Document Summary
16. 3 medical and biological treatments: healing the mind by physically altering the brain. Directly affecting the brain to cure psychological disorders has been an idea present for a very long time. Antipsychotic drugs: treat schizophrenia and related psychotic disorders. Before these drugs, people with schiz had to be kept in hospitals to protect them and other people from themselves. Psychopharmacology: the study of drug effects on psychological states and symptoms. Area between tegmentum (in the midbrain) and various subcortical structures. Dopamine hypothesis: suggests that schiz may be caused by excess dopamine in the synapse. Negative symptoms such as emotional numbing and social withdrawal may be related to dopamine underactivity. Antipsychotic medications do not relieve negative symptoms well. Affect both dopamine and serotonin systems (block both types of receptors) Increased serotonin activity = help with cognitive and perceptual disruptions and mood disturbances. Help with negative symptoms as well now! Older drugs = conventional or typical antipsychotics.
