⚠️ Important: Some medications have been associated with an increased risk of cognitive decline or dementia-like symptoms, especially with long-term use. However, association isn’t the same as proven causation—many studies show links but not definitive cause-and-effect. Always talk with your doctor before changing or stopping any medication. (Healthline)
Here are 8 types of drugs that research has linked to a higher risk of dementia or serious cognitive problems when used long term:
🧠 1. Anticholinergic Medications
These block the neurotransmitter acetylcholine, important for memory and thinking.
Commonly linked to higher dementia risk in older adults. (Healthline)
Examples include:
• Some antidepressants (older tricyclics)
• Antipsychotics
• Antiparkinson’s drugs
• Bladder control medicines
• Antiepileptic drugs
These are often prescribed for depression, urinary issues, epilepsy, and movement disorders. (Medical News Today)
💤 2. Benzodiazepines
Used for anxiety, insomnia or seizures (e.g., Valium, Xanax).
Long-term use has been linked with memory problems and increased dementia risk, especially in older people. (Healthline)
💊 3. Proton Pump Inhibitors (PPIs)
These are acid-reflux drugs like omeprazole and esomeprazole.
Some studies suggest prolonged use may be linked with higher dementia risk, possibly via nutrient effects like vitamin B12 deficiency. (The Times of India)
💉 4. Opioids
Strong painkillers (e.g., morphine, oxycodone).
Chronic use—especially in older adults—has been associated with cognitive decline and elevated dementia risk. (Healthline)
📉 5. Corticosteroids
Steroids like prednisone can cause reversible dementia-like cognitive issues with prolonged use, and may affect memory and brain structure when used long-term. (ALOT Health)
🔄 6. Tricyclic Antidepressants
Some older antidepressants (like amitriptyline, nortriptyline) have strong anticholinergic effects that can impact memory and cognition over time. (The Times of India)
💊 7. Antipsychotic Drugs
Used in psychiatric disorders and sometimes in dementia symptom management.
They are associated with serious side effects and an increased risk of cognitive decline in older adults. (Healthline)
🧠 8. Antiepileptic / Other Nervous System Drugs
Some seizure or nerve-pain medications have been linked in observational studies to a higher risk of cognitive impairment and dementia. (Medical News Today)
🧠 What This Doesn’t Mean
- It doesn’t prove these drugs directly cause dementia—many studies are observational and could be influenced by underlying conditions or age.
- Many of these medications are essential for treating serious medical issues, so don’t stop them without medical guidance. (Cleveland Clinic)
✅ If you’re concerned about dementia risk:
✔ Talk with your doctor or pharmacist about long-term medications and alternatives
✔ Ask if any drugs could be reduced or switched safely
✔ Discuss lifestyle factors (sleep, exercise, diet) that support brain health
