SLU analysis finds hyperlink between nervousness issues, benzodiazepine publicity and dementia in seniors

Analysis from Saint Louis College Faculty of Medication finds that amongst sufferers 65 and older, a analysis of tension was considerably related to an elevated danger of dementia analysis, and benzodiazepine publicity was related to a 28% elevated danger of dementia. Nevertheless, when benzodiazepines had been prescribed to sufferers with an nervousness dysfunction, there was no important affiliation between these drugs and incident dementia.

The research, “Nervousness Issues, Benzodiazepine Prescription and Incident Dementia,” was revealed on-line July 28 within the Journal of the American Geriatrics Society.

Jay A. Brieler, M.D., affiliate professor of household and group medication at SLU, is the paper’s first creator. Jeffrey Scherrer, Ph.D., professor of household and group medication and a member of the AHEAD Institute, is the senior creator.

Benzodiazepine prescriptions for older sufferers is controversial. Their use has been related to brief time period cognitive impairment, falls, and fractures. Per Dr. Brieler,

As a clinician who incessantly treats sufferers with nervousness issues, latest research suggesting benzodiazepine use might contribute to dementia had been very regarding to me. I had the belief that if a benzodiazepine was used and unwanted effects occurred, merely stopping the remedy would treatment the issue over time.

The tough subject with these research is that nervousness itself can also be related to dementia. It was nonetheless unclear from the literature whether or not the illness or the therapy was the perpetrator. Primarily based on our work, it seems that each are enjoying an element, nevertheless it stays unsure how the 2 work together with one another.”

We overcame that impediment by utilizing the VDW and experience obtainable within the AHEAD Institute.”
