    No need to repeat that 'fatigue' can be hard to describe and even harder to demonstrate objectively.

    A new blog on health rising suggests that deterioration in rapid eye movements (aka saccades where both eyes move rapidly to scan or fixate on a target) may objectively demonstrate increasing fatigue in healthy controls and a range of conditions (including breast cancer survivors) :

    Interestingly a ME/CFS specific study found some impairment in saccades but marked impairment in tracking a smoothly moving target (smooth pursuit) :

    It would be good if we could piggyback on fatigue research in other areas.

    This is one of the papers linked in Cort Johnson's article.
