Dementia - the curse of a rapidly aging civilization, as reported by the Internet publication for girls and women from 14 to 35 years Pannochka. net New research demonstrated that lovers of sleep suffer from dementia twice as often.
The latent danger of prolonged sleep is reported on the pages of the new issue of Neurology.
Dementia and Alzheimer's Disease in Figures.
Dementia unites various by nature diseases characterized by gradual deterioration of thinking and memory, behavioral disorders, decreased motivation, speech impairment and loss of independence.
In most cases, the cause of dementia is Alzheimer's disease (up to 70%), followed by vascular dementia (up to 25%), dementia with Levy bodies, frontotemporal dementia. For rare reasons include Parkinson's disease, syphilis, mad cow disease.
In 2015, the number of patients with dementia in the world reached 46.8 million people. According to the forecasts of WHO experts, this number will almost double every 20 years, exceeding by 743 by 2030, 131 million by 2050.
A particularly rapid increase in the incidence of dementia is expected in developing countries, where life expectancy increases and the population begins to age. Today, only 58% of patients are in low- and middle-income countries, but by 2050 their share will grow to 68%.
The most rapid aging of the population is observed in China, India and their closest Asian neighbors. It is there that the epidemic of dementia is expected.
Today in the countries of the West with highly developed medicine, 1 in 3 old people die as a result of Alzheimer's disease or another form of dementia. The world's largest economy (the US) loses $ 236 billion annually because of dementia and its consequences.
9-hour sleep increases the risk of dementia by half.
The search for new ways of preventing dementia was undertaken by the staff of the medical faculty of Boston University, led by Dr. Sudha Seshadri (Sudha Seshadri), a university professor of neurology.
The scientists analyzed data from the Framingham Heart Study (FHS), a large cohort study begun in 1948 in the American town of Framingham and involving more than 5.2 thousand men and women of middle age (30-62 years).
During the 10-year study participants were regularly asked about the quality and duration of sleep. It remains to compare this information with the state of intelligence.
It turned out that lovers of sleep nine hours a day are twice as likely to suffer from dementia.
In addition, Dr. Seshadri confirmed the enormous role of education in preserving the cognitive abilities of the elderly. FHS participants with higher education developed dementia 6 times less frequently than their illiterate peers.
Further - more interesting.
It turned out that in lovers of sleeping the volume of the brain is on average slightly less than the rest. Why - it is not clear, however, the authors see in this the first signs of neurodegenerative changes, concomitant dementia.
According to their hypothesis, prolonged sleep is not a cause, but a symptom of degenerative changes in the brain, so early ascents will not delay Alzheimer's disease.
Whatever it was, Dr. Sesadri's study was observational, and his intriguing findings are far from final approval. Clearly only one: if at you in due course there was a raised or increased requirement for a dream, it is desirable to address to the doctor and to pass or take place inspection.
Early diagnosis of dementia allows you to most effectively fight the disease and keep the mind for a long time!.
