Cortical hemodynamics of electrographic status epilepticus in the critically ill

Epilepsia, Volume 66, Issue 3, Page 802-816, March 2025.
Abstract Objectives The pathophysiological mechanisms of status epilepticus (SE) underlying potential brain injury remain largely unclear. This study aims to employ functional near‐infrared spectroscopy (fNIRS) combined with video‐electroencephalography (vEEG) to monitor brain hemodynamics continuously and non‐invasively in critically ill adult ...

Normal electro-oculography in a young Omani male with genetically confirmed best disease complicated by choroidal neovascularization

Oman Journal of Ophthalmology, 2019
Best vitelliform macular dystrophy (VMD) is an autosomal dominant macular dystrophy caused by heterozygous mutations in the bestrophin1 gene. Patients with this condition typically have an abnormal electrooculogram. We report a case of a 16-year-old male

Dynamics of Sleep-Wake Transitions During Sleep

, 2002
We study the dynamics of the awakening during the night for healthy subjects and find that the wake and the sleep periods exhibit completely different behavior: the durations of wake periods are characterized by a scale-free power-law distribution, while

Feasibility and usability of three consecutive nights with self‐applied, home polysomnography

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary In‐laboratory polysomnography, the gold‐standard for diagnosing sleep disorders, is resource‐demanding and not conducive to multiple night evaluations. Ambulatory polysomnography, especially when self‐applied, could be a viable alternative. This study aimed to assess the feasibility and reliability of self‐applied polysomnography over three ...

Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Refuting a Temporal Correlation: Interictal Epileptic Discharges Do Not Preferentially Occur During Respiratory Events in Patients With Sleep‐Related Breathing Disorder and Epilepsy

Journal of Sleep Research, EarlyView.
ABSTRACT The bidirectional interaction between sleep and epilepsy is well known. In particular, it has been established that sleep apnea can worsen epilepsy, whereas sleep apnea (SA) treatment has a beneficial effect on seizure control. However, the exact mechanisms whereby SA promotes epileptic seizures are unknown.
