In one study, they found that anti-cholinergic agents shows an increased risk of dementia. In the study, certain anti-depressants and urologic agents were found to correlate more with the risk of dementia including dosulepine, duloxetine and amitriptyline for the anti-depressants and tolteridine and oxybutinin for the urologic agents (1).
There are thoughts that there is a risk of dementia even 2 decades after the exposure. Certain anti-Parkinson’s agents were found to possible correlate with dementia. Anti-cholinergic agents have consistently been associated with problems with short-term memory.
