Some commonly used medications have been linked in studies to a higher risk of cognitive decline or dementia, especially when used long-term or in older adults. This doesn’t mean the drugs always cause dementia, but research suggests they may increase the risk or worsen memory problems in certain people. Dementia
Below are 8 types of drugs experts often warn about.
1. Anticholinergic Drugs
These medications block acetylcholine, a brain chemical important for memory and learning. Long-term use (3+ years) has been linked to up to ~50% higher dementia risk in some studies.
Examples:
-
Oxybutynin
-
Tolterodine
-
Solifenacin
-
Procyclidine
Often used for:
-
Overactive bladder
-
Parkinson’s symptoms
-
Motion sickness
2. Benzodiazepines (Anti-Anxiety/Sedatives)
These drugs affect the brain’s central nervous system and may impair memory with long-term use.
Examples:
-
Diazepam
-
Lorazepam
-
Alprazolam
Use longer than a few months has been associated with increased dementia risk and cognitive impairment.
3. Sleeping Pills (“Z-drugs”)
Common sleep medications can affect brain activity and memory.
Examples:
-
Zolpidem
-
Zaleplon
-
Eszopiclone
These drugs are considered potentially inappropriate for people with cognitive problems.
4. Certain Antidepressants
Some older antidepressants, especially tricyclic types, have strong anticholinergic effects.
Examples:
-
Amitriptyline
-
Dosulepin
-
Paroxetine
These have been linked with increased dementia risk in several studies.
5. Antipsychotic Medications
Used to treat schizophrenia or severe behavioral disorders.
Examples:
-
Olanzapine
-
Quetiapine
-
Chlorpromazine
These medications may worsen confusion and cognitive decline in older adults.
6. Anti-Seizure / Antiepileptic Drugs
Some medications used for seizures or nerve pain have been associated with higher dementia risk.
Examples:
-
Carbamazepine
-
Sodium valproate
-
Phenytoin
These drugs have shown links to dementia in large studies.
7. Proton Pump Inhibitors (Acid-Reflux Drugs)
Used for heartburn and stomach acid problems.
Examples:
-
Omeprazole
-
Esomeprazole
Some studies suggest a possible connection with dementia, though evidence is still debated.
8. Gabapentin (Nerve Pain Drug)
A recent study found that frequent prescriptions of gabapentin were linked with 29% higher dementia risk and increased mild cognitive impairment.
✅ Important:
-
These medications do not automatically cause dementia.
-
The risk usually appears with long-term or high-dose use, especially in older adults.
-
Doctors often prescribe them because their benefits outweigh risks for many patients.
⚠️ Never stop a medication without consulting a doctor.
