Are you from O blood group? If yes, then take a sigh of relief as in a new finding researchers have revealed that people with O blood group are more resistant towards the disease Alzheimer when compared to A, B and AB blood groups. According to researchers, O blood group have more grey matter in their brain which protects them against the disease. Alzheimer is an age-related disease usually linked with memory loss, behavioural problems and thinking.
Researchers from the University of Sheffield in collaboration with the IRCCS San Camillo Hospital Foundation in Venice conducted the study. The study is the first of its kind which reveals an interlink between blood types and Alzheimer disease.
For the study, researchers involved 189 participants. Scientists took MRI (Magnetic Resonance Imaging) scans of each participant and calculated the amount of grey matter present the brains along with varying blood group.
After analysing the data, study authors observed that participants with O blood type had more grey matter in the posterior portion of their cerebellum. While people with A, B and AB blood types had smaller grey matter volumes in temporal and limbic regions of the brain, including the left hippocampus, which is one of the earliest part of the brain damaged by Alzheimer’s disease.
Lead author Matteo DeMarco from the University’s Department of Neuroscience explained that volume of grey matter in the brain decreases with the age and larger the grey matter present, lesser the chances of suffering from Alzheimer disease. Thus people with O blood type are at serious advantage here, he added.
However, more research and further tests are required to unravel the mystery behind it and to understand the biological mechanism involved in the phenomenon.
