Although I wish they’d have gone into detail about the possible cause of cognitive fatigue (in patients with TBI), it’s still an interesting study.
Essentially, cognitive fatigue is one of the most challenging symptoms of TBI and they’ve had problems measuring it really accurately until they started using function MRI. Basically, when they studied people with TBI and people without it doing the same behavioral tasks, the ones with TBI showed increased brain activity – which means their brains were working harder.
Now that they can see this, they will start looking for the best methods to train the brains of people with TBI (and stroke, MS, etc.) Then they can do more fMRIs to confirm what’s working.
