The role of panic attacks in acute stress disorder in children,

JOURNAL OF TRAUMATIC STRESS, Issue 6 2007
Emma Sinclair
This study examined the role of peritraumatic panic symptoms during trauma in childhood acute stress. Children (N = 60) who had suffered traumatic injury were administered the Child Acute Stress Reaction Questionnaire, the Child Depression Inventory, and the Physical Reactions Scale to index panic attacks that occurred during the trauma. Panic attacks were experienced during their trauma by 100% of participants with acute stress reactions and 24% of participants without stress reactions. Panic attacks during trauma accounted for 28% of the variance of acute stress reactions, with an additional variance accounted for by age, time since the accident, and dysphoria. These findings are discussed in terms of fear conditioning models of posttraumatic stress. [source]

Correlation of panic attacks and hostility in chronic schizophrenia

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 4 2001
Ching-Yen Chen MD
Abstract The aim of this study was to investigate the relationship between panic attacks and hostility in patients with chronic schizophrenia. Thirty-two patients with a minimum 2-year history of treatment for schizophrenia were interviewed. The patients took mood stablizers lithium, carbamazepine and valproate adjunctively for hostility and anger attacks. Panic attacks were defined by Structure Clinical Interview of DSM-IV. Severity of psychopathology was assessed by the Hamilton Depression Rating Scale (HDRS) and Brief Psychiatric Rating Scale (BPRS). Functional level was assessed by the Global Assessment of Functioning Scale (GAF). Eight (25%) patients met the diagnostic criteria for panic attacks (DSM-IV) with affective symptoms including hostility and sudden spells of anger. Their HDRS scores were significantly higher (P < 0.01), and GAF scores were significantly lower (P < 0.05) than those of patients without panic attacks. Patients with panic attacks displayed significantly higher hostility in the score of the BPRS (P = 0.01). Those who received higher doses of neuroleptics were more likely to be considered hostile. Multivariate analysis revealed that panic attacks were correlated with more severe depression, greater hostility and lower GAF scores. The results suggest that increased hostility and anger spells may be symptoms of panic attacks, which are overlooked by psychiatrists. [source]

Panic comorbidity with bipolar disorder: what is the manic,panic connection?

BIPOLAR DISORDERS, Issue 6 2006
Dean F MacKinnon
Context:, Bipolar/panic comorbidity has been observed in clinical, community and familial samples. As both are episodic disorders of affect regulation, the common pathophysiological mechanism is likely to involve deficits in amygdala-mediated, plasticity-dependent emotional conditioning. Evidence:, Neuronal genesis and synaptic remodeling occur in the amygdala; bipolar and panic disorders have both been associated with abnormality in the amygdala and related structures, as well as in molecules that modulate plasticity, such as serotonin, norepinephrine, brain-derived neurotrophic factor (BDNF) and corticotrophin releasing factor (CRF). These biological elements are involved in behavioral conditioning to threat and reward. Model:, Panic attacks resemble the normal acute fear response, but are abnormally dissociated from any relevant threat. Abnormal reward-seeking behavior is central to both manic and depressive syndromes. Appetites can be elevated or depressed; satisfaction of a drive may fail to condition future behavior. These dissociations may be the result of deficits in plasticity-dependent processes of conditioning within different amygdala subregions. Conclusions:, This speculative model may be a useful framework with which to connect molecular, cellular, anatomic and behavioral processes in panic and bipolar disorders. The primary clinical implication is that behavioral treatment may be critical to restore function in some bipolar patients who respond only partially to medications. [source]

Panic disorder: from respiration to the homeostatic brain

ACTA NEUROPSYCHIATRICA, Issue 2 2004
Giampaolo Perna
There is some experimental evidence to support the existence of a connection between panic and respiration. However, only recent studies investigating the complexity of respiratory physiology have revealed consistent irregularities in respiratory pattern, suggesting that these abnormalities might be a vulnerability factor to panic attacks. The source of the high irregularity observed, together with unpleasant respiratory sensations in patients with panic disorder (PD), is still unclear and different underlying mechanisms might be hypothesized. It could be the result of compensatory responses to abnormal respiratory inputs or an intrinsic deranged activity in the brainstem network shaping the respiratory rhythm. Moreover, since basic physiological functions in the organism are strictly interrelated, with reciprocal modulations and abnormalities in cardiac and balance system function having been described in PD, the respiratory findings might arise from perturbations of these other basic systems or a more general dysfunction of the homeostatic brain. Phylogenetically ancient brain circuits process physiological perceptions/sensations linked to homeostatic functions, such as respiration, and the parabrachial nucleus might filter and integrate interoceptive information from the basic homeostatic functions. These physiological processes take place continuously and subconsciously and only occasionally do they pervade the conscious awareness as ,primal emotions'. Panic attacks could be the expression of primal emotion arising from an abnormal modulation of the respiratory/homeostatic functions. [source]

