We investigated the relationship between cortical cerebral blood flow (cortical rCBF) or Crossed Cerebellar Diaschisis (CCD) and recovery after stroke in 20 hémiplégie subjects, unable to walk and dependent on the ADL 3 months after a single stroke in the territory of the middle cerebral artery. At the entry into the study and 6 months after stroke, patients underwent complete neurological and functional and SPECT scanning (with 99TcHM-PAO as a tracer). Patients who recovered gait and ADL abilities showed an higher early cortical rCBF than patient who did no recover. However cortical rCBF remained unchanged over time. There was no differences in the cerebellar hemisphere asymmetry index between the two groups of patients, suggesting that early cortical rCBF, but not CCD, is a prognostic indicator of recovery after stroke.
