Cortisol levels and seizures in adults with epilepsy: A systematic review
2018
Stress has been suggested as a trigger factor for seizures in epilepsy patients, but little is known about cortisol levels, as indicators of stress, in adults with epilepsy. This systematic review summarizes the evidence on this topic. Following PRISMA guidelines, 38 articles were selected: 14 analyzing basal cortisol levels, eight examining antiepileptic drugs (AEDs) effects, 13 focused on seizure effects, and three examining stress. Higher basal cortisol levels were found in patients than in healthy people in studies with the most homogeneous samples (45% of 38 total studies). Despite heterogeneous results associated with AEDs, seizures were related to increases in cortisol levels in 77% …
Endocrine and mood responses to two working days in female teachers.
2014
AbstractCurrently, a considerable amount of work stress is present in school teachers, one of the occupational groups with the highest levels of job strain and burnout. As chronic stress produces significant modifications in emotional adjustment and neuroendocrine functioning, we aimed to investigate the role of these work stress constructs in the endocrine and mood responses of a group of female teachers during two working days (WD) at different moments in the academic year. We studied mood as well as levels of cortisol and testosterone, representative of a predominant catabolic or anabolic balance. Our results showed that higher “control” was associated with higher positive mood (p = .028…
Reductions in circulating endocannabinoid 2-arachidonoylglycerol levels in healthy human subjects exposed to chronic stressors
2016
Increasing evidence indicates that chronic stress, such as social isolation, plays an important role in the development of a variety of psychiatric and somatic disorders. Meanwhile, chronic stress imposed by prolonged isolation and confinement in the spacecraft is also one of the major concerns for the health of future interplanetary space travelers. Preclinical studies suggest that the peripheral endocannabinoid (eCB) system is involved in the regulation of the stress response and eCB signaling is implicated in the pathogenesis of stress-related diseases. However, there are only few human studies addressing this topic, of which most focusing on patients who have already developed a certain…
Cortisol and trait anxiety as relevant factors involved in memory performance in people with drug-resistant epilepsy
2018
People with drug-resistant epilepsy are exposed to unpredictable and uncontrollable seizures, which can be considered as a chronic stress condition. Additionally, these patients present memory deficits and a high prevalence of depression and anxiety. Cortisol, the main stress hormone, has a modulatory role on memory in healthy individuals and patients with emotional disorders, but its role in memory and emotional processes remains unclear in people with epilepsy. This study analyzes the differences in cortisol levels in people with epilepsy with high and low memory performance, and the relationships among cortisol levels, epilepsy-related factors, memory, anxiety, and depression. Fifty-two …
Blunted Electrodermal and Psychological Response to Acute Stress in Family Caregivers of People with Eating Disorders.
2016
AbstractCaring for an offspring with an eating disorder (ED) is associated with high levels of distress, and health problems. Indeed, ED caregivers have to cope with a range of challenges related to their caring role, which represents a chronic stress situation. This tends to alter body homeostasis and caregivers’ health status. This study aimed to analyse the electrodermal reactivity and psychological response to acute stress in ED caregivers compared to non-caregivers. As expected, caregivers showed lower electrodermal (p < .001, η2partial = .269 for SCL and p < .01, η2partial = .214 for NSCRs) and psychological response (p < .05, η2partial = .198) to acute stress than non-caregi…
Highly resilient coping entails better perceived health, high social support and low morning cortisol levels in parents of children with autism spect…
2013
The negative consequences of caring for people with developmental disabilities have been widely described. However, the ability to bounce back from the stress derived from care situations has been less studied. Those caregivers who have shown this ability are considered as resilient. This study aims to evaluate the relationship between resilience and self-reported health and cortisol awakening response (CAR) in a sample of caregivers of people with autism spectrum disorders (ASD). It also aims to evaluate the role of social support as a mediator in the association between resilience and health. Caregivers with higher resilience show better perceived health, lower morning cortisol levels, an…
The Use of Testosterone/Cortisol Ratio in Response to Acute Stress as an Indicator of Propensity to Anger in Informal Caregivers
2016
AbstractCaring for an offspring diagnosed with a psychological chronic disorder is used in research as a model of chronic stress. Indeed, it is usually associated with disturbances in the salivary cortisol (Csal) levels of the caregiver. An imbalance between salivary testosterone (Tsal) and Csal levels is a marker of proneness to social aggression. Given this, we aimed to establish whether the salivary testosterone/cortisol (Tsal/Csal) ratio response to acute stress could be employed as a marker of proneness to anger in informal caregivers of offspring with autism spectrum (ASD). Tsal/Csal ratio and anger responses to a set of different cognitive tasks as well as anger trait and expression …
Salivary cortisol and immunoglobulin A: responses to stress as predictors of health complaints reported by caregivers of offspring with autistic spec…
2012
In the caregiving model of chronic stress, few studies have been conducted with young middle-aged samples and no data exists about acute stress response in this population. To extend knowledge in this issue, health complaints and psychological, endocrine, and immunological responses to stress have been assessed in a cross-sectional sample of 41 parents of offspring with autistic spectrum disorder (ASD) in comparison with 37 non-caregiver parents. Salivary cortisol and immunoglobulin A (IgA) levels were measured before, during, and after a mental psychosocial stressor, while mood and state anxiety were evaluated before and after the stress. Health complaints, personality traits, socio-econom…
Early detection of the risk of developing psychiatric disorders: a study of 461 Chinese university students under chronic stress
2019
Chronic stress, a characteristic of modern time, has a significant impact on general health. In the context of psychiatric disorders, insufficient coping behavior under chronic stress has been linked to higher rates of (1) depressive symptoms among subjects of the general population, (2) relapse among patients under treatment for clinical depression, and (3) negative symptoms among subjects with an elevated vulnerability to psychosis. In this normative study we assessed basic coping behavior among 461 Chinese freshman university students along with their consumption behavior and general health in terms of regular exercises, physical health, psychosomatic disturbances, and mental health. The…
Reduced cardiovascular activation following chronic stress in caregivers of people with anorexia nervosa.
2017
Caring for offspring diagnosed with eating disorders (EDs) puts caregivers under high levels of chronic stress, which have negative consequences for their health. Unfortunately, caregivers have received little attention from mental health professionals. Chronic stress experienced by informal caregivers has been associated with the alteration of body homeostasis, and therefore, the functioning of various physiological systems. This could be the basis of health problems in informal caregivers of people with EDs. The main objective of this study was to analyze physiological response, in terms of heart rate (HR) and heart rate variability (HRV), to an acute laboratory stressor in a sample of in…
