Mayo Clinic Rochester study reveals more apt to develop mild cognitive impairment
Mild cognitive impairment the nervous system disorder in which thinking abilities are reduced, the onset which occurs usually before developed dementia.
A new study now reveals the opposite of what many studies in the past had shown that women are at a higher risk for dementia than their male counterparts.
Mild cognitive impairment is more than those old age memory glitches seniors have from time to time.
MCI for short, include things such as forgetting things more often, losing train of thought or thread of conversation and showing increasingly poor judgment. Those with MCI have a increased risk for developing Alzheimer’s disease but not always will develop into Alzheimer’s or a more severe form of dementia.
Researchers from the Mayo Clinic, Rochester, consisted of 1,450 people age rage 70 to 89 years and did not have dementia at the start of study. Over the three years of this study, participants had underwent mental testing every fifteen months and had been interviewed about their memory. By the end of the study 296 people had developed MCI.
Researchers had found that MCI was higher in men than women with the development of MCI being at 7.2% for men and 5.7% of women. Also found was that those who were not married and had less education were also more likely to develop MCI.
According to Dr. Rosebud Roberts, neurologist and lead author of study at the Mayo Clinic, Rochester, the reasons for the findings is not clear and risk factors may occur earlier and at a higher rate in men than in women. Dr. Roberts further noted women could still develop risk factors for MCI at an older age however, the effects may be more severe when they occur.
With MCI being a risk factor for dementia, many of the baby boomer generation are reaching this age according to Dr. Roberts noting that we must prevent or reduce the risk of MCI or the increased development of dementia will have a tremendous impact of healthcare costs in the elderly.
Dr. Roberts also notes that some of the strongest risk factors MCI are the same of heart disease especially diabetes, high blood pressure and obesity.
Dr. Sam Gandy, M.D., PhD, Mount Sinai chair in Alzheimer’s research at the Mount Sinai School of Medicine, New York City commented the findings were surprising. Also, noting the predominance of Alzheimer’s disease is greater in women mostly due to longevity. That’s why, “most people would have guessed equal incidence of MCI to be more in women.” Alzheimer’s disease is the most common cause of dementia in people aged 65 and older. “
Dr. Roberts stated that In the future, “increased efforts should be made to understand differences in risk factors for MCI in men and women and efforts to prevent or control these risk factors should be sex specific.”
Dr. William H. Thies, PhD, chief medical and scientific officer with the Alzheimer’s Association, noted that the medical community is not prepared to deal with the arrival of Alzheimer’s disease which is expected to occur in the next forty years. Dr. Thies predicts that cognitive condition will not see breakthrough treatments in the same way as other major diseases had without adequate investment in new research and treatment.
Noted by Dr. Thies was the fact Alzheimer’s receives a few hundred million a year. This is in comparison to around five to six billion a year for research investments in cancer, heart disease and AIDS.
This study is published in the January 25th issue of Neurology.
In 2010, a Mayo Clinic study had found that physical activity and computer usage just may help protect against mild cognitive impairment. The study reveals that combining both of these activities appears to be more beneficial in reducing cognitive impairment.
According to the study it was found that engaging in physical activity whether it is once a week or five times a week and engaging in mental activities particularly computer use appears to have a combination effect in protecting against mild cognitive impairment.
The World Health Organization recommends that older adults age 65 and older in general should have at least 150 minutes (2 ½ hours) of moderate intensity aerobic physical activity throughout the week or 75 minutes of vigorous-intensity aerobic throughout the week or an equal combination of both.
Moderate activities include brisk walking, water aerobics and ballroom dancing.
Vigorous intensity includes walking, jogging and aerobic dance.
