Dr Zain Hasan, a Los Angeles-based anesthetist, told his 635,000 followers on TikTok that there are at least five drugs linked to the condition — including some antidepressants, painkillers and allergy meds.

The first drug he included in his warning was antihistamine medication used to help ease the symptoms of allergies, as well as anticholinergics, also used to treat allergies.

These medications, some of which are available over the counter, are used to treat hayfever, eczema, hives, and conjunctivitis, which causes red and itchy eyes.

However, Dr Hasan said long-term use has been linked to dementia.
