Introduction:
We report the changes in cortical activity evaluated using functional near-infrared spectroscopy (fNIRS) in 2 cases with cerebellar stroke.
Methods:
Using an fNIRS imaging system, changes in the oxygenated hemoglobin concentration (ΔOxy-Hb) from baseline were estimated. Design and verbal fluency tasks were conducted for evaluation of visuospatial and language functions, respectively.
Results:
The contralateral prefrontal area showed limited activation compared with the ipsilateral one in the case with either cerebellar stroke.
Conclusions:
A negative impact of cerebellar stroke on the multimodal association of cortex, regardless of the type of stroke (infarct or hemorrhage).
