We have definitely noticed that movement (when we move him from the bed to the chair) is a HUGE trigger and it takes him a good while to settle down.
He also doesn't like when we say "goodbye" to him and often throws a hissy.
However, they just come; even when nothing is going on so there are times that there is no trigger.. which I don't understand.
I know it has to do with the axonal injury ... but I can't figure out if they are good or not.

How is your life today after the TBI? Are you required to be careful when you do things?! Do you function daily on your own!? How long were you "storming".

I am so sorry to hear you had no family throughout your ordeal.. I can't imagine how frustrating that was, I hope they are there for you now.