Diversity of effective treatments of panic attacks: what do they have in common?,

DEPRESSION AND ANXIETY, Issue 1 2010
Walton T. Roth M.D.
Abstract By comparing efficacious psychological therapies of different kinds, inferences about common effective treatment mechanisms can be made. We selected six therapies for review on the basis of the diversity of their theoretical rationales and evidence for superior efficacy: psychoanalytic psychotherapy, hypercapnic breathing training, hypocapnic breathing training, reprocessing with and without eye-movement desensitization, muscle relaxation, and cognitive behavior therapy. The likely common element of all these therapies is that they reduce the immediate expectancy of a panic attack, disrupting the vicious circle of fearing fear. Modifying expectation is usually regarded as a placebo mechanism in psychotherapy, but may be a specific treatment mechanism for panic. The fact that this is seldom the rationale communicated to the patient creates a moral dilemma: Is it ethical for therapists to mislead patients to help them? Pragmatic justification of a successful practice is a way out of this dilemma. Therapies should be evaluated that deal with expectations directly by promoting positive thinking or by fostering non-expectancy. Depression and Anxiety, 2010. Published 2009 Wiley-Liss, Inc.

Pneumomediastinum simulating a panic attack in a patient with anorexia nervosa

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 1 2003
Anita Karim
Abstract Objective Pneumomediastinum is a rare complication of anorexia nervosa. Although the mechanism is unknown, severe malnutrition may affect lung mechanics by altering the connective tissue, predisposing to pneumomediastinum. Method We describe a young male with anorexia nervosa and panic disorder who presented with symptoms similar to those of a panic attack and was diagnosed with spontaneous pneumomediastinum. Results This case illustrates the importance of considering pneumomediastinum in the differential diagnosis of panic attack in patients with eating disorders. Discussion Although spontaneous pneumomediastinum has a generally benign course, it must be differentiated from the potentially life-threatening secondary pneumomediastinum due to an esophageal tear. © 2002 by Wiley Periodicals, Inc.

Smaller amygdala is associated with anxiety in patients with panic disorder

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 3 2009
Fumi Hayano phd
Aims:, Anxiety a core feature of panic disorder, is linked to function of the amygdala. Volume alterations in the brain of patients with panic disorder have previously been reported, but there has been no report of amygdala volume association with anxiety. Methods:, Volumes of hippocampus and amygdala were manually measured using magnetic resonance imaging obtained from 27 patients with panic disorder and 30 healthy comparison subjects. In addition the amygdala was focused on, applying small volume correction to optimized voxel-based morphometry (VBM). State,Trait Anxiety Inventory and the NEO Personality Inventory Revised were also used to evaluate anxiety. Results:, Amygdala volumes in both hemispheres were significantly smaller in patients with panic disorder compared with control subjects (left: t = ,2.248, d.f. = 55, P = 0.029; right: t = ,2.892, d.f. = 55, P = 0.005). VBM showed that structural alteration in the panic disorder group occurred on the corticomedial nuclear group within the right amygdala (coordinates [x,y,z (mm)]: [26,,6,,16], Z score = 3.92, family-wise error-corrected P = 0.002). The state anxiety was negatively correlated with the left amygdala volume in patients with panic disorder (r = ,0.545, P = 0.016). Conclusions:, These findings suggested that the smaller volume of the amygdala may be associated with anxiety in panic disorder. Of note, the smaller subregion in the amygdala estimated on VBM could correspond to the corticomedial nuclear group including the central nucleus, which may play a crucial role in panic attack.

