Antidepressant shows early promise in treating agitation and psychotic symptoms of dementia
Date:9/9/2007

Toronto, ONT Researchers have found surprising evidence that an antidepressant (citalopram) may perform as well as a commonly-prescribed antipsychotic (risperidone) in the alleviation of severe agitation and psychotic symptoms of dementia. Researchers also found that the antidepressant was associated with significantly lower adverse side effects.

The study, published in the online American Journal of Geriatric Psychiatry (in advance of the November 2007 issue), is believed to be the first head-to-head comparison of an SSRI (selective serotonin reuptake inhibitor) with one of the more commonly prescribed second generation antipsychotics in older, non-depressed patients.

The findings are exciting because they raise the possibility of a new direction in drug treatment for psychotic disorders related to dementia in the elderly. However, the researchers caution that more studies are needed to replicate their early findings and that second generation antipsychotics continue to be a first-line pharmacological treatment, despite growing scientific evidence that they can be associated with serious side effects, including death.

We are encouraged by this early data, but we need to learn more in further trials that include a placebo group before we can say with confidence that antidepressants are an effective and safe treatment for agitation and psychosis in patients suffering from dementia, says lead investigator Dr. Bruce Pollock, who teamed up with colleague Dr. Benoit Mulsant to conduct the study.

Both scientists are internationally recognized for their research in geriatric psychopharmacology the study of the effects of drugs on mood, behavior and cognition in late life. They are now with leading Toronto-based research institutes Dr. Pollock with the Rotman Research Institute at Baycrest and the Geriatric Mental Health Program at the Centre for Addiction and Mental Health (CAMH), and Dr. Mulsant with the Geriatric Mental Health Prog
