Increased Mortality in Geriatric Patients with Dementia-related Psychosis
- Geriatric patients with dementia-related psychosis treated with antipsychotic agents are at an increased risk of death.a e l m o
- Analyses of 17 placebo-controlled trials in geriatric patients mainly receiving atypical antipsychotic agents revealed an approximate 1.6- to 1.7-fold increase in mortality compared with that in patients receiving placebo.a l m
- Most fatalities appeared to result from cardiovascular-related events (e.g., heart failure, sudden death) or infections (mostly pneumonia).a m
- Observational studies suggest that conventional or first-generation antipsychotic agents also may increase mortality in such patients.a e l
- Antipsychotic agents, including trifluoperazine, are not approved for the treatment of dementia-related psychosis.a l m
