New research from scientists at Johns Hopkins University shows that people who feel sleepy during the day, maybe three times as likely to develop Alzheimer’s disease. Tracking 123 volunteer for 16 years, experts have discovered that whatever the reason – be it lack of sleep, stress or something else – drowsiness in the daytime was associated with a higher risk of neurodegenerative diseases.
According to experts, the obtained results demonstrate that sleep is an important component of our health. Factors such as diet, exercise and cognitive activity, are widely recognized as important potential targets for the prevention of Alzheimer’s disease, but sleep in these factors are usually not included. However, in the near future things can change, sure the doctors. If disturbed sleep contributes to the development of Alzheimer’s disease, patients with sleep problems can get treatment to avoid health problems later in life.
During testing, the researchers interviewed participants on the topic of sleepiness in the daytime, and then periodically assessed health using brain scanning. The researchers wanted to find out whether there is a relationship between people who reported daytime sleepiness, and the presence of toxic beta-amyloid plaques in their brain. The results showed that the subjects who experienced sleepiness during the day, were three times more prone to deposition of beta-amyloid protein than those who did not report daytime sleepiness.
It is still unclear why daytime sleepiness is associated with accumulation in the brain of beta-amyloid protein, experts say. Perhaps drowsiness during the day disrupts the chemical balance in the body, resulting in the brain begins to form a dangerous protein. However, it is more likely that poor sleep quality causes the accumulation of beta-amyloid plaques.
