Is bipolar II disorder misdiagnosed as major depressive disorder in children?

OBJECTIVES: To estimate the lifetime prevalence of bipolar II disorder in children and adolescents presenting with DSM-IV major depressive disorder (MDD). METHODS: Sixty-one consecutive subjects aged < or =18 years attending the outpatient services of the Child and Adolescent Psychiatric (CAP) services of the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore, India with a diagnosis of MDD were evaluated using the Missouri Assessment of Genetics Interview for children (MAGIC). Two psychiatrists, one of whom was a child psychiatrist diagnosed hypomania by consensus. RESULTS: Twelve children had a past episode of hypomania (20%), which was hitherto undiagnosed clinically. LIMITATIONS: We recruited subjects from a psychiatric hospital, thus limiting the generalizability of the finding. Sample size was relatively small and assessments were cross-sectional. CONCLUSIONS: : Our study shows that bipolar II disorder is often misdiagnosed as MDD in children. The study also highlights that the chance of diagnosing bipolarity is enhanced by using semi-structured interview in routine clinical practice.

A follow-up study of juvenile obsessive-compulsive disorder from India.

OBJECTIVE: To study the long-term course and outcome of juvenile obsessive-compulsive disorder (OCD). METHOD: Two to 9-year follow-up of largely self-referred, drug-naïve subjects (n = 58) by employing catch-up longitudinal design. RESULTS: The mean follow-up period was 5 years. Nearly three-fourth of the sample was adequately treated with medications. Only 21% of the subjects had clinical OCD at follow-up and 48% were in true remission (no OCD and not on treatment). Earlier age-at-onset was associated with better course and outcome. CONCLUSION: Juvenile OCD has favorable outcome. Our findings are applicable to psychiatric hospital settings in India and perhaps to the general psychiatric settings in the Western countries. Whether the better outcome in this sample is the result of differing clinical characteristics or because of true cross-cultural variation in the course needs further exploration. It is speculated that early onset OCD could be a subtype of juvenile OCD with better outcome.

A family study of juvenile obsessive-compulsive disorder.

OBJECTIVES: To determine whether juvenile obsessive-compulsive disorder (OCD) is familial and whether the rate of Tourette syndrome (TS) and tic disorders is higher among relatives of patients with OCD than among relatives of controls subjects. METHOD: We assessed first-degree relatives of 35 juvenile OCD probands (aged 16 years or less) and 34 matched, psychiatrically unaffected control subjects, using the Diagnostic Interview for Children and Adolescents-Revised (DICA-R) (unpublished), a Questionnaire for tic disorders, the Children's Version of Leyton's Obsessional Inventory (CV-LOI), and the Children's Version of the Yale-Brown Obsessive Compulsive Scale (CY-BOCS). Similarly, we assessed adult relatives, using the Schedule for Clinical Assessment in Neuropsychiatry (SCAN), Leyton's Obsessional Inventory (LOI), the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), and a Questionnaire for tic disorders. The diagnoses were determined by consensus, using DSM-III-R criteria. We calculated age-corrected morbid risk, using Weinberg's method. RESULTS: The morbid risk for OCD among the relatives of OCD probands was 4.96%, while none of the relatives of unaffected control subjects had OCD. We did not diagnose TS in any of the relatives of either OCD probands or control subjects. We diagnosed chronic motor tic disorders in only 1 of the relatives of OCD probands, while none of the relatives of control subjects had any tic disorder. CONCLUSION: Most juvenile cases of OCD are nonfamilial and unrelated to tic disorders, while only a few are familial. There is a need to re-examine the issue of familiality in cases of OCD, as well as its relation to TS, using larger community samples to better understand the hypotheses of familial transmission and comorbidity with tic disorders.

Comorbidity in juvenile obsessive-compulsive disorder: a report from India.

OBJECTIVE: Using minimal exclusion criteria, to assess systematically the psychiatric comorbidity in children and adolescents with obsessive-compulsive disorder (OCD) and compare the findings with those of previous studies. METHOD: Fifty-four children and adolescents who satisfied DSM-III-R criteria for OCD were assessed using a structured interview schedule, the Children's version of the Yale-Brown Obsessive Compulsive Scale (CY-BOCS), and the questionnaire for tic disorders. All 54 subjects were recruited from the Child and Adolescent Psychiatry (CAP) services of the National Institute of Mental Health and Neuro Sciences (NIMHANS), Bangalore, South India. Diagnoses were determined consensually after a review of all the available data. RESULTS: Comorbidity was found in 69% of the sample: 22% were diagnosed with disruptive disorders; 20% met criteria for mood disorders; 19% had anxiety disorders; and 17% had tic disorders. Only 1 subject had bipolar disorder, and none had psychosis. The rates for individual diagnoses--in particular, the rates for disruptive disorders, bipolar disorder, and psychosis--were considerably lower than those reported in previous studies. CONCLUSIONS: Patterns of comorbidity in this study differed from those previously reported. Novel patterns of comorbidity with disruptive disorders, bipolar disorder, and psychosis reported in a few recent studies were not replicated in this study. These differences are probably due to different ascertainment methods. Comorbidity needs to be assessed in large epidemiological samples before definite associations can be made between certain comorbid disorders and juvenile OCD.
