  • Actigraphy data in pediatric research : the role of sleep diaries 

    Actigraphy and sleep diary
    Tétreault, Émilie; Bélanger, Marie-Ève; Bernier, Annie; Carrier, Julie (Elsevier, 2018-01)
    Background. When assessing children's sleep using actigraphy, researchers usually rely on a sleep diary completed by a parent as an aid in scoring actigraphic data. However, parental nonadherence in completing the sleep diary may significantly reduce ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Normative developmental trajectories of actigraphic sleep variables during the preschool period : a three-wave longitudinal study 

    Preschool sleep trajectories
    Tétreault, Émilie; Bernier, Annie; Matte‐Gagné, Célia; Carrier, Julie (Wiley, 2018-02)
    Important changes in sleep are believed to occur in the preschool years, but studies that have documented these changes were generally cross‐sectional or based on subjective sleep measures. The current longitudinal study modeled the developmental ...
  • Objective and subjective measures of sleep among preschoolers: Disentangling attachment security and dependency 

    Attachment and sleep among toddlers: disentangling attachment security and dependency.
    Bélanger, Marie-Ève; Bernier, Annie; Simard, Valérie; Bordeleau, Stéphanie; Carrier, Julie (2015-03)
    Many scholars have proposed that parent-child attachment security should favor child sleep. Research has yet, however, to provide convincing support for this hypothesis. The current study used objective measures of sleep and attachment to assess the ...
  • 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 ...
  • 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 ...
  • Sleeping Toward Behavioral Regulation: Relations Between Sleep and Externalizing Symptoms in Toddlers and Preschoolers 

    Bélanger, Marie-Ève; Bernier, Annie; Simard, Valérie; Desrosiers, Kim; Carrier, Julie (2015-11-25)
    Objective: The aim of this study was to investigate the concurrent and longitudinal relations between sleep and externalizing symptoms among young children. Method: Sixty-four families (mostly Caucasian; 36 boys) were met twice, when children were ...
  • 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 ...
