Medications Found to Cause Long Term Cognitive Impairment of Aging Brain
Posted Jul 13 2010 2:59pm
Drugs commonly taken for a variety of common medical conditions including insomnia, allergies, or incontinence negatively affect the brain causing long term cognitive impairment in older African-Americans, according to a study appearing in the July 13, 2010 print issue of Neurology, the medical journal of the American Academy of Neurology.
These drugs, called anticholinergics, block acetylcholine, a nervous system neurotransmitter, and are widely-used medical therapies. They are sold over the counter under various brand names such as Benadryl®, Dramamine®, Excedrin PM®, Nytol®, Sominex®, Tylenol PM®, and Unisom®. Other anticholinergic drugs, such as Paxil®, Detrol®, Demerol® and Elavil® are available only by prescription. Older adults most commonly use drugs with anticholinergic effects as sleep aids and to relieve bladder leakage problems.
Researchers from Indiana University School of Medicine, the Regenstrief Institute and Wishard Health Services conducted a six-year observational study, evaluating 1,652 Indianapolis area African-Americans over the age of 70 who had normal cognitive function when the study began. In addition to monitoring cognition, the investigators tracked all over-the-counter and prescription medications taken by study participants.
