If you’re fact-checking the claim “7 medications that cause severe dementia and profound brain damage,” that wording is misleading. There are medications that can impair cognition, cause delirium, or are associated with increased dementia risk, particularly in older adults, but it is not accurate to say that seven medications simply cause severe dementia and permanent brain damage.

7 medication groups that deserve particular attention
Diphenhydramine and other first-generation antihistamines — strong anticholinergic effects can cause confusion and delirium; cumulative anticholinergic exposure is associated with increased dementia risk.

Oxybutynin and other bladder anticholinergics — can produce cognitive adverse effects, with oxybutynin having particularly strong evidence for this concern.

Amitriptyline and other strongly anticholinergic antidepressants — can cause sedation, confusion, and other cognitive effects, especially in older adults.

Benzodiazepines such as diazepam, lorazepam, and alprazolam — increase the risk of cognitive impairment and delirium in older adults and can cause dependence.

Z-drugs such as zolpidem — can cause adverse CNS effects, confusion, and increased fall risk in older adults.

Antipsychotics — can worsen cognitive decline in people with dementia and are associated with increased stroke and mortality risk in that population. They nevertheless have legitimate uses for certain psychiatric and neurological conditions.

Certain medications with strong anticholinergic activity used in combination — the problem can be the total anticholinergic burden, rather than one particular drug. Combining multiple such medicines increases the risk of cognitive decline, delirium, and falls.

The crucial distinction
Temporary medication-induced confusion isn’t the same thing as dementia. Some cognitive effects can improve after the offending medication is reduced or discontinued under appropriate medical supervision.
And don’t abruptly stop medications such as benzodiazepines or sleeping medicines. Withdrawal can itself be dangerous, and medication changes should generally be discussed with a doctor or pharmacist.
If you give me the seven specific drug names from the post you’re looking at, I can separate them into well-supported concern, possible association, and outright misinformation.
