Some alarming headlines say “8 drugs that cause dementia.” In reality, doctors say certain medications may increase the risk of memory problems or dementia when used long-term, especially in older adults. The biggest concern is a group called anticholinergic drugs, which affect the brain chemical acetylcholine, important for memory and learning. (WebMD)
Below are examples of drug types often mentioned in studies.
8 Types of Drugs Linked to Higher Dementia Risk
1. Strong Anticholinergic Antidepressants
Examples: amitriptyline, dosulepin, paroxetine.
Some research links long-term use to increased dementia risk in older adults. (alzheimers.org.uk)
2. Bladder Control Medications
Examples: oxybutynin, tolterodine, solifenacin used for overactive bladder.
These anticholinergic drugs have shown associations with dementia risk. (alzheimers.org.uk)
3. First-Generation Antihistamines (Allergy Drugs)
Examples: diphenhydramine (common sleep/allergy medicine).
These can strongly block acetylcholine and may affect memory with long-term use. (Harvard Health)
4. Antipsychotic Medications
Used for schizophrenia or severe mental illness.
Some studies suggest long-term use may contribute to cognitive decline. (Medical News Today)
5. Parkinson’s Disease Anticholinergic Drugs
Examples: procyclidine, trihexyphenidyl.
These can affect brain signaling related to memory. (alzheimers.org.uk)
6. Certain Anti-Nausea or Vertigo Drugs
Examples: promethazine, prochlorperazine.
These medications also have anticholinergic effects. (Medical News Today)
7. Some Anti-Seizure Medications
Examples: carbamazepine and similar drugs in some studies. (Medical News Today)
8. Long-Term Sedatives (Benzodiazepines)
Examples: diazepam or alprazolam.
Some research suggests long-term use may be linked with higher Alzheimer’s risk, though results are mixed. (The Times of India)
✅ Important:
- These drugs do not automatically cause dementia.
- Risk often appears with high doses or long-term use, especially in people over 65.
- Doctors usually prescribe them because the benefits outweigh the risks for many patients.
⚠️ Never stop a prescribed medication suddenly. Always talk to a doctor first.
