Great advances have been made in our understanding of Takotsubo syndrome in the past decade, but the aetiology of the condition remains incompletely understood. The most established theory, that catecholamine-mediated myocardial stunning is provoked by emotional or physiological stress, is supported by the presence of supraphysiological levels of plasma catecholamines in patients with Takotsubo syndrome. For this reason, the hyperexcitability of the autonomic nervous system under conditions of physical and emotional stress is often assessed in these patients...

Anecdotally, we all know that stress is 'complicated', although most stress research is undertaken using incredibly simplified models that may not allow us to fully understand the underlying interactive mechanisms present in the 'real world'. This attempt at simplification, although sometimes necessary, may explain some of the difficulties faced when integrating basic science findings with the clinical and epidemiological data on stress and stress-related disorders. In a symposium held at the 2015 International Society for Psychoneuroendocrinology meeting in Edinburgh, UK, a series of speakers explored 'The Many Pathways to Plasticity in the Stress System', specifically focusing on variables that, in many cases, are eliminated from studies of stress to provide increased experimental control...

BACKGROUND/PURPOSE: The short- and long-term impacts of behavioral and psychological factors on the diabetes and cognitive function relationship are not fully understood. This study examined levels and rates of change in age trajectories of cognitive function in middle-aged and older adults with and without diabetes who participated in different health behaviors. METHODS: Participants aged 53 and above with and without diabetes were drawn from the 1999 Taiwan Longitudinal Study of Aging (N = 4076, mean age 69...

Salivary alpha-amylase (sAA) is a stress-sensitive biomarker the shows promise as an indirect proxy of sympathetic-adrenal-medullary axis activities that are otherwise difficult to discern non-invasively. This comprehensive study investigated diurnal sAA in association with numerous psychosocial characteristics related to mental health, work stress, and non-work stress. Participants included 395 workers (56.1% women, age: M=41.3, SD=10.81) from across 34 distinct workplaces. Diurnal sAA was sampled over two non-consecutive work days at awakening, 30 min after awakening, 14h00, 16h00, and bedtime...

Visceral pain is a term describing pain originating from the internal organs of the body and is a common feature of many disorders, including irritable bowel syndrome (IBS). Stress is implicated in the development and exacerbation of many visceral pain disorders. Recent evidence suggests that stress and the gut microbiota can interact through complementary or opposing factors to influence visceral nociceptive behaviours. The Young Investigator Forum at the International Society of Psychoneuroendocrinology (ISPNE) annual meeting reported experimental evidence suggesting the gut microbiota can affect the stress response to affect visceral pain...

The cortisol awakening response (CAR), the marked increase in cortisol secretion over the first 30-45 min after morning awakening, has been related to a wide range of psychosocial, physical and mental health parameters, making it a key variable for psychoneuroendocrinological research. The CAR is typically assessed from self-collection of saliva samples within the domestic setting. While this confers ecological validity, it lacks direct researcher oversight which can be problematic as the validity of CAR measurement critically relies on participants closely following a timed sampling schedule, beginning with the moment of awakening...

In its current form, the Département de psychiatrie at the Université de Montréal (UdeM) was created in 1964. The first person to have headed was Dr. Gerard Beaudoin… Between 1948 and 1964, several others psychiatrists were heading the Département without necessary bearing a particular title.The directors of the Département from 1951 to now were: Drs. Fernand Côté, Camille Laurin, Gerard Beaudoin, Yvon Gauthier, Arthur Amyot, Francis Borgeat, Hugues Cormier, Sylvain Palardy, Jean Hébert, and Emmanuel Stip...

The role of stress in the origin and development of depression may be conceived as the result of multiple converging factors, including the chronic effect of environmental stressors and the long-lasting effects of stressful experiences during childhood, all of which may induce persistent hyperactivity of the hypothalamic-pituitary-adrenal axis. These changes, including increased availability of corticotropin-releasing factor and cortisol, are also associated with hyperactivity of the amygdala, hypoactivity of the hippocampus, and decreased serotonergic neurotransmission, which together result in increased vulnerability to stress...

Moderate physical activity improves various cognitive functions, particularly when it is applied simultaneously to the cognitive task. In two psychoneuroendocrinological within-subject experiments, we investigated whether very low-intensity motor activity, i.e. walking, during foreign-language vocabulary encoding improves subsequent recall compared to encoding during physical rest. Furthermore, we examined the kinetics of brain-derived neurotrophic factor (BDNF) in serum and salivary cortisol. Previous research has associated both substances with memory performance...

Knowledge about children's stress reactivity and its correlates is mostly based on one stress task, making it hard to assess the generalizability of the results. The development of an additional stress paradigm for children, that also limits stress exposure and test time, could greatly advance this field of research. Research in adults may provide a starting point for the development of such an additional stress paradigm, as changes in salivary cortisol and alpha-amylase (sAA) over a 1-h pre-stress period in the laboratory correlated strongly with subsequent reactivity to stress task (Balodis et al...

Previous research has revealed an acute 8-fold increase in salivary cortisol following self-administrated Ecstasy/MDMA in dance clubbers. It is currently not known to what extent repeated usage impacts upon activity of the hypothalamic-pituitary-adrenal axis over a more prolonged period of time. This study investigated the integrated cortisol levels in 3-month hair samples from recent Ecstasy/MDMA users and non-user controls. One hundred and one unpaid participants (53 males, 48 females; mean age 21.75 years) completed the University of East London recreational drug use questionnaire, modified to cover the past 3-months of usage...

The olfactory system is an essential part of human physiology, with a rich evolutionary history. Although humans are less dependent on chemosensory input than are other mammals (Niimura 2009, Hum. Genomics 4:107-118), olfactory function still plays a critical role in health and behavior. The detection of hazards in the environment, generating feelings of pleasure, promoting adequate nutrition, influencing sexuality, and maintenance of mood are described roles of the olfactory system, while other novel functions are being elucidated...

Several studies have shown that a woman's vaginal or axillary odors convey information on her attractivity. Yet, whether such scents induce psychoneuroendocrinological changes in perceivers is still controversial. We studied if smelling axillary and vulvar odors collected in the periovulatory and late luteal phases of young women modify salivary testosterone and cortisol levels, as well as sexual desire in men. Forty-five women and 115 men, all of them college students and unacquainted with each other, participated in the study...

In this review we summarize the results and conclusions of five studies as presented in a symposium at the 42nd annual meeting of the International Society for Psychoneuroendocrinology, in New York in September 2012. Oxytocin administration has received increasing attention for its role in promoting positive social behavior and stress regulation, and its potential as a therapeutic intervention for addressing various aspects of psychiatric disorders. However, it has been noted that the observed effects are not uniformly beneficial...
