BACKGROUND: Despite considerable effort, the neurobiological underpinnings of hyper-responsive threat processing specific to patients suffering from generalized anxiety disorder (GAD) remain poorly understood. The current functional magnetic resonance imaging (fMRI) study aims to delineate GAD-specific brain activity during immediate threat processing by comparing GAD patients to healthy controls (HC), to social anxiety disorder (SAD) and to panic disorder (PD) patients. METHOD: Brain activation and functional connectivity patterns to threat vs...

Transcranial magnetic stimulation (TMS) has recently been investigated as a possible adjuvant treatment for many neuropsychiatric disorders, and has already been approved for the treatment of drug-resistant depression in the United States and in Brazil, among other countries. Although its use in other neuropsychiatric disorders is still largely experimental, many physicians have been using it as an off-label add-on therapy for various disorders. More recently, another technique, transcranial direct current stimulation (tDCS), has also become available as a much cheaper and portable alternative to TMS, although its mechanisms of action are different from those of TMS...

Sexual abuse is very common. In the Netherlands 42% of women and 13% of men aged over 25 years have experienced unacceptable sexual behaviour. Most victims do not seek professional help nor do they report the abuse to the police, and most of the victims who do seek medical help do not mention the abuse. Doctors often do not recognize the signs of sexual abuse. Most victims of rape have symptoms that may develop into posttraumatic stress disorder (PTSD) if they persist for more than 4 weeks, such as sleep problems or panic attacks...

BACKGROUND: Our purpose was to examine the reliability and validity of the Chinese version of the Patient Health Questionnaire-15 (PHQ-15) in Taiwan, and to explore its relation to somatoform disorders (DSM-IV) and to somatic symptom and related disorders (DSM-5). METHODS: We recruited 471 individuals, 151 with somatoform disorders and 200 with somatic symptom and related disorders. Subjects completed the Chinese version of the PHQ-15, Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and received a DSM-IV- and DSM-5-based diagnostic interview...

BACKGROUND: Many previous studies have indicated that individuals who are depressed or at risk for depression are characterized by increased levels of morning cortisol and a greater cortisol awakening response (CAR). However, despite the high comorbidity between depressive and anxiety disorders, fewer studies have examined whether these diurnal cortisol abnormalities are also characteristic of anxiety or risk for anxiety. METHODS: In the present study we examined cortisol in a community sample of 476 female adolescents and related it to maternal history of depression and/or anxiety disorders...

The ability to predict psychiatric readmission would facilitate the development of interventions to reduce this risk, a major driver of psychiatric health-care costs. The symptoms or characteristics of illness course necessary to develop reliable predictors are not available in coded billing data, but may be present in narrative electronic health record (EHR) discharge summaries. We identified a cohort of individuals admitted to a psychiatric inpatient unit between 1994 and 2012 with a principal diagnosis of major depressive disorder, and extracted inpatient psychiatric discharge narrative notes...

OBJECTIVE: Noradrenaline released from sympathetic nerves is removed from the neuroeffector junction via the action of the noradrenaline transporter (NET). NET impairment is evident in several clinically important conditions including essential hypertension, major depressive disorder, panic disorder and the postural orthostatic tachycardia syndrome. Only in rare instances, however, do coding single nucleotide polymorphisms (SNPs) seem to account for a defect in NET. The aim of this study was to determine whether rs7194256 (C/T), a SNP in the 3' untranslated region (UTR) of the NET gene, is associated with diseases associated with NET dysfunction, and to elucidate the mechanism involved...

OBJECTIVES: The general practitioner (GP) is the most frequently consulted health professional by patients with common mental disorders (CMD). Yet approximately half of cases are not detected by the GP. Many factors linked to the patient, the doctor and the health care system influence detection. For example, detection rates are higher when patients are better known to their GP. On the other hand, patients visiting a different GP for reasons of dissatisfaction with previous care are more likely to be detected on the survey-day...

Previous studies found high prevalence rates of personality disorders (PDs) in patients with hypochondriasis; however, assessment was often based only on questionnaires. In the current study, a sample of 68 patients with hypochondriasis was compared to 31 patients with panic disorder and to 94 healthy controls. Participants were investigated with the Structured Clinical Interview for DSM-IV Personality Disorders questionnaire (SCID-II questionnaire) and the SCID-II interview. Based on the cut-off scores of the SCID-II questionnaire, we found a prevalence rate of 45...

The DSM-5 highlights the use of dimensional assessments of mental health as a supplement to categorical diagnoses. This study investigated the psychometric properties of the DSM-5 Dimensional Anxiety Scales in a Brazilian community sample. Dimensional scales for generalized anxiety disorder, social anxiety disorder, panic disorder, agoraphobia, and specific phobia were administered to 930 adults aged 18 to 70, 64.2% female. Psychometric properties investigated were: unidimensionality; measurement invariance; internal consistency; composite reliability; test-retest reliability; convergent and divergent validity; category thresholds and item performance analyses...

