A blood type, B blood type, O blood type, AB blood type, which blood type people have a high risk of Alzheimer's
Are you type A, B, AB or O? Why do humans distinguish between different blood types?
The antigens on the surface of red blood cells mainly depend on the classification of blood types. Type AA blood contains antigens, type B blood contains B antigens, AB type blood has two antigens at the same time, and O these two antigens are not the same.
In addition, blood type is also related to health. A study in eLife involving 5.1 million people found that as many as 49 diseases may be associated with ABO blood type. Is your blood type the perfect blood type?
- Different blood types lead to different brain aging speeds?
Do you think blood type has anything to do with Alzheimer's disease? Some studies suggest that type O blood is better for cognitive function, but there are also studies that suggest that type O blood is better for cognitive function.
By comparing the difference in gray matter volume between type 0 and non-O blood groups, some scholars have found that individuals with type 0 blood have more gray matter content in the brain. Specifically, the cerebellum and temporal lobe had higher gray matter content. As an important part of the central nervous system, the gray matter of the brain is related to memory. In people with Alzheimer's disease, gray matter content in these brain regions is reduced.
A large study involving more than 30,000 people had a mean follow-up of 3.4 years. During the study, the researchers tested the participants' cognitive function to see if there was any decline. Tests include verbal fluency, immediate memory, orientation, and the ability to learn words. A total of 495 people had significant cognitive decline at the end of the study.
After comparison, it was found that people with cognitive impairment had ab blood type accounting for 6%. The findings suggest that people with AB blood types and higher levels of FVIII may be more prone to cognitive impairment. Concentrations of FVIII, a protein that helps blood clot, have been linked to cognitive impairment and dementia. Across all blood types, people with the higher AB blood group had almost 40 percent more FVIII than those with the lowest O blood group.
Compared with other blood types, people with AB blood type have an 82% risk of developing cognitive impairment, and it is speculated that people with AB type may be more prone to brain diseases in later life.

Two, type A, type B, type O, type AB, which blood type is the most perfect?
AB has a higher risk of Alzheimer's and cardiovascular disease, so what are the risks for other blood types?
blood type O
A study in the Journal of Diabetology found that blood type may affect the risk of diabetes among those who belong to universal transfusion recipients. Among all blood types, the risk of O2 diabetes is relatively low.
Chemotherapy-induced CIT for non-hematological malignancies is a common complication that can cause a range of health problems in cancer patients, including spontaneous bleeding. The researchers believe that the incidence of CITO blood is higher, but this needs to be further verified.
The most common type of hemolytic disease of the newborn is ABO, and the proportion of blood group incompatibility is as high as 95%. Patients usually present with pale skin, jaundice, and edema.
Clinical data show that children born to mothers with type O blood may be more likely to have ABO incompatibility hemolytic disease. This is because women with blood type O have more natural anti-A or anti-B IgG antibodies, and these small molecule antibodies can pass through the placenta into the fetus, causing hemolytic disease of the newborn.
Type A blood
In 2014, a study was published in the Journal of Clinical Oncology, with an average follow-up of 27 years, a total of 6,304 respondents, and found that blood type A had a higher risk of developing cancer.
The researchers observed a significant positive correlation between the presence of the alpha antigen in the blood and the initiation and progression of cancer. However, the current research on blood group and tumor pathogenesis is not enough.
A study in the Journal of Clinical Investigation found an increased risk of severe acute respiratory distress syndrome in A after severe trauma and sepsis.
blood type B
Among all blood types, B-related disorders are rarely mentioned in the blood type research literature. A French study in the Journal of Diabetes found that, compared with type O blood, type B blood had a 21% higher risk of developing diabetes.
In fact, there is no definite evidence that which blood type is more perfect and has a longer life span. No matter what blood type, maintaining a healthy life is the most important thing.
- To prevent Alzheimer's disease, pay attention after the age of 40
According to the "China Alzheimer's Disease Report 2021", tens of millions of people in China are diagnosed with Alzheimer's disease or other dementias every year. It is 11888. The prevalence rate of women is 9/100,000 higher than that of men.
Niu, director of the Aerobic Exercise Center of Beijing Xiaotangshan Hospital, pointed out that the incubation period of Alzheimer's disease can reach 10-20 years, and the peak period of onset is after the age of 65. Therefore, after the age of 40, we should start to pay attention to Alzheimer's disease and do a good job in related prevention work.
"The Lancet Global Health" once pointed out that if the nine factors are well controlled, nearly 40% of dementia in China may not occur. The nine factors included high blood pressure, diabetes, hearing impairment, depression, social isolation, lack of physical activity, low education, obesity in middle age and smoking in older age. Therefore, we should do our best to pay attention to it and start controlling these risk factors as soon as possible.
Professor Ji Yong, Director of Tianjin Institute of Dementia, pointed out that if the following symptoms appear, you should pay attention to the early signs of some Alzheimer's patients.
The first symptom is memory loss, not remembering details of life. For example, as the disease progresses, the names of relatives, familiar jobs, frequented places, etc. gradually affect the patient's daily life, reduce the quality of life of the patient, may often get lost, have a strange temper, cannot take care of themselves in life, delusions, etc. .
