Antipsychotic medication use leads to measurable changes in brain volume
Is it true that Antipsychotic medication use leads to measurable changes in brain volume?
Yes. Multiple longitudinal neuroimaging studies indicate that antipsychotic medication use is associated with measurable structural brain changes, including regional volume increases in the basal ganglia and progressive, dose-dependent cortical and subcortical alterations.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The retrieved papers include multiple longitudinal neuroimaging investigations demonstrating structural brain changes associated with antipsychotic medication exposure. Specifically, papers [2], [3], and [8] all report measurable anatomical alterations—such as striatal volume changes, ventricular enlargement, and cortical thickness reductions—linked to antipsychotic treatment. No papers provided refute the claim.
