Researchers at Indiana University and at University of Kent and Kings College London in the U.K. recently combined the results of nine studies on whether cholinesterase inhibitors improve psychological symptoms in Alzheimer’s patients. Cholinesterase inhibitors (Aricept, Exelon and Razadyne) are drugs prescribed to treat the cognitive symptoms of the disease.
Based on their “meta-analysis” of the combined results, the researchers concluded that these medicines appeared to reduce psychological symptoms in people with mild to moderate Alzheimer’s. However, the positive effects were small enough that they might not make a difference for patients or caregivers.
The analysis did not show a positive effect for people with severe Alzheimer’s.
