[Alzheimer's disease]
1. Alzheimer's disease, also known as Alzheimer's disease . The sick person will gradually lose his mind and eventually lose his ability to take care of himself until he dies.
2. Alzheimer's disease has been ill for a long time and can live with the disease for 20 or 30 years. The patient's quality of life is extremely poor. It is a very terrible disease.
3. Compared with normal people, brain slices with Alzheimer's disease are extremely different. They are dry and empty.
4. Alzheimer's disease has no cure. Patients can never recover to normal intelligence. It is useless to rely on careful care. It can only make the patient's survival better.
5. The β amyloid is abnormally increased around the atrophic brain cells of patients with Alzheimer's disease, blocking and damaging nerve cells.
[ Alzheimer's and amyloid]
1. The direct cause of Alzheimer's disease is the degeneration and death of brain cells. The atrophic brain causes humans to lose their ability to take care of themselves, and amyloid beta can directly lead to nerve cell degeneration.
2. The content of amyloid beta exceeds a certain threshold, which will cause significant damage to the brain. The higher the proportion exceeding the threshold, the faster the brain cells will degenerate and die.
[Brain Cleaning Mechanism]
1. Sleep helps to clear away harmful metabolites accumulated by the brain when it is awake and consolidates memory.
2. During sleep, the brain's "cleaner" - the movement of cerebrospinal fluid entering the lymphatic system increases, thereby promoting waste removal.
3 and lymph enter the brain, and the control of circadian rhythm is worth studying.
4. High-quality sleep at night helps more "cerebrospinal fluid" enter the brain to clean up garbage. During the day, "cerebrospinal fluid" transports this garbage out of the brain and promotes long-term health of the brain.
[Sleep is divided into 4 stages]
1. Sleep stage; humans are easily awakened, which accounts for about 2~5% of sleep time.
2. Light sleep stage; humans gradually lose perception, which accounts for about 45 to 55% of sleep time. You will respond to external stimuli and know what is happening around you.
3. Slow-wave sleep stage; which is commonly known as the sleep stage, which accounts for 15 to 25% of the total sleep. You will lose all reactions to external stimuli, your brain falls into a state of crash, and you don’t know what is happening around you.
4. REM sleep stage; that is, a stage of dreaming, which accounts for 25% of the total sleep, the brain gradually returns to activeness, and people begin to dream continuously.
[Brain Cleaning and Sleeping]
1 In the human sleeping stage, blood will flow out of the brain on a large scale, so the brain will lose consciousness and enter a state of crash.
2. When blood flows out of the brain, cerebrospinal fluid will pour in on a large scale, filling the blank area where blood flows out.
3. When the brain regains consciousness, blood will flow into the brain again, and cerebrospinal fluid will flow out, taking away some waste generated when the brain is running, including amyloid beta.
4. Light sleep mode cannot remove the beta amyloid produced in the brain of volunteers. At the same time, even after sleeping for 8 to 10 hours, the volunteers still feel groggy.
5. In 7 to 9 hours of sleep, only 15 to 25% is deep sleep time, that is, the time when blood exits the brain, allowing your brain to get real rest and cleans and detoxification.
[How to have good deep sleep]
1. Regular sleep.
Sleeping and getting up at a fixed time will help you better enter the deep sleep period.
2. Try to complete the last meal three hours before sleeping, and control the time of the last snack 90 minutes before bedtime, because late-night snacks will affect our sleep.
3, noise, stress, thoughts, caffeine and other physiological interferences are all obstacles in the sleep process. Avoid coffee and strong tea intake before 4 pm.
4. Eat more foods that help you sleep. Chicken, fish, bananas, milk and nuts, tryptophan is an essential raw material for the synthesis of serotonin and melatonin. Calcium and magnesium use tryptophan to make melatonin. When you are having difficulty falling asleep, you can consider supplementing calcium and magnesium.
5. Increase the amount of exercise during the day and avoid doing exercise before going to bed at night.Before going to bed, you can try meditation to empty your brain, which will help you get into deep sleep better.
6. Actively regulate the cervical spine, and perform precise minimally invasive relaxation treatment under the guidance of muscle bone ultrasound to assist in blocking the stellate ganglion, improve blood supply to the brain, enhance autonomic nerve function, and promote deep sleep.
