Drugs that block ________ receptors often lessen the positive symptoms of schizophrenia.

Question

Quizplus · Accepted Answer

The positive symptoms of schizophrenia, such as hallucinations and delusions, are thought to be caused by an overactivity of dopamine in certain areas of the brain. Drugs that block dopamine receptors, such as antipsychotics, are commonly used to treat these symptoms. Norepinephrine and serotonin are also neurotransmitters, but they are not as strongly linked to the symptoms of schizophrenia as dopamine. Acetylcholine is more associated with cognitive function and memory, and drugs that affect acetylcholine are more commonly used to treat Alzheimer's disease.
