluding topiramate. Nevertheless, SGA-related weight gain was significantly greater in youth than adults. In youth, SGA-related somnolence was greater than with MSs (NNH = 4.7, CI: 3.9,6.0 versus 9.5, CI: 6.3,23.5), and more likely than in adults (NNH = 7.1, CI: 6.1,8.8). Conversely, youth experienced less akathisia with SGAs than adults (NNH = 20.4, CI: 14.1,36.5 versus 10.2, CI: 8.1,13.7), likely due to lower doses/slower titration. Conclusions:, In treating mania, potentially greater short-term efficacy compared to placebo with SGAs versus MS needs to be balanced against increased adverse events, especially in youth. [source]


Asenapine versus olanzapine in acute mania: a double-blind extension study

BIPOLAR DISORDERS, Issue 8 2009
Roger S McIntyre
Objective:, To assess the efficacy and tolerability of asenapine versus olanzapine in the extended treatment of bipolar mania. Methods:, Patients with bipolar I disorder experiencing acute manic or mixed episodes who completed either of two 3-week, double-blind trials with asenapine 5 or 10 mg twice daily, olanzapine 5 to 20 mg once daily, or placebo were eligible for this 9-week, double-blind extension study. Patients receiving active medication in the 3-week trials continued the same regimen; those who had received placebo were blindly switched to asenapine but were assessed for safety outcomes only. The primary efficacy measure was the change from baseline to day 84 on the Young Mania Rating Scale (YMRS) total score in the per-protocol population. Results on the primary efficacy outcome were used to determine the noninferiority of asenapine versus olanzapine. Results:, A total of 504 patients (placebo/asenapine, n = 94; asenapine, n = 181; olanzapine, n = 229) were enrolled in the extension study. At day 84, the mean (SD) change from baseline in YMRS total score was ,24.4 (8.7) for asenapine and ,23.9 (7.9) for olanzapine. Prespecified statistical analysis for noninferiority indicated no significant difference between asenapine and olanzapine. The overall incidence of treatment-emergent adverse events was similar across treatment groups (77% placebo/asenapine, 77% asenapine, 78% olanzapine). Clinically significant weight gain occurred in 10%, 19%, and 31% of the placebo/asenapine, asenapine, and olanzapine groups, respectively. Conclusions:, Asenapine was efficacious, showed noninferiority to olanzapine, and was well tolerated in the extended treatment of patients experiencing manic symptoms associated with bipolar I disorder.

Risperidone for the treatment of acute mania in children and adolescents with bipolar disorder: a randomized, double-blind, placebo-controlled study

BIPOLAR DISORDERS, Issue 7 2009
Magali Haas
Objectives:, To evaluate the efficacy, safety, and tolerability of risperidone monotherapy for the treatment of an acute mixed or manic episode in children and adolescents with bipolar I disorder. Methods:, This randomized, placebo-controlled, double-blind, 3-arm study (N = 169) included children and adolescents (ages 10,17 years) with a DSM-IV diagnosis of bipolar I disorder, experiencing a manic or mixed episode. Study participants were randomized to placebo (n = 58), risperidone 0.5,2.5 mg/day (n = 50), or risperidone 3,6 mg/day (n = 61) for 3 weeks. The primary efficacy measure was change in Young Mania Rating Scale (YMRS) total score from baseline to end point. Safety assessments included adverse event (AE) monitoring and scores on extrapyramidal symptom rating scales. Results:, Improvement in mean YMRS total score was significantly greater in risperidone-treated subjects than in placebo-treated subjects [mean change (SD) ,9.1 (11.0) for placebo; ,18.5 (9.7) for risperidone 0.5,2.5 mg (p < 0.001); ,16.5 (10.3) for risperidone 3,6 mg (p < 0.001)]. The most common risperidone-associated AEs were somnolence, headache, and fatigue. Mean (SD) weight gain was 0.7 (1.9) kg, 1.9 (1.7) kg, and 1.4 (2.4) kg in the placebo, risperidone 0.5,2.5 mg, and risperidone 3,6 mg groups, respectively, during this 3-week study. Conclusions:, At daily doses of 0.5,2.5 mg and 3,6 mg, risperidone was effective and well tolerated in children and adolescents experiencing acute manic or mixed episodes of bipolar I disorder. Results indicate that risperidone 0.5,2.5 mg has a better benefit,risk profile than risperidone 3,6 mg. [source]


