BOLD fMRI signal in stroke patients and its importance for prognosis in the subacute disease period – Preliminary report

Conclusion There are differences observed in the activation areas of the cerebral cortex both in the stroke and non-stroke hemispheres of the brain in stroke patients. More than half of the patients with hemispheric stroke but all with good outcome showed cerebellar activation. There was no clear correlation between the cortical activation pattern and the neurological status on the first day of stroke. There is probable positive correlation between the size of BOLD-signal in fMRI, young age, activation of supplementary motor area in stroke hemisphere and good functional status of patients in the subacute period of stroke.
