  • Are NREM sleep characteristics associated to subjective sleep complaints after mild traumatic brain injury? 

    Sleep after mild TBI
    Arbour, Caroline; Khoury, Samar; Lavigne, Gilles; Gagnon, Katia; Gaétan, Poirier; Montplaisir, Jacques-Yves; Carrier, Julie; Gosselin, Nadia (Elsevier, 2015-04)
    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 including electroencephalography ...
  • Association between waking electroencephalography and cognitive event-related potentials in patients with obstructive sleep apnea 

    EEG and ERP in OSA
    Baril, Andrée-Ann; Gagnon, Katia; Gagnon, Jean-François; Montplaisir, Jacques-Yves; Gosselin, Nadia (Elsevier, 2013)
    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 an association exists between ...
  • Biomarkers of dementia in obstructive sleep apnea. 

    Baril, Andrée-Ann; Carrier, Julie; Lafrenière, Alexandre; Warby, Simon; Poirier, Judes; Osorio, Ricardo S.; Ayas, Najib; Dubé, Marie-Pierre; Petit, Dominique; Gosselin, Nadia; Canadian Sleep and Circadian Network (Elsevier, 2018-08-13)
    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 sleep apnea may significantly ...
  • Brain white matter damage and its association with neuronal synchrony during sleep 

    Sanchez, Erlan; El-Khatib, Héjar; Arbour, Caroline; Bedetti, Christophe; Blais, Hélène; Marcotte, Karine; Baril, Andrée-Ann; Descoteaux, Maxime; Gilbert, Danielle; Carrier, Julie; Gosselin, Nadia (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 restorative sleep when it ...
  • 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
    Arbour, Caroline; Gosselin, Nadia; Levert, Marie‐Josée; Gauvin-Lepage, Jérôme; Michallet, Bernard; Lefebvre, Hélène (Wiley, 2017-07-05)
    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 influence of age on TBI outcome ...
  • Gray matter hypertrophy and thickening with obstructive sleep apnea in middle-aged and older adults 

    Gray matter increases with obstructive sleep apnea
    Baril, Andrée-Ann; Gagnon, Katia; Brayet, Pauline; Montplaisir, Jacques-Yves; De Beaumont, Louis; Carrier, Julie; Lafond, Chantal; L’Heureux, Francis; Gagnon, Jean-François; Gosselin, Nadia (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: To investigate whether ...
  • A longitudinal investigation of sleep and daytime wakefulness in children and youth with concussion 

    Wiseman-Hakes, Catherine; Gosselin, Nadia; Sharma, Bhanu; Langer, Laura; Gagnon, Isabelle (SAGE, 2019-01-10)
    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 concussion is less well understood ...
  • Obstructive sleep apnea during REM sleep and daytime cerebral functioning : a regional cerebral blood flow study using high-resolution SPECT 

    Baril, Andrée-Ann; Gagnon, Katia; Brayet, Pauline; Montplaisir, Jacques-Yves; Carrier, Julie; Soucy, Jean-Paul; Lafond, Chantal; Blais, Hélène; d’Aragon, Caroline; Gagnon, Jean-François; Gosselin, Nadia (SAGE, 2018-11-22)
    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 cerebral functioning using ...
  • Regional cerebral blood flow during wakeful rest in older subjects with mild to severe obstructive sleep apnea 

    Cerebral perfusion in OSA
    Baril, Andrée-Ann; Gagnon, Katia; Arbour, Caroline; Soucy, Jean-Paul; Montplaisir, Jacques-Yves; Gagnon, Jean-François; Gosselin, Nadia (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 that predict altered ...
  • Sleep in the acute phase of severe traumatic brain injury : a snapshot of polysomnography 

    Sleep and traumatic brain injury
    Wiseman-Hakes, Catherine; Duclos, Catherine; Blais, Hélène; Dumont, Marie; Bernard, Francis; Desautels, Alex; Menon, David K.; Gilbert, Danielle; Carrier, Julie; Gosselin, Nadia (SAGE, 2015-12-23)
    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 patients in the acute, hospitalized ...
  • Towards a better understanding of increased sleep duration in the chronic phase of moderate to severe traumatic brain injury : an actigraphy study 

    El-Khatib, Héjar; Arbour, Caroline; Sanchez, Erlan; Dumont, Marie; Duclos, Catherine; Blais, Hélène; Carrier, Julie; Gosselin, Nadia (Elsevier, 2018-11-28)
    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 by TBI-related characteristics ...
  • 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
    Caroline, Arbour; Baril, Andrée-Ann; Westwick, Harrison J.; Potvin, Marie-Julie; Gilbert, Danielle; Giguère, Jean-François; Lavigne, Gilles; Desautels, Alex; Bernard, Francis; Laureys, Steven; Gosselin, Nadia (Lippincott, Williams & Wilkins, 2016-12-01)
