EEG connectivity across sleep cycles and age
(American academy of sleep medicine, 2019-11-06)
Study Objectives
In young adults, sleep is associated with important changes in cerebral connectivity during the first cycle of non-rapid eye movement (NREM) sleep. Our study aimed to evaluate how electroencephalography ...
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 clinical utility of repetitive transcranial magnetic stimulation in reducing the risks of transitioning from acute to chronic pain in traumatically injured patients
(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 ...
Changes in regional cerebral perfusion over time in idiopathic REM sleep behavior disorder
(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 ...
Validity of actigraphy for nighttime sleep monitoring in hospitalized patients with traumatic injuries
(American academy of sleep medicine, 2020-02-15)
Study objectives: Sleep-wake disturbances are frequent among patients hospitalized for traumatic injuries but remain poorly documented due to the lack of tools validated for hospitalized patients. This study aimed to ...
Cerebral white matter diffusion properties and free‐water with obstructive sleep apnea severity in older adults
(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 ...
Waking EEG functional connectivity in middle-aged and older adults with obstructive sleep apnea
(Elsevier, 2020-06-14)
Objectives: The present study aimed at investigating changes in waking electroencephalography
(EEG), most specifically regarding spectral power and functional connectivity, in middle-aged and
older adults with OSA. We ...
Obstructive sleep apnea and the risk of cognitive decline in older adults
(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 ...
Gray matter hypertrophy and thickening with obstructive sleep apnea in middle-aged and older adults
Gray matter increases with obstructive sleep apnea
(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: ...
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 ...
