RESUMO
OBJECTIVE: Bipolar disorder (BP) frequently co-occurs with other psychiatric disorders. We examine whether course of anxiety disorders (ANX), attention deficit hyperactivity disorder (ADHD), disruptive behavior disorders (DBD), and substance use disorders (SUD) influence likelihood of recovery and recurrence of depression and mania in BP youth. METHOD: Weekly ratings of psychiatric disorder intensity were obtained from 413 participants of the Course and Outcome of BP Youth project, followed for an average of 7.75 years. Multiple-event Cox proportional hazards regression analyses examined worsening of comorbid disorders as predictors of mood episode recovery and recurrence. RESULTS: Increased severity in ANX and SUD predicted longer time to recovery and less time to next depressive episode, and less time to next manic episode. Multivariate models with ANX and SUD found that significant effects of ANX remained, but SUD only predicted longer time to depression recovery. Increased severity of ADHD and DBD predicted shorter time to recurrence for depressive and manic episodes. CONCLUSION: There are significant time-varying relationships between the course of comorbid disorders and episodicity of depression and mania in BP youth. Worsening of comorbid conditions may present as a precursor to mood episode recurrence or warn of mood episode protraction.

In an attempt to prospectively validate the existence of supersensitivity psychosis (SSP), five schizophrenic patients meeting Chouinard's criteria for SSP and five non-SSP schizophrenic controls had neuroleptic treatment withdrawn for 2 weeks under double-blind conditions. The sudden worsening of psychotic symptoms and tardive dyskinesia postulated in the SSP group was not observed on the Brief Psychiatric Rating Scale, the Clinical Global Impressions scale, and the Abbreviated Dyskinesia Rating Scale. In conclusion, the authors' pilot data do not seem to support the existence of SSP.

Chouinard has suggested that a significant number of schizophrenic outpatients may rapidly relapse after discontinuing or abruptly reducing antipsychotic drugs, and he has hypothesized that this relapse reflects a supersensitivity psychosis related to mesolimbic postsynaptic dopamine supersensitivity caused by drug therapy. Using Chouinard's criteria, the authors found 12 probable but no definitive cases of this syndrome while conducting a chart review of 265 hospitalized schizophrenic patients. Six of the 12 patients were subsequently rediagnosed as schizoaffective. Four patients had tardive dyskinesia, but this condition did not worsen after the drug dosage was decreased. Although supersensitivity psychosis was not common among this population, further study of the syndrome is needed to determine if neuroleptics are causing a subgroup of patients to relapse early or if the early relapses are a manifestation of the natural course of illness in these patients.
