Schizophrenia is a chronic, severe, and disabling brain disease.
The first signs of schizophrenia often appear as confusing, or even shocking, changes in behavior. Less obvious symptoms, such as social isolation or withdrawal, or unusual speech, thinking, or behavior, may precede, be seen along with, or follow the psychotic symptoms. A lot of complex brain chemistry is involved in understanding what is happening in schizophrenia and even though the brain imaging technologies available within the last ten years are providing a wealth of information, the brain is still basically an uncharted world.
