My theory of fatigue after stroke

I have read in several sources that our brain uses 15-20% of the energy of our body to work. And while thinking hard it may use up to 50%. So based on that I would speculate that as we recover our brain is probably using 90% all day long. Even at night it is probably working hard. Then throw in working your good side twice as much as normal and your affected side being incredibly inefficient. Being cardiovascularily fit doesn't seem to help. Three years after my stroke during a physical my resting heart rate was 54 at age 53, looking at my fitness level that meant I was an athlete.
That does not help my fatigue at all and I doubt I could get any fitter.

If your doctor has a better explanation please comment about it.
