BACKGROUND: Suicidal ideation (SI) is highly prevalent and a known symptom of Major Depressive Disorder (MDD), but its underlying biological mechanisms are relatively unknown. Several studies linked suicidal ideation to dysfunctional brain circuits, specifically fronto-limbic connections. The purpose of this work was to investigate fronto-limbic disconnection in MDD patients with or without SI. METHODS: MDD patients with SI (SI, n=28) or without SI (NSI, n=20), identified by the Scale for Suicide Ideation and healthy controls (HCs, n=30) underwent resting-state functional MRI scanning...

Background: The integrity of the brain histaminergic system is necessary for the unfolding of homeostatic and cognitive processes through the recruitment of alternative circuits with distinct temporal patterns. We recently demonstrated that the fat-sensing lipid mediator oleoylethanolamide indirectly activates histaminergic neurons to exerts its hypophagic effects. The present experiments investigated whether histaminergic neurotransmission is necessary also for the modulation of emotional memory induced by oleoylethanolamide in a contextual fear conditioning paradigm...

EP4 receptor-associated protein (EPRAP) is a newly identified molecule that regulates macrophage activation. We recently demonstrated the presence of EPRAP in the mice brain; however, little is known about the function of EPRAP in this tissue. Therefore, we investigated the role of EPRAP in behavior and emotion using behavioral analysis in mice. In this study, we subjected EPRAP-deficient (KO) mice and wild-type C57BL/6 (WT) mice to a battery of behavioral tests. EPRAP-KO mice tended to have shorter latencies to fall in the wire hang test, but had normal neuromuscular strength...

Humans often make irrational decisions, especially psychiatric patients who have dysfunctional cognitive and emotional circuitry. Understanding the neural basis of decision-making is therefore essential towards patient management, yet current studies suffer from several limitations. Functional magnetic resonance imaging (fMRI) studies in humans have dominated decision-making neuroscience, but have poor temporal resolution and the blood oxygenation level-dependent signal is only a proxy for neural activity. On the other hand, lesion studies in humans used to infer functionality in decision-making lack characterization of neural activity altogether...

OBJECTIVE: A major terror attack occurred in the Paris region on 13th November 2015. This event was widely showed, described, and commented in the media. Media consumption may lead to a widespread diffusion of trauma-related symptoms following a collective trauma. These effects may depend on the type of media and emotion regulation strategies used by the media consumer. METHOD: Trauma history, traumatic symptoms, media consumption, psychological distress, and emotion regulation strategies of 451 young adults were assessed by an online survey...

BACKGROUND: Hypertension is a risk factor for cerebrovascular disease and cognitive impairment. Women who suffer hypertensive episodes during pregnancy report variable neurocognitive changes within the first decade following the affected pregnancy. However, long-term follow-up of these women into their post-menopausal years has not been conducted. OBJECTIVE: The aim of this study was to examine whether women with a history of preeclampsia were at increased risk of cognitive decline 35-40 years after the affected pregnancy...

Multiple models of aberrant emotional processing in depression have been advanced. However, it is unclear which of these models best applies to emotional disturbances in subclinical depressive symptoms. The current study employed a battery of psychophysiological measures and emotional ratings in a picture-viewing paradigm to examine whether the underarousal, low positive emotion, heightened negative emotion, or emotion context insensitivity model of emotional dysfunction in subclinical depressive symptoms received greatest support...

Research shows that dysfunctional sleep-related cognitions play an important role in the development, maintenance and exacerbation of insomnia. This study examines the factorial validity, psychometric properties and both concurrent and predictive validity of the German version of the 16-item DBAS (dysfunctional beliefs and attitudes about sleep) scale. Data was collected in 864 vocational students from the German-speaking part of Switzerland (43% females, M age = 17.9 years). Data collection took place twice within a 10-month interval...

BACKGROUND: Numerous experiments in rodents suggest a causative link between exposure to general anaesthetics during brain growth spurt and poor long-lasting neurological outcomes. Many of these studies have been questioned with regard of their translational value, mainly because of extremely long anaesthesia exposure. Therefore, the aim of the present study was to assess the impact of a short sevoflurane anaesthesia, alone or combined with clonidine treatment, on respiratory function in spontaneously breathing rat pups and overall effects on long-lasting emotional and cognitive functions...

BACKGROUND: Takotsubo Cardiomyopathy (TTC) is a transient disorder of ventricular wall dysfunction, mostly induced by physical or emotional stress. TTC may be associated with adverse cardiac events. The association of cancer and its clinical impact in TTC patients has not been described yet. METHODS: In 114 consecutive patients presenting with TTC between January 2003 and September 2015, we studied the frequency of cancer diagnosis, and compared the clinical course and the occurrence of a clinical endpoint of cancer and non-cancer patients during a follow up of 4...

