[Acute Psychotic Disorders].

Acute psychotic disorders (APS) are characterized by an acute onset as well as a wide array of symptoms including affective, psychotic, and psychomotor symptoms. They occur independently of substance use or organic disorders. In most cases, patients recover fully and without residues within a short period of time. However, APS tend to show a relapsing course, and transitions into other psychiatric disorders (schizophrenia, bipolar disorder) may occur.
