An upcoming paper adds to concerns that anticholinergic drugs can affect cognition in older people. Anticholinergic drugs are often used to treat Parkinson’s, as well as other problems in older people, like incontinence.
Over the years, I’ve taken all three of the anticholinergics, including Artane (aka trihex), and Akineton (no longer available in the US). I’m still taking benztropine, although at a low dosage, due to the common side effect of constipation. My head is clear these days.
However, Akineton definitely affected my thinking. It was manageable, but it made me weird. I’m glad to be off of it.
