Study Details

Brief summary:

To test the feasibility of studying effects of smoking cessation with varenicline on antipsychotic drug-induced neurological side effects, we propose a 12 week pilot study of smoking cessation treatment with varenicline in 10 schizophrenia or schizoaffective disorder patients who are actively smoking and have pre-existing TD while receiving stable doses of antipsychotics. Subjects will be followed after a 2 week baseline period to assess changes in smoking status and neurological symptoms using standardized rating scales. The aim is to examine clinically significant effects on antipsychotic-induced neurological side effects that may warrant further investigation.
