Stroke Causes: Blood group tells about many diseases related to a person in advance. Let us tell you how the risk of stroke is linked to the blood group and which people are most likely to suffer from stroke.

Stroke Symptoms: A person's blood type can predict the risk of a stroke. This is evidenced by numerous studies. A report published in the journal Neurology revealed a link between blood type and early stroke risk. Research suggests that people with blood type A, also known as A1, are at increased risk of stroke before the age of 60. Let us explain when this risk occurs for people with other blood types and what research has revealed.

What did the research reveal?

Published in the journal Neurology, this research included approximately 48 genetic studies, involving 17,000 people who had experienced a stroke and 600,000 who had not. All participants were between the ages of 18 and 59. Through genome-wide studies, scientists identified genetic loci associated with early stroke risk. One of these was associated with blood type. Further study revealed that those with the A1 blood subgroup have a 16 percent increased risk of stroke compared to other blood types. However, the reasons behind this are still unclear. Research suggests that blood type A1 may affect clotting factors or other mechanisms, which may increase the risk of stroke.

What did the expert say?

Study co-principal investigator Steven J. Kittner, MD, MPH, professor of neurology at the University of Maryland School of Medicine (UMSOM) and neurologist at the University of Maryland Medical Center, said, "The number of people experiencing strokes is increasing. These individuals are more likely to die from this life-threatening event, and those who survive may experience disability for decades. Despite this, there has been very little research on the causes of strokes." Studies like this one make it more likely that genetics, including blood type, plays a role in increasing or decreasing the risk of stroke, especially at a young age. Researchers hope this information will help identify at-risk individuals earlier and lead to more targeted prevention strategies in the future.
