A person suffering from Alzheimer's much chance of

Dozens of diseases including senile dementia, senile dementia of the most common for Alzheimer's disease (Alzheimer's disease) and vascular dementia, both of which accounted for 70% of senile dementia -80%. When a person is old when he is suffering from Alzheimer's chances What are the odds? In response, Beijing Xuanwu Hospital Department of Neurology Alzheimer's expert, said Professor Zhang Xinqing, according to the survey of Xuanwu Hospital, Beijing prevalence of dementia in the elderly over the age of 60 to 5.1 percent, with age, a gradual increase in the prevalence rate; there Reports indicate that the incidence of the 80-year-old will be increased to 40%. In an aging society, and gradually extend the human life span. When a person is slowly getting older, their risk of suffering from Alzheimer's will increase gradually; and, as life events, such as cerebral vascular disease, head injury, Alzheimer's prevalence rate is relatively higher risk Age disease may be moved forward. According to Zhang Qing, senile dementia, including dozens of diseases, senile dementia of the most common for Alzheimer's disease (Alzheimer's disease) and vascular dementia, both of which accounted for 70% of senile dementia -80%. Alzheimer's exact cause remains unclear. From the pathological point of view, expressed in the brain to shrink, reducing the number of nerve cells, cells with the formation of tangles of nerve fibers, there is extracellular amyloid deposition, the impact of changes in the brain, leading to decreased intelligence, life can not take care of themselves. Vascular dementia is due to a variety of causes cerebral vascular disease, such as multiple brain stem caused by brain damage, leading to a decline in cognitive function.
