OBJECTIVE: Vasomotor symptoms (VMS) may be associated with an increased risk of cardiovascular disease. One candidate mechanism may involve alterations in physiological responses to stress. The current study therefore examined the relationship between self-reported VMS bother and cardiovascular, hemodynamic, neuroendocrine, and inflammatory responses to an acute psychosocial stress protocol. METHODS: One hundred eighty-six women in the menopausal transition or early postmenopausal stage (age 45-60 y) provided the data for this article...

BACKGROUND: Butylphthalide sodium chloride injection for patients with acute cerebral infarction has a certain effect. Although there are several proposed mechanisms of drug action, no related research on improving the inflammatory cytokines that regulate the body's immune system through the hypothalamus-pituitary-adrenal axis has been published. OBJECTIVE: To determine the impact of butylphthalide and sodium chloride injection on the hypothalamus-pituitary-adrenal (HPA) axis after acute cerebral infarction in the basal ganglia...

BACKGROUND: Despite high quality stroke care, decreased sensorimotor function, anxiety and pain often remain one year after stroke which can lead to impaired health and dependence, as well as higher healthcare costs. Touch massage (TM) has been proven to decrease anxiety and pain, and improve quality of health in other conditions of reduced health, where reduced anxiety seems to be the most pronounced benefit. Thus there are reasons to believe that TM may also reduce anxiety and pain, and improve quality of life after stroke...

INTRODUCTION: Acute ischemic stroke is a stressful condition where there is marked increase in the production of cortisol. In the past, adrenal insufficiency in critically ill patients had been shown to be associated with significant morbidity and mortality. To date, there have been no studies performed to determine its prevalence among patients with acute ischemic stroke.  OBJECTIVES: The aim of this study was to determine the prevalence of relative adrenal insufficiency in acute ischemic stroke by utilizing low dose (LD) and standard dose (SD) synacthen tests and to correlate it with inpatient hospital morbidity and mortality...

BACKGROUND: Stroke leads to transient immunedepression, which leads to increased incidence of poststroke infections. Because infection is one of the most common causes of increased mortality in patients with stroke, this study was undertaken to document immunedepression after stroke in our population. METHODS: A case-controlled study wherein 39 patients with acute ischemic stroke in the age group of 18 and 60 years without any evidence of previous immunedepression were included...

INTRODUCTION: Traumatic brain injury (TBI), subarachnoid hemorrhage (SAH), stroke and cerebrovascular disease (CVD) are identified as risk factors for hypopituitarism. Pituitary dysfunction after TBI, SAH, and CVD may present in the acute phase or later in the course of the event. Chronic hypopituitarism, particularly growth hormone (GH) deficiency is related to the increased cardiovascular morbidity and mortality. In patients with serious ventricular arrhythmias, who need cardiopulmonary resuscitation, brain tissue is exposed to short-term severe ischemia and hypoxia...

BACKGROUND AND PURPOSE: The level of stress hormones, especially cortisol reflects stroke severity and acts as an early risk assessment of the severity of disease and prognosis. There are few neuroendocrine change and prognostic value data in patients with spontaneous supratentorial intracerebral hemorrhage (ICH). The present study aimed to evaluate the prognostic value of cortisol in patients with acute ICH. METHODS: In a prospective observational study including 61 consecutive patients with supratentorial ICH, the morning (8 a...

There are multiple definitions of stress. For this review, as a reference point, we will use the concept of acute emotional/psychosocial stress ("stress"). The presence of acute stress has been reported to have a significant effect on seizure control, with several studies showing patients with seizure disorders being able to predict with reasonable accuracy seizure occurrence within the following hours or days. However, neuroimaging investigations of the pathophysiological mechanisms underlying stress reactivity (e...

Studies in non-stroke patients have shown an association between dysregulation of the hypothalamic-pituitary-adrenal axis and morbidity and mortality. We conducted a systematic review to evaluate cortisol levels in acute stroke and their associations with outcome. We searched MEDLINE and EMBASE for articles up to April 2013 and PsychINFO for articles up to July 2013, using the keywords "cortisol" and "stroke" and associated terms or synonyms. We included studies published in peer-reviewed journals that recruited 10 or more participants and measured cortisol at least once in the first year following stroke...

BACKGROUND: Post-stroke immune depression contributes to the development of infections which are major complications after stroke. Previous experimental and clinical studies suggested that humoral stress mediators induce immune dysfunction. However, prospective clinical studies testing this concept are missing and no data exists for other cerebrovascular diseases including intracerebral hemorrhage (ICH) and TIA. METHODS: We performed a prospective clinical study investigating 166 patients with TIA, ischemic and hemorrhagic stroke...

