Although an exact definition of schizophrenia still evades medical researchers, the evidence indicates more and more strongly that schizophrenia is a severe disturbance of the brain's functioning. There are billions of nerve cells in the brain. Each nerve cell has branches that transmit and receive messages from other nerve cells. The branches release chemicals, called neurotransmitters, which carry the messages from the end of one nerve branch to the cell body of another. In the brain afflicted with schizophrenia, something goes wrong in this communication system.
