Describe the evidence for dopamine's role in psychosis
Most anti-psychotic medications work by blocking dopamine in the brain The negative side effects of anti-psychotic drugs are similar to Parkinson’s (which is caused by insufficient dopamine) Drugs that treat Parkinson’s increase dopamine levels, which can cause psychosis Amphetamines (e.g. crystal meth) and related drugs that work on dopamine (e.g. cannabis, cocaine) can lead to psychosis
42
Describe the evidence for dopamine's role in psychosis
Many people with schizophrenia do not benefit from anti-psychotic medications that influence dopamine Anti-psychotic medications block dopamine quickly, but changes in symptoms are not seen for days or weeks Anti-psychotic medications are only somewhat helpful for negative symptoms Clozapine is an extremely effective medication for schizophrenia, but only acts weakly on dopamine
