"One", what are the early manifestations of Alzheimer's disease? The onset of Alzheimer's disease is often hidden and unnoticed. Therefore, it is very important to correctly understand the early symptoms of dementia, so that patients can get timely treatment and delay the progress of the disease. In the early stage of dementia, memory impairment is very prominent, and patients tend to forget things. In the initial stage, they forget recent events, such as the food they just ate a few hours ago. As the disease worsens, long-distance memory will also be affected, such as being unable to recall past experiences. Some patients show emotional disorder, early emotional instability, emotional fragility and easy to shed tears, depression when things happen, anxiety about trivial matters, fear and so on. Some patients have cognitive impairment. At first, you may be upset, distracted, repetitive, indecisive and indecisive, which is in sharp contrast to your previous shrewdness. Some patients have psychological disorders. Because of amnesia, they don't know where to put things, and they always suspect that someone has stolen his things. Some patients feel unwell and seek medical advice everywhere. Although no abnormality was found, they still felt pain. Patients with sexual dysfunction often suspect that their spouses are having an affair, so the family often quarrels. A few patients behave abnormally, become too frugal and collect waste everywhere. Some patients compare their simple sketches with those drawn by famous artists. Some patients often go to the wrong house in the new environment. The above early symptoms will not appear at the same time. Once similar symptoms appear, you should immediately go to a specialized hospital for psychological consultation, and carry out necessary psychological tests and nervous system examinations to facilitate early diagnosis. Second, how to prevent the occurrence of Alzheimer's Harmo's disease: The prevention of Alzheimer's Harmo's disease should start from middle age, because Alzheimer's Harmo's disease can be found in pre-dementia or early dementia, and corresponding measures should be taken in life and persisted, and its development can be completely controlled and turned into a good direction to some extent. According to the recent research results, the main measures to prevent Alzheimer's Harmo's disease are: avoiding cerebral arteriosclerosis, cerebral thrombosis and other diseases, thus preventing Alzheimer's Harmo's disease caused by insufficient blood supply to the brain. Atherosclerosis is the main "enemy" of Alzheimer's disease. Adjusting diet, eating less salt, and taking appropriate physical activities are helpful to prevent arteriosclerosis. Pay attention to intellectual training, use the brain frequently, and delay brain aging. Studies have shown that doing something interesting often can keep your mind sharp and exercise your brain cells to react quickly. However, if you do nothing all day, you will get Alzheimer's disease. Old people should stay active and use their brains more, such as reading more books and learning more new things; Cultivating hobbies can activate brain cells and prevent brain aging; Pay attention to extensive contact with people from all walks of life, such as chatting with friends, playing mahjong, playing chess, etc., which can stimulate the vitality of nerve cells. Strengthening mental conditioning People often say, "Smile and you will be ten years old", so we should pay attention to maintaining an optimistic mood, that is to say, we should be quiet and fearless, indifferent to nothingness, contend with the world, be content with contentment and be pure in heart. Don't be tempted by external material desires, don't be disturbed by internal emotions, and make contributions to health. Pay attention to maintaining interpersonal relationships and avoid falling into depression for a long time, because depression is a risk factor for dementia in the elderly, and mental stimulation should be avoided to prevent brain tissue function from being damaged; In addition, maintaining family harmony can maintain a happy mood and enhance disease resistance. Strengthening physical exercise Many people know that exercise can reduce the risk of stroke. In fact, exercise can also promote the production of nerve growth hormone and prevent brain degeneration. In addition to full body movement, try to move your fingers. Generally speaking, going to bed early and getting up early, eating regularly and defecating regularly are of positive significance to prevent the occurrence of Alzheimer's disease. In diet, it is emphasized to achieve "three determinations, three highs, three lows and two precepts", and "three determinations" means timing, quantitative and qualitative; "Three highs" means high protein, high unsaturated fatty acids and high vitamins; "Three lows" means low fat, low calorie and low salt; The "two precepts" are quitting smoking and drinking. The elderly should supplement more beneficial minerals and trace elements, and lack of necessary trace elements (such as zinc) will cause insufficient blood supply to the brain and cause vascular diseases. Appropriate vitamin E supplementation can enhance memory and help prevent Alzheimer's disease. In addition, the elderly should eat more fish. A study conducted by Dutch scientists on 5,000 elderly people over 55 years old shows that the elderly who eat fish regularly are only 0.4 times more likely to develop Alzheimer's disease than those who don't eat fish.
