Obstructive sleep apnea (OSA) is a sleep disorder caused by transient obstruction of the upper airway and results in intermittent hypoxia, sleep fragmentation, sympathetic nervous system activation, and arousal which can have an adverse effect on cardiovascular disease. It is theorized OBJECTIVE
Although several forms of sleep disruption are associated with stroke, few studies have examined the relationship between sleep and histopathologic measures of cerebrovascular disease. We tested the hypothesis that greater sleep fragmentation is associated with a higher burden of cerebral
Epidemiological studies show a positive association between adequate sleep and good health. Further, disrupted sleep may increase the risk for CNS diseases, such as stroke and Alzheimer's disease. However, there has been limited progress in determining how sleep is linked to brain health or how
Obstructive sleep apnea (OSA) has been associated with non-dipping blood pressure (BP). The precise mechanism is still under investigation, but repetitive oxygen desaturation and arousal induced sleep fragmentation are considered the main Impaired vasomotor reactivity of the cerebral vessels on morning awakening has been suggested as one of the mechanisms underlying the predisposition to stroke in the morning. This study investigated cerebrovascular reactivity to hypercapnia on morning awakening and its association with specific
In this study we set out to understand is sleep fragmentation affects the cardiovascular regulation and circadian variability of core body temperature more or less than sleep deprivation. 50 healthy men (age 29.0+/-3.1 years; BMI 24.3+/-2.1 kg/m(2)) participated in a 3-day study that included one

Transcranial magnetic stimulation is a neurostimulation technique which has the potential to serve as a unique research tool for investigating a wide variety of fields in cognitive neuroscience. TMS has been approved by the FDA to serve as a treatment to depression and has also been used to evaluate
OBJECTIVE
Sleep deprivation (SDp) performed before stroke induces an ischemic tolerance state as observed in other forms of preconditioning. As the mechanisms underlying this effect are not well understood, we used DNA oligonucleotide microarray analysis to identify the genes and the gene-pathways
OBJECTIVE
Hourly neurological examinations are frequently performed in the neurointensive care unit (NICU) to quickly detect neurological deterioration. These examinations require the patient to be awakened hourly for days disrupting the sleep cycle and potentially causing neurological deterioration
OBJECTIVE
To examine associations between sleep duration and health outcomes among distinct groups of sexual minority adults.
METHODS
Using data from the 2014 Behavioral Risk Factor Surveillance System, we compared sleep duration (very short: ≤ 5 hr; short: 6 hr; normal: 7-8 hr; and long: ≥ 9 hr per
Background and purpose: Delirium frequently complicates acute stroke and worsens outcomes. Because delirium is potentially preventable, predicting its occurrence is essential. Although several prediction scores have been proposed, nurses need to quickly predict
The translation of neuroprotective agents for ischemic stroke from bench-to-bedside has largely failed to produce improved treatments since the development of tissue plasminogen activator (tPA). One possible reason for lack of translation is the failure to acknowledge the greatest risk factor for
UNASSIGNED
Aircraft noise causes endothelial dysfunction, oxidative stress, and inflammation. Transportation noise increases the incidence of coronary artery disease, hypertension, and stroke. The underlying mechanisms are not well understood. Herein, we investigated effects of phagocyte-type NADPH
