Low doses of brexpiprazole (0.5-2 mg per day) have been tried to treat dementia-related psychosis/ agitation and Parkinson’s disease psychosis. We report a 71-year-old patient with a diagnosis of probable dementia with Lewy body (DLB) whose psychotic symptoms benefit from a higher dose of brexpiprazole (4 mg per day) without adverse effects. Though more studies were needed to confirm the safety and efficacy of brexpiprazole in the treatment of DLB, this case suggests that brexpiprazole is a potential treatment choice and it is safe even at the maximum daily dose (i.e., 4 mg per day).
