Most of us are aware that chronic trauma to the head can cause CTE (Chronic Traumatic Encephalopathy) Later this can lead to long term neurological problems such as Alzheimer’s and Parkinson’s diseases as well as ALS (Amyotrophic Lateral Sclerosis). For some time it was thought that CTE resulted from repetitive concussions,
Recently researchers from Boston University published a study in the journal Brain reported that non-concussive repetitive hits to the can lead to CTE. In other words you do not necessarily need to have had severe concussions to develop CTE.
Researchers at Stanford are working on projects that should lead to a better understanding of the effect on the brain of blunt trauma. It appears as though injury seems to occur when an area in the brain, the corpus callous, shakes more rapidly and intensely than surrounding parts of the brain,
This insight eventually will change the way that manufacturers design protective headgear for football and other sports. The researchers need to validate their findings but brain research is complicated and time consuming. I have no doubt that within a reasonable period of time there will be protective helmets that are much more effective in preventing CTE and its complications.
