What I said, is the recovery may appear to be 100% but when under stress, symptoms can appear. This has been well studied. This does not mean that a person with PCS can't return to their previous life, just that they may experience a reoccurred of symptoms during times of stress.

The simplest example of this is once concussed, the brain will be more sensitive to the next concussion. This shows a residual injury/limitation. This is a well known issue.

The study looked at cognitive performance without stress and when under stress and found those with a concussion history showed a statistical reduction in cognitive performance when under stress yet those without a concussion history did not suffer this level of cognitive performance decline when under stress.

Although not as comprehensive, a study using qEEG was able to show that 97% of those with a concussion history showed residual symptoms.

As I have always said, There can be an appearance of a 100% recovery. One expert has challenged the medical community to record any possibility of a concussion on medical records so that symptoms that show up later can be properly understood.

What is so hard to understand about this issue ?
