In my experience, the one issue that stands out about living with PCS or mTBI is over-stimulation. Outsiders have a very difficult time understanding how visual and especially auditory stimulation can overwhelm the person. This sensitivity to over-stimulation effects where I can be and what I can do. It can trigger an outburst or a cognitive shut down.

Voices, especially people talking together and over each other can be a trigger. This can cause the person to need to remove themselves from a social or work environment.

Not everybody has this same struggle but for those who do, it is life changing.
