    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 ...

    High angular resolution diffusion imaging (HARDI)-based tractography has been increasingly used in longitudinal studies on white matter macro- and micro-structural changes in the language network during language acquisition and in language impairments. ...
  • 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 ...
