Former NHL goaltender Tim Thomas said Thursday that his post-concussion syndrome symptoms were so severe that he couldn’t make basic decisions and his brain wasn’t functioning well enough to even watch hockey.

In his first public appearance since walking away from the game, Thomas said a scan taken after he retired showed that two-thirds of his brain were getting less than 5% blood flow and the other third was getting less than 50%.

The 45-year-old said it took significant time and help to even be able to communicate with former teammates and others.

He’s still not close to normal.
