To evaluate the risk and presence of obstructive sleep apnea (OSA) in patients presenting
with acute ischemic stroke, and examine the correlation of OSA with age, sex, ischemic …

Background and Purpose The literature indicates that obstructive sleep apnea (OSA)
increases the risk of ischemic stroke. However, the causal relationship between OSA and …

Objectives The presence of obstructive sleep apnea (OSA) has been found to adversely
affect the neurological recovery after acute ischemic stroke (AIS) in previous observational …

Obstructive sleep apnea (OSA) has been considered as one of the risk factors for ischemic
stroke, but the impact of OSA on wake-up stroke (WUS) is not well studied. We aimed to …

Objectives The onset of ischemic stroke symptoms has been established to have a diurnal
variation, with a sizeable proportion (8–28%) occurring during sleep. Obstructive sleep …

Background: In animal models, brief periods of hypoxemia render the brain tolerant to
subsequent ischemic insults. Sleep apnea leads to frequent episodes of nocturnal …

Background: Wake-up stroke (WUS) are strokes that are noted upon awakening in patients
previously going to bed in a normal state of health. The role of sleep abnormalities in WUS is …

Purpose Obstructive sleep apnea (OSA) is associated with increased risk for stroke, which is
known to further impair respiratory functions. However, it is unknown whether the type and …

Sleep-disordered breathing (SDB) can be a sequela of stroke caused by vascular injury to
vital respiratory centers, cerebral edema, and increased intracranial pressure of space …

Since sleep apnea (SA) and stroke have many shared risk factors an independent
contribution of SA to the overall risk of stroke is not easily proven and has been questioned …
