CTE usually takes years to develop. If you have been playing hockey for some time and taking hard hits every game, you may be suffering from Multiple Impact Syndrome (your brain has reached its limit of impacts) and/or Cumulative Sub-Concussive Impact Syndrome from a lifetime of hits. My sensitivity has gotten worse as I age and with each successive impact, no matter how light.

My neuro says that likely I have just reached a critical mass of brain impacts.
