Compromised blood-brain barrier competence in remote brain areas in ischemic stroke rats at the chronic stage.

Stroke is a life-threatening disease leading to long-term disability in stroke survivors. Cerebral functional insufficiency in chronic stroke might be due to pathological changes in brain areas remote from the initial ischemic lesion, i.e.

Blood-brain barrier alterations provide evidence of subacute diaschisis in an ischemic stroke rat model.

Background: Comprehensive stroke studies reveal diaschisis, a loss of function due to pathological deficits in brain areas remote from initial ischemic lesion. However, blood-brain barrier (BBB) competence in subacute diaschisis is uncertain. The present study investigated subacute diaschisis in a focal ischemic stroke rat model.
