PURPOSE: To compare the apnea-hypopnea indices (AHIs) derived using three hypopnea definitions published by the American Academy of Sleep Medicine (AASM) and to determine the impact of the new modifications of the definition on AHIs and the diagnosis of obstructive sleep apnea (OSA)...

Migraine and restless legs syndrome (RLS) are common medical disorders that often co-occur. Various hypotheses have suggested that the co-occurrence of these distinct disorders could be related to shared genetic, neurobiological, or environmental factors...

We aimed to assess the effect of Islamic intermittent fasting, during and outside of Ramadan, on plasma levels of leptin and ghrelin while controlling for several potential confounding variables. Eight healthy male volunteers with a mean age of 26.6±4.9 years reported to the sleep disorders center (SDC) at King Saud University on...

leep-onset and maintenance insomnia is a common symptom in schizophrenic patients regardless of either their medication status (drug-naive or previously treated) or the phase of the clinical course (acute or chronic). Regarding sleep architecture, the majority of studies indicate that non-rapid eye movement (NREM), N3 sleep and...

Background: The signal transducer and activator of transcription 6 (STAT6) transduces signals in response to IL-4 and IL-13 cytokine stimulations, resulting in many cell-specific responses. Some common STAT6 SNPs were associated with asthma predisposition and/or IgE levels, although discrepancies have also been reported...

The circadian clock drives a number of metabolic processes including energy intake, storage and utilization coupled with the sleep/wake cycles. Globally, the increasing prevalence of type 2 diabetes (T2DM) has become a significant international public health concern. In view of the heavy societal burden caused by diabetes,...
