Some people dismiss memory problems as a normal part of aging, but what most people do not know is that memory loss can be caused by prescription drugs and medications. A Place for Mom expert and geriatrician Leslie Kernisan, MD, provides some guidance about the types of brain-slowing medication to avoid if you’re worried about memory loss for yourself or your aging loved one.
While people may think that not much can be done to improve memory in seniors, Dr. Kernisan discusses that there are actually steps that can be taken to determine whether memory problems like Alzheimer’s or dementia can be helped, or even fixed. In fact, the brain has the ability to grow new brain cells and reshape their connections throughout life. Dr. Kernisan notes:
“There is a lot that can and should be done, if you notice memory or thinking changes in yourself or in another older adult. You should do it because it ends up making a difference for brain health and quality of life. And what especially troubles me is that most of these older adults — and their families — have no idea that many have been linked to developing dementia, or to worsening of dementia symptoms. Every older adult and family should know how to optimize brain function, and avoiding problem medications, or at least using them judiciously and in the lowest doses necessary, is key to this.”
Identifying medications that make brain function worse should be at the top of the list of things to review. According to Dr. Kernisan, many seniors are taking over-the-counter or prescription medications that dampen brain functioning, which is often not necessary.
Dr. Kernisan shares some of the most commonly used drugs that you should be on the lookout for if you are worried about memory problems:
These medications are prescribed to help with sleep or anxiety problems, but they are also habit-forming and have been associated with developing dementia.
Commonly prescribed benzodiazepines include:

*Note that it can be dangerous to stop benzodiazepines suddenly. These drugs should always be tapered, under medical supervision.
Alternatives to Consider:
Dr. Kernisan notes that there is no easy and fast alternative for insomnia, as just about all sedatives dampen brain function. Many people can learn to sleep without drugs, but it usually takes a dedicated effort over weeks, or even months. This may involve cognitive-behavioral therapy, as well as increased exercise and other lifestyle changes.
For anxiety, there is also no easy replacement. However, there are some drug options that affect brain function less, such as SSRIs (e.g. sertraline and citalopram, brand names Zoloft and Celexa). Cognitive behavioral therapy and mindfulness therapy also helps, if sustained.
Even if it’s not possible to entirely stop a benzodiazepine, tapering to a lower dose will likely help brain function in the short-term.
Other Risks in Seniors:
Things to Keep in Mind:
If a person does develop dementia, it becomes much harder to stop these drugs. So it’s much better to find non-benzo ways to deal with anxiety and insomnia sooner, rather than later.
Also known as the “z-drugs,” these commonly used sleeping aides have been shown to impair both thinking and balance:
While studies have linked these drugs to dementia, their direct relationship with sleeping makes the cause-effect relationship a little murky, according to Dr. Kernisan. See section one for the alternatives to consider for these drugs.
Things to Keep in Mind:
These drugs worsen balance and increase fall risk.
The anticholinergics include most of the over-the-counter sleeping medicines, as well as many of the prescription drugs. Since this group blocks the neurotransmitter, acetylcholine, they have the opposite effect of an Alzheimer’s drug like Donepezil (Aricept) — a cholinesterase inhibitor, that works against the enzyme that breaks down acetylcholine. In fact, according to Dr. Kernisan, a 2015 study found that greater use of anticholinergics was linked to a higher chance of developing Alzheimer’s.
Since drugs vary in strength, it’s important to determine whether your medicine, or you family member’s medicine, is one of the drugs that has ‘high’ anticholinergic activity. Here is a list that classifies high and low anticholinergic activity. Dr. Kernisan’s Nextvenue article, “7 Common Drugs That Are Toxic for Your Brain” is a good place to find out which drugs put you or your loved one most at risk. Here are some very common ones to be aware of:
Alternatives to Consider:
Checking with a doctor or pharmacist for non-drug alternatives is always a smart way to go as they may not be available unless you ask.
Things to Keep in Mind:
In addition to affecting thinking, these drugs can affect balance. Dry mouth, dry eyes and constipation can also be side affects.
These medications are usually prescribed to help manage difficult behaviors caused by Alzheimer’s and dementia, and sometimes mental illnesses, such as schizophrenia. A New York Times story recently discussed how these drugs are often inappropriately prescribed and are even linked to a higher chance of death.
Common antipsychotics and mood-stabilizers include:
Alternatives to Consider:
Dr. Kernisan that it’s important to assess what’s causing the problem and try and manage treatment without drugs, if possible. For example, behavioral approaches have shown to be an effective treatment, in many instances. There is scientific evidence suggesting that the following may help:
Things to Keep in Mind:
Antipsychotics have been associated with falls, and there is an increased risk of death.

It is important to remember that good brain function is crucial for maintaining independence and quality of life. If you are worried that your loved one is at risk for altered brain function as a result of medications, it’s important to consult a doctor or pharmacist. In many cases, the medication can be dropped or changed; or behavioral therapies may be the right choice for you. But never stop medications without talking to a health professional first as you don’t want to compromise your loved one’s care.
