January 26, 2012 - Men are more at risk for mild cognitive impairment, a new study shows. The results were amazing, we refer to the investigators, because women generally have higher rates of dementia."We expect to see a similar proportion of mild cognitive impairment in men and women," said lead researcher Gemma Roberts, MBChB, of the Mayo Clinic in Rochester, Minnesota, Medscape Medical News.The results, published online January 25 in the journal Neurology, suggest that should determine the risk factors for memory loss by sex. Researchers wonder whether there could be even sex-specific strategies to reduce risk.

Epidemiological data from the Mayo Clinic study of aging "is of interest to one concerned with how changes brain function with age," noted Dr. Rockwood.Investigators studied the population-based cohort of potential Olmsted County, Minnesota. They assessed the population aged between 145,070 حتي 89 years at baseline and at regular intervals to assess the clinical dementia rating scale, health, neurological and neuropsychological.Examiners were blind to previous diagnoses and data that are reviewed at each evaluation to assess the situation according to the knowledge and dissemination standards.The researchers found that the incidence of mild cognitive impairment was prevalent in about 64 per 1000 more than 2 to 4 years. Were evaluated for the vast majority of people are at least 3 times.Cases of mild cognitive impairment (n = 296) *

* Data are number per 1000 patient years."The risk of mild cognitive impairment in men and women together was high in this age group of seniors," said Roberts. "This is worrying given that people are living longer, and mild cognitive impairment may have a significant impact on health care costs if they are not used to increase prevention efforts to reduce the risk."The incidence of mild cognitive weakness is also higher for people with less education than for those who continued their studies (42.6 versus 32.5). This was also the case for mild cognitive weakness nonamnestic - less education, and seemed to put people at a disadvantage in the knowledge later in life (20.3 versus 10.2)."This discovery was not clear from the occurrence of other investigations," noted Dr. Rockwood outside ", but he was not particularly in the prevalence estimates from the Mayo Clinic study."The researchers also found that among people newly diagnosed with mild memory loss, later was diagnosed 12% annually at least once with no cognitive impairment and returned to what appeared to return to the memory of sound. However, Roberts said the majority of people with mild cognitive impairment - about 88% per year - still have symptoms or dementia.The study was funded by the National Institutes of Health, the Robert Wood Johnson Foundation, the Robert H. Smith and Clarice program and Abigail van Buren Alzheimer's disease research, and project Epidemiology of Rochester. Dr. Roberts received research support from the National Institutes of Health and Abbott.
