Comparative Study
Alteration in polysomnographic profile in 'migraine without aura' compared to healthy controls.
Studies related to sleep macroarchitecture in migraines are far and few between. We studied the polysomnographic (PSG) abnormalities in subjects of 'migraine without aura' as compared to healthy controls. ⋯ This study showed significantly lower sleep efficiency, prolonged sleep onset latency, lesser stage 4 and NREM sleep, and more number of total awakenings in migraineurs compared to the controls. Further studies are required to detect whether these abnormalities are due to migraine per se or associated comorbidities.

The aims for this study were to determine the prevalence of sleep-bruxism among young children, explore child behavior problems that may be associated with sleep-bruxism, and identify relations among sleep-bruxism, health problems, and neurocognitive performance. ⋯ The prevalence of sleep-bruxism was high. A dynamic and potentially clinically relevant relation exists among sleep-bruxism, internalizing behaviors, health, and neurocognition. Pediatric sleep-bruxism may serve as a sentinel marker for possible adverse health conditions, and signal a need for early intervention. These results support the need for an interdisciplinary approach to pediatric sleep medicine, dentistry, and psychology.

To assess the characteristics of obstructive sleep apnea (OSA) patients with nightmares and the effects of continuous positive airway pressure (CPAP) therapy on nightmares. ⋯ Nightmares in OSA patients are associated with a higher REM-AHI. CPAP therapy results in a significant improvement in nightmare occurrence.

Rapid eye movement (REM) sleep behavior disorder (RBD) may be a risk factor for dementia development in patients with Parkinson's disease (PD); however, the role of subclinical RBD remains unknown. Patients with PD and clinical RBD, subclinical RBD, or with normal REM sleep were examined in a cross sectional study and a longitudinal follow-up. ⋯ Clinical RBD symptoms, but not subclinical RBD, were associated with the development of dementia in PD.

This is a video case report of a 58-year-old male patient with severe obstructive sleep apnea (OSA) who underwent a pharyngo-laryngoscopy during non-drug-induced sleep. ⋯ This case highlights that OSA could not be as obstructive as generally thought, at least during N2 sleep; moreover, it suggests that apneic episodes are not a totally passive and monomorphic phenomenon, but a rather complex event.
