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 ... -
The clinical utility of repetitive transcranial magnetic stimulation in reducing the risks of transitioning from acute to chronic pain in traumatically injured patients
Jodoin, Marianne; Rouleau, Dominique; Larson-Dupuis, Camille; Gosselin, Nadia; De Beaumont, Louis (Elsevier, 2017-07-08)Pain is a multifaceted condition and a major ongoing challenge for healthcare professionals having to treat patients in whom pain put them at risk of developing other conditions. Significant efforts have been invested in both clinical and research ... -
Electrophysiological impact of multiple concussions in asymptomatic athletes: a re-analysis based on alpha activity during a visual-spatial attention task
Guay, Samuel; De Beaumont, Louis; Drisdelle, Brandi Lee; Lina, Jean-Marc; Jolicoeur, Pierre (2017-11-22)Most EEG studies used event-related potentials to assess long-term and cumulative effects of sport-related concussions on brain activity. Time-frequency methods provide another approach that allows the detection of subtle shifts in types and patterns ... -
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 ... -
Investigating the incidence and magnitude of heterotopic ossification with and without joints involvement in patients with a limb fracture and mild traumatic brain injury
Jodoin, Marianne; Rouleau, Dominique; Therrien, Erik; Chauny, Jean-Marc; Sandman, Emilie; Larson-Dupuis, Camille; Leduc, Stéphane; Gosselin, Nadia; De Beaumont, Louis (Elsevier, 2019-08-13)Objectives: This study seeks to evaluate the incidence rate of heterotopic ossification (HO) formation in patients afflicted by an isolated limb fracture (ILF) and a concomitant mild traumatic brain injury (mTBI). Methods: The current study is an ... -
Moderate to severe acute pain disturbs motor cortex intracortical inhibition and facilitation in orthopedic trauma patients : a TMS study
Jodoin, Marianne; Rouleau, Dominique; Bellemare, Audrey; Provost, Catherine; Larson-Dupuis, Camille; Sandman, Emilie; Laflamme, Georges-Yves; Benoit, Benoit; Leduc, Stéphane; Levesque, Martine; Gosselin, Nadia; De Beaumont, Louis (Public library of science, 2020-03-20)Objective Primary motor (M1) cortical excitability alterations are involved in the development and maintenance of chronic pain. Less is known about M1-cortical excitability implications in the acute phase of an orthopedic trauma. This study aims to ... -
Parallel recovery of consciousness and sleep in acute traumatic brain injury
Duclos, Catherine; Dumont, Marie; Arbour, Caroline; Paquet, Jean; Blais, Hélène; Menon, David K.; De Beaumont, Louis; Bernard, Francis; Gosselin, Nadia (American Academy of Neurology, 2017)Objective: To investigate whether the progressive recuperation of consciousness was associated with the reconsolidation of sleep and wake states in hospitalized patients with acute traumatic brain injury (TBI). Methods: This study comprised 30 ...
