In this condition , there is a decrease in functional activity and metabolism in the cerebellum contralateral supratentorial lesion.  This mechanism has been observed in cerebral ischemia patients , supratentorial tumors , epilepsy , encephalitis and some resulting in the disruption of the cortico-ponto-cerebellar pathway.

Functional studies through the use of CT , MRI and CT perfusion help the diagnosis.
