Sleep is one of the most important things in one's life, and lack of sleep can cause many problems. If sleep is insufficient or poor quality, it is possible to cause cognitive dysfunction. So what are the problems of cognitive dysfunction?
Let us go into today's "NetEase Health public class", to listen to the first hospital of Hebei Medical University Mental Health Research Institute Director of Professor Wang Xuiyi told, sleep enough will cause problems?
1. What are the problems caused by poor sleep quality? Wang Xuiyi: Sleep is a very important human physiological and psychological needs, human life is about one-third of the time in sleep, if the squeeze sleep time will appear a lot of problems, first, physical health, such as when we sleep well, high blood pressure, blood sugar may also increase, and some of the original body disease,
Psychosomatic diseases can worsen. Second, mental health effects, long-term sleep is not good sleep may have a lot of problems, especially cognitive function problems.
For example, people who stay up late, have poor sleep quality, wake up early or have no continuous sleep, the second day of attention and learning, working memory is significantly worse than the number of people who sleep well.
Excessive sleep in the elderly may also be a sign of dementia, or sleep too little to reach deep sleep, always a light sleep state, can also trigger cognitive impairment. In addition, if the original cognitive function impairment, like MCI mild cognitive impairment, the original dementia will be more heavy.
In clinical practice, it is found that people who sleep poorly sleep incorrectly, in fact, sleep rhythm disorder. Teenagers now have some unhealthy lifestyles, squeezing sleep time to play mobile phones, watching computers, reading books. The study found that people who slept poorly before the age of 20 and 60 years of age were significantly higher in cognitive impairment or dementia than those without sleep problems.
This also suggests that sleep problems are not only the patent of the elderly, but also some cognitive function changes in the young people's long-term insomnia.
2, why does sleep affect cognitive function? Wang Xuiyi: Sleep affects cognitive function as a result of a variety of causes. It could be a genetic problem, or it could be a life event. There are genetic factors, but I think it is mainly due to the acquired factors in addition to genetic factors. The congenital factor is probably only 30%, the acquired factor will occupy 70%. The environment, life style, cognitive problems and so on will directly affect the sleep problem.
Sleep problems also lead to cognitive impairment, which leads to depression, and this interaction is very obvious. Just like the machine, the daytime is over-functioning, the night is not resting, no maintenance, sleep, the machine will be dysfunctional.
Today we are only talking about cognitive impairment, and other aspects of the body, such as mental problems, are affected.
3. What are the specific cognitive functions? Wang Xuiyi: Cognitive function includes many, the first is the attention function, cognitive dysfunction will pay attention to LAX.
Second, work learning memory, poor attention to bring bad memory problems, in turn, aggravating the burden of his mental state, the more the burden of more tension and more problems occur. Third, the executive function, such as the decision on things indecisive, spear contradiction shield, unlike in the past to make a decision quickly.
Cognitive dysfunction is particularly significant in the three parts of attention, learning working memory and executive function. These three functional aspects will affect our quality of life, the quality of work, the other judgment, decision-making ability will be affected. For example, senile dementia can not make decision-making things, do not know how to do, attention, memory is significantly reduced, some people may see this is a normal old man, in fact, from the angle of sleep, from the cognitive function point of view will be found early Alzheimer's disease.
