Towards a better understanding of increased sleep duration in the chronic phase of moderate to severe traumatic brain injury : an actigraphy study
Introduction Most adults with moderate to severe traumatic brain injury (TBI) report persistent sleep-wake disturbances. Whether these complaints are either associated with abnormal sleep-wake patterns or can be explained ...
Biomarkers of dementia in obstructive sleep apnea.
Epidemiologic and mechanistic evidence is increasingly supporting the notion that obstructive sleep apnea is a risk factor for dementia. Hence, the identification of patients at risk of cognitive decline due to obstructive ...
Regional cerebral blood flow during wakeful rest in older subjects with mild to severe obstructive sleep apnea
Cerebral perfusion in OSA
(Oxford University Press, 2015)
Objectives: To evaluate changes in regional cerebral blood flow (rCBF) during wakeful rest in older subjects with mild to severe obstructive sleep apnea (OSA) and healthy controls, and to identify markers of OSA severity ...
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 ...
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: ...
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 ...
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 ...
Are NREM sleep characteristics associated to subjective sleep complaints after mild traumatic brain injury?
Sleep after mild TBI
Sleep complaints are common after mild traumatic brain injury (mTBI). While recent find-ings suggest that sleep macro-architecture is preserved in mTBI, features of non-rapid eye movement(NREM) sleep micro-architecture ...
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 ...
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 ...
