According to the American Heart Association / American Stroke Association for the Study, published in Stroke («Stroke") - Journal of the American Heart Association, atherosclerosis, which causes heart disease, can also cause senile vascular cognitive impairment.The symptoms of cognitive impairment, also known as dementia, is the difficulty with the processes of thinking, reasoning and remembering.It can be caused by disease, Alzheimer's disease, or both diseases simultaneously, as well as other causes.
Atherosclerosis - is accumulation of plaque in the arteries, which is exacerbated by high blood pressure and cholesterol levels, smoking and other risk factors.When due to atherosclerosis is sharply limited or completely blocked blood flow to the brain, there is a cerebrovascular disorder (cerebrovascular accident), which may cause vascular cognitive impairment.
Alzheimer - is a progressive disorder of the brain, which damages and destroys brain cells."We found that cerebrovascular disorders and Alzh
risk of dementia increases with age and affects about 30 percent of people aged 80 years.According to the authors of the statement, each year in the United States spend more than $ 40 000 per patient with dementia.Gorelik said that the reduction in risk factors for heart disease and stroke with lifestyle changes and medication can prevent or slow the development of dementia in some people.Physical activity, healthy diet, healthy weight, quitting smoking, as well as control of blood pressure and cholesterol levels can greatly help many people maintain their mental ability in old age.
Understanding the reasons causing dementia progressed, and many risk factors usually precede a stroke, may also be indicative of Alzheimer's disease and vascular cognitive impairment.
«Recognition of risk factors of cognitive impairment - a promising method of preventing or at least delaying dementia, as well as savings in health care costs," - say the authors of the statement."We support the doctors who use screening tools to detect cognitive impairment in elderly patients and continues to struggle with risk factors for cardiovascular disease according to the guidelines adopted at national or regional level."
appearance of vascular cognitive impairment is most likely after a stroke, but the effects can occur even after a minor stroke, micro hemorrhages, or because of the appearance in the brain areas with poor bleeding, while not revealing the obvious neurological symptoms.
In many cases, risk factors for vascular cognitive impairment are exactly the same as in the case of stroke.These include high blood pressure, high cholesterol, abnormalities in heart rate and diabetes.The American Academy of Neurology and Alzheimer's Association support this statement.
