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 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 ...
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 ...
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 ...
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 ...
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: ...
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 ...
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 ...
Does age matter? A mixed methods study examining determinants of good recovery and resilience in young and middle-aged adults following moderate-to-severe traumatic brain injury
Recovery and resilience after TBI
Aim: To examine whether age contributes to functional recovery and resilience after moderate-to-severe traumatic brain injury (TBI). Background: The ability to recover from TBI may change across the lifespan, but the ...
Association between waking electroencephalography and cognitive event-related potentials in patients with obstructive sleep apnea
EEG and ERP in OSA
Objective: Abnormal event-related potentials (ERP) and slowing of the waking electroencephalographic (EEG) activity have been reported in patients with obstructive sleep apneas (OSA). This study aimed at evaluating whether ...
