  • 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 ...

    Daneault, Véronique; Hébert, Marc; Albouy, Geneviève; Doyon, Julien; Dumont, Marie; Carrier, Julie; Vandewalle, Gilles (Oxford University Press, 2014-01-01)
    Study Objectives: Light exposure, particularly blue light, is being recognized as a potent mean to stimulate alertness and cognition in young individuals. Aging is associated with changes in alertness regulation and cognition. Whether the effect of ...

  • Are age and sex effects on sleep slow waves only a matter of EEG amplitude ? 

    Rosinvil, Thaïna; Bouvier, Justin; Dubé, Jonathan; Lafrenière, Alexandre; Bouchard, Maude; Cyr-Cronier, Jessica; Nadia, Gosselin; Carrier, Julie; Lina, Jean-Marc (Oxford University Press, 2020-09-15)
    Aging is associated with reduced slow wave (SW) density (number SW/min in nonrapid-eye movement sleep) and amplitude. It has been proposed that an age-related decrease in SW density may be due to a reduction in electroencephalogram (EEG) amplitude ...

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

    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 ...

    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 ...

  • Cerebral white matter diffusion properties and free‐water with obstructive sleep apnea severity in older adults 

    Baril, Andrée‐Ann; Gagnon, Katia; Descoteaux, Maxime; Bedetti, Christophe; Chami, Sirin; Sanchez, Erlan; Montplaisir, Jacques-Yves; De Beaumont, Louis; Gilbert, Danielle; Poirier, Judes; Pelleieux, Sandra; Osorio, Ricardo S.; Carrier, Julie; Gosselin, Nadia (Wiley, 2020-03-13)
    Characterizing the effects of obstructive sleep apnea (OSA) on the aging brain could be key in our understanding of neurodegeneration in this population. Our objective was to assess white matter properties in newly diagnosed and untreated adults with ...

    Bouchard, Maude; Lina, Jean-Marc; Gaudreault, Pierre-Olivier; Dubé, Jonathan; Gosselin, Nadia; Carrier, Julie (American academy of sleep medicine, 2019-11-06)
    Study Objectives In young adults, sleep is associated with important changes in cerebral connectivity during the first cycle of non-rapid eye movement (NREM) sleep. Our study aimed to evaluate how electroencephalography (EEG) connectivity during sleep ...

  • Effects of menopause on sleep quality and sleep disorders : Canadian longitudinal study on aging 

    Zolfaghari, Sheida; Yao, Chun; Thompson, Cynthia; Gosselin, Nadia; Desautels, Alex; Dang-Vu, Thien Thanh; Postuma, Ronald B.; Carrier, Julie (Lippincott, Williams & Wilkins, 2020-02-29)
    OBJECTIVES:Sleep complaints are common during the menopause transition. However, it is difficult to disentangle changes in sleep related to aging from those directly due to menopause. We compared sleep disorders in 45 to 60-year-old women in a large ...

  • 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 and the risk of cognitive decline in older adults 

    Gosselin, Nadia; Baril, Andrée-Ann; Osorio, Ricardo S.; Kaminska, Marta; Carrier, Julie (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 and function. Recent cohort ...

  • 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 ...

    Lafrenière, Alexandre; Lina, Jean-Marc; Hernandez, Jimmy; Bouchard, Maude; Gosselin, Nadia; Carrier, Julie (Oxford University Press, 2022-10-11)
    The sleep slow-wave (SW) transition between negative and positive phases is thought to mirror synaptic strength and likely depends on brain health. This transition shows signifcant age-related changes but has not been investigated in pathological ...
