Anticholinergic drugs block the action of acetylcholine which stimulates muscle contractions. They treat things like gastrointestinal problems, overactive bladder, respiratory disorders, insomnia, depression and allergies. Benadryl and Tylenol PM are commonly used anticholinergic that are sold over-the-counter. In the study, the drugs were found to have a cumulative effect that may not be reversible. You can view a list of anticholinergic drugs available by prescription on the Mayo Clinic Site.
