Minimac,

There are many reasons for tau protein to malfunction in the brain. Researchers are looking at those with excessive levels of these malfunctions and trying to find ways to reduce them. There is not as much opportunity to investigate the early/lesser accumulations of these defective tau proteins. Tau proteins are an important part of neurological function but it is when they become defective and get tangled that they are a problem.

Due to the prevalence of Alzheimer's Disease, the research is going strong with opes of finding ways to prevent these defects. Hopefully, the treatment will be affordable for the masses.

Getting worried about Tau proteins and CTE can be counter productive. The best solution is to use a good brain supplement regimen and stay mentally active. And, reduce stress in your life.
