Washington: No evidence was found in a review of published research to prove that drugs, herbal products or vitamin supplements help prevent cognitive decline in healthy older adults.The review, conducted at St. Michael`s Hospital, found some evidence that mental exercises, such as computerized memory training programs, might help."This review provides some evidence to help clinicians and their patients address what strategies might prevent cognitive decline," Dr. Raza Naqvi, a University of Toronto resident and lead author of the review, said.The issue is of particular importance given that mild cognitive impairment affects 10 to 25 percent of people over age 70.Mild cognitive impairment is characterized by reduced memory, judgment, and decision-making skills compared to someone of a similar age, but not enough to interfere with daily activities.
