a significant disturbance of the mind. To diagnose Schizophrenia, Psychiatrists look for two or more of the following symptoms: delusions, hallucinations, disorganized speech, very disorganized behavior, catatonic behavior (no movement at all), little emotion (compared to normal for the person), trouble speaking, or reduced "goal-directed behavior" (trouble getting things done). Because other problems can cause these symptoms, psychiatrists look for the problems to last six months or more before they diagnose schizophrenia. Schizophrenia can usually be at least partly controlled with drugs, but there is not usually a cure.
The essential features of this disorder are the presence of characteristic psychotic symptoms during the active phase of the illness and functioning below the highest level previously achieved, and a duration of at least six months. At some phase of illness, schizophrenia always involves delusions, hallucinations, or certain characteristic disturbances in affect and the form of thought.
