  • 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 ...
  • 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 ...
  • Changes in regional cerebral perfusion over time in idiopathic REM sleep behavior disorder 

    Baril, Andrée‐Ann; Gagnon, Jean-François; Pelletier, Amélie; Soucy, Jean-Paul; Gosselin, Nadia; Postuma, Ronald B.; Montplaisir, Jacques-Yves (Wiley, 2020-05-27)
    Background Idiopathic rapid eye movement sleep behavior disorder is associated with increased risk of neurodegeneration, but the temporal evolution of regional perfusion, a marker of cerebral activity, has not been characterized. The objective of the ...
  • 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 ...
  • 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 ...
  • Reduced rapid eye movement sleep in late middle-aged and older apolipoprotein E ɛ4 allele carriers 

    André, Claire; Martineau-Dussault, Marie-Ève; Baril, Andrée-Ann; Marchi, Nicola Andrea; Daneault, Véronique; Lorrain, Dominique; Hudon, Carol; Bastien, Célyne; Petit, Dominique; Thompson, Cynthia; Poirier, Judes; Montplaisir, Jacques-Yves; Gosselin, Nadia; Carrier, Julie (Oxford University Press, 2024-04-18)
    Study Objectives Apolipoprotein E ɛ4 (APOE4) is the strongest genetic risk factor for Alzheimer’s disease (AD). In addition, APOE4 carriers may exhibit sleep disturbances, but conflicting results have been reported, such that there is no clear consensus ...
  • 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 ...
  • REM sleep is associated with the volume of the cholinergic basal forebrain in aMCI individuals 

    André, Claire; Martineau‑Dussault, Marie‑Ève; Daneault, Véronique; Blais, Hélène; Frenette, Sonia; Lorrain, Dominique; Hudon, Carol; Bastien, Célyne; Petit, Dominique; Lafrenière, Alexandre; Thompson, Cynthia; Montplaisir, Jacques-Yves; Gosselin, Nadia; Carrier, Julie (BMC, 2023-09-08)
    Background Rapid-eye movement (REM) sleep highly depends on the activity of cholinergic basal forebrain (BF) neurons and is reduced in Alzheimer’s disease. Here, we investigated the associations between the volume of BF nuclei and REM sleep ...
