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: ...
Are age and sex effects on sleep slow waves only a matter of EEG amplitude ?
(Oxford University Press, 2020-09-15)
Aging is associated with reduced slow wave (SW) density (number SW/min in nonrapid-eye movement sleep) and amplitude.
It has been proposed that an age-related decrease in SW density may be due to a reduction in ...
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 ...
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 ...
Aging reduces the stimulating effect of blue light on cognitive brain functions
(Oxford University Press, 2014-01-01)
Study Objectives:
Light exposure, particularly blue light, is being recognized as a potent mean to stimulate alertness and cognition in young individuals. Aging is associated with changes in alertness regulation and ...
