Yesterday, I had an incident wherein my hairdresser pretty aggressively rubbed my scalp, to the extent that I was quite noticeably dizzy and light-headed afterward-- probably the closest thing I've had thus far to an actual re-injury. No headache or exhaustion, thankfully.

My question is this: Obviously I need to minimize these kinds of incidents, but do they constitute a full-on re-injury? The reason I ask is that one reads constantly about the fact that a second or third TBI dramatically increases the risk of dementia in old age. I feel like I need to live in a bubble until I can withstand a vigorous scalp massage... :-(
