Sleep and aggressive behavior among toddlers: investigating directionality of associations
Sleep and aggression in toddlers
(Wayne State University Press, 2018)This study examined the reciprocal associations between sleep (duration and quality) and aggressive behavior in toddlers. The sample consisted of 82 children (43 boys and 39 girls) and their parents who completed two assessments, when children were 2 ... -
Sleep and wake disturbances following traumatic brain injury
(Elsevier, 2014-10)Traumatic brain injury (TBI) is a major health concern in industrialised countries. Sleep and wake disturbances are among the most persistent and disabling sequelae after TBI. Yet, despite the widespread complaints of post-TBI sleep and wake disturbances, ... -
Sleep in the acute phase of severe traumatic brain injury : a snapshot of polysomnography
Sleep and traumatic brain injury
(SAGE, 2015-12-23)Background and Objectives. The onset of pervasive sleep-wake disturbances associated with traumatic brain injury (TBI) is poorly understood. This study aimed to (a) determine the feasibility of using polysomnography in patients in the acute, hospitalized ... -
Sleep oscillation-specific associations with Alzheimer’s disease CSF biomarkers : novel roles for sleep spindles and tau
(BMC, 2019-02-21)Background: Based on associations between sleep spindles, cognition, and sleep-dependent memory processing, here we evaluated potential relationships between levels of CSF Aβ42, P-tau, and T-tau with sleep spindle density and other biophysical ... -
Sleep slow waves’ negative-to-positive-phase transition : a marker of cognitive and apneic status in aging
(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 ... -
Sleep spindles are resilient to extensive white matter deterioration
(Oxford University Press, 2020-06-13)Sleep spindles are an essential part of non-rapid eye movement sleep, notably involved in sleep consolidation, cognition, learning and memory. These oscillatory waves depend on an interaction loop between the thalamus and the cortex, which relies on ... -
Sleep-wake disturbances in hospitalized patients with traumatic brain injury: association with brain trauma but not with an abnormal melatonin circadian rhythm
(Oxford University Press, 2019-09-28)Study Objectives: To test whether the sleep-wake cycle disruption in patients hospitalized with traumatic brain injury (TBI) 1) is also found in patients with traumatic injuries other than TBI (nonTBI); and 2) is associated to a weaker or abnormal ... -
Sleeping Toward Behavioral Regulation: Relations Between Sleep and Externalizing Symptoms in Toddlers and Preschoolers
(2015-11-25)Objective: The aim of this study was to investigate the concurrent and longitudinal relations between sleep and externalizing symptoms among young children. Method: Sixty-four families (mostly Caucasian; 36 boys) were met twice, when children were ... -
Smartphone use as an efficient tool to improve anomia in primary progressive aphasia
(Taylor and Francis, 2023-03-05)Cognitive interventions are helpful in the non-pharmacologicalmanagement of Primary progressive aphasia (PPA) and otherneurodegenerative disorders of cognition, by helpingpatients to compensate for their cognitive deficits andimprove their functional ... -
Spatial learners display enhanced oculomotor performance
(Routledge, 2018-09-21)Attention is important during navigation processes that rely on a cognitive map, as spatial relationships between environmental landmarks need to be selected, encoded, and learned. Spatial learners navigate using this process of cognitive map formation, ... -
Stability in maternal autonomy support and child executive functioning
(2015-09)The purpose of this study was to examine the role of early and current maternal autonomy support, and of its stability over time, in predicting child executive functioning (EF). Seventy-eight mother–child dyads participated in two visits when children ... -
Subcortical amyloid load is associated with shape and volume in cognitively normal individuals
Subcortical Aβ associates to morphometry
(Wiley, 2019-05-21)Amyloid-beta (Aβ) deposition is one of the main hallmarks of Alzheimer’s disease. The study assessed the associations between cortical and subcortical 11C-Pittsburgh Compound B retention, namely in the hippocampus, amygdala, putamen, caudate, pallidum, ... -
Subcortical amyloid relates to cortical morphology in cognitively normal individuals
(Springer, 2019-07-25)Purpose Amyloid (Aβ) brain deposition can occur in cognitively normal individuals and is associated with cortical volume abnormalities. Aβ-related volume changes are inconsistent across studies. Since volume is composed of surface area and thickness, ... -
Task-induced functional connectivity of picture naming in healthy aging : the impacts of age and task complexity
(MIT Press, 2020-06-01)The topological organization of the brain, governed by the capacity of brain regions to synchronize their activity, allows for cost-effective performance during everyday cognitive activity. Functional connectivity is an fMRI method deemed task-specific ... -
Test-retest reliability of diffusion measures extracted along white matter language fiber bundles using HARDI-based tractography
(Frontiers media, 2019-01-14)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. ... -
To say or not to say : dyadic ambivalence over emotional expression and its associations with pain, sexuality, and distress in couples coping with provoked vestibulodynia
(2014-05)Introduction Provoked vestibulodynia (PVD) is a highly prevalent and taxing female genital pain condition. Despite the intimate nature of this pain and the fact that affective factors such as anxiety have been shown to modulate its manifestations, ... -
Towards a better understanding of increased sleep duration in the chronic phase of moderate to severe traumatic brain injury : an actigraphy study
(Elsevier, 2018-11-28)Introduction Most adults with moderate to severe traumatic brain injury (TBI) report persistent sleep-wake disturbances. Whether these complaints are either associated with abnormal sleep-wake patterns or can be explained by TBI-related characteristics ... -
Towards an integrated understanding of aggression in the general population : findings from an epidemiological catchment area study
Aggression in the general population
(Elsevier, 2019-03-23)The goal of this study is to identify patterns of various forms of aggression in the general population and their psychosocial and environmental correlates. Data from the Montreal Epidemiological Catchment Area study (N = 1855) were analyzed using ... -
