Patrick Bellgowan figured he’d made a mistake, when he saw the information. How else to explain it? A researcher at this University of Tulsa’s Laureate Institute for Brain Research was studying the brain of college football players, comparing the outcomes. His attention was on the hippocampus, a shaped region within the brain which plays a role in memory formation and control. Bellgowan knew that the hippocampus was very sensitive to traumatic brain injury. That shrinkage of the area was a hallmark of Alzheimer’s disease. That a decrease in volume corresponded with chronic traumatic encephalopathy, a disease connected boxing together with contact sports.
However, he expected to see little difference in size involving a group of 50 school players and 25 non players because everybody in the study was young and healthful. And to the office of Bellgowan, brought a set of results then Rashimi Singh, a researcher in the Laureate Institute. Are you sure? he said. That cannot be right. The numbers were stark. A group of 25 players without a history of concussions had hippocampuses which were, on average in contrast to those of a control set of 25 men of age and health who didn’t play sports. What’s more, the same brain region in another group of 25 players who’d suffered a minumum of one clinically recognized concussion was, normally, 25 percent smaller in contrast to control group, a bigger difference in volume, Bellgowan says, compared to variants scientists have discovered between the brains of healthful patients and people suffering from Alzheimer’s disease or major depressive disorder.
I cannot tell you how often times we checked this over, Bellgowan states. The effect size was really large. While much of the safety and health debate over football along with other contact sports focuses on the potential risk of developing severe, headline grabbing bronchial diseases such as amyotrophic lateral sclerosis and CTE, an increasing body of evidence indicates that both concussions and sub-concussive strokes can alter mood, cognition and behaviour while causing harm and structural modifications to the brain.
Put simply, contact sports can be worse for your cognitive health than previously assumed, even when you do not finally end up in a dementia ward. Consider: Bellgowan and his co-authors have also found which this longer an athlete had played football, this greater their left hippocampal region was. Football players also scored lower than non human players on tests of cognitive processing speed, and again, soccer career length had an inverse relationship with test outcomes. An international research team detected a microstructural brain harm in concussed male and female school hockey players, harm that cannot be seen with standard .
