If you’re fact-checking the headline “8 Drugs That Cause Serious Dementia,” it needs an important correction: there isn’t a proven list of eight medications that simply cause dementia. Some medications can cause temporary confusion or cognitive impairment, and prolonged exposure to certain drugs—particularly those with strong anticholinergic effects—has been associated with a higher risk of dementia in observational studies. That doesn’t prove that the medication itself caused the dementia.

Medication groups worth reviewing in older adults
Strong anticholinergics — examples include oxybutynin and some older antihistamines. These can cause confusion and memory problems, and long-term exposure to some anticholinergic drugs has been associated with dementia.

BMJ
Tricyclic antidepressants — such as amitriptyline, which has substantial anticholinergic activity.
Certain bladder medications — particularly anticholinergic drugs such as oxybutynin. FDA reviewers have specifically highlighted concerns about CNS effects in older people.
F
FDA Access Data
Benzodiazepines — including diazepam, lorazepam, and alprazolam. They can cause sedation and cognitive impairment and carry additional risks of dependence, withdrawal, and falls.
U
U.S. Food and Drug Administration
Sedative-hypnotics — such as zolpidem, which can cause drowsiness, dizziness, and cognitive impairment, particularly in older adults.
F
FDA Access Data
Certain antiparkinson medications with anticholinergic effects — these can be particularly problematic for cognition in older adults.
Some antipsychotic medications — these can worsen confusion and have serious risks in people who already have dementia; they should generally be used cautiously and for specific indications.
Medications with a high overall anticholinergic burden — sometimes the problem isn’t one drug but the combined effect of several medications with anticholinergic properties.

The important distinction
A medication causing confusion, sedation, or delirium is not the same thing as causing irreversible dementia. Some drug-related cognitive problems can improve when the offending medication is reduced or discontinued under medical supervision.
If an older adult develops new confusion or memory problems, a medication review is worthwhile because medications can be a potentially reversible contributor.
Don’t abruptly stop benzodiazepines, antidepressants, sleeping pills, or other regularly prescribed medications. Some require gradual dose reduction to avoid dangerous withdrawal.

If you give me the 8 medication names from the article, I can go through them one by one and tell you which have strong evidence, which have weak evidence, and which claims are simply clickbait.
