I've learned to cope with many of the changes that I notice 7 months after my mTBI. Some of them are good and I am sure that I do not want to revert back to my pre mTBI way of being in these cases. Some of them disturb and humble me.
One lingering effect is that I tend to shut down when there is too much stimulation. I've always had this tendancy even before my injury, but it's more pronounced now. In the past I could act my way through it - i.e., put on a good show of being in control even when I was feeling overwhelmed. That ability seems to have gone away. I find myself involuntarily "checking out" when there is a combination of bright light, many voices and lots of movement. No matter how hard I try, my brain cannot make sense of it all and I lose the capacity to form intelligent sentences, problem solve and interact with others. It doesn't happen all the time - only when the combo of noise, light and action are intense and constant. It's disturbing and humbling for me when it happens. I'm used to being able to flip a switch in my brain even when I'm on overload that allows me to function. Not anymore. It simply doesn't work.
So if you see me in a noisy, bright, moving crowd and I seem "checked out" I'm not doing it on purpose. I am literally paralyzed.
But I'm still me.