PURPOSE: This study presented the construct of Work-Health Balance (WHB) and the design and validation of the Work-Health Balance Questionnaire (WHBq). More and more workers have a long-standing health problem or disability (LSHPD). The management of health needs and work demands is crucial for the quality of working life and work retention of these workers. However, no instrument exists measuring this process. The WHBq assesses key factors in the process of adjusting between health needs and work demands...

Psychopathic traits are a manifestation of a personality pathology that comprises a core affective-interpersonal dysfunction (callous-unemotional traits) and an impulsive-antisocial behavioral component. Of particular importance, psychopathic traits are associated with the perpetration of some of the most severe acts of violence, and they appear to indicate a subset of youth at risk for earlier onset, greater frequency, and persistence of violent offending. Although these youth represent a minority of the population, they commit a significant proportion of the violence in the general community...

BACKGROUND: Cortical and subcortical cognitive impairments have been found in dementia with Lewy bodies (DLB). Roughly, they comprise visuoconstructive and executive dysfunction, whereas memory would remain relatively spared. However, the cognitive profile of patients with prodromal DLB remains poorly illustrated to date. METHODS: We included 37 patients with prodromal DLB (age 67.2 ± 8.6 years, 18 men, Mini Mental State Examination [MMSE] score 27.4 ± 2) and 29 healthy control subjects (HCs; age 68...

BACKGROUND: The prevalence of erectile dysfunction among diabetic men varies between 35-90%. Although erectile dysfunction is widespread among men with diabetes, the condition often remains undiagnosed and demands appropriate assessment and prompt treatment. Erectile dysfunction can affect all aspects of a patient's life including physical, emotional, social, sexual, and relationships. The main aim of this study is to determine the prevalence and determinants of erectile dysfunction among diabetic patients attending hospitals in the Central and Northwest zone of Tigray, Ethiopia...

Testosterone treatment increases sexual desire and well-being in women with hypoactive sexual desire disorder; however, many studies have shown only modest benefits limited to moderate doses. Unlike men, available data indicate women show a bell-shaped dose-response curve for testosterone, wherein a threshold dosage of testosterone leads to desirable sexual function effects, but exceeding this threshold results in a lack of further positive sexual effects or may have a negative impact. Emotional and physical side-effects of excess testosterone, including aggression and virilization, may counteract the modest benefits on sexual interaction, providing a possible explanation for a threshold dose of testosterone in women...

BACKGROUND: Generalized anxiety disorder (GAD) and social anxiety disorder (SAD) are co-morbid and associated with similar neural disruptions during emotion regulation. In contrast, the lack of optimism examined here may be specific to GAD and could prove an important biomarker for that disorder. METHOD: Unmedicated individuals with GAD (n = 18) and age-, intelligence quotient- and gender-matched SAD (n = 18) and healthy (n = 18) comparison individuals were scanned while contemplating likelihoods of high- and low-impact negative (e...

INTRODUCTION: Emotion recognition, a social cognition domain, is impaired in people with schizophrenia and contributes to social dysfunction. Whether impaired emotion recognition emerges as a manifestation of illness or predates symptoms is unclear. Findings from studies of emotion recognition impairments in first-degree relatives of people with schizophrenia are mixed and, to our knowledge, no studies have investigated the link between emotion recognition and social functioning in that population...

OBJECTIVE: Emotional and cognitive disturbances are common complications in Parkinson's disease (PD). N400 is an event related potential (ERP) strongly linked to lexical-semantic processing and has demonstrated alterations in amplitude and latency when PD patients performed semantic priming tasks. The present study investigated the role of N400 in an automatic affective priming paradigm in PD. Other ERP components relevant to emotion processing were also examined. METHOD: Twenty-two PD patients and 17 healthy adults performed an automatic affective priming task while ERPs were recorded using 128 channels...

E I Franchow, Yana Suchy
OBJECTIVES: Accurate detection of executive dysfunction in neuropsychological assessments is complicated by the fact that executive functioning (EF) is vulnerable to temporary disruption (i.e., lapses), with more frequent lapses in older adulthood. Effortful regulation of affect (i.e., expressive suppression) is a well-known source of executive lapses in younger adults, but the generalizability of this depleting effect to older adults is unknown. The purpose of this study was to (1) determine whether EF is subject to depletion via expressive suppression and (2) to examine whether this effect is unique to EF, or whether it also applies to lower-order component processes in older adults...

Virtual reality (VR) can be used in the treatment of gambling disorder to provide emotionally charged contexts (e.g., induce cravings) where patients can practice cognitive behavior therapy (CBT) techniques in the safety of the therapist's office. This raises practical questions, such as whether the cravings are sufficient to be clinically useful but also manageable enough to remain clinically safe. Pilot data are also needed to test the development of a treatment manual and prepare large randomized control trials...