Persistent generalized anxiety after brief exposure to the dopamine antagonist metoclopramide

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 2 2007
MICHAEL KLUGE md
Abstract The authors describe a 31-year-old woman who developed persistent generalized anxiety after brief exposure to the dopamine antagonist metoclopramide. Independently of that, she had experienced a panic attack followed by dystonias, shortly after a single dose of that drug, 17 years before. Both temporal association and recurrence of anxiety symptoms after re-challenge with metoclopramide suggest a causal relationship. The case might provide an initial piece of evidence that dopaminergic neurotransmission can be involved in the pathogenesis of generalized anxiety disorder. [source]

Prediction of first episode of panic attack among white-collar workers

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 2 2005
AKIRA WATANABE md
Abstract, The purpose of the present study was to elucidate a longitudinal matrix of the etiology for first-episode panic attack among white-collar workers. A path model was designed for this purpose. A 5-year, open-cohort study was carried out in a Japanese company. To evaluate the risk factors associated with the onset of a first episode of panic attack, the odds ratios of a new episode of panic attack were calculated by logistic regression. The path model contained five predictor variables: gender difference, overprotection, neuroticism, lifetime history of major depression, and recent stressful life events. The logistic regression analysis indicated that a person with a lifetime history of major depression and recent stressful life events had a fivefold and a threefold higher risk of panic attacks at follow up, respectively. The path model for the prediction of a first episode of panic attack fitted the data well. However, this model presented low accountability for the variance in the ultimate dependent variables, the first episode of panic attack. Three predictors (neuroticism, lifetime history of major depression, and recent stressful life events) had a direct effect on the risk for a first episode of panic attack, whereas gender difference and overprotection had no direct effect. The present model could not fully predict first episodes of panic attack in white-collar workers. To make a path model for the prediction of the first episode of panic attack, other strong predictor variables, which were not surveyed in the present study, are needed. It is suggested that genetic variables are among the other strong predictor variables. A new path model containing genetic variables (e.g. family history etc.) will be needed to predict the first episode of panic attack. [source]

Factors associated with the development of panic attack and panic disorder: Survey in the Japanese population

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 2 2005
HISANOBU KAIYA md
Abstract, Environmental factors, in addition to genetic factors, may be related to the development of panic attack (PA) and panic disorder (PD). Previous studies suggested that there may be seasonal variation in the onset of PA/PD and possibly a higher prevalence of PA/PD in colder areas. Also observed were lactate-induced PA and elevated serum cholesterol in PD patients. These suggest that living environment and lifestyle, such as weather conditions, preference of food and physical exercise, might play a role in the occurrence of PA and PD. The present study explored the association of such candidate factors with the development of PA and PD in 4000 Japanese subjects, using a questionnaire. The subjects were recruited from the general population of Japan, using stratified random sampling. Logistic regression with stepwise selection of variables was employed for statistical analysis. Variables including ,dislike of physical exercise', mostly in female subjects, and ,living in areas with longer winter', in male subjects, were suggested for associations with PA and PD among the candidate factors. The result is preliminary but indicates that lifestyle such as like/dislike of physical exercise and environmental factors including weather conditions could play a partial role in the development of PA and PD. Further investigations are required before firm conclusions can be reached. [source]

Frequency of fainting, vomiting and incontinence in panic disorder: A descriptive study

CLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 3 2007
Sheryl M. Green
Little is known about how often individuals with panic disorder (PD) actually experience the physical catastrophes that they fear (e.g., fainting, vomiting, incontinence). This study investigated the frequency of such events in PD and the circumstances under which they occur. A systematic chart review of 574 consecutive patients diagnosed with PD was completed. Nineteen out of 35 patients who had previously reported a history of fainting, vomiting or incontinence (i.e., loss of bowel or bladder control) during a panic attack were interviewed by telephone. Of this sample, 11 confirmed a history of fainting, four confirmed a history of vomiting and four confirmed a history of incontinence during at least one previous panic attack. Four of these individuals reported more than one type of event and several others reported that they had only come close to experiencing these feared events. Participants also reported on the timing of these events (relative to their panic attacks), the circumstances under which the events occurred, as well as possible causes and outcomes of the events. Although rare, catastrophic events such as fainting, vomiting and incontinence appear to occur in the context of panic attacks for some individuals. The implications for cognitive behavioural treatment of PD are discussed. Copyright © 2007 John Wiley & Sons, Ltd. [source]

