Doctors warn against common over-the-counter allergy medicine taken by tens of millions... 'risk of substantial reactions'

"A landmark 2015 study in JAMA Internal Medicine by American researchers followed more than 3,400 older adults for seven years.

The study found that frequent users of diphenhydramine and other antihistamines faced a 54 percent higher risk of developing dementia and a 63 percent higher risk of Alzheimer's disease compared to non-users"

@LoriQuaid These are the old sedative antihistamines and the reason they are problematic is that they cross the blood brain barrier and are also anticholinergics. Modern anti-histamines are larger molecules that are less able or unable to cross be blood brain barrier and thus do not have the same negative impact on cognition.