An initial report of a new biological marker for bipolar disorder: P85 evoked brain potential

BIPOLAR DISORDERS, Issue 6 2009
Julie V Patterson
Objectives:, Progress toward understanding the neurobiological and genetic underpinnings of bipolar disorder has been limited by the scarcity of potential biological markers that predict its occurrence. A measure of the integrity of brain inhibitory function, sensory gating, measured using the amplitude of the evoked potential at 50 ms to the first of two paired clicks divided by the response to the second, has been characterized as a biological marker for schizophrenia. Currently, no such biological marker exists for bipolar disorder. The goal of this research was to determine how gating of an auditory brain potential at 85 ms (P85), not previously examined in sensory gating studies, differentiated control and patient groups. Methods:, P50 and P85 auditory evoked potentials were collected from individuals diagnosed with schizoaffective disorder (n = 45), paranoid schizophrenia (n = 66), and bipolar I disorder (n = 42) using DSM-IV criteria and the Structured Clinical Interview for DSM-IV; and from 56 healthy controls. Results:, The P85 gating ratio was significantly larger in the bipolar disorder group compared to each of the other groups (F3,204 = 5.47, p = 0.001, and post-hoc tests). The P50 gating ratio was significantly larger for the schizoaffective group than for the control group (F3,204 = 2.81, p = 0.040), but did not differ from the ratio for the schizophrenia, paranoid type (p = 0.08) and bipolar groups. Conclusions:, The previously unstudied P85 gating ratio may provide a new marker specific to bipolar disorder. The findings will promote further studies to investigate the unique contribution of this measure as an endophenotype. [source]


A double-blind, placebo-controlled pilot study of quetiapine for depressed adolescents with bipolar disorder

BIPOLAR DISORDERS, Issue 5 2009
Melissa P DelBello
Objective:, To conduct a pilot study comparing the effects of quetiapine and placebo for the treatment of depressive episodes in adolescents with bipolar I disorder. Method:, Thirty-two adolescents (ages 12,18 years) with a depressive episode associated with bipolar I disorder were randomized to eight weeks of double-blind treatment with quetiapine, 300,600 mg/day, or placebo. This two-site study was conducted from March 2006 through August 2007. The primary efficacy measure was change in Children's Depression Rating Scale,Revised Version (CDRS-R) scores from baseline to endpoint. Secondary efficacy measures included change in CDRS-R scores over the eight-week study period (PROC MIXED), changes from baseline to endpoint in Hamilton Anxiety Rating Scale (HAM-A), Young Mania Rating Scale (YMRS), and Clinical Global Impression,Bipolar Version Severity (CGI-BP-S) scores, as well as response and remission rates. Safety and tolerability were assessed weekly. Results:, There was no statistically significant treatment group difference in change in CDRS-R scores from baseline to endpoint (p = 0.89, effect size =,0.05, 95% confidence interval: ,0.77,0.68), nor in the average rate of change over the eight weeks of the study (p = 0.95). Additionally, there were no statistically significant differences in response (placebo =67% versus quetiapine = 71%) or remission (placebo = 40% versus quetiapine = 35%) rates, or change in HAM-A, YMRS, or CGI-BP-S scores (all p > 0.7) between treatment groups. Dizziness was more commonly reported in the quetiapine (41%) than in the placebo (7%) group (Fisher's exact test, p = 0.04). Conclusions:, The results suggest that quetiapine monotherapy is no more effective than placebo for the treatment of depression in adolescents with bipolar disorder. However, limitations of the study, including the high placebo response rate, may have contributed to our findings and should be considered in the design of future investigations of pharmacological interventions for this population.

Memory functioning in familial bipolar I disorder patients and their relatives

BIPOLAR DISORDERS, Issue 2 2009
Seema Quraishi
Objective:, The aim of this study was to compare the memory function of patients with familial bipolar I disorder (BD I) who had shown psychotic features, their non-psychotic, non-bipolar first-degree relatives, and normal controls. Method:, We assessed 38 patients with a lifetime diagnosis of BD I who had experienced psychotic symptoms, 49 of their non-psychotic, non-bipolar first-degree relatives, and 44 controls. Patients and relatives were from families multiply affected with functional psychotic illness. A five-subtest short form of the Wechsler Adult Intelligence Scale,Revised and three Wechsler Memory Scale subtests were administered to all participants. Results:, BD I patients showed deficits in verbal memory and verbal learning but not in visual memory. Compared to controls, relatives showed worse verbal learning at a statistically significant or suggestive level and performed significantly worse in both immediate and delayed verbal memory. Similar to patients, there were no differences between the relatives and control group for visual memory. Conclusion:, Impaired verbal memory and learning were found in patients and their relatives. These deficits may represent candidate endophenotypic markers for bipolar disorder. [source]


