They explained that in the 495 participants that had cognitive impairment, 6 percent of those had AB blood type.

Mary Cushman of the University of Vermont said the study looks at blood type and risk of cognitive impairment.

She said that their findings show the connection between vascular issues and brain health because blood types are related to other vascular conditions like stroke.

The research also shows that people with type O blood had lower risk of heart disease and stroke. Heart attacks and strokes increase chances of memory loss and dementia.
