Imagine a scenario where one in four seniors with dementia is given medications that could actually harm them. It’s not just a hypothetical—it’s happening right now. Despite clear warnings from medical guidelines, a shocking number of older adults with dementia are still being prescribed brain-altering drugs linked to serious side effects like falls, confusion, and even hospitalization. But here’s where it gets even more concerning: these prescriptions are often given without a clear medical reason, putting vulnerable patients at unnecessary risk.
New research, set to be published on January 12 in the prestigious journal JAMA, reveals that while overall prescriptions for these risky medications dropped from 20% to 16% over nine years among Medicare beneficiaries, the rate remains alarmingly high for those with dementia. And this is the part most people miss: even though progress has been made, over two-thirds of patients receiving these drugs in 2021 had no documented clinical justification. This suggests widespread inappropriate prescribing, which could be doing more harm than good.
Dr. John N. Mafi, a leading expert from UCLA, highlights the urgency of the issue: ‘Compared to patients with normal cognition, older adults with cognitive impairment are not only prescribed these medications more often but also face a higher risk of adverse effects. This is a critical area where we can—and must—improve care for millions of seniors.’
The study, which analyzed data from the Health and Retirement Study linked to Medicare claims, focused on central nervous system (CNS)-active medications prescribed to older adults with varying levels of cognitive health. These drugs, including antidepressants with strong anticholinergic properties, antipsychotics, barbiturates, benzodiazepines, and sleep aids, are particularly risky for those with dementia. For instance, while only 17% of seniors with normal cognition received these medications, the rate jumped to nearly 22% for those with cognitive impairment and a staggering 25% for those with dementia.
Here’s a breakdown of the prescription trends by medication class:
- Benzodiazepines: Declined from 11.4% to 9.1%
- Sleep medications (nonbenzodiazepine hypnotics): Dropped sharply from 7.4% to 2.9%
- Antipsychotics: Increased from 2.6% to 3.6%
- Anticholinergic antidepressants: Remained steady at 2.6%
- Barbiturates: Slightly decreased from 0.4% to 0.3%
While there’s been progress in reducing inappropriate prescriptions (down from 15.7% to 11.4%), the study also found that clinically justified prescriptions fell slightly from 6% to 5.5%. This raises a critical question: Are we doing enough to prioritize patient safety over convenience?
The findings aren’t without limitations. Missing data from Medicare Advantage plans and a focus on prescribing prevalence rather than cumulative exposure could skew the results. Still, the message is clear: we need better oversight and alternatives to these risky medications.
Dr. Annie Yang, who led the study, emphasizes the importance of patient-physician collaboration: ‘While these medications may be necessary in some cases, it’s crucial for patients and their caregivers to work closely with doctors to ensure they’re truly needed. When they’re not, exploring safer alternatives or tapering off the medication could be life-changing.’
But here’s the controversial part: Some argue that these medications, despite their risks, are sometimes the only option for managing severe symptoms in dementia patients. Is it fair to withhold them entirely, or should we focus on stricter monitoring instead?

This study, funded by the National Institutes of Health/National Institute on Aging, was conducted by a team of researchers from UCLA, Yale University, RAND, and the University of Michigan. It’s a call to action for healthcare providers, policymakers, and families alike to reevaluate how we care for our aging population. After all, every senior deserves safe, effective treatment—not a prescription that could do more harm than good.
