There’s been a great deal of research into how psychosis affects the brain and how changes in the brain can trigger symptoms of psychosis.
Researchers believe dopamine plays an important role in psychosis.
Dopamine is a neurotransmitter, 1 of many chemicals the brain uses to transmit information from 1 brain cell to another. It’s associated with how we feel whether something is significant, important, or interesting.
Disruption to these important brain functions may explain the symptoms of psychosis.
Evidence for the role of dopamine in psychosis comes from several sources, including brain scans and the fact medicines known to reduce the effects of dopamine in the brain also reduce the symptoms of psychosis.