Polarity at illness onset in bipolar I disorder and clinical course of illness

BIPOLAR DISORDERS, Issue 1 2009
Liz Forty
Objectives:, Studies have suggested that episode polarity at illness onset in bipolar disorder may be predictive of some aspects of lifetime clinical characteristics. We here examine this possibility in a large, well-characterized sample of patients with bipolar I disorder. Methods:, We assessed polarity at onset in patients with bipolar I disorder (N = 553) recruited as part of our ongoing studies of affective disorders. Lifetime clinical characteristics of illness were compared in patients who had a depressive episode at first illness onset (n = 343) and patients who had a manic episode at first illness onset (n = 210). Results:, Several lifetime clinical features differed between patients according to the polarity of their onset episode of illness. A logistic regression analysis showed that the lifetime clinical features significantly associated with a depressive episode at illness onset in our sample were: an earlier age at illness onset; a predominantly depressive polarity during the lifetime; more frequent and more severe depressive episodes; and less prominent lifetime psychotic features. Conclusions:, Knowledge of pole of onset may help the clinician in providing prognostic information and management advice to an individual with bipolar disorder. [source]


An fMRI investigation of working memory and sadness in females with bipolar disorder: a brief report

BIPOLAR DISORDERS, Issue 8 2008
Thilo Deckersbach
Objective:, Functional magnetic resonance imaging (fMRI) studies have documented abnormalities in the dorsolateral prefrontal cortex (DLPFC) and anterior cingulate cortex in bipolar disorder in the context of working memory tasks. It is increasingly recognized that DLPFC regions play a role in mood regulation and the integration of emotion and cognition. The purpose of the present study was to investigate with fMRI the interaction between acute sadness and working memory functioning in individuals with bipolar disorder. Methods:, Nine depressed individuals with DSM-IV bipolar I disorder (BP-I) and 17 healthy control participants matched for age, gender, education, and IQ completed a 2-back working memory paradigm under no mood induction, neutral state, or acute sadness conditions while undergoing fMRI scanning. Functional MRI data were analyzed with SPM2 using a random-effects model. Results:, Behaviorally, BP-I subjects performed equally well as control participants on the 2-back working memory paradigm. Compared to control participants, individuals with BP-I were characterized by more sadness-specific activation increases in the left DLPFC (BA 9/46) and left dorsal anterior cingulate (dACC). Conclusions:, Our study documents sadness-specific abnormalities in the left DLPFC and dACC in bipolar disorder that suggest difficulties in the integration of emotion (sadness) and cognition. These preliminary findings require further corroboration with larger sample sizes of medication-free subjects. [source]


Missed bipolarity and psychiatric comorbidity in women with postpartum depression

BIPOLAR DISORDERS, Issue 6 2008
Verinder Sharma
Objective:, To investigate the diagnostic profile of women referred for postpartum depression. Methods:, Fifty-six women seen consecutively with the referral diagnosis of postpartum depression were administered structured instruments to gather information about their DSM-IV Axis I diagnoses. Results:, In terms of frequency of occurrence, the primary diagnoses in this sample were: major depressive disorder (46%), bipolar disorder not otherwise specified (29%), bipolar II disorder (23%), and bipolar I disorder (2%). A current comorbid disorder, with no lifetime comorbidity, occurred among 32% of the sample; by contrast, lifetime comorbidity alone (i.e., with no currently comorbid disorder) was found among 27%. Both a lifetime and a current comorbidity were found among 18% of the women, and 23% had no comorbid disorder. The most frequently occurring current comorbid disorder was an anxiety disorder (46%), with obsessive-compulsive disorder (62%) being the most common type of anxiety disorder. For lifetime comorbidity, substance use (20%) and anxiety disorders (12%) were the two most common. Over 80% of patients who scored positive on either the Highs Scale or the Mood Disorder Questionnaire met the diagnostic criteria for a bipolar disorder. Conclusion:, The results suggest that postpartum depression is a heterogeneous entity and that misdiagnosis of bipolar disorder in the postpartum period may be quite common. The findings have important clinical implications, which include the need for early detection of bipolarity through the use of reliable and valid assessment instruments, and implementation of appropriate prevention and treatment strategies.

