[Welfare News]With the aging society, the prevalence of dementia is also increasing, and in the case of ‘Alzheimer’s disease’, one of the representative diseases of dementia, amyloid abnormal proteins are deposited in the brain, causing brain damage and cognitive dysfunction.
There are several risk factors that cause ‘Alzheimer’s disease’, such as age and aging, cerebral infarction, diabetes, high blood pressure, hyperlipidemia, cardiovascular disease, smoking, drinking, family history, brain damage, etc. It has been shown to increase the risk of dementia.
Professor Han Su-hyeon of the Department of Neurology at Chung-Ang University Hospital said, “In Alzheimer’s dementia, various abnormal proteins accumulate in the brain, and the brain’s glymph system plays a role in cleaning these proteins. Sleeping well is the most important thing because it cleans proteins and wastes during the period.”
In fact, several epidemiological studies have revealed that there is a difference in cognitive function between the sleeping group and the sleepless group.
According to the Alzheimer’s Dis Assoc Disord study of 70-81-year-old women aged 70 to 81 years old, those who slept less than 5 hours had lower cognitive functions, including memory and attention, than those who slept for 7 hours or more. The overall cognitive function score was lower even when there were insomnia symptoms such as difficulty in waking up, maintaining sleep, or having regular sleep.
In addition, according to the publication of the International Journal of Sleep Medicine (Sleep Medicine), a prospective study conducted on elderly people over 65 years of age with normal cognitive function also found that sleeping less than 6.5 hours was associated with a decline in cognitive function following 10 years.
In a study conducted by the International Psychological Association (Psychol Bull) of school-age children aged 5 to 12 years as well as the elderly, it was confirmed that short sleep duration had an effect on cognitive functions such as executive function and performance ability, and was also associated with lower grades. done.
In fact, there is also a study confirming that the deposition of amyloid protein increases in brain PET-CT when sleeping for less than 6 hours.
As such, sleep disturbance can be a cause of dementia, so it is most important to develop a healthy sleep habit.
Professor Han Su-hyeon of the Department of Neurology at Chung-Ang University Hospital said, “For healthy sleep habits, it is necessary to find out the exact cause of sleep disorders. Because there are various types of disorders such as REM sleep behavior disorder, it is necessary to find and treat the root cause by a specialist.”
Next, Professor Han Su-hyeon said, “In order to sleep well, a high need for sleep, proper sleep timing and low arousal level must be in harmony in regular circadian rhythm. “It’s good to relax your body and stop thinking through deep breathing before going to bed, rather than paying too much attention to deliberately trying to sleep for control.”
To get a good night’s sleep, it is important to adjust the relationship between sleep and stimulus conditions that control sleep, such as bedtime, bedtime, and bedroom, by using the bed or bedroom only as a sleeping space and doing activities that interfere with sleep outside the bedroom. It is important.
Go to bed only when you are sleepy, never lie down when you are tired, get out of bed and come back when you are sleepy if you can’t sleep, and wake up at the same time every day regardless of your sleep time.
The longer you lie down without falling asleep, the lower your sleep efficiency, which makes it more difficult to get a good night’s sleep.
‘Sleep restriction therapy’ aims to increase sleep efficiency by artificially inducing mild sleep deprivation.
In addition, ‘relaxation therapy’, in which you breathe in for 5 seconds and breathe out for 5 seconds before going to sleep, can also help you sleep.
Professor Han Su-hyeon of the Department of Neurology at Chung-Ang University Hospital said, “‘Cognitive-behavioral therapy’, which corrects the wrong sleeping habits or beliefs that accompany chronic insomnia while repeatedly consulting regarding sleep, and enhances the understanding of sleep, is the top priority for chronic insomnia. If the treatment effect is good, you can cut down on the sleeping pills you are taking and quit. It is necessary to check and correct automated thinking regarding anxiety caused by excessive worry or insomnia due to health and psychological reasons,” he said.
Professor Han Su-hyeon continued, “It may be helpful to use an appropriate sleeping pill for temporary insomnia, but since it does not treat the cause of insomnia, the effect may be temporary. Therefore, it is necessary to be cautious in taking sleeping pills, and to take it following consulting with a sleep medicine specialist.”
