Common Drugs May Raise Your Risk of Dementia




(Newser)
                                        

                                        A new study in a peer-reviewed journal suggests that a type of drug is prescribed to treat depression, epilepsy, Parkinson's, and other ailments raises the risk of dementia. 50% greater odds of developing dementia, according to the study in JAMA Internal Medicine. No significant risk was seen with weaker anticholinergics, such as those used as antihistamine (Benadryl) or for gastrointestinal disorders, reports WebMD. The study-based data from more than 284,000 people age 55 and older between 2004 and 201

6 in the UK is observational, meaning it's not the drug cause.
                                    

"The study is authoritative," says Carol Carol, author of the study, Carol Coupland of the University of Nottingham, via CNN. Researchers already knew that anticholinergics can cause short-term side effects such as confusion, but this study takes a longer view. Anticholinergics help relax and contract muscles by blocking the chemical acetylcholine, explains WebMD. Those with the strongest link to dementia were antidepressants, bladder antimuscarinic drugs, Parkinson's drugs, and epilepsy drugs. No antihistamines, skeletal muscle relaxants, gastrointestinal antispasmodics, antiarrhythmics, or antimuscarinic bronchodilators. (A new form of dementia was just discovered.)
