Question

Quizplus · Accepted Answer

Research has shown that some people's schizophrenia may result from abnormalities in the brain's receptor sites for dopamine, a neurotransmitter that is involved in regulating mood, motivation, and reward. High levels of dopamine activity in certain areas of the brain have been associated with psychotic symptoms like delusions and hallucinations. Medications used to treat schizophrenia work by blocking dopamine receptors to reduce the excess activity in the brain.
