The claim that “7 medications cause severe dementia and profound brain damage” is misleading. Some medicines can increase the risk of confusion, delirium, memory problems, falls, or cognitive impairment, particularly in older adults, but that is not the same as proven permanent brain damage or dementia.
Seven medication groups that deserve particular attention in older adults include:
-
Benzodiazepines — diazepam, lorazepam, alprazolam, clonazepam. They can cause sedation and cognitive impairment and carry important dependence and withdrawal risks. U.S. Food and Drug Administration+1
-
First-generation antihistamines — diphenhydramine and chlorpheniramine, for example. Their anticholinergic effects can impair cognition.
-
Certain tricyclic antidepressants — such as amitriptyline, because of their anticholinergic effects.
-
Some bladder anticholinergics — particularly oxybutynin, which can affect cognition.
-
Z-drugs — zolpidem, zaleplon, and eszopiclone; these can cause CNS effects and are generally discouraged in many older adults. AGS Journals+1
-
Antipsychotics — particularly in older people with dementia, where they carry significant risks and should be used only when the potential benefits justify them.
-
Barbiturates and other strongly sedating medicines — these can produce substantial CNS depression and cognitive effects and are generally avoided in older adults when safer alternatives exist. AGS Journals+1
The important part
Don’t stop any of these medications suddenly. This is especially important with benzodiazepines: abrupt discontinuation can cause severe withdrawal, including seizures, and the FDA recommends gradual, individualized tapering when discontinuation is appropriate. U.S. Food and Drug Administration
If you’re concerned about a particular person’s medicines, give me the medication names and doses (and, if relevant, their age). I can identify which ones may contribute to memory problems or confusion and explain what should be discussed with their doctor.
