If you or someone you love are in the 4 percent of the population with AB blood type, listen up.
A new study published in the journal Neurology, led by Dr. Mary Cushman of the University of Vermont College of Medicine, Burlington, says people with this blood type, the rarest of all blood types, may be more likely to develop memory loss and cognitive issues as they grow older.
The study found people with AB type were 82 percent more likely to develop thinking and memory problems that can lead to the onset of dementia than people with any other type of blood.
More than 30,000 people above the age of 45 were followed during the study for about three years. In those who had no memory or thinking problems at the beginning, the study found 495 participants developed thinking and memory problems, or cognitive issues, during the study. They were compared to 587 people with no cognitive problems.
