Comparative Study
The economic burden of schizophrenia in the United States in 2002.
This study quantifies excess annual costs associated with schizophrenia patients in the United States in 2002 from a societal perspective. ⋯ Schizophrenia is a debilitating illness resulting in significant costs. The indirect excess cost due to unemployment is the largest component of overall schizophrenia excess annual costs.

Hoarding may be an important symptom dimension in obsessive-compulsive disorder (OCD). Hoarding in OCD has been associated with poor insight, poorer response to selective serotonin reuptake inhibitors than other OCD symptom dimensions, and a distinctive psychobiological profile. The clinical and genetic correlates of hoarding in OCD therefore deserve additional investigation. ⋯ These data are consistent with the hypothesis that hoarding represents a unique symptom subtype in OCD with a distinctive clinical and psychobiological profile. Further work is needed to determine the psychobiological mechanisms responsible for hoarding and to replicate the genetic findings noted here.

Comparative Study
Impact of sleep-related complaints on depressive symptoms in patients with restless legs syndrome.
Restless legs syndrome (RLS) is a distressing sensorimotor disorder with a 5% to 10% prevalence in the United States and Western Europe. The nocturnal occurrence of symptoms often leads to severe sleep disturbances. RLS has been reported to be associated with depression and anxiety. The aim of the present study was to investigate the relationship between RLS symptom severity, sleep disturbances, and depressive symptoms. ⋯ RLS patients scored high on the somatic items of the BDI, particularly on those related to sleep disturbance, but not on the other items that mostly address cognitive symptoms. Our results indicate that RLS might be associated with some features of depression but not with the full spectrum of a depressive disorder. The relationship between the 2 disorders should be investigated in further studies.

Multicenter Study Comparative Study Clinical Trial
Symptom clusters as predictors of late response to antidepressant treatment.
While there is some indication from studies in the acute phase of antidepressant treatment that there are differences in the timing of improvement in symptoms, relatively little work has explored the patterns of change for specific symptom clusters and the predictability of these changes to signal eventual response during the acute phase of treatment. This article investigates the use of clusters of symptoms on the 17-item Hamilton Rating Scale for Depression (HAM-D-17) to define the pattern of late response versus nonresponse to antidepressant medication. ⋯ Monitoring changes in symptom clusters from the HAM-D-17 during this crucial early stage (first 4 weeks) can be used to distinguish late responders (after week 4) from nonresponders. Successful identification of nonresponders based on symptom cluster change in the first 4 weeks would facilitate a shortening of an ineffective treatment trial and allow for necessary changes in treatment strategy, helping physicians more closely follow treatment guidelines.

Comparative Study Clinical Trial
Behavioral treatment of obesity in patients taking antipsychotic medications.
Antipsychotic medications are associated with weight gain and metabolic dysregulation, yet little is known about the management of obesity among individuals with severe and persistent mental illness. Thus we sought to evaluate the potential utility of a behavioral weight control program for this population. ⋯ Behavioral weight control is a promising approach to the treatment of obesity among outpatients taking antipsychotic medications, but longer and more robust interventions are needed.