Panic disorder: a review of DSM-IV panic disorder and proposals for DSM-V,

DEPRESSION AND ANXIETY, Issue 2 2010
Michelle G. Craske Ph.D
Abstract This review covers the literature since the publication of DSM-IV on the diagnostic criteria for panic attacks (PAs) and panic disorder (PD). Specific recommendations are made based on the evidence available. In particular, slight changes are proposed for the wording of the diagnostic criteria for PAs to ease the differentiation between panic and surrounding anxiety; simplification and clarification of the operationalization of types of PAs (expected vs. unexpected) is proposed; and consideration is given to the value of PAs as a specifier for all DSM diagnoses and to the cultural validity of certain symptom profiles. In addition, slight changes are proposed for the wording of the diagnostic criteria to increase clarity and parsimony of the criteria. Finally, based on the available evidence, no changes are proposed with regard to the developmental expression of PAs or PD. This review presents a number of options and preliminary recommendations to be considered for DSM-V. Depression and Anxiety, 2010. © 2010 Wiley-Liss, Inc. [source]

Anxiety disorders and risk for suicide attempts: findings from the Baltimore Epidemiologic Catchment area follow-up study,

DEPRESSION AND ANXIETY, Issue 6 2008
James M. Bolton M.D.
Abstract Our objective was to determine whether the presence of an anxiety disorder was a risk factor for future suicide attempts. Data were drawn from the 13-year follow-up Baltimore Epidemiological Catchment Area survey (n=1,920). Multiple logistic regression analysis was used to determine the association between baseline anxiety disorders (social phobia, simple phobia, obsessive-compulsive disorder, panic attacks, or agoraphobia) and subsequent onset suicide attempts. The presence of one or more anxiety disorders at baseline was significantly associated with subsequent onset suicide attempts (adjusted odds ratio 2.20, 95% confidence interval 1.04,4.64) after controlling for sociodemographic variables and all baseline mental disorders assessed in the survey. These findings suggest that anxiety disorders are independent risk factors for suicide attempts, and underscore the importance of anxiety disorders as a serious public health problem.

A double-blind study of the efficacy of venlafaxine extended-release, paroxetine, and placebo in the treatment of panic disorder

DEPRESSION AND ANXIETY, Issue 1 2007
Mark H. Pollack M.D.
Abstract To date, no large-scale, controlled trial comparing a serotonin,norepinephrine reuptake inhibitor and selective serotonin reuptake inhibitor with placebo for the treatment of panic disorder has been reported. This double-blind study compares the efficacy of venlafaxine extended-release (ER) and paroxetine with placebo. A total of 664 nondepressed adult outpatients who met DSM-IV criteria for panic disorder (with or without agoraphobia) were randomly assigned to 12 weeks of treatment with placebo or fixed-dose venlafaxine ER (75,mg/day or 150,mg/day), or paroxetine 40,mg/day. The primary measure was the percentage of patients free from full-symptom panic attacks, assessed with the Panic and Anticipatory Anxiety Scale (PAAS). Secondary measures included the Panic Disorder Severity Scale, Clinical Global Impressions,Severity (CGI-S) and ,Improvement (CGI-I) scales; response (CGI-I rating of very much improved or much improved), remission (CGI-S rating of not at all ill or borderline ill and no PAAS full-symptom panic attacks); and measures of depression, anxiety, phobic fear and avoidance, anticipatory anxiety, functioning, and quality of life. Intent-to-treat, last observation carried forward analysis showed that mean improvement on most measures was greater with venlafaxine ER or paroxetine than with placebo. No significant differences were observed between active treatment groups. Panic-free rates at end point with active treatment ranged from 54% to 61%, compared with 35% for placebo. Approximately 75% of patients given active treatment were responders, and nearly 45% achieved remission. The placebo response rate was slightly above 55%, with remission near 25%. Adverse events were mild or moderate and similar between active treatment groups. Venlafaxine ER and paroxetine were effective and well tolerated in the treatment of panic disorder.

