Background: Chronic cerebral hypoperfusion (CCH) causes white matter damage and cognitive impairment, in which astrogliosis is the major pathology. However, underlying cellular mechanisms are not well defined. Activation of Na+/H+ exchanger-1 (NHE1) in reactive astrocytes causes astrocytic hypertrophy and swelling. In this study, we

Cerebral hypoperfusion that causes neurologic def-icits lasting 24 hours is invariably associated with infarction on brain imaging. We present the case of a patient with persistent aphasia that fluctuated over 1 week, left middle cerebral artery (MCA) stenosis, and hypoperfusion of the left MCA territory documented

Cerebral hypoperfusion in OI can be related to hypocapnia which causes cerebral vasocon- striction and reduces cerebral blood flow. This mechanism, e.g. hypocapnic cerebral hypoper-

In some, a relatively small fall in blood pressure may induce cerebral hypoperfusion, especially in the presence of cerebro-vascular disease. A variety of symptoms result from hypoperfusion of other organs.

Cerebral hypoperfusion induced by bilateral common carotid artery occlusion (BCCAo) in rodents has been proposed as an experimental model of white matter damage and vascular dementia. However, the histopathological and behavioral alterations reported in this model are variable and a full characterization of the dynamic alterations is not available.

Background: Chronic cerebral hypoperfusion causes damage to the brain’s white matter underpinning vascular cognitive impairment. Inflammation and oxidative stress have been proposed as key pathophysiological mechanisms of which the transcription factor Nrf2 is a master regulator. We hypothesised that white matter

lying pathophysiology is poorly understood. This study describes orthostatic cerebral hypoperfusion syndrome (OCHOs). OCHOs is defined by (1) abnormal orthostatic drop of cerebral blood flow velocity (CBFv) during the tilt test and (2) absence of orthostatic hypotension, arrhythmia, vascular abnormalities, or other causes of abnormal ortho-
