The purpose of this study is to collect and study the brain tissue of deceased individuals to learn more about the nervous system and mental disorders. Information gained from donated tissue may lead to better treatments and potential cures for nervous system and mental disorders.

This study will ask relatives of deceased individuals to donate the brains of their deceased relatives to allow further study of neurological and psychiatric disorders....

The knowledge of how affected tissue deviates from normal control tissue is an integral part of fully understanding a neurological or psychiatric disorder. The purpose of this protocol is to establish a coordinating program with the pathology departments of the Washington, D.C. and metropolitan area hospitals and local medical examiner's offices for the donation of brain tissue.

• INCLUSION CRITERIA:

Brain tissue is needed from individuals suffering from a variety of neuropsychiatric disorders, especially schizophrenia, but also anxiety disorders, suicide, bipolar disorder, depression, Tourette's Syndrome, drug addictions (PCP, cocaine, alcohol, heroin or the like) and any form of dementia. In addition, brains from normal individuals without a history of neuropsychiatric disease will be needed for controls.
