Major depressive disorder (MDD) is a growing problem worldwide. Though, the etiology remains unresolved, circadian rhythm disturbances are frequently observed in MDD and thus is speculated to play a key role herein. The present study focuses on circadian rhythm disturbances in the chronic mild stress (CMS) animal model of depression and examined whether the atypical antidepressant, agomelatine, which is mediating its action via melatonergic and serotonergic receptors, is capable of resynchronizing the perturbed rhythm...

The dancing mania erupted in the 14th century in the wake of the Black Death, and recurred for centuries in central Europe - particularly Germany, the Netherlands, and Belgium - finally abating in the early 17th century. The term "dancing mania" was derived from "choreomania," a concatenation of choros (dance) and mania (madness). A variant, tarantism, was prevalent in southern Italy from the 15th to the 17th centuries, and was attributed at the time to bites from the tarantula spider. Affected individuals participated in continuous, prolonged, erratic, often frenzied and sometimes erotic, dancing...

Douglas J Lanska
In the late 19th century, jumping (French Canadians in Maine, USA), miryachit (Siberia), and latah (Southeast Asia) were among a group of similar disorders described around the world, each of which manifests as an exaggerated startle response with additional late-response features that were felt by some to overlap with hysteria or tics. The later features following the exaggerated startle reaction variably include mimesis (e.g., echopraxia, echolalia) and automatic obedience. These reaction patterns tended to persist indefinitely in affected individuals...

Violence is a significant public health problem representing one of the leading causes of death worldwide for people aged 15-44 years. Although violence and aggression are more frequent in adolescence and early adult life and decline with advancing age, these conditions can still develop for the first time in old age especially in association with organic brain disorder. Rates of violent death vary according to country income levels and are twice as higher in low- to middle-income countries than in high-income countries...

This chapter is aimed at highlighting the recent findings concerning physiopathology, diagnosis, and management of conversion, factitious disorder, and malingering. Conversion disorder is the unintentional production of neurological symptom, whereas malingering and factitious disorder represent the voluntary production of symptoms with internal or external incentives. They have a close history and this has been frequently confounded. Practitioners are often confronted to medically unexplained symptoms; they represent almost 30% of neurologist's consultation...

Non-bizarre delusion, defined as a false belief possible although highly unlikely, is the main manifestation of delusional disorders, previously known as paranoia. Based on the predominant delusional themes, 5 main subtypes may be described - erotomanic, grandiose, jealous, persecutory, and somatic. We present here 2 main delusional disorders, the De Clérambault syndrome and the Othello syndrome, and another closely related to the previous ones - Folie à deux. In the De Clérambault syndrome, the main delusional theme is erotomanic type, related to passional delirium where the patient has strong sexual feelings towards another person and has the belief that this other person is deeply in love with him or her...

High prevalence of behavioral and psychiatric disorders in adults with Prader-Willi Syndrome (PWS) has been reported in last few years. However, data are confusing and often contradictory. In this article, we propose a model to achieve a better understanding of the psychopathological features in adults with PWS. The study is based on clinical observations of 150 adult inpatients, males and females. Non-parametric statistics were performed to analyse the association of psychopathological profiles with genotype, gender and age...

Childhood obesity is multi factorial health condition, so the simple evaluation of body fat will not be sufficed to manage the global epidemic of childhood obesity. Literature consistently provides evidence for physical health risks associated with childhood obesity; however in recent times, mental health of the obese children has also gained attention of the researchers as well as clinicians. Obese children experience number of psycho-social problems that significantly affect their quality of life and wellbeing...

Ilex paraguariensis, yerba mate is a native plant from the southern region of Brazil. Studies showed that yerba mate has an antioxidant potential, which could help to reduce the risk of developing neurodegenerative diseases, as Alzheimer's Disease (AD). It's known that I. paraguariensis grows in acid soils with aluminium (Al), which is bioavailable in these soils. Al has a neurotoxic potential related with the progression of neurological disorders. This study aim was to evaluate the potential of I. paraguariensis in the etiology of AD using strains of Caenorhabditis elegans and the concentration of Al and antioxidants in the yerba mate extract...

Traumatizing events are known to have consequences for the victim which may lead to the development of several well-known mental disorders. Recent research has shown that traumatic events may affect not only the victims' lives, but also that of their progeny. It is generally accepted that this transmission of trauma occurs through parental behavior; however as has been recently discovered, the effects of trauma may also be inherited due to induced alterations in gene expression. These changes, so called epigenetic modifications, illuminate the interaction between genes and the environment...

