Blood Vessel Studies Give Insight on Autism Growth

The brain is the control center for the rest of your body, and blood vessels are the foundation of the system. What if your brain vessels didn’t do their jobs? How would that affect the rest of you body? A recent study showed evidence that people with ASD have blood vessels that do not grow and expand like they are meant to.

Professor Efrain C. Azmitia, from New York University, started his research on the postmortem brain of a person with Autism four years ago, and his discoveries have continued to be examined by researchers ever since. He discovered that the blood vessels, which are meant to expand and grow, do not show any growth in the brain of a person who was diagnosed on the autism spectrum. This reflected the conclusion he had from nine other postmortem brains that he looked at, all under the age of 2.

His studies resulted in the conclusion that angiogenesis, the growth of blood vessels in the brain, does not occur the proper way in the brain of a person with Autism. This also lead to a claim that people on the autism spectrum do not have the growth of their blood vessels checked as they get older.

University of Louisville’s chair of psychiatry, Manuel Casanova, notes that due to the small size of the study, the discovery may not be true for all people with ASD.

Due to a staining tactic of the vessels, Azmitia and his fellow researchers saw that the length of a blood vessel in the brain of a person with autism does not differ from the length of control tissue. This has led the team to focus on studying the possible change of blood vessel diameters for a person with autism.

Keith Young, professor of psychiatry and behavioral science at Texas A&M Health Science Center, believes that the studies stemming from Azmitia’s discovery have come a long way, but they still have several other factors to examine.

“I think that it’s still up in the air whether or not angiogenesis itself might be affected.” Young said.
