The path toward mitigating medication-related dementia risk involves proactive steps focusing on medication management, diet, and lifestyle changes.
1. Medication Review and Deprescribing
This is the most crucial step. Doctors, and often more effectively, pharmacists, should regularly check and adjust medications, especially for older patients, to ensure they are only taking what is truly necessary.
- Deprescribing: This clinical practice involves systematically reducing or stopping medications that are no longer beneficial or may be causing harm. It requires a doctor’s guidance, but patients should initiate the conversation, asking: “Can we safely reduce or stop this medication?”
- Pharmacist Consultation: Pharmacists are experts in drug interactions. Schedule a full medication review with your local pharmacist to identify potential conflicts and unnecessary prescriptions.
2. Alternative Therapies
Whenever possible, look into non-drug treatments for common issues. Chronic conditions often driving polypharmacy—like insomnia, anxiety, and long-term pain—respond very well to non-pharmacological interventions.
- Insomnia and Anxiety: Instead of relying on benzodiazepines or strong anticholinergic sleep aids, consider Cognitive Behavioral Therapy for Insomnia (CBT-I), stress management techniques, and practicing strict sleep hygiene.
- Chronic Pain: Physical therapy, exercise, massage, and acupuncture can often manage long-term pain with zero cognitive side effects.
3. A Healthier Brain Diet
One key thing that is often overlooked when discussing medication risk is the foundational role of diet. Eating poorly and consuming highly processed foods creates the underlying inflammation and vascular damage that makes the brain more vulnerable to the negative effects of drugs.
Research shows that a diet rich in whole, unprocessed foods can help keep your brain working well and lower your risk of dementia by:
- Boosting BDNF: Brain-Derived Neurotrophic Factor (BDNF) is a protein that promotes the growth of new neurons and synapses. Diets rich in omega-$3$s and polyphenols (found in the Mediterranean diet) increase BDNF.
- Reducing Chronic Inflammation: Diets high in refined sugar and poor fats fuel systemic inflammation, while diets focused on fruits, vegetables, and healthy fats (like the Mediterranean diet or a simple Ketogenic approach) help quell it.
- Supporting Mitochondria: A clean, nutrient-dense diet provides the brain’s powerhouses (mitochondria) with the clean fuel they need to function optimally.
My strongest suggestion is to educate yourself deeply on this topic. Read books, consult registered dietitians, and become proficient in practicing these healthy eating plans.
4. Education and Awareness
Patients and their caregivers must become educated consumers of healthcare. Do not stay silent. You need to know the brain risks of the medicines you are taking and be encouraged to look for alternatives.
- Ask Direct Questions: “Does this drug have anticholinergic effects?” or “How might this interact with the other 5 medications I am taking?”
- Maintain a Master List: Keep an up-to-date list of every single drug, supplement, and over-the-counter medicine you take and bring it to every doctor’s appointment.
Sadly, today, it is rare to find an older person who is not taking multiple medications. Those who do live exceptionally healthy lives, maintain a normal weight, sleep well, and remain functionally healthy often credit their success to a long life of avoiding unnecessary pharmaceuticals and prioritizing whole, clean foods. The data suggests that many who died much earlier or became seriously sick often spent decades gradually deteriorating by taking a flood of chemical substances while consuming a highly harmful diet—and then, seemingly suddenly, dementia and other serious diseases finally manifest. The time to take action is now.
