High-stress, which has already been blamed of causing numerous health problems from depression to high blood pressure, has now been charged on causing Alzheimer’s disease. According to scientists at Albert Einstein College of Medicine and Montefiore Health System, people with mild cognitive impairment (MCI) are at increased risk of developing Alzheimer’s disease. Researchers said there is huge link between high stress and type of memory decline that is often as a prelude of Alzheimer’s disease. They added that people with high stress are more likely to develop MCI and so the disease.
During the 3.6 year study, 71 out of 507 participants aged 70 and over from Bronx County, New York, were diagnosed with amnesiac mild cognitive impairment (aMCI). Researchers used standardized stress tests to measure the stress level of participants. In the study published in the Alzheimer Disease & Associated Disorders, researchers found 30% increased risk of developing Alzheimer’s condition in patients with high stress levels. Dr. Richard Lipton, senior author of the study and vice chair of neurology at Einstein and Montefiore, said the latest study provides strong evidence of the fact that high stress increases the possibility of developing aMCI in older people.
Keith Fargo, the Director of Scientific Programs and Outreach at the Alzheimer's Association, said “authors measured new cases of amnestic mild cognitive impairment (aMCI), a condition characterized by a decline in memory that is measurable and noticeable but not severe enough to disrupt basic activities of daily living”. According to the scientific literatures, there exist strong link between high stress levels and developing of Alzheimer’s disease. But, the fact is still unclear that whether the stress causes Alzheimer’s, whether the decline into Alzheimer’s disease is the cause of high stress levels of both the conditions are viable. The latest study only shows link between stress and Alzheimer’s disease and not explains reason whether stress or perceived stress causes aMCI.
People with high stress levels have been advised to do regular exercise, physical activity, meditation and yoga in order to relieve them of their condition.
