Mazerolle M, Kimoff R, Khadadah S, Duquette P, Jobin V, Lapierre Y, et al.
Mult Scler Relat Disord . 2023 Nov; 81:105144. PMID: 38007963
Background: Obstructive sleep apnea-hypopnea (OSAH) is common in MS patients and is associated with fatigue. We recently published a randomized, controlled trial (RCT) of active vs sham continuous positive airway...

Dev Cogn Neurosci . 2023 Mar; 60:101232. PMID: 36963244
Although many studies of the adolescent brain identified positive associations between cognitive abilities and cortical thickness, little is known about mechanisms underlying such brain-behavior relationships. With experience-induced plasticity playing an...

Khadadah S, Kimoff R, Duquette P, Jobin V, Lapierre Y, Benedetti A, et al.
Mult Scler . 2021 Apr; 28(1):82-92. PMID: 33890515
Objective: The aim of this study was to evaluate the effect of continuous positive airway pressure (CPAP) treatment on the Fatigue Severity Scale (FSS, preplanned primary outcome), another fatigue measure,...

Syme C, Pelletier S, Shin J, Abrahamowicz M, Leonard G, Perron M, et al.
Int J Obes (Lond) . 2018 Sep; 43(6):1223-1230. PMID: 30206338
Objective: Life-long maintenance of brain health is important for the prevention of cognitive impairment in older age. Low-grade peripheral inflammation associated with excess visceral fat (VF) may influence brain structure...

Marchand-Krynski M, Belanger A, Morin-Moncet O, Beauchamp M, Leonard G
Dev Neuropsychol . 2018 May; 43(5):430-453. PMID: 29764201
This study examined cognitive predictors of sequential motor skills in 215 children with dyslexia and/or attention deficit/hyperactivity disorder (ADHD). Visual working memory and math fluency abilities contributed significantly to performance...

Shin J, French L, Xu T, Leonard G, Perron M, Pike G, et al.
Cereb Cortex . 2017 Oct; 28(9):3267-3277. PMID: 28968835
Neurobiological underpinnings of cortical thickness in the human brain are largely unknown. Here we use cell-type-specific gene markers to evaluate the contribution of 9 neural cell-types in explaining inter-regional variations...

Parker N, Wong A, Leonard G, Perron M, Pike B, Richer L, et al.
Sci Rep . 2017 Aug; 7(1):7397. PMID: 28784996
Income inequality is associated with poor health and social outcomes. Negative social comparisons and competition may involve the hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes in underlying some of these complex...

Mult Scler J Exp Transl Clin . 2017 Jun; 3(1):2055217317690561. PMID: 28607750
Background: Multiple sclerosis (MS) patients have central nervous system (CNS) lesions that may impede cognitive and sensorimotor function. Few rehabilitative therapies are available. Objectives: The objective of this paper is...

PLoS One . 2017 May; 12(5):e0177490. PMID: 28542319
Dyslexia and Attention deficit disorder (AD) are prevalent neurodevelopmental conditions in children and adolescents. They have high comorbidity rates and have both been associated with motor difficulties. Little is known,...

Wong A, French L, Leonard G, Perron M, Pike G, Richer L, et al.
Cereb Cortex . 2017 Mar; 28(4):1272-1281. PMID: 28334178
Age-related decreases in cortical thickness observed during adolescence may be related to fluctuations in sex and stress hormones. We examine this possibility by relating inter-regional variations in age-related cortical thinning...