Panic and suicidal ideation and suicide attempts: results from the National Comorbidity Survey

DEPRESSION AND ANXIETY, Issue 3 2006
M.P.H., Renee D. Goodwin Ph.D.
Abstract Our objective was to determine the association between panic attacks (PAs) and panic disorder (PD), and suicidal ideation (SI) and suicide attempts (SAs) in a nationally representative sample of adults in the community. Data were drawn from the National Comorbidity Survey (n=5,877), a representative household sample of adults ages 15,54 in the United States. Multiple logistic regression analyses were used to examine the relationship between current and lifetime PA and PD and SI and SA, adjusting for differences in demographic characteristics, comorbid mental disorders (major depression, alcohol dependence, and substance dependence), childhood trauma (physical and sexual abuse), and number of lifetime mental disorders. Past-year and lifetime PA and PD were associated with increased SI (both past year and lifetime), and persisted after adjusting for comorbidity and early trauma. Associations between PA and SA were no longer statistically significant after adjusting for comorbidity. Past-year and lifetime PD were associated with lifetime SA, but these associations were no longer statistically significant after adjusting for comorbidity. Past-year and lifetime PD were associated with past-year SA, and this association persisted after adjusting for demographics, comorbidity, and number of lifetime mental disorders. These findings are consistent with previous results, and further help to clarify the relationships between panic and suicide behavior by identifying potential methodological reasons for inconsistencies in results from previous studies.

Batelaan NM, Smit F, de Graaf R, van Balkom AJLM, Vollebergh WAM, Beekman ATF. Identifying target groups for the prevention of anxiety disorders in the general population. Objective:, To avert the public health consequences of anxiety disorders, prevention of their onset and recurrence is necessary. Recent studies have shown that prevention is effective. To maximize the health gain and minimize the effort, preventive strategies should focus on high-risk groups. Method:, Using data from a large prospective national survey, high-risk groups were selected for i) the prevention of first ever (n = 4437) and ii) either first-ever or recurrent incident anxiety disorders (n = 4886). Indices used were: exposure rate, odds ratio, population attributable fraction and number needed to be treated. Risk indicators included sociodemographic, psychological and illness-related factors. Results:, Recognition of a few patient characteristics enables efficient identification of high-risk groups: (subthreshold) panic attacks; an affective disorder; a history of depressed mood; a prior anxiety disorder; chronic somatic illnesses and low mastery. Conclusion:, Preventive efforts should be undertaken in the selected high-risk groups. [source]

Ring chromosome 20 syndrome with intractable epilepsy

DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 5 2005
Asude Alpman MD
Ring chromosome 20 (r[20]) syndrome is characterized by mild to moderate learning disability*, behavioural disorders, epilepsy, and various dysmorphic features. Although still considered rare, r(20) syndrome is being increasingly diagnosed. More than 30 cases have been described in the literature since 1976. Here we report an additional case of a 14-year-old male with r(20). He had moderate to severe learning disability and epileptic seizures manifesting at about 18 months of age. During the 13 years' follow-up period he showed intractable epileptic seizures, behavioural disorders, and mild dysmorphological features including microcephaly, strabismus, micrognathia, down-slanting eyelids, and ear abnormalities. Frequent episodes of atypical absence or non-convulsive status associated with electroencephalogram changes were seen in follow-up. He was treated with several classical and new antiepileptic drugs, including intravenous immunoglobulin, corticotropin, and vagal nerve stimulation, with unsuccessful control of seizures. Finally, surgical treatment (corpus callosotomy) was performed at the age of 13 years; severity of tonic seizures was diminished, but frequency was unchanged. Although his behavioural problems, e.g. hyperactivity, were mild in early childhood they became more severe when he was 11 years old. Aggressiveness, compulsiveness with self-injury, and panic attacks developed at the age of 13 years, and were more pronounced after callosotomy. This case report provides the first description of deterioration in psychological situation in patients with r(20) intractable epilepsy. The patient was diagnosed with r(20) syndrome after 13 years of clinical follow-up. Karyotype analysis should, therefore, be performed in every patient with intractable epilepsy of unknown aetiology.

