Benzodiazepine Drugs Tied To Increased Risk of Dementia
New research suggests the practice of using benzodiazepines to treat psychiatric conditions should be abandoned as evidence suggests the drugs heighten the risk for dementia and death.
Benzodiazepines include branded prescription drugs like Valium, Ativan, Klonopin, and Xanax. This class of drug received FDA approval in the 1960s and was believed to be a safer alternative to barbiturates.
Despite new psychiatric protocols, some physicians continue to prescribe benzodiazepines as a primary treatment for insomnia, anxiety, post-traumatic stress disorder, obsessive compulsive disorder, and other ailments.
“Current research is extremely clear and physicians need to partner with their patients to move them into therapies, like antidepressants, that are proven to be safer and more effective,” said Helene Alphonso, DO, a board-certified psychiatrist and Director of Osteopathic Medical Education at North Texas University Health Science Center.
“Due to a shortage of mental health professionals in rural and underserved areas, we see primary care physicians using this class of drugs to give relief to their patients with psychiatric symptoms. While compassionate, it’s important to understand that a better long-term strategy is needed.”
Alphonso will review current treatment protocols, outpatient benzodiazepine detox strategies, and alternative anxiety treatments at OMED 15, to be held October 17-21 in Orlando. OMED is the annual medical education conference of the American Osteopathic Association.
A Canadian review of 9,000 patients found those who had taken a benzodiazepine for three months or less had about the same dementia risk as those who had never taken one. Taking the drug for three to six months raised the risk of developing Alzheimer’s disease by 32 percent, and taking it for more than six months boosted the risk by 84 percent. Similar results were found by French researchers studying more than 1,000 elderly patients.
Experts say the case for limiting the use of benzodiazepines is particularly compelling for patients 65 and older, who are more susceptible to falls, injuries, accidental overdose, and death when taking the drugs. The American Geriatric Society in 2012 labeled the drugs “inappropriate” for treating insomnia, agitation, or delirium because of those risks.
“It’s imperative to transition older patients because we’re seeing a very strong correlation between use of benzodiazepines and development of Alzheimer’s disease and other dementias. While correlation certainly isn’t causation, there’s ample reason to avoid this class of drugs as a first-line therapy,” Alphonso said.
