The study found that people with AB blood were 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types.
Brain Function and Memory Loss
The ABO gene is connected with brain function and memory loss. People who have blood types A, B, and AB are up to 82 percent more likely to develop cognition and memory problems — which can lead to dementia — compared to those with Type O.
Of this group, researchers found that one particular blood type demonstrated a higher risk for cognitive decline: the type of blood known as AB. Additionally, higher levels of factor VIII- a protein that facilitates clotting of blood- were also correlated with a greater risk of cognitive problems.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
According to the American Heart Association, A, B, and AB blood types are associated with a greater risk of heart attack due to coronary artery disease than type O blood. In particular, people with AB blood appear to have the highest risk.
Chances are higher you'll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this.
O negative is the universal blood type. O negative blood type can only receive O negative blood. O negative donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.

Taken together, the authors concluded that type O and Rh-negative blood groups may be protective against SARS-CoV-2 infection and illness.
Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there's a limited supply of the exact matching blood type. That's because type O negative blood cells don't have antibodies to A, B or Rh antigens.
Dana Devine, shows that people with blood groups A or AB are more likely to have a severe COVID infection than people with blood groups B or O. The study looked at 95 patients critically ill with the SARS-CoV-2 virus in the intensive care units (ICUs) of two major Vancouver hospitals.
We all inherit a copy of some form of APOE from each parent. Those who inherit one copy of APOE-e4 from their mother or father have an increased risk of developing Alzheimer's. Those who inherit two copies from their mother and father have an even higher risk, but not a certainty.
Zaidi et al. reported a positive association between T2DM and the ABO blood group system; T2DM and the ABO blood group system are interrelated on a genetic immunologic basis; however, the study inferred that the individuals with blood groups type B and A have a higher frequency of T2DM [14].
Age. Age is the biggest risk factor for Alzheimer's, as it is for most types of dementia. This means that a person is more likely to get Alzheimer's as they get older. Above the age of 65, a person's risk of developing Alzheimer's doubles about every five years.
Background: Weak blood group A and B phenotypes are correlated with ABO glycosyltransferases exhibiting single-amino-acid changes and/or C-terminal modifications.
People with type O blood are more prone to stomach problems because of the high acidic content in the stomach. So while they can digest protein well, they have to be cautious about consuming too many fats or carbohydrates.
Blood type A is the oldest, and existed even before the human race evolved from our ancestors.
The other blood groups are tens of thousands of years old with B being more recent than A. The oldest group is either group A or one of the forms of group O. Why don't all humans have the same blood type?
Blood type O seems to have the lowest risk. Yet these risks are relative, meaning people with type O blood are not immune to COVID-19. "We do know that people of all types can get infected with COVID-19," says cardiologist Daniel Anderson, MD, PhD.
What Is A Universal Blood Type? In an emergency situation where a patient's blood type is unknown, type O negative blood is the only blood type that is safe to use. The reason is that it is compatible with all blood types. Type O negative is known as the universal blood type.
Brothers and sisters don't always share the same blood type. The genotype of both parents plays a role in defining the blood type. For instance, children of parents with the genotypes AO and BO may have the blood types A, B, AB, or O. Thus, siblings do not necessarily have the same blood type.
Type AB reacted most to nuts and beans, seafood, eggs, and dairy; while A2B also reacted to gluten grains. Type Rh‐negative was most reactive to eggs, dairy, nuts and beans, and gluten grains. The highest IgE scores were among types B and Rh‐negative.
Here's one finding that has continued to surface over the years: People with a non-O blood type (that's A, B, or AB) are at a higher risk of developing cardiovascular diseases.