Substance use disorders among adolescents with bipolar spectrum disorders

BIPOLAR DISORDERS, Issue 4 2008
Benjamin I Goldstein
Objective:, We set out to examine the prevalence and correlates of substance use disorders (SUD) in a large sample of adolescents with bipolar disorder (BP). Methods:, Subjects were 249 adolescents ages 12 to 17 years old who fulfilled DSM-IV criteria for bipolar I disorder [(BPI), n = 154], or bipolar II disorder [(BPII), n = 25], or operationalized criteria for BP not otherwise specified [(BP NOS), n = 70], via the Schedule for Affective Disorders and Schizophrenia for School-Aged Children (K-SADS). As part of the multi-site Course and Outcome of Bipolar Youth study, demographic, clinical, and family history variables were measured via intake clinical interview with the subject and a parent/guardian. Results:, The lifetime prevalence of SUD among adolescents with BP was 16% (40/249). Results from univariate analyses indicated that subjects with, as compared to without, SUD were significantly less likely to be living with both biological parents, and that there was significantly greater lifetime prevalence of physical abuse, sexual abuse, suicide attempts, conduct disorder, and posttraumatic stress disorder among subjects with SUD. Subjects with SUD reported significantly greater 12-month prevalence of trouble with police, and females with SUD reported significantly greater 12-month prevalence of pregnancy and abortion. Significant predictors of SUD in a logistic regression model included living with both biological parents (lower prevalence), conduct disorder and suicide attempts (increased prevalence). In logistic regression analyses controlling for demographic differences and conduct disorder, SUD remained significantly associated with trouble with police, whereas the association of SUD with pregnancy and abortion was reduced to a statistical trend. The prevalence of SUD was not significantly different among child- versus adolescent-onset BP subjects. Conclusions:, SUD among adolescents with BP is associated with profound hazards including suicide attempts, trouble with police, and teenage pregnancy and abortion. [source]


Neurocognitive profiles in bipolar I and bipolar II disorder: differences in pattern and magnitude of dysfunction

BIPOLAR DISORDERS, Issue 2 2008
Carmen Simonsen
Objectives:, Studies on neurocognitive functioning in bipolar disorder, reporting deficits in memory, attention, and executive functioning, have primarily focused on bipolar I disorder. The aim of this study was to examine whether patients with bipolar I and bipolar II disorder have different neurocognitive profiles. Methods:, Forty-two patients with bipolar I disorder, 31 patients with bipolar II and 124 healthy controls, from a large ongoing study on psychotic disorders, were included. Neurocognitive function was measured with a comprehensive neuropsychological test battery. Results:, The bipolar I group performed significantly poorer than the healthy control group and the bipolar II group on all measures of memory. Compared with the control group, the bipolar I group also had significantly reduced performance on most measures of attention and executive functioning, while the bipolar II group only had a significantly reduced performance on a subset of these measures. On average, 24% of the bipolar I group had clinically significant cognitive impairment (,1.5 SD below the control group mean) across measures, compared with 13% of the bipolar II group. Conclusions:, Patients with bipolar I and bipolar II disorder in this study have different neurocognitive profiles. Bipolar I patients have more widespread cognitive dysfunction both in pattern and magnitude, and a higher proportion has clinically significant cognitive impairments compared with patients with bipolar II. This may suggest neurobiological differences between the two bipolar subgroups. [source]


Initiation of stimulant and antidepressant medication and clinical presentation in juvenile bipolar I disorder

BIPOLAR DISORDERS, Issue 2 2008
Maria E Pagano
Objectives:, The primary purpose of this study was to examine the extent to which the initiation of stimulant and antidepressant medication was associated with the subsequent onset of juvenile bipolar I disorder (BP I). Another aim was to investigate differences in clinical presentation between youths prescribed stimulant or antidepressant medication before and after the onset of juvenile BP I disorder. Methods:, Youths between the ages of 5 and 17 years meeting full, unmodified DSM-IV diagnostic symptom criteria for BP were included in this study. Data regarding the age of onset of BP I, psychiatric comorbidities, and current symptoms of mania and depression were obtained. Medication history was recorded as part of the assessment interview with parents and youths. Results:, Of the 245 youths with BP I, 65% (n = 160) were treated with stimulant medication; 32% (56/173) were treated after the onset of BP I, and 19% (32/173) were treated before the onset of BP I. Forty-six percent (113/245) were treated with antidepressant medication; 33% (67/206) were treated after the onset of BP I, and 3% (7/206) were treated before the onset of BP I. Patients who were treated with stimulants after the onset of BP I were significantly more likely to be younger (p < 0.0001). Patients who were treated with antidepressants before the onset of BP I were significantly more likely to be older and to have lower levels of mania on the Young Mania Rating Scale at assessment (p < 0.01). Conclusions:, Data from this retrospective case series do not support the association between initial stimulant or antidepressant use and the onset of BP I or presenting symptoms of depression or manic symptoms.

