Schizophrenia is the disruption of cognition and emotion affecting the human’s language, thought, perception, affect, and sense of self. Symptoms include hearing voices inside your head, hallucinations, delusions, and depression. No single symptom is definitive for diagnosis; rather, the diagnosis encompasses a pattern of signs and symptoms with social changes and personality changes. Symptoms are typically divided into positive and negative symptoms because of their impact on diagnosis and treatment. Positive symptoms are those that appear to reflect an excess or distortion of normal functions. The diagnosis of schizophrenia, according to DSM-IV, requires at least 1-month duration of two or more positive symptoms, unless hallucinations or delusions are especially bizarre, which would be a sign of the disorder. Negative symptoms are those that appear to reflect a loss of normal functions. Loss of usual interests or pleasures (anhedonia); disturbances of sleep and eating; dysphoric mood (depressed, anxious, irritable, or angry mood); and difficulty concentrating or focusing attention, are also symptoms oh the disorder.
