Cerebral Hemodynamic Changes in Stroke During Sleep-Disordered Breathing

Stroke.ahajournals.org: June 12, 2012.

Background and Purpose—Sleep-disordered breathing (SDB) negatively impacts stroke outcome. Near-infrared spectroscopy showed the acute cerebral hemodynamic effects of SDB.

Methods—Eleven patients (7 men, age 61±13 years) with acute/subacute middle cerebral artery stroke (National Institutes of Health Stroke Scale score 10±7) and SDB (apnea–hypopnea index 32±28/hour) were assessed with nocturnal polysomnography and bilateral near-infrared spectroscopy recording. Cerebral oxygenation and hemoglobin concentration changes during obstructive and central apneas were analyzed. Read more
