People belonging to blood group ‘O’ are at lower risk of getting Alzheimeirs : Study

People with an ‘O’ blood type have moregrey matter in their brain, which helps to protect against diseases such as Alzheimer’s, than those with ‘A’, ‘B’ or ‘AB’ blood types, scientists have found.

Researchers at the University of Sheffield in UK found that blood types play a role in the development of the nervous system and may cause a higher risk of developing cognitive decline.

Research fellow Matteo De Marco and Professor Annalena Venneri, from the University’s Department of Neuroscience, made the discovery after analysing the results of 189 Magnetic Resonance Imaging (MRI) scans from healthy volunteers.
