WASHINGTON, Sep 21 – RIA News. In addition to memory impairment, evidence of the onset of Alzheimer's disease can be caused by visual impairment, spatial orientation and difficulties with logical thinking, told RIA Novosti at the National Institute of Aging of the United States (National Instute on Aging) – the main structure for studying this disease in the United States.

World Alzheimer's Day is celebrated on Saturday. It is characterized by a loss of memory, the ability of rational thinking, the ability to navigate in space and care for themselves. The disease was first described in 1907 by the German psychiatrist Alois Alzheimer, from whom he got his name. Despite the fact that the disease has been known for more than a hundred years, scientists still do not have exact answers to many questions about it.

Scientists told how to slow down the development of Alzheimer's disease

There is no definite answer to the question of how to surely recognize Alzheimer's disease in yourself or your relatives. American experts note that "the first symptoms may be different in different people."

For example, memory problems may turn out to be a mild cognitive impairment that can lead to, but is not guaranteed to lead to Alzheimer's disease. Patients with mild cognitive impairment (Light Cognitive Imaprement, MCI) have worse memory than their peers, but the symptoms do not interfere with their daily lives, the organization explains.

"For many people, the signal for the beginning of the early stage of Alzheimer's is non-memory aspects of cognitive consciousness, for example, the problem of finding the right words, problems with vision and spatial orientation, impaired ability to reason logically and make decisions," the institute told part of the National Institute of Health (National Institute of Health).

The organization notes that the age of a person is still considered the main risk factor for Alzheimer's disease.

"Scientists believe that when and how Alzheimer's disease begins and progresses depends on many factors. The most important known cause is age. The number of people with this disease doubles every five years over 65," say experts at the institute.

According to the organization, today about a third of all people over 85 can have Alzheimer's disease. In the United States alone, the disease was diagnosed in 5.5 million people over 65 years of age. "As the population ages, these numbers will increase until ways are found to prevent or delay the development of the disease," they say at the Institute of Aging.

Experts suggest that a combination of genetics, lifestyle, and the environment may also matter, but "the significance of each of these factors to increase or reduce the risk of developing an Alzheimer's disease is individual."

Contrary to the view that sport helps with all illnesses, specialists from the US Institute of Aging admit that in the case of Alzheimer's, a moving lifestyle may not be a panacea.

"Based on the current studies, there is no evidence to recommend exercise as a way to prevent Alzheimer's-related dementia or mild cognitive impairment, which is characterized by memory problems and often leads to Alzheimer's type of dementia," the organization notes. .

Meanwhile, doctors emphasize that one should not forget that physical activity has a positive effect on health: even with aging, sports can help reduce the risk of falls, maintain mobility and independence, and reduce the risk of developing chronic diseases like diabetes, depression and high blood pressure.
