How Blood Type and Alzheimer’s Risk Are Related

Gray matter in the brain is where important nerve cells are located, including those responsible for storing and processing information. It’s a loss of this gray matter that’s characteristic of Alzheimer’s disease. A new study suggests people with type O blood may have a decreased risk of developing Alzheimer’s or other dementia-related conditions due to an increased amount of gray matter in their brains. Read on to learn more about the research, presented by Boca Raton Home Care Assistance.

Gray Matter and Alzheimer’s

Previous research observed correlations between clinical measures of cognitive decline and a visible loss of gray matter in Alzheimer’s patients. As gray matter decreases, the brain has increased difficulty processing newer information, partly accounting for the short-term memory loss often experienced by seniors with Alzheimer’s.

Gray Matter and Blood Type

The link between grey matter and blood type is based on British study comparing the amount of gray matter in the brains of participants and their risk of developing dementia or Alzheimer’s. The study, involving healthy patients, further separated participants based on their blood type, resulting in the conclusion that people with type O blood may have an added layer of protection against memory impairment.

Why the Difference with Type O?

Researchers based their findings on MRIs to determine if there was a pattern between gray matter and blood type. Results showed less grey matter in the temporal and limbic areas of the brain in participants with A, B and AB blood types. These regions of the brain are often most affected during the early stages of Alzheimer’s. It’s not known exactly why type O people have an advantage, although there is evidence suggesting that blood type affects neurological development early in life, offering one possible explanation.

A previous study on blood type and cognitive impairment found that people with AB blood types were approximately 80 percent more likely to experience cognitive impairment or decline than their type O counterparts. Since O-positive is the most common blood type, this research is welcome news for many people, although there are other risk factors associated with Alzheimer’s that need to considered in addition to blood type.