Psychotic phenomena in 257 young children and adolescents with bipolar I disorder: delusions and hallucinations (benign and pathological)

BIPOLAR DISORDERS, Issue 1 2008
Rebecca Tillman
Objectives:, In contrast to studies of adult bipolar I disorder (BP-I), there is a paucity of data on psychotic phenomena in child BP-I. Therefore, the aim of this work was to describe delusions and hallucinations in pediatric BP-I. Methods:, Subjects were 257 participants, aged 6,16, in either of two large, ongoing, NIMH-funded studies, ,Phenomenology and Course of Pediatric Bipolar Disorders' or ,Treatment of Early Age Mania (TEAM)'. All subjects had current DSM-IV BP-I (manic or mixed phase) with a Children's Global Assessment Scale score ,60 (definite clinical impairment), and all had cardinal mania symptoms (i.e., elation and/or grandiosity). Comprehensive assessments included the Washington University in St. Louis Kiddie Schedule for Affective Disorders and Schizophrenia (WASH-U-KSADS), which was administered to parents about their children and separately to children about themselves by experienced research clinicians. The WASH-U-KSADS contains modules for developmentally child-age-specific manifestations of numerous categories of psychotic phenomena. Results:, Psychosis was present in 76.3% (n = 196) of subjects, which included 38.9% (n = 100) with delusions, 5.1% (n = 13) with pathological hallucinations, and 32.3% (n = 83) with both. The most common delusion was grandiose (67.7%, n = 174), and the most common pathological hallucination was visual (16.0%, n = 41). Benign hallucinations occurred in 43.6% (n = 112). A median split by age yielded 6,9 year-olds (n = 139) and 10,16 year-olds (n = 118). Analyses of these two groups, and of 6, 7, 8, and 9 year-olds separately, found no significant differences in psychotic phenomena. Conclusions:, Counterintuitively, psychosis was equally prevalent in 6,9 compared to 10,16 year-olds. High prevalence of psychosis in child BP-I warrants focus in intervention strategies and is consistent with increasing evidence of the severity of child-versus adult-onset BP-I. [source]


The spectrum of substance abuse in bipolar disorder: reasons for use, sensation seeking and substance sensitivity

BIPOLAR DISORDERS, Issue 3 2007
Jacopo V Bizzarri
Objectives:, To examine the spectrum of alcohol and substance abuse, including reasons for use, in patients with bipolar I disorder, compared with patients with substance use disorder and healthy controls, with a specific focus on the relationship between substance use, substance sensitivity, other comorbid psychiatric symptoms and traits related to sensation seeking. Methods:, This study included 104 patients with bipolar I disorder (BPD I), of whom 57 (54.8%) met DSM-IV criteria for lifetime alcohol or substance use disorder (BPD + SUD), 35 patients with substance use disorder (SUD) and no psychiatric disorder and 50 healthy controls. Assessments included the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) and the Structured Clinical Interview for the Spectrum of Substance Use (SCI-SUBS). Results:, Patients with BPD + SUD and SUD had significantly higher scores on the SCI-SUBS domains of self-medication, substance sensitivity and sensation seeking compared with patients with BPD and healthy controls. Reasons for substance use did not differ between patients with BPD + SUD and patients with SUD. Those most frequently cited were: improving mood; relieving tension; alleviating boredom; achieving/maintaining euphoria; and increasing energy. Conclusions:, Recourse to substances is associated with increased mood and anxiety symptoms, substance sensitivity, and sensation seeking among patients with BPD + SUD and SUD. Substance sensitivity and sensation seeking traits should be investigated in all patients with BPD as possible factors associated with a development of SUD, in order to warn patients of the specific risks related to improper use of medications and substances.
