We investigated abnormalities of the hypothalamic-pituitary-gonadal axis and cortisol concentrations in women with fibromyalgia and chronic fatigue syndrome (CFS) who were in the follicular phase of their menstrual cycle, and whether their scores for depressive symptoms were related to levels of these hormones. A total of 176 subjects participated - 46 healthy volunteers, 68 patients with fibro...
Objective. To compare salivary cortisol levels of children with ECC and their mothers with those of caries free children from a similar sociodemographic cohort. Design. Sixty-four college-educated, working mothers from middle income families with no history of anxiety disorders and their first born children aged between 48 and 71 months were included in the study. Salivary cortisol levels were ...
BACKGROUND Functional somatic symptoms (FSS), like chronic pain and overtiredness, are often assumed to be stress-related. Altered levels of the stress hormone cortisol could explain the association between stress and somatic complaints. We hypothesized that low cortisol levels after awakening and low cortisol levels during stress are differentially associated with specific FSS. METHODS This ...
Stress-induced changes in cortisol can impact memory in various ways. However, the precise relationship between cortisol and recognition memory is still poorly understood. For instance, there is reason to believe that stress could differentially affect recollection-based memory, which depends on the hippocampus, and familiarity-based recognition, which can be supported by neocortical areas alon...
Neglect and abuse early in life have been associated with increased and decreased cortisol levels, and also with an altered diurnal cortisol slope. In the present study, we investigated the long-term relationship between early maltreatment - at different levels of severity - and basal cortisol secretion in adults adopted as children. A sample of international adoptees was followed from childhoo...
CONTEXT Appropriate glucocorticoid replacement therapy in adrenal insufficiency (AI) is crucial, given the risks of chronic under- or overtreatment, particularly in patients on multiple medications. Salivary sampling allows for non-invasive, stress-free cortisol measurement. OBJECTIVE To determine whether salivary cortisol measurement is helpful in assessing the adequacy of glucocorticoid the...
Cortisol is an important stress hormone affected by a variety of biological and environmental factors, such as the circadian rhythm, exercise and psychological stress. Cortisol is mostly measured using blood or saliva samples. A number of genetic variants have been found to contribute to cortisol levels with these methods. While the effects of several specific single genetic variants is known, ...
Children with antisocial and aggressive behaviors have been found to show abnormal neurobiological responses to stress, specifically impaired cortisol stress reactivity. The role of individual characteristics, such as comorbid anxiety, in the stress response is far less studied. Furthermore, this study extended previous studies in that not only baseline and reactivity to a psychosocial stressor...
CONTEXT There is a central belief that depression is associated with hyperactivity of the hypothalamic-pituitary-adrenal axis, resulting in higher cortisol levels. However, results are inconsistent. OBJECTIVE To examine whether there is an association between depression and various cortisol indicators in a large cohort study. DESIGN, SETTING, AND PARTICIPANTS Data are from 1588 participants...
High cortisol levels are known to cause low fecundity and increased mortality; thus, the prospect of using cortisol as a measure of population health is an exciting one. However, because so many factors can interact to influence cortisol release, it can be difficult to interpret what exactly is creating changes to cortisol levels. This study investigates variation in fecal cortisol levels in a ...
