Can Alzheimer's disease be inherited

Update Date: Source: Network


I believe that we all know about hereditary diseases, that is, diseases that will be passed on to the next generation. Of course, these diseases are determined by a chromosome in the gene, so we will see many people suffering from the same disease in a family. Let's share with you the common problem of whether Alzheimer's disease can be inherited!

Can Alzheimer's disease be inherited

First: Alzheimer's disease is a neurological disease. Generally, the elderly are the most, so many people call it Alzheimer's disease according to its symptoms. There are many manifestations of Alzheimer's disease, some can't recognize people, some can't remember things. Their world is like a boat hovering in the middle of a lake. What they see is always where they are. They no longer have the courage to ride the wind and waves when they were young, but stay there day by day and wait.

Second: epidemiology shows that 5% of Alzheimer's patients have a clear family history, and those who inherit the mutant gene will show dementia in the course of life. The mutation gene has been identified as autosomal dominant inheritance, which is a polygenic disease. It is known that chromosome 1, 14, 19 and 21 are related to the pathogenesis of Alzheimer's disease. Amyloid precursor protein (APP) gene is located on chromosome 21, presenilin-1 (ps-l) gene is located on chromosome 14;

Third: the younger the onset age (usually about 40 years old), the more likely to have genetic tendency. The risk of suffering from this disease is many times higher than that of people without family history, but not necessarily all of them. Therefore, if there are relatives at home with Alzheimer's disease, they should go to the hospital for preventive examination as soon as they are over 50 years old.

matters needing attention

Through the above introduction, I believe we have understood, will Alzheimer's disease be inherited? It's hereditary, and the disease is very harmful to us and the burden on our family. Therefore, if there are people with Alzheimer's disease in the family, we must do a good job in prevention as soon as possible, and go to the hospital for examination after 50 years old. This is also particularly responsible for our own health.
