Study links incontinence drugs with memory problems

CHICAGO (AP) - Commonly used incontinence drugs may cause memory problems in some older people, a study has found. "Our message is to be careful when using these medicines," said U.S. Navy neurologist Dr. Jack Tsao, who led the study. "It may be better to use diapers and be able to think clearly than the other way around."

Urinary incontinence sometimes can be resolved with non-drug treatments, he added, so patients should ask about alternatives. Exercises, biofeedback and keeping to a schedule of bathroom breaks work for many.

U.S. sales of prescription drugs to treat urinary problems topped $3 billion in 2007, according to IMS Health, which tracks drug sales. Bladder control trouble affects about one in 10 people age 65 and older, according to the National Institute on Aging, which helped fund the study. Women are more likely to be affected than men. Causes include nerve damage, loss of muscle tone or, in men, enlarged prostate.
