What are biological explanations?Show answer
The dopamine hypothesis is the central biological explanation.
What are treatments?Show answer
Biological treatment uses antipsychotic drugs. Typical antipsychotics (chlorpromazine) are dopamine antagonists that block receptors and reduce positive symptoms but carry serious side effects, notably tardive dyskinesia (involuntary movements). Atypical antipsychotics (clozapine, risperidone) act on dopamine and serotonin, target negative symptoms better and have fewer movement side effects, though clozapine risks agranulocytosis (a fall in white blood cells).
