A common class of drugs that doctors prescribe for a number of conditions — from bladder problems to Parkinson’s disease and depression — may increase a person’s risk of dementia, a large new study concludes.

New research by scientists from the University of Nottingham in the United Kingdom has analyzed the link between a certain class of drugs and the risk of dementia.

The drugs in question, called anticholinergics, work by inhibiting a chemical messenger called acetylcholine.

Their effect is to help relax or contract muscles, and doctors can prescribe them to help treat bladder conditions, gastrointestinal problems, and some of the symptoms of Parkinson’s disease.

In their new study, which looked at data from tens of thousands of participants, the researchers concluded that anticholinergics may increase a person’s risk of developing dementia.
