I found an article that I meant to put up on here but now can't find again, about a study showing how people with TBI's rate their lives before the injury as having been better than a 'healthy' control group.

The implication was that we idealise our lives before the injury, remembering only days when we were rested, alert and felt great. Any tiredness, worry or unusual happenings are likely to be attributed to the brain injury, when in fact they might just be part of normal life.

I think there's some truth in that - we get so used to analysing our every moment for signs of symptoms that we start seeing more than there actually are and then getting anxious about it....