BACKGROUND: Early prediction of outcome is important for allocation of therapeutic strategies. Endocrine alterations of the hypothalamus-pituitary-axis are one of the first stress-induced alterations after cerebral ischemia. We therefore evaluated the prognostic value of serum cortisol in Chinese patients with an acute ischemic stroke. METHODS: In a prospective observational study, serum cortisol was measured using a solid-phase, competitive chemiluminescent enzyme immunoassay on admission in serum of 226 consecutive Chinese patients with an acute ischemic stroke...

Acute brain ischemia caused by transient ischemic attack initiates a complex sequence of events in the central nervous system and hypothalamic-pituitary-adrenal (HPA) axis which may ultimately culminate in neuronal and cell damage. The brain is highly susceptible to ischemia and in response to stress shows changes in morphology and chemistry that are largely reversible. These responses are known to modify the function of the HPA axis, but their mechanisms are not yet clear. Duration and size of the HPA axis activation are regulated by corticotropin-releasing hormone, vasopressin (AVP), and glucocorticoids, including cortisol...

OBJECTIVES: The authors have tried to assess the noise annoyance and its relation with the development of hypertension for the staff working at the civilian airport of Algiers. This population is constantly subject to aircraft noises. The noise, through creating stress, acts on the central nervous system and on the autonomic nervous system and is likely to cause hypertension by increasing peripheral resistance, total cholesterol, fatty acids, adrenaline, cortisol and blood glucose. A number of studies revealed that starting from 65 decibels, the noise causes hypertension for patients of more than 40 years following 5 years of exposure...

Inflammation and activation of the neuroendocrine systems comprise important aspects of stroke pathophysiology. The present study investigated whether baseline plasma brain natriuretic peptide (BNP), N-terminal pro-brain natriuretic peptide (NT-proBNP), cortisol and copeptin levels on admission can predict short-term outcomes and mortality after acute ischaemic stroke. The study group consisted of 189 patients who had their first acute ischaemic stroke. Plasma levels of BNP, NT-proBNP, cortisol and copeptin were evaluated to determine their value with respect to predicting functional outcome and mortality within 3 months...

BACKGROUND AND PURPOSE: Acute stroke has a high morbidity and mortality. We evaluated the predictive value of adrenal function testing in acute ischemic stroke. METHODS: In a cohort of 231 acute ischemic stroke patients, we measured dehydroepiandrosterone (DHEA), DHEA-Sulfate (DHEAS), cortisol at baseline and 30 minutes after stimulation with 1 ug ACTH. Delta cortisol, the amount of rise in the 1 ug ACTH-test, was calculated. Primary endpoint was poor functional outcome defined as modified Rankin scale 3-6 after 1 year...

In contrast to heavy alcohol consumption, which is harmful, light to moderate drinking has been linked to reduced cardiovascular morbidity and mortality. Effects on lipid status or clotting do not fully explain these benefits. Exaggerated cardiovascular responses to mental stress are detrimental to cardiovascular health. We hypothesized that habitual alcohol consumption might reduce these responses, with potential benefits. Advanced magnetic resonance techniques were used to accurately measure cardiovascular responses to an acute mental stressor (Montreal Imaging Stress Task) in 88 healthy adults (∼1:1 male:female)...

Hyperglycemia is common after acute stroke. In the acute phase of stroke (within 24h), rats with permanent cerebral ischemia developed higher fasting blood glucose and insulin levels in association with up-regulation of hepatic gluconeogenic gene expression, including phosphoenolpyruvate carboxykinase, glucose-6-phosphatase, and fructose-1,6-bisphosphatase. In addition, hepatic gluconeogenesis-associated positive regulators, such as FoxO1, CAATT/enhancer-binding proteins (C/EBPs), and cAMP responsive element-binding protein (CREB), were up-regulated...

Karoshi, death from over-work, is usually the extreme result of acute cardiovascular events including stroke. Among 203 karoshi cases received worker compensation in Japan, sixty percent died of stroke. Karoshi is a term for social medicine originated form Japan. Literature reviews on karoshi found that long overtime at work, on duty in holidays, attending a new job with no family members around, and working at night shift are risk factors. Work stress increases secretion of catecholamines (epinephrine and norepinephrine) and cortisol which is associated with progression of atherosclerosis and increased risk of cardiovascular diseases and stroke...
