Treating schizophrenia
Traditional drug treatments for schizophrenia block receptors for the neurotransmitter dopamine in the brain. They are effective in relieving hallucinations and delusions, but have little effect on other symptoms: lack of motivation, tiredness and depression. Newer drugs, which act at several receptor sites, including those for serotonin and dopamine, seem to be effective in treating these symptoms as well, and have fewer unpleasant side-effects.
