Document Summary

The new scheme of sub-dividing schizophrenia categories is based on the predominance of negative versus positive symptoms. Negative symptoms involves behavioral deficits, such as flattened emotions, social withdrawal, apathy, impaired attention, and poverty of speech. Positive symptoms involve behavioral excesses or peculiarities, such as hallucinations, delusions, bizarre behavior, and wild flights of ideas. A predominance of positive symptoms is associated with better adjustment prior to the onset of schizophrenia and greater responsiveness to treatment. Schizophrenic disorders usually emerge during adolescence or early adulthood and only infrequently after age 45. Emergence of schizophrenia may be sudden or gradual. Research suggests that perhaps as many as one-half of schizophrenic people experience a reasonable recovery. Gender is associated with the course and outcome of schizophrenia. Hereditary factors play a role in the development of schizophrenic disorders. Schizophrenic disorders appear to be accompanied by changes in activity of one or more neurotransmitters in the brain.
