Gray matter hypertrophy and thickening with obstructive sleep apnea in middle-aged and older adults
Gray matter increases with obstructive sleep apnea
(American Thoracic Society, 2017-06-01)
Rationale: Obstructive sleep apnea causes intermittent hypoxemia, hemodynamic fluctuations, and sleep fragmentation, all of which could damage cerebral gray matter that can be indirectly assessed with neuroimaging. Objectives: ...
Obstructive sleep apnea and the risk of cognitive decline in older adults
(American Thoracic Society, 2019-01-15)
Obstructive sleep apnea causes intermittent hypoxia and sleep fragmentation and affects at least 20% of individuals after the age of 65. There is accumulating evidence that obstructive sleep apnea may impact brain structure ...
A longitudinal investigation of sleep and daytime wakefulness in children and youth with concussion
A high proportion of adults who sustain a concussion identify changes in their sleep during the acute stage, typically reporting an increased need for sleep or nonrestful sleep. Our understanding of sleep following ...
The impact of poor sleep on cognition and activities of daily living after traumatic brain injury : a review
Sleep and everyday activities after TBI
Background/aim : Patients frequently report sleep disrup-tions or insomnia during their hospital stay, particularlyafter a traumatic brain injury (TBI). The consequences ofthese sleep disturbances on everyday activities ...
Brain white matter damage and its association with neuronal synchrony during sleep
(Oxford University Press, 2019-01-28)
The restorative function of sleep partly relies on its ability to deeply synchronize cerebral networks to create large slow oscillations observable with EEG. However, whether a brain can properly synchronize and produce a ...
Evolution of severe sleep-wake cycle disturbances following traumatic brain injury: a case study in both acute and subacute phases post-injury
Background. Sleep-wake disturbances are frequently reported following traumatic brain injury (TBI), but they remain poorly documented in the acute stage of injury. Little is known about their origin and evolution. Case ...
Obstructive sleep apnea during REM sleep and daytime cerebral functioning : a regional cerebral blood flow study using high-resolution SPECT
Obstructive sleep apnea (OSA) predominantly during rapid eye movement (REM) sleep may have impacts on brain health, even in milder OSA cases. Here, we evaluated whether REM sleep OSA is associated with abnormal daytime ...
Parallel recovery of consciousness and sleep in acute traumatic brain injury
(American Academy of Neurology, 2017)
Objective: To investigate whether the progressive recuperation of consciousness was associated with the reconsolidation of sleep and wake states in hospitalized patients with acute traumatic brain injury (TBI). Methods: ...
Visual fixation in the intensive care unit: a strong predictor of post-traumatic amnesia and long-term recovery after moderate-to-severe traumatic brain injury
Visual fixation in the ICU
(Lippincott, Williams & Wilkins, 2016-12-01)
Objective: We examined whether visual fixation at 24h of intensive care unit (ICU) admission is superior to the initial Glasgow Coma Scale (GCS) score to predict PTA duration and long-term TBI recovery. Design: Two-phase ...
Sleep in the acute phase of severe traumatic brain injury : a snapshot of polysomnography
Sleep and traumatic brain injury
Background and Objectives. The onset of pervasive sleep-wake disturbances associated with traumatic brain injury (TBI) is poorly understood. This study aimed to (a) determine the feasibility of using polysomnography in ...
