Risperidone in the treatment of behavioural and psychological symptoms of dementia in patients diagnosed with vascular or mixed-type dementia.

Objective Studies have found that the atypical antipsychotic drug, risperidone, reduces non-cognitive symptoms, such as aggression, agitation, and psychosis, in patients with Alzheimer's disease. This study assessed whether these effects extend to patients with vascular or mixed-type dementia. Methods In this multicentre, open-label, prospective study, 75 elderly patients with vascular or mixed-type dementia and concomitant behavioural and psychological symptoms were treated with risperidone for up to 6 months.
