Sleep Macrostructure, Cyclic Alternating Pattern and CSF Cytokines in De Novo Relapsing–Remitting Multiple Sclerosis: A Controlled Polysomnographic Study

Journal of Sleep Research, EarlyView.
ABSTRACT Multiple sclerosis is frequently associated with sleep disorders. This study aimed to evaluate subjective and objective sleep parameters in de novo relapsing–remitting multiple sclerosis patients compared to healthy controls and to explore correlations with cerebrospinal fluid cytokines.

Neurometabolic Response to Apneic Stimuli Tracks Global Grey Matter Volume Deficits in Patients With Obstructive Sleep Apnea

Journal of Sleep Research, EarlyView.
ABSTRACT Obstructive sleep apnea (OSA) has been linked to cortical atrophy and increased risk of neurodegeneration, a process potentially mediated by neurometabolic dysregulation. Recent work using high temporal‐resolution metabolic MRI found greater changes in the cerebral metabolic rate of oxygen consumption (CMRO2) during cued breath‐hold stimuli ...

Validation of OSLER Test Against Maintenance of Wakefulness Test and the Association With Subjective Measures of Sleepiness

Journal of Sleep Research, EarlyView.
ABSTRACT The ability to stay awake is crucial in life and can be compromised by insufficient sleep and medical conditions. Measuring alertness is important for evaluating driving ability and the Oxford Sleep Resistance (OSLER) test may provide an easy way for assessment.
