A popular anticholesterol drug cuts older adults' chances of developing dementia by more than half, according to a new review of 4.5 million medical records.
Earlier research offered a mixed picture of cholesterol-reducing statins and their ability to prevent Alzheimer's disease and other dementias. Researchers at Boston University and the Veterans Administration (VA) in Washington, D.C., suspected that the confusion may have arisen from the failure of those studies to sort out the effects of various statin medications.
Researchers from the two institutions reviewed the records of patients treated at VA hospitals from 2002 to 2005.
