Alzheimer’s disease
Many people will find decline in memory and thinking ability as they grow older.In the beginning,these changes may difficult to be found.And it can easily be considered as normal phenomenon.It is indeed possible.But they may also be the early symptoms of Alzheimer’s disease.With the aging of the population,Alzheimer's disease has gradually become a big killer of human's lives,and it has also attracted more and more people's attention.
In 1901, the first patient with similar symptoms was treated by alois Alzheime in Germany. The examination showed that she had no problem with her body at that time.However, the patient's condition was getting worse and worse and eventually died after five years. thereafter, scientists called this disease Alzheimer's disease.
Alzheimer's disease,called AD for short,is the most common form of Dementia （失智症）,about 60 persent to 80 persent.The sufferers of Alzheimer's disease have difficulty recognizing familiar people and things,And they can't find suitable words to describe things.Their characters and ability to judge will also change.At the later stage of their disease,they can't even remember their wives,their husband,their children.forget how to walk,how to eat.Finally leave the world.
Nowadays,the number of people dying from Alzheimer's disease is increaseing year by year.According to statistics, Alzheimer's disease has become the fifth cause of death for Chinese people by 2017, And the average age of death is 5.9 years. In 2019, there are more than 52 million Alzheimer's disease patients in the world and more than 10 million in China, This number is twice that in 2010, seven times that in 1990 and is still increasing. It is estimated that by 2050 there will be 28 million patients in China and 152 million in the world.
Facing Alzheimer's disease,we are not helpless.Not long ago,an American biological claims that they have developed effective drugs to treat Alzheimer's disease.And having a healthy diet,doing exercise regularly, participating in more social activities are also helpful to patients.And I believe with the development of medical science,we will finally defeat Alzheimer's disease some day.。
