Alzheimer's Harmo's disease is one of the "Alzheimer's Harmo's diseases" that we often talk about. With the deepening of aging, its incidence trend is increasing year by year.
According to the recently released Investigation Report on the Diagnosis and Treatment of Patients with Alzheimer's Harmo's Disease in China, the data show that:
There are 50 million dementia patients and 38.77 million mild cognitive impairment patients in the world. It is predicted that by the middle of this century, the number of patients in the world will increase to more than 654.38+0.5 billion, and the number of patients in China will also exceed 40 million.
It can be seen that how to prevent Alzheimer's disease has become particularly important. First, we need to know its cause.
Nature News recently published a study by the University of Paris. Researchers conducted a 25-year investigation and analysis on 10308 British civil servants aged 35-55, and found that the short sleep time of adults was positively correlated with the onset of Alzheimer's disease.
The researchers divided the participants' sleep time into three categories, one is less than 6 hours, the other is about 7 hours, and the last is more than 8 hours. Then follow up every 4-5 years.
In the follow-up data, it is concluded that sleeping less than 6 hours a day increases the risk of dementia by 63%.
This study can prove to some extent that adequate sleep is an effective way to resist Alzheimer's disease. But besides, there are other factors that can also induce dementia.
In 20 17, The Lancet published a comprehensive report, which listed the pathogenic factors leading to Alzheimer's disease. The most important factor is heredity, and the acquired factor accounts for 35%.
Specifically, it includes deafness after middle age (the risk of illness increases by 9%), low education (8%), long-term smoking (5%), depression (4%), lack of social interaction, diabetes, hypertension and obesity in old age (2%).
In 2020, The Lancet added three more factors in its second comprehensive report, namely, brain injury in middle-aged people (3%), long-term excessive drinking in middle-aged people (1%) and poor living environment in the elderly (2%).
Although congenital genetic factors are difficult to change, as long as attention is paid, the risk of acquired illness can be reduced as much as possible. In addition, we should know the symptoms of Alzheimer's disease. Once found, seek medical attention in time.
Professor Zhang Nan, member of the Standing Committee and Deputy Secretary-General of Harmo's Disease Branch of China Geriatric Care Association, said that Alzheimer's Harmo's disease is a syndrome, and Alzheimer's Harmo's disease is one of the causes. If the elderly have the following 10 manifestations, it may be a precursor of Alzheimer's disease.
1, memory loss
Old people may forget their keys, forget things in life, or have no memory of recent activities.
2. The planning ability is declining.
For example, if you want to entertain guests at home, you can't arrange in advance how many people will come, what food to eat, who will attend and what you need to pay attention to.
It is difficult to finish the familiar work.
It used to be very handy to cook at home, but now it will be very difficult to fry a few more dishes.
4. I can't tell the place and time, and my sense of space is wrong.
I can't remember where and when, and I can't tell the shape and attributes of things.
5. Difficulties in language expression
It's hard to say, familiar words can't be said, and mistakes often appear in expression.
6. Things that are often misplaced
Put the rice cooker on the gas stove, and you won't find anything misplaced.
7, the ability to judge decline
There are mistakes in judging various external affairs, and unreasonable mistakes are often made.
8. Close yourself and change your mood.
Unwilling to socialize and not interested in anything; Some people become moody, while others have depressive symptoms.
If the elderly around you have the above symptoms, you need to have a nervous system examination and neuropsychological evaluation. In addition, cognitive examination, EEG, neuroimaging, PET examination, cerebrospinal fluid examination and blood examination should be carried out.
First of all, weight control, obesity will increase the risk of diabetes and cardiovascular disease. Body mass index (BMI) should be controlled between 18.5-24. Relatively speaking, for people aged 65, this index can be improved.
Secondly, protect your hearing and pay attention to controlling the volume and duration. The risk of mild to moderate hearing impairment in the elderly is 2 times, 3 times and 5 times that of the normal elderly.
Furthermore, think more and participate in social activities, such as reading books and newspapers, playing chess and cards. Make sure you get enough sleep.
Finally, the research shows that insisting on exercise can reduce the risk by 45%, and keep aerobic exercise for more than 30 minutes every day for 5~7 days.
In life, the elderly can know whether they are prone to cognitive impairment through the following questions. Just answer every question: yes, there are changes; No, it hasn't changed.
If more than two of the eight problems have changed, you need to see a doctor for further examination.
Only when we are young and middle-aged, do a good job of prevention and respond with a healthy lifestyle can we reduce the risk of Alzheimer's disease. Therefore, adults should immediately change their diet, exercise and routine.
