When we are talking about your health, there are some factors that are modifiable and some are not. One of those such non-modifiable factors is your blood group. Your blood group or your blood type, is actually something that you inherit from your parents and it is determined on the basis of some microscopic substances living on the surface of the red blood cells. You can feel that they have nothing to do with your health but that is actually not so true. These substances can interact with your immune system in some unique way, and therefore affect your risk of certain diseases. In dependance of your blood type, A, B, AB, or O, you are at a higher or lower risk of some diseases.
Memory
Study showed that people with AB blood type are more prone to cognitive
impairment. As one study from University of Vermont found out, 82%
people with this blood type are more likely to develop thinking problems
that may eventually turn into dementia. And according to yet another
study, some older people with AB blood type, found it difficult to
remember and recall things as compared to the others.
