Sleep-disordered breathing and stroke

Abstract

Sleep and stroke have an important and fascinating interaction. Patients with sleep-disordered breathing present with cardiovascular heart disease, cognitive decline, and increased risk of stroke. Stroke adversely affects sleep and factors such as prolonged immobilization, chronic pain, nocturnal hypoxia, and depression, which can also adversely impact sleep quality. Obstructive sleep apnea (OSA), one of the most common and serious sleep disturbances, manifests itself in almost 50% of all stroke patients. Sleep apnea patients who experience a stroke may be at a greater impairment in their rehabilitation potential and have increased risk of secondary stroke and mortality. Given these factors, the practicing neurologist should possess the skills to appropriately recognize, rapidly diagnose, and properly manage stroke patients with OSA. © 2008 MedReviews®, LLC.