The efficacy of reboxetine in the treatment-refractory patients with panic disorder: an open label study

HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 7 2002
P. N. Dannon
Abstract Background and Objective Selective serotonin reuptake inhibitors (SSRIs) are currently the first-line treatment for panic disorder, although up to 30% of patients either do not respond to SSRIs or withdraw due to adverse events. Reboxetine, a selective norepinephrine reuptake inhibitor (selective NRI), is effective in treating depression and may alleviate depression-related anxiety. This study aimed to investigate the efficacy of reboxetine in the treatment of patients with panic disorder who did not respond to SSRIs. Method In this 6-week, open-label study, 29 adult outpatients with panic disorder who had previously failed to respond to SSRI treatment received reboxetine 2,mg/day, titrated to a maximum of 8,mg/day over the first 10 days. Efficacy was assessed using the Panic Self-Questionnaire (PSQ), the Hamilton Rating Scale for Anxiety (HAM-A), the 17-item Hamilton Rating Scale for Depression (HRSD) and the Global Assessment of Functioning (GAF) Scale. Results The 24 patients who completed the study responded well to reboxetine treatment. Significant improvement (p,<,0.001) was observed in the number of daily panic attacks, and on the scales measuring anxiety, depression and functioning. Reboxetine was generally well tolerated. Five patients withdrew due to adverse events. Conclusions Reboxetine appears to be effective in the treatment of SSRI-refractory panic disorder patients and warrants further clinical investigation.

Life-time history of suicide attempts and coronary artery disease in a community-dwelling elderly population

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 2 2006
S. Artero
Abstract Background Numerous studies have observed a strong relationship between coronary artery disease (CAD) and psychiatric disorder; notably depression, anxiety and panic attacks. No study has, however, explored the question of whether persons suffering from CAD might also be at high risk of suicide attempts. Objective The aim of the present study is to examine the relationship between CAD within a general population cohort and life-time history of psychiatric disorder and suicidal behaviour. Method A representative sample of 1843 non-institutionalized persons over 65, drawn at random from the electoral roll, was given a standardized neurological and psychiatric examination based on DSM-IV criteria. The clinical examination also included an electrocardiogram (ECG) and a questionnaire relating to life-time medical history. Cardiac events were validated by the general practitioner. Results Within this general population sample the prevalence of suicide attempts was 3.9%. A significant positive association was observed between life-time prevalence of CAD and suicide attempts (p,<,0.04). Suicide attempts were associated with major depression (p,<,0.001) co-morbid anxiety and depression (p,<,0.001) but not anxiety alone (p,=,0.16). A logistic regression analysis showed that the relationship between suicide attempts and CAD persists after adjustment for depression and anxiety. Conclusion CAD is associated with suicidal behaviour independently of depression, however, longitudinal studies are required to clarify the direction of causality and to integrate genetic, biological, environmental and psychological factors into an aetiological model.

Paroxysmal Hypertension: The Role of Stress and Psychological Factors

JOURNAL OF CLINICAL HYPERTENSION, Issue 7 2008
DPhil, Thomas G. Pickering MD
This paper reviews the limited literature on paroxysmal hypertension. A case report describes the clinical picture frequently seen in specialty hypertension practice, a patient with paroxysmal or intermittent hypertension who proves not to have a pheochromocytoma. The variety of diagnostic labels given to these patients is reviewed, including pseudopheochromocytoma, panic attacks, and hyperventilation syndrome. The clinical features, pathology, diagnosis, and treatment of these syndromes are outlined. It is proposed that successful management of these patients may be best achieved by collaborative care between a hypertension specialist and a psychiatrist or clinical psychologist with expertise in cognitive-behavioral panic management, stress-reduction techniques including controlled breathing, and treating health anxiety. The use of drugs effective for treatment of panic disorder can also be helpful in managing these patients. [source]

Decision-making needs of patients with depression: a descriptive study

JOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 4 2008
D. STACEY rn mscn phd
The study's purpose was to explore the decision-making needs of patients considering treatment options for their depression. Semi-structured interviews were guided by the Ottawa Decision Support Framework. Of 94 participants, 67 were uncertain about their decision. Common decisions identified were whether or not to take medications, attend support groups, undergo electroconvulsive therapy, and location of care. Those feeling certain were more likely to have made a decision (RR 1.37; 95% CI: 1.05, 1.78). However, 40 patients who had ,made a decision' in the recent past were uncertain about their decision. Compared with those who were certain, the uncertain group felt less informed (2.65 vs. 1.64; P < 0.001), less supported (2.63 vs. 1.88; P < 0.001) and less clear about how they valued the benefits and risks of options (2.57 vs. 1.69; P < 0.001). Other influential factors included concerns about confidentiality, distress from depression, embarrassment, panic attacks and lack of energy. Few patients wanted to defer decision making to their physician (n = 8) or family (n = 1). To support decision making, participants identified the need for: discussions with their psychiatrist, nurse or family doctor; access to printed information; and information provided by health professionals and health societies.

