eli5: subconcussive hits relating to CTE question

164 views

A lingering question relating to CTE that I was hoping someone could answer for me is whether there is a difference between getting hit in average day to day life, such as a basketball hitting your head or bumping your head on a door compared to the hits in football. Is it the acceleration and deceleration that is unique to a sport like football? or is it the frequency of any hits like day to day ones? Or is it a combination? Any responses would be helpful

Going for the ELI5 approach.
Your brain is a really just a big puddle of very important Jello floating within the skull in water (CSF). A simple bump on a closed door to the skull doesn’t generate enough force to affect the brain hardly (even repeatedly); whereas, running full speed into really any object head-first is much more likely to have some sequela.

Consider this: Put Jello in a closed container of water and tap the cup against something (even a few times). The Jello isn’t hardly affected. Now, drop the container on the ground. The Jello will likely bounce off the ceiling, then maybe bottom, of the cup (coup/contre-coup). In a similar fashion, the brain can be affected – perhaps just a bit more noticeably with the brain.