Bulimia nervosa (BN) is a psychiatric illness defined by preoccupation with body image (cognitive 'symptoms'), binge eating and compensatory behaviors. Although diagnosed BN has been related to grey matter alterations, characterization of brain structure in women with a range of BN symptoms has not been made. This study examined whether cortical thickness (CT) values scaled with severity of BN cognitions in 33 women with variable BN pathology. We then assessed global structural connectivity (SC) of CT to determine if individual differences in global SC relate to BN symptom severity...

Effective evaluation of costs and benefits is a core survival capacity that in humans is considered as optimal, "rational" decision-making. This capacity is vulnerable in neuropsychiatric disorders and in the aftermath of chronic stress, in which aberrant choices and high-risk behaviors occur. We report that chronic stress exposure in rodents produces abnormal evaluation of costs and benefits resembling non-optimal decision-making in which choices of high-cost/high-reward options are sharply increased...

Increasing awareness of, and information about, overdose risk is an appropriate approach in risk reduction. e-Health technology in substance use disorders is an opportunity to support behavioral changes related to public health concerns. The present study aimed to evaluate the short-term impact of an innovative e-health psychoeducational software, the Overdose RIsk InfOrmatioN (ORION) tool. The ORION programme provided relevant information to opioid-dependent individuals about the risk of suffering a drug overdose as a result of high risky and dysfunctional behaviors...

The ability to control the electrical conductivity of solid-state oxides using structural parameters has been demonstrated. A correlation has been established between the electrical conductivity and structural order in a series of oxygen-deficient perovskites using X-ray and neutron diffraction, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and electrical conductivity studies at a wide temperature range, 25-800 °C. The crystal structure of CaSrFeCoO6-δ has been determined, and its stark contrast to Ca2FeCoO6-δ and Sr2FeCoO6-δ has been demonstrated...

Engagement in activities is crucial to improve quality of life in dementia. Yet, its measurement relies exclusively on behavior observation and the influence that behavioral and psychological symptoms of dementia (BPSD) have on it is overlooked. This study investigated whether quantity of movement, gauged with a wrist-worn accelerometer, could be a sound measure of engagement and whether apathy and depression negatively affected engagement. Fourteen participants with dementia took part in 6 sessions of activities: 3 of cognitive games (eg, jigsaw puzzles) and 3 of robot play (Pleo)...

OBJECTIVES: Altered social behavior during mood episodes in bipolar disorder often has detrimental and long-lasting interpersonal consequences. Abnormal face processing may play a role in linking brain functions to clinical symptoms and behavior. This study aimed to understand configural face processing in bipolar disorder as a function of basic communicative attributes of the face and mood symptoms using event-related brain potentials (ERPs). METHODS: Forty-two participants with bipolar I disorder (BP) and 43 healthy controls (HC) viewed face stimuli varying in emotion (neutral or fearful), head orientation (forward or deviated), and gaze direction (direct or averted) while ERPs were recorded...

The amygdala is a key brain area regulating responses to stress and emotional stimuli, so improving our understanding of how it is regulated could offer novel strategies for treating disturbances in emotion regulation. As we review here, a growing body of evidence indicates that the gut microbiota may contribute to a range of amygdala-dependent brain functions from pain sensitivity to social behavior, emotion regulation, and therefore, psychiatric health. In addition, it appears that the microbiota is necessary for normal development of the amygdala at both the structural and functional levels...

PURPOSE OF REVIEW: The purpose of this study was to review the frequency, risk factors, phenomenology, and course of prolonged recovery from concussion and of psychiatric sequelae in pediatric populations. RECENT FINDINGS: Youth with prolonged recovery from concussions have higher initial symptoms, a history of multiple and/or recent concussions, and a tendency to somatization. Depression, post-traumatic stress disorder, behavioral disorders, and perhaps, suicidal behavior disorder are more common as both short- and longer-term sequelae of concussions...

Introduction: Autism spectrum disorder (ASD) affects 1 in 68 children, is characterized by impaired social interaction and communication as well as restricted or repetitive behaviors, and varies widely with respect to its causes and presentations. There are no validated pharmacologic treatments for the core symptoms of ASD. The social, medical, and economic burdens of ASD on families and caregivers are profound. We recently showed in a small clinical trial that sulforaphane (SF) from broccoli sprouts could significantly reduce the behavioral symptoms of ASD...
