A history of childhood attention-deficit hyperactivity disorder (ADHD) impacts clinical outcome in adult bipolar patients regardless of current ADHD

ACTA PSYCHIATRICA SCANDINAVICA, Issue 3 2009
E. Rydén
Objective:, The occurrence of comorbid attention-deficit hyperactivity disorder (ADHD) might have an impact of the course of the bipolar disorder. Method:, Patients with bipolar disorder (n = 159) underwent a comprehensive evaluation with respect to affective symptoms. Independent psychiatrists assessed childhood and current ADHD, and an interview with a parent was undertaken. Results:, The prevalence of adult ADHD was 16%. An additional 12% met the criteria for childhood ADHD without meeting criteria for adult ADHD. Both these groups had significantly earlier onset of their first affective episode, more frequent affective episodes (except manic episodes), and more interpersonal violence than the bipolar patients without a history of ADHD. Conclusion:, The fact that bipolar patients with a history of childhood ADHD have a different clinical outcome than the pure bipolar group, regardless of whether the ADHD symptoms remained in adulthood or not, suggests that it represent a distinct early-onset phenotype of bipolar disorder.

Neurocognitive test performance predicts functional recovery from acute exacerbation leading to hospitalization in bipolar disorder

BIPOLAR DISORDERS, Issue 1-2 2007
Judith Jaeger
Objective:, Bipolar disorder (BPD) is associated with significant functional morbidity at a rate which is particularly elevated among patients discharged from hospital. The aim of this study was to examine the degree to which neurocognitive test performance, measured following hospitalization for an acute affective episode, is predictive of functional recovery 1 year later. Methods:, Seventy-eight Zucker Hillside Hospital patients aged 18,59 years and having Structured Clinical Interview for DSM-IV diagnosis of bipolar I disorder (BPD I), bipolar II disorder (BPD II) or BPD not otherwise specified (NOS) confirmed through a rigorous diagnosis consensus procedure, underwent a comprehensive neurocognitive test battery after initial stabilization (baseline) and were followed for at least 12 months (follow-up). Hamilton Depression Rating Scale (HAM-D) and Clinician-Administered Rating Scale for Mania (CARS-M) ratings were made at baseline and follow-up. At follow-up, functionality was assessed using the Multidimensional Scale for Independent Functioning (MSIF). Logistic regression was used to examine the predictive value of each of six validated neurocognitive domains for determining functionality (MSIF) at follow-up. Baseline and follow-up HAM-D and CARS-M were entered as covariates as was number of days between baseline and follow-up. Results:, Attention and Ideational Fluency were significantly predictive of functional recovery 12 months later. Residual mania but not depression was associated with 12-month MSIF rating. Lithium and benzodiazepine treatment at the time of neurocognitive testing did not affect the results. Conclusions:, This is the first study examining the predictive value of neurocognitive deficits, independent of residual mania or depression, for long-term functional recovery following hospitalization. Selective neurocognitive deficits are predictive of long-term functional recovery and, as such, should be candidate targets in treatment and rehabilitation programs. [source]

Acute treatment outcomes in patients with bipolar I disorder and co-morbid borderline personality disorder receiving medication and psychotherapy

BIPOLAR DISORDERS, Issue 2 2005
Holly A Swartz
Objective:, Patients suffering from both bipolar I disorder and borderline personality disorder (BPD) pose unique treatment challenges. The purpose of this matched case,control study was to compare acute treatment outcomes of a sample of patients who met standardized diagnostic criteria for both bipolar I disorder and BPD (n = 12) to those who met criteria for bipolar I disorder only (n = 58). Method:, Subjects meeting criteria for an acute affective episode were treated with a combination of algorithm-driven pharmacotherapy and weekly psychotherapy until stabilization (defined as four consecutive weeks with a calculated average of the 17-item version of the Hamilton Rating Scale for Depression and Bech-Rafaelsen Mania scale totaling ,7). Results:, Only three of 12 (25%) bipolar-BPD patients achieved stabilization, compared with 43 of 58 (74%) bipolar-only patients. Two of the three bipolar-BPD patients who did stabilize took over 95 weeks to do so, compared with a median time-to-stabilization of 35 weeks in the bipolar-only group. The bipolar-BPD group received significantly more atypical mood-stabilizing medications per year than the bipolar-only group (Z = 4.3, p < 0.0001). Dropout rates in the comorbid group were high. Conclusions:, This quasi-experimental study suggests that treatment course may be longer in patients suffering from both bipolar I disorder and BPD. Some patients improved substantially with pharmacotherapy and psychotherapy, suggesting that this approach is worthy of further investigation. [source]

Comorbidity of obsessive-compulsive disorder in recovered inpatients with bipolar disorder

BIPOLAR DISORDERS, Issue 1 2000
Stephanie Krüger
Objective: To determine the frequency of obsessive-compulsive disorder (OCD) in inpatient subjects with bipolar disorder (BD) and to examine the clinical characteristics of BD subjects with OCD. Method: The sample consisted of 143 inpatient subjects with DSM-III-R BD-I and BD-NOS (BD-II), recovered from a current episode of either depression or mania. Demographic and clinical variables were obtained on the day of admission. Current comorbid conditions including OCD were determined by the Structured Clinical Interview for DSM-III-R following recovery from the acute affective episode. Results: The frequency of current OCD was 7% (N=10). All BD subjects with OCD were BD-II, were male, and had a diagnosis of current dysthymia. They had fewer episodes and a higher incidence of prior suicide attempts than bipolar subjects without OCD. None of the bipolar subjects with OCD fulfilled criteria for cyclothymia. Conclusions: Our findings suggest that BD-II, OCD, dysthymia, and suicidality cluster together in some subjects with BD. We discuss the clinical implications of our findings. [source]

