Describe two biological therapies for schizophrenia and then evaluate each in terms of effectiveness (8 + 16 marks): One biological therapy is the use of typical anti-psychotic drugs‚ such as Chlorpromazine. The main aim of this drug is to treat schizophrenia by reducing the amount of dopamine in the brain.
