A Double-Blind Randomized Placebo-Controlled Withdrawal Trial Comparing Memantine and Antipsychotics for the Long-Term Treatment of Function and Neuropsychiatric Symptoms in People With Alzheimer's Disease (MAIN-AD)

The results did indicate some benefits for antipsychotic medications in reducing the relapse of neuropsychiatric symptoms, but this must be balanced against increased mortality risk.