The impact of age at onset of bipolar I disorder on functioning and clinical presentation

ACTA NEUROPSYCHIATRICA, Issue 4 2009
Frances Biffin
Objectives: Recent studies have proposed the existence of three distinct subgroups of bipolar 1 disorder based on age at onset (AAO). The present study aims to investigate potential clinical and functional differences between these subgroups in an Australian sample. Methods: Participants (n = 239) were enrolled in the Bipolar Comprehensive Outcomes Study (BCOS), a 2-year longitudinal, observational, cross-sectional study. Assessment measures included the Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HAMD21), Clinical Global Impressions Scale (CGI-BP), SF-36, SLICE/Life Scale, and the EuroQol (EQ-5D). Participants were also asked about their age at the first major affective episode. Results: Three AAO groups were compared: early (AAO < 20, mean = 15.5 ± 2.72; 44.4% of the participants); intermediate (AAO 20,39, mean = 26.1 ± 4.8; 48.14% of the participants) and late (AAO > 40, mean = 50.6 ± 9.04; 7.4% of the participants). Higher rates of depression, suicidal ideation and binge drinking were reported by the early AAO group. This group also reported poorer quality of life in a number of areas. The early AAO group had a predominant depressive initial polarity and the intermediate group had a manic predominance. Conclusion: Early AAO is associated with an adverse outcome. [source]

Neuropsychological dysfunction in bipolar affective disorder: a critical opinion

BIPOLAR DISORDERS, Issue 3 2005
Jonathan Savitz
Data from the imaging literature have led to suggestions that permanent structural brain changes may be associated with bipolar disorder. Individuals diagnosed with bipolar disorder display deficits on a range of neuropsychological tasks in both the acute and euthymic phases of illness, and correlations between experienced number of affective episodes and task performance are commonly reported. These findings have renewed interest in the neuropsychological profile of individuals with bipolar disorder, with deficits of attention, learning and memory, and executive function, asserted to be present. This paper critically reviews five different potential causes of neurocognitive dysfunction in bipolar disorder: (i) iatrogenic, (ii) acute functional changes associated with depression or mania, (iii) permanent structural lesions of a neurodegenerative origin, (iv) permanent structural lesions that are neurodevelopmental in origin, and (v) permanent functional changes that are most likely genetic in origin. Although the potential cognitive effects of residual symptomatology and long-term medication use cannot be entirely excluded, we conclude that functional changes associated with genetically driven population variation in critical neural networks underpin both the neurocognitive and affective symptoms of bipolar disorder. The philosophical implications of this conclusion for neuropsychology are briefly discussed. [source]

A survival analysis for recurrent events in psychiatric research

BIPOLAR DISORDERS, Issue 2 2004
Christopher Baethge
Objectives:, Time to first recurrence, as analyzed by the Kaplan,Meier (KM) survival analysis, is a commonly applied statistical method in psychiatric research. However, many psychiatric disorders are characterized not by a single event, but rather by recurrent events, such as multiple affective episodes. This study aims to demonstrate a method of survival analysis that takes multiple recurrences into account. Methods:, We examined data on sex differences in a sample of 181 patients undergoing prophylactic treatment with lithium or carbamazepine (serum level assayed) for bipolar disorder (ICD-10). The classical KM method was compared with an approach developed by Peña, Strawderman and Hollander (PSH) that uses recurrent event data to estimate survival function. Results:, The results obtained with the multiple events method differed considerably from those acquired using the standard KM analysis. When taking recurrent event data into account, the probability of remaining well was lower and survival times were longer. In addition, whereas the standard KM analysis indicated that male patients had a higher likelihood of remaining well, the alternative method revealed that both sexes were similarly likely to remain well. Conclusions:, Survival analysis techniques that take recurrent events into account are potentially important instruments for the study of psychiatric conditions characterized by multiple recurrences. In many cases, the standard KM analysis appears to provide only a rough approximation of the course of illness. [source]

Objectives: The aim of the study was to assess the prophylactic effect of long-term lithium administration in patients with bipolar mood disorders entering treatment in the 1970s and 1980s at the outpatient clinic of the Department of Psychiatry, University of Medical Sciences, Poznan, Poland. Methods: The clinical characteristics of two groups of patients before and during lithium therapy were compared, namely, the 60 bipolar patients who entered lithium prophylaxis in the 1970s and 49 patients who entered in the 1980s. Both groups received the drug over a 10-year period. Results: The patients who entered lithium in the 1970s had fewer previous episodes of depression and more of mania than the patients who entered the therapy in the 1980s, although the total number of affective episodes was similar in both groups. The overall prophylactic efficacy of lithium over a 10-year period of administration was similar in both groups, except for a trend towards a greater number of depressive episodes in the first year of lithium prophylaxis in the 1980s group. The excellent lithium responders constituted 35% of the 1970s patients and 27% of those in the 1980s group. The 1970s patients were maintained on a higher level of serum lithium compared to the patients in the 1980s group and had more lithium-induced side effects. Conclusions: A decrease in lithium prophylactic efficacy in consecutive decades was not observed. Small differences between the bipolar patients entering lithium therapy in the 2 decades were observed in terms of the previous history of illness and during the course of lithium administration.
