In April 2005, the US Food and Drug Administration (FDA) issued an advisory and subsequent black box warning regarding the risks of atypical anti psychotic use among elderly patients with dementia. The FDA advisory was associated with decreases in the use of atypical antipsychotics, especially among elderly patients with dementia. Subsequent research reports confirmed the mortality risks associated with the use of both conventional and atypical antipsychotics to treat patients with dementia. Consequently, in 2008 the FDA issued although a black box warning for classical neuroleptics. Data on treatment efficacies are strongest for atypical antipsychotics. Adverse effects in patients with dementia include an increased risk of mortality and cerebrovascular events, as well as metabolic effects, extrapyramidal symptoms, falls, cognitive worsening, cardiac arrhythmia, and pneumonia. Conventional antipsychotics may pose an even greater safety risk. No clear efficacy evidence exists to support the use of alternative psychotropic classes (e.g. antidepressants, anticonvulsants).