The epidemics of Ebola virus in West Africa and Zika virus in America highlight how viruses can explosively emerge into new territories. These epidemics also exposed how unprepared we are to handle infectious disease emergencies. This is also true when we consider hypothesized new clinical features of infection, such as the associations between Zika virus infection and severe neurological disease, including microcephaly and Guillain-Barré syndrome. On the surface, these pathologies appear to be new features of Zika virus infection, however, causal relationships have not yet been established...

Indigenous populations are considered at higher risk of psychiatric disorder but many studies do not include direct comparisons with similar non-Indigenous controls. We undertook a meta-analysis of studies that compared the prevalence of depression and anxiety disorders in Indigenous populations in the Americas with those of non-Indigenous groups with similar socio-demographic features (Registration number: CRD42015025854). A systematic search of PubMed, Medline, PsycInfo, PsycArticles, ScienceDirect, EMBASE, and article bibliographies was performed...

Selective stimulation of carotid chemoreceptors by intravenous infusion of low doses of potassium cyanide (KCN) produces short-lasting escape responses that have been proposed as a model of panic attack. In turn, preclinical studies suggest that facilitation of the endocannabinoid system attenuate panic-like responses. Here, we compared the effects of cannabinoid-related compounds to those of alprazolam, a clinically effective panicolytic, on the duration of the escape reaction induced by intravenous infusion of KCN (80μg) in rats...

Recently, there has been an increase in the consumption of designer drugs, substances aimed at producing psychoactive, energizing, euphoric or anesthetic effects. Designer drugs are substitutes of actual narcotics, whose possession is banned under Polish law according to the Act of 29 July 2005. The latest reports suggest that the number of synthetic psychoactive substances is increasing. In the span of 2012, a total of 28 new synthetic cannabinoids were discovered in member states of the European Union. Synthetic psychoactive substances appear in different forms on the market: tablets (often very colourful and interestingly-shaped), seeds, dried product (sprayed with synthetic substance and redried), crystals or powder...

BACKGROUND: Panic disorder is common and deleterious to mental well-being. Psychological therapies and pharmacological interventions are both used as treatments for panic disorder with and without agoraphobia. However, there are no up-to-date reviews on the comparative efficacy and acceptability of the two treatment modalities, and such a review is necessary for improved treatment planning for this disorder. OBJECTIVES: To assess the efficacy and acceptability of psychological therapies versus pharmacological interventions for panic disorder, with or without agoraphobia, in adults...

In this article we undertake a systematic analysis of why border enforcement backfired as a strategy of immigration control in the United States. We argue theoretically that border enforcement emerged as a policy response to a moral panic about the perceived threat of Latino immigration to the United States propounded by self-interested bureaucrats, politicians, and pundits who sought to mobilize political and material resources for their own benefit. The end result was a self-perpetuating cycle of rising enforcement and increased apprehensions that resulted in the militarization of the border in a way that was disconnected from the actual size of the undocumented flow...

BACKGROUND: Anxiety sensitivity (AS) refers to a fear of anxiety-related sensations and is a dispositional variable especially elevated in patients with panic disorder (PD). Although several functional imaging studies of AS in patients with PD have suggested the presence of altered neural activity in paralimbic areas such as the insula, no study has investigated white matter (WM) alterations in patients with PD in relation to AS. The objective of this study was to investigate the WM correlates of AS in patients with PD...

Acceptance and Commitment Therapy (ACT) can be effective in treating anxiety disorders, yet there has been no study on Internet-delivered ACT for social anxiety disorder (SAD) and panic disorder (PD), nor any study investigating whether therapist guidance is superior to unguided self-help when supplemented with a smartphone application. In the current trial, n=152 participants diagnosed with SAD and/or PD were randomized to therapist-guided or unguided treatment, or a waiting-list control group. Both treatment groups used an Internet-delivered ACT-based treatment program and a smartphone application...

Panic disorder is a common mental health condition, but little is known about panic disorder in non-Caucasian populations. The purpose of this study is to describe the epidemiology, clinical features, and comorbidities of panic attacks and panic disorder in two large American Indian (AI) tribes (N=3084). A culturally-adapted version of the Composite International Diagnostic Interview assessed panic attacks, panic disorder, and various psychiatric comorbidities. After adjusting for age, gender, and tribe, linear and logistic regression analyses were conducted to compare AIs with panic disorder to those with panic attacks only on clinical characteristics and panic symptoms...

Functional and psychiatric disorders that cause vestibular symptoms (i.e., vertigo, unsteadiness, and dizziness) are common. In fact, they are more common than many well-known structural vestibular disorders. Neurologists and otologists are more likely to encounter patients with vestibular symptoms due to persistent postural-perceptual dizziness or panic disorder than Ménière's disease or bilateral vestibular loss. Successful approaches to identifying functional and psychiatric causes of vestibular symptoms can be incorporated into existing practices without much difficulty...
