There is no pharmacological therapy presently available to improve the long-term recovery from acute ischaemic stroke. Either there hasn't yet been a suitable treatment trialled, or the tools for measuring recovery have not been sensitive enough. It is critical therefore to continue to search for robust objective markers of stroke recovery in parallel with the push for drug discovery. Can saccade measures provide such a marker? Dong et al report that in a limited number of mild stroke patients, saccadic parameters that probe cognitive function, especially errors of inhibition during antisaccade and memory-guided paradigms, were abnormal immediately after stroke and improved over time but not to normal.1 These saccade measures appeared …
