The hit drama “All is well” had its grand finale yesterday. The “old hero” of the drama, “Su Daqiang”, ended up with Alzheimer’s disease, also known as Alzheimer’s disease. Alzheimer’s disease (AD) is a chronic neurodegenerative disease that occurs with aging and is the most common type of dementia, accounting for about 60-70% of the causes of dementia. It is a terrible disease for which there is little good treatment. What can be done to avoid Alzheimer’s? We have the following suggestions: Eat right: The right diet can reduce the risk of cognitive decline. One of the most famous is a type of diet called Mediterranean-DASH. According to the results of a large study, this diet can reduce the risk of developing Alzheimer’s disease by 35% to 53%. To maintain social relationships: stay active. It is true that the level of socialization is a difficult indicator to measure, but talking regularly with others and communicating with each other is effective in reducing the risk of both diseases. We can exercise to effectively alleviate dementia, and studies have found that exercise can have the effect of reducing the risk of cognitive decline as well as the risk of Alzheimer’s disease. Avoid too little sleep: Studies have shown that too little sleep can lead to a decline in cognition and an increased risk of developing Alzheimer’s disease. It is also important to use your brain more, read books and newspapers, listen to music, play chess, practice writing and dance, all of which can give your brain a workout and delay the onset of dementia. As a cardiologist, we strongly recommend that you screen for atrial fibrillation because patients with atrial fibrillation, especially older patients with atrial fibrillation, have poorer attention span, word fluency, memory, psychomotor speed, and information processing speed than healthy individuals. Atrial fibrillation is significantly associated with decreased daily functioning and dementia, increasing the risk of cognitive impairment and dementia by 1.4 times and increasing the risk of post-stroke cognitive impairment by 2.7 times. The first step is aggressive anticoagulation, which reduces the incidence of cerebrovascular events and dementia, while radiofrequency ablation is a very effective option for patients with a rapid heart rhythm that results in reduced cardiac pumping.
