Now there are more and more reasons to drink. I'm in a good mood, I want to have a drink When I'm in a bad mood, I drink to relieve my sorrow From the sun exploding to ants moving Can be a reason to have a meal Image source: Publish In fact, many people have become dependent on alcohol. I just haven't noticed yet. Drink to your heart's content But Dr. Huaxi reminded everyone Excessive drinking has risks May cause Alzheimer's disease! Senile dementia, scientifically known as Alzheimer's disease. In recent years, people have paid more and more attention to Alzheimer's disease, and it can be said that it has reached the point where people are terrified by the mention of it. Alzheimer's disease (AD) is a neurodegenerative disease with an insidious onset and progressive development. Its clinical features are mainly cognitive impairment, mental and behavioral abnormalities, and decreased social function. —— "Guidelines for the Diagnosis and Treatment of Mental Disorders (2020 Edition)" Due to cognitive impairment, patients with Alzheimer's disease often have difficulty taking care of themselves. Suddenly you can’t find the way home that you take every day, you suddenly don’t recognize your closest family members, and you forget what you did just a few minutes ago in the next second - these are all symptoms of Alzheimer's disease, which bring unspeakable pain to yourself and your family. Image source: Photo Network Currently, it is generally recognized that the imbalance in the production and clearance of β-amyloid protein (amyloid-β, Aβ) is the initiating factor of neuronal degeneration and dementia. Abnormal levels of amyloid-β form plaques between neurons in the brain that are neurotoxic and lead to neuronal degeneration. In recent years , the brain inflammatory response hypothesis, intestinal microbial hypothesis, herpes virus hypothesis, Porphyromonas gingivalis hypothesis and so on have been proposed. Image source: Photo Network Don’t understand? It doesn’t matter. In simple terms, there is too much toxic protein Aβ, which makes the brain unable to function. It is still related to the Aβ protein mentioned above. Current research has found that alcohol has the following four main mechanisms of action on Alzheimer's disease: Makes toxic proteins difficult to remove Microglia are immune cells that can help us clear the toxic protein Aβ, but long-term drinking can inhibit the function of these cells , increasing the risk of Alzheimer's disease! Image source: Photo Network Causes the toxic protein to grow wildly To explain this clearly, we must first understand where Aβ protein comes from. There is something called hippocampal APP in the brain, which produces Aβ toxic protein under the catalysis of the enzyme BACE-1. Image source: Photo Network Then some scientists did an interesting experiment: Scientists divided mice that looked similar into two groups, one that was fed alcohol every day and the other that was not. After five weeks of experiments, they found that the BACE-1 enzyme and hippocampal APP in the mice that drank alcohol every day increased. In other words, the production of Aβ toxic protein in alcoholic mice increases, and the probability of developing Alzheimer's disease increases! Causes normal protein to stop working Tau protein is an important protein that allows our brain to respond normally. When we drink too much, Tau protein will become over-phosphorylated. When Tau is overphosphorylated, the brain cannot function properly, which can also become a major cause of Alzheimer's disease. Image source: Photo Network Liver damage can also increase the incidence of Alzheimer's disease As we all know, drinking alcohol will definitely damage the liver. Once the liver is damaged, it will promote the release of cytokine TNT-α by cells in the liver. This cytokine TNT-α will also increase the probability of developing Alzheimer's disease! Image source: Photo Network In addition to the above, further scientific research has also shown that long-term drinking can worsen metabolic regulation in the brain and peripheral tissues - another way to accelerate the progression of Alzheimer's disease. In summary, regular and heavy drinking increases the risk of Alzheimer's disease. Alzheimer's disease is a currently incurable disease that will have a great impact on daily life and family happiness. Drinking makes you feel good for a while, but for the long term, don’t drink too much! Statement: This article is a medical-related educational popular science article.