A randomized controlled trial of cognitive-behavior therapy for Cambodian refugees with treatment-resistant PTSD and panic attacks: A cross-over design

JOURNAL OF TRAUMATIC STRESS, Issue 6 2005
Devon E. Hinton
We examined the therapeutic efficacy of a culturally adapted cognitive-behavior therapy for Cambodian refugees with treatment-resistant posttraumatic stress disorder (PTSD) and comordid panic attacks. We used a cross-over design, with 20 patients in the initial treatment (IT) condition and 20 in delayed treatment (DT). Repeated measures MANOVA, Group & times; Time ANOVAs, and planned contrasts indicated significantly greater improvement in the IT condition, with large effect sizes (Cohen's d) for all outcome measures: Anxiety Sensitivity Index (d = 3.78), Clinician-Administered PTSD Scale (d = 2.17), and Symptom Checklist 90-R subscales (d = 2.77). Likewise, the severity of (culturally related) neck-focused and orthostasis-cued panic attacks, including flashbacks associated with these subtypes, improved across treatment. [source]

Incidence of psychiatric side effects during pegylated interferon- , retreatment in nonresponder hepatitis C virus-infected patients

LIVER INTERNATIONAL, Issue 8 2007
Lucas C. Quarantini
Abstract Objective: Evaluate the incidence of mental disorders using pegylated interferon plus ribavirin retreatment in nonresponder hepatitis C virus-infected patients. Method: The Mini-International Neuropsychiatric Interview (MINI) was used to evaluate 30 hepatitis C virus-infected interferon-nonresponder patients at baseline and following 4, 12 and 24 weeks of pegylated interferon retreatment. Results: During the pegylated interferon/ribavirin retreatment, 5(16.6%) patients developed psychiatric side effects: 3(10%) were diagnosed with major depressive disorder, 1(3.3%) had a brief psychotic disorder and 1(3.3%) presented with panic attacks. Conclusion: This is the first prospective study evaluating the incidence of neuropsychiatric side effects during interferon retreatment of hepatitis C virus-infected patients, suggesting that the risk of acquiring serious psychiatric symptoms during retreatment with interferon-, (IFN-,) may not be higher than during the first antiviral therapy. This finding challenges the hypothesis that during a second treatment with IFN-,, patients with hepatitis C may be at greater risk for neuropsychiatric side effects than naïve patients. [source]

Age at onset in bipolar affective disorders: a review

BIPOLAR DISORDERS, Issue 2 2005
Marion Leboyer
Bipolar affective disorder (BPAD) is a multifactorial disorder with various clinical presentations. Etiologic heterogeneity may partly underlie the phenotypic heterogeneity. Efforts to dissect BPAD have been based on the course of the disorders (BP I versus BP II or rapid cycling), cormorbidity pattern (panic attacks, suicide attempts, addiction or hyperactivity), differences between the sexes, and clinical pattern (cycloid and puerperal psychosis). The present article provides a comprehensive review of the existing data, showing that age at onset (AAO) identifies homogeneous sub-groups of patients with BPAD. Recent work has demonstrated the existence of three , early, intermediate and late , onset bipolar sub-groups based on AAO, following Kendell's criteria for validity (The American Journal of Psychiatry 2003; 160: 999). We will also show how these distinctions may be of use in the search for genetic vulnerability factors and other pathogenic influences. Following Kendell's criteria, we show that AAO of bipolar disorders has been tested with most of the available strategies for establishing the validity of clinical syndromes. We also present data from genetic epidemiologic studies in bipolar disorder, showing that AAO sub-groups may reduce the underlying genetic heterogeneity. No accurate AAO thresholds to define valid sub-groups have been identified precisely. Until recently, studies defined early- and late-onset as corresponding to early or mid-adulthood, not taking into account juvenile-onset bipolar disorder. A recently proposed theoretical model with three AAO sub-groups (onset age 17, 27 and 46) is discussed. [source]
