A simple way to reduce the risk of Alzheimer's disease: expert advice

With age, brain functions can start to fade Elderly people can develop Alzheimer's disease, which is accompanied by a decline in intelligence and memory impairment. Studies show that the probability of developing this condition is related to the quality of sleep.

Alzheimer's disease is associated with the accumulation of two substances in the brain – beta-amyloid and tau protein. During sleep, the concentration of beta-amyloid and tau in the blood decreases. If this does not happen, amyloid plaques and neurofibrillary tangles are formed. Because of them, connections between brain cells responsible for memory, learning and communication are broken.

An expert on sleep disorders, Narwan Amini, said that to reduce the risk of impaired brain functions, it is important not only duration of sleep, but also the position in which a person sleeps. From this point of view, she called the position on the side the healthiest position.

During sleep on the side, the most effective outflow of beta-amyloid and tau protein formations from the brain, the accumulation of which is associated with the development of Alzheimer's disease, is ensured. In addition, the position on the side provides support for the spine and reduces the likelihood of acid reflux, in which acid, normally located in the stomach, enters the esophagus and causes inflammation and pain.
