Anticholinergic drugs, commonly prescribed to treat a range of disorders, from Parkinson's disease to bladder conditions, may increase dementia risks. The increased risk was linked to anticholinergic antidepressants, antipsychotics, bladder control, epilepsy and Parkinson's disease medications. There were no increased risks associated with other types of anticholinergics, such as gastrointestinal drugs or antihistamines.
