note: notjumping to conclusions here, just hypothesizing
After having some time to soak this in (and sleep), I can't help but shake the feeling that this could be an Andre Waters like situation.
For those who might not know, Andre Waters was a former professional football player who killed himself at the age of 44. Afterwords, an autopsy preformed on his brain revealed that its condition was similar to that of someone twice his age going through the latter stages of ahlzheimer's disease.
Once again, just a theory, not meant to be taken as fact
