Several common misunderstandings about Alzheimer's disease
For more than 0 Over the past year, scientists around the world have conducted a lot of research on the causes of Alzheimer's disease , but the cause so far is still unclear. Many evidence suggests that psychosocial factors, cerebrovascular factors, environmental pollution, chronic poisoning, and immune disorders are closely related to the onset of the disease, especially cerebrovascular diseases and environmental pollution can accelerate the development of Alzheimer's disease. There are also many misunderstandings about Alzheimer's disease in clinical practice.
people with Alzheimer's disease?
people reach the age of old age. Although brain cells have deteriorated to varying degrees, resulting in a decline in brain function, the functions of most surviving brain cells still exist. Moreover, these surviving brain cells have certain compensatory functions and can maintain normal mental activities. In recent years, research has confirmed that brain cells can gradually stop degenerating to around 90 years old. Clinically, only 4% to 5% of the elderly suffer from dementia, which shows that most elderly people have healthy brain functions. They can not only live normally, but also maintain a certain level of learning and work ability.
Is the elderly dementia if they have poor memory?
Memory can be divided into three types: moment, recent events, and far-reaching events. Among them, recent events memory decreases more significantly as you age, while instant and distant events memory decreases more slowly. Therefore, in daily life, the elderly still remember things that have been gone, but are easily forgotten about things that have happened recently. However, most elderly people have a milder degree of memory loss and will gradually stop. Although these elderly people feel that their memory loss does not affect their daily life, and intelligent examinations are also normal. They are called "physiological memory loss" in medicine. Of course, if the degree of memory loss is severe and has affected daily life, it is dementia. Therefore, poor memory in the elderly may not be a manifestation of dementia.
Whether it is dementia, you will know if CT is checked!
Most healthy elderly people, CT test can show varying degrees of physiological brain atrophy, but they do not have symptoms of dementia. On the contrary, in some elderly people, CT tests show that there is no brain atrophy and , but they have symptoms of dementia. According to the survey, about 20% of patients with Alzheimer's disease have normal CT tests. Generally speaking, the diagnosis of dementia mainly depends on clinical symptoms. If there are no symptoms of dementia and CT scans show brain atrophy, it proves that this is a normal physiological degeneration of brain tissue and there is no need to be nervous.
Alzheimer's disease cannot be cured, so there is no need for treatment!
For Alzheimer's disease, although current medical technology cannot reverse or cure the disease, it can improve cognitive and mental state, reduce complications, delay the development of the disease, improve the quality of life of patients, and reduce the burden on patients' families.
The treatment methods for Alzheimer's disease are usually drug treatment combined with personalized cognitive and exercise rehabilitation.
Light diet and sleeping more can prevent Alzheimer's disease!
Scientific research has found that some so-called good habits may actually be risk factors for Alzheimer's disease.
For example, a light diet. Many people believe that a light diet is equivalent to eating vegetarian food for a long time, or even not eating oil and salt. Eating vegetarian food for a long time may cause a variety of nutritional deficiency, which can instead cause Alzheimer's disease. Therefore, the elderly should pay special attention to balanced nutrition and eat high-quality protein such as fish, eggs, lean meat, etc. to ensure the intake of vegetables and fruits. Oil and salt need to be controlled, but not eating them at all is even more harmful to the body.
Deficiency of sleep may be an influencing factor of Alzheimer's disease, but sleeping too much is also dangerous. A Framingham Heart Study in the United States found that elderly people who sleep more than 9 hours a day have a twice as risk of developing Alzheimer's disease than ordinary people. For most adults, it is recommended that 7-8 hours of sleep per day be more appropriate, while maintaining regular schedules, but sleep time is not absolute. There are individual differences, and sleep quality and subjective feelings should also be considered.
