Measuring Cognitive Fatigue After TBI

Research Update: Measuring Cognitive Fatigue After TBI

A brief summary of current research.

The neural correlates of cognitive fatigue in traumatic brain injury using functional MRI

Kohl, AD, Wylie, GR, Genova, HM, Hillary, FG, DeLuca, J Brain Injury, Volume 23, Issue 5 May 2009, pp 420 – 432.

This study used functional magnetic resonance imaging (fMRI) to objectively assess cognitive fatigue in people with TBI. When performing a cognitive task, the participants with TBI showed increased brain activity over time, compared to the non-injured participants. This increased activity in various parts of the brain, which indicates increased cerebral "effort," might manifest as an individual’s feeling of cognitive fatigue.

I had a traumatic brain injury 6 years ago. I'm 98% back to normal apart from fatigue. All my syptoms seem to come back if I don't rest. Over the years I've managed to shift work loads and family around a daily hour rest from 2pm till 3pm. This rest help see me through the rest of the day without feeling utterly rubbish. It is a pain in days out or occasions.I also find if I do too much even with a sleep I have a relapse and old syptoms come back. This is a rain check for me to tell me to slow down.

I'm 5 years out from my TBI. 'Neuro-fatigue' rules my life. I'm unable to teach and had to end my 15 year career. I've had doctors, neurologists, have no knowledge of what this is. Talk about feeling hopeless. My neuropsychologist gets this and helps me with strategies.
