Psychotic disorders in Asian Americans and DSM-5.

The DSM-5 lists 13 psychotic disorders and introduces modest but significant changes in their diagnosis. Asian Americans bring unique issues to the assessment, diagnosis and treatment of these disorders. They may exhibit greater prevalence of culturally influenced psychosis-like experiences that may or may not constitute a pathological condition such as psychosis risk syndrome or attenuated psychosis. Acute psychotic disorders with good prognosis may be more prevalent in Asians and may sometimes be misdiagnosed as schizophrenia or schizoaffective disorder. Catatonic disorders are also more prevalent in Asians, and are likely to receive more appropriate labeling with DSM-5. The expanded cultural formulation in DSM-5 is a progressive step but its benefits might be limited by lack of culturally trained clinicians and/or limited time for assessment. There is a dearth of systematic data on psychotic disorders in Asian Americans and it is hoped that the DSM-5 will stimulate this much needed research.
