Common drugs linked to memory problems, new study finds

A recent study from the University of California, San Diego, has found that a widely used group of medications, known as anticholinergic drugs, may be linked to memory problems in older adults.

These medications are often prescribed for various health issues, including high blood pressure, allergies, Parkinson’s disease, and bladder problems. Some of these drugs can be purchased over the counter, while others require a prescription.

The research team, led by Lisa Delano-Wood, studied 688 older adults with an average age of 74. At the start of the study, none of the participants showed signs of memory loss or cognitive issues. The researchers wanted to understand if regular use of anticholinergic drugs could affect memory and thinking skills over time.

Participants were asked if they were taking any anticholinergic medications regularly—defined as at least once a week for more than six months.

These types of drugs work by blocking a chemical in the brain called acetylcholine, which is involved in memory and learning. While anticholinergic drugs are helpful for treating various conditions, blocking this chemical might also affect brain function.

To track changes in memory and thinking skills, the researchers tested the participants every year for up to 10 years. They found that about one-third of the participants were taking at least one anticholinergic drug during the study period.

The results were concerning. People who regularly used these medications had a 47% higher chance of developing memory problems compared to those who did not use them. Memory problems are often an early warning sign of more serious cognitive conditions like dementia or Alzheimer’s disease.

The study also found that the risks were even greater for people who already had signs of Alzheimer’s or a genetic risk for the disease.

Those with Alzheimer’s biomarkers were four times more likely to develop memory problems if they were taking anticholinergic drugs. Meanwhile, those with a genetic risk for Alzheimer’s were 2.5 times more likely to experience memory decline.

These findings suggest that cutting back on the use of anticholinergic medications might help prevent memory loss, especially in people who are at higher risk for Alzheimer’s disease.

However, it is important to remember that you should never stop or change your medication without talking to your healthcare provider first. Suddenly stopping some medications can cause serious health problems, and it’s crucial to get proper guidance before making any changes.

If you are taking medication for high blood pressure, allergies, or other conditions, it’s a good idea to be aware of the potential side effects.

There may be alternative treatments or lifestyle changes that can help manage these conditions without the risks associated with anticholinergic drugs. For example, certain dietary choices like adding beetroot to your diet have been shown to support healthy blood pressure levels.

The findings of this important study were published in the journal Neurology. This research highlights the importance of understanding how common medications can affect memory and brain health, especially as we age. It also underscores the need for doctors and patients to discuss the risks and benefits of any long-term medication use.

Staying informed about the latest scientific research can help you make better decisions about your health. If you are concerned about the medications you are taking, talk to your healthcare provider.

They can help you understand your options and suggest alternatives if necessary. Managing your health with awareness and knowledge can help you stay healthier and protect your memory as you age.
