Alzheimer’s disease was first described in 1907 by a German psychiatrist Alois Alzheimer. According to statistics, about eight people per thousand of the population suffer from this disease. And the older a person is, the more likely he is to have this disease. At what age does the disease start, aif.ru told Deputy Director for Research, Head of the 1st Neurological Department of the Scientific Center of Neurology, Corresponding Member of the Russian Academy of Sciences Marine Tanashyan:
“Alzheimer’s disease is an age-related disease. Basically, the disease overtakes people of elderly and senile age.
According to statistics, at 65 years of age, Alzheimer’s disease is recorded in 0.3% of people, at 75 years old – in 1%, at 80 years old – in almost 2.5%. As for the age over 85 years, there are rather conflicting data on this score. Some believe that the disease overtakes 4% of people of this age, and according to the statistics of the Scientific Center for Neurology, about 30% of people over 85 years of age are affected by Alzheimer’s disease or other cognitive impairments.
Every year the prevalence of the disease is growing. In 2018, for the first time in history, the number of people over 65 exceeded the child population (children under the age of five), and there are more older and older people, including centenarians, on the planet. In this regard, it is possible to predict an increase in the number of patients with cognitive dysfunction. If today 55 million people suffer from Alzheimer’s disease in the world, then by 2050 there will be 139 million of them.
