Anxiety and trauma-related disorders are psychiatric diseases with a lifetime prevalence of up to 25%. Phobias and post-traumatic stress disorder (PTSD) are characterized by abnormal and persistent memories of fear-related contexts and cues. The effects of psychological treatments such as exposure therapy are often only temporary and medications can be ineffective and have adverse side effects. Growing evidence from human and animal studies indicates that cannabidiol, the main non-psychotomimetic phytocannabinoid present in Cannabis sativa, alleviates anxiety in paradigms assessing innate fear...

Nerve growth factor (NGF) plays crucial roles in promoting neural growth and survival, and mediating synaptic and morphological plasticity. Several studies investigated the correlation between peripheral NGF levels and major psychiatric disorders, including schizophrenia (SCZ), major depressive disorder (MDD) and bipolar disorder (BPD); however, the findings were inconsistent. This meta-analysis sought to investigate blood NGF levels in patients with psychiatric disorders compared with healthy subjects and examined potential effects of blood fraction, medication and disease status...

Obsessive-compulsive disorder (OCD) is a frequent and severe disease, potentially inducing a major impairment for the patient and burden for their family. Recent research in psychiatry and neuroscience have led to better comprehension of the disease's mechanisms and helped to improve its treatment. However, a large proportion of patients have refractory symptoms, including for traditional cognitive and behavioral therapy by exposure and response prevention (ERP), leading clinicians to look for new treatments...

Psychosomatic research has advanced over the past decades in dealing with complex biopsychosocial phenomena and may provide new effective modalities of patient care. Among psychosocial variables affecting individual vulnerability, course, and outcome of any medical disease, the role of chronic stress (allostatic load/overload) has emerged as a crucial factor. Assessment strategies include the Diagnostic Criteria for Psychosomatic Research. They are presented here in an updated version based on insights derived from studies carried out so far and encompass allostatic overload, type A behavior, alexithymia, the spectrum of maladaptive illness behavior, demoralization, irritable mood, and somatic symptoms secondary to a psychiatric disorder...

OBJECTIVES: To investigate expressed emotion (EE) in couples facing breast cancer in the immediate post-surgery period. EE may be predictive of psychological disturbances that hinder both partners' capacities to cope with the stress of the disease. Severity of the disease, attachment tendencies, and couple satisfaction were tested as predictors of EE. DESIGN: The design was cross-sectional. Couples (N = 61) were interviewed 2 weeks after the women's breast surgery...

Sneddon syndrome (SS) is a rare condition and the diagnosis is made only when other more common disease entities have been excluded. Common manifestations in SS patients include hypertension, coronary artery disease, venous thrombosis, miscarriages, psychiatric disturbances, and arterial and venous thrombotic events. Most patients present in their early 30s with classic neurovascular and dermatologic signs. Currently, the main criteria for the diagnosis of SS include livedo racemosa, focal neurological deficits or evidence of stroke on magnetic resonance imaging, or characteristic vascular alterations seen on biopsy...

Chronotype, or diurnal preference, refers to behavioral manifestations of the endogenous circadian system that governs preferred timing of sleep and wake. As variations in circadian timing and system perturbations are linked to disease development, the fundamental biology of chronotype has received attention for its role in the regulation and dysregulation of sleep and related medical and psychiatric illnesses. Twin and family studies have shown that chronotype is a heritable trait, thus directing attention toward its genetic basis...

INTRODUCTION: Tardive syndrome is a troublesome complication secondary to the long-term usage of antipsychotic medication. At present, there is a lack of effective treatment for tardive syndrome. Aripiprazole has been used in the treatment of tardive syndrome, with some reports of a good response. However, other reports have suggested that tardive syndrome can actually be induced by aripiprazole. The aim of current study was to investigate whether aripiprazole is beneficial or harmful for the treatment of tardive syndrome in specific patients...

Glial cell line-derived neurotrophic factor (GDNF) plays an increasingly vital role in the pathogenesis of neuropsychiatric illnesses. Antipsychotic medications were shown to stimulate GDNF secretion from C6 glioma cells. The aims of this study were to investigate the serum concentration of GDNF, to monitor the therapeutic effect of atypical antipsychotics related to GDNF levels in drug-free schizophrenia patients, and to examine these levels in relation to psychotic symptoms. We recruited 138 drug-free schizophrenic patients and compared them with 77 matched healthy subjects...

Autoimmune encephalitis is a rare and newly described group of diseases involving autoantibodies directed against synaptic and neuronal cell surface antigens. It comprises a wide range of neuropsychiatric symptoms. Sensitive and specific diagnostic tests such as cell-based assay are primordial for the detection of neuronal cell surface antibodies in patients' cerebrospinal fluid or serum and determine the treatment and follow-up of the patients. As neurological symptoms are fairly well described in the literature, this review focuses on the nature of psychiatric symptoms occurring at the onset or during the course of the diseases...

Incidental learning of appropriate stimulus-response associations is crucial for optimal functioning within our complex environment. Positive and negative prediction errors (PEs) serve as neural teaching signals within distinct ('direct'/'indirect') dopaminergic pathways to update associations and optimize subsequent behavior. Using a computational reinforcement learning model, we assessed learning from positive and negative PEs on a probabilistic task (Weather Prediction Task - WPT) in three populations that allow different inferences on the role of dopamine (DA) signals: (1) Healthy volunteers that repeatedly underwent [(11)C]raclopride Positron Emission Tomography (PET), allowing for assessment of striatal DA release during learning, (2) Parkinson's disease (PD) patients tested both on and off L-DOPA medication, (3) early Huntington's disease (HD) patients, a disease that is associated with hyper-activation of the 'direct' pathway...

: Background/Study Context: Depression is a common psychiatric disorder in the elderly that leads to a decrease in quality of life and functional impairment, among other health problems. The study of depressive symptoms in institutionalized elderly is scarce in Latin America and can contribute to plan prevention and treatment actions in order to improve health conditions for the residents as well as quality of life. Therefore, the aim of this study is to determine the prevalence of depressive symptoms and identify its associated factors in institutionalized elderly...

BACKGROUND: Risks prediction models of 30-day all-cause hospital readmissions are multi-factorial. Severity of illness (SOI) and risk of mortality (ROM) categorized by All Patient Refined Diagnosis Related Groups (APR-DRG) seem to predict hospital readmission but lack large sample validation. Effects of risk reduction interventions including providing post-discharge outpatient visits remain uncertain. We aim to determine the accuracy of using SOI and ROM to predict readmission and further investigate the role of outpatient visits in association with hospital readmission...

OBJECTIVE: It has been widely acknowledged that the community and health professionals hold negative attitudes toward patients with impaired mental health. This constitutes a majör obstacle for those patients in coping with their disease, managing their care, and hence regulating their lives. Although studies carried out in Turkey document the presence of stigma, they provide limited information about the ways for solving this problem. Drawing on the litrature, the present study investigated the effect of medical education on stigmatization...

Anxiety is a common yet frequently overlooked psychiatric symptom in patients with ESRD treated with hemodialysis (HD). Anxiety is characterized by disruptive feelings of uncertainty, dread, and fearfulness. A variety of common medical complaints may be manifestations of an anxiety disorder, including palpitations, tremors, indigestion, numbness/tingling, nervousness, shortness of breath, diaphoresis, and fear. It is essential for the clinician to rule out specific medical conditions, including cardiovascular, pulmonary, and neurologic diseases, before ascribing these symptoms to an anxiety disorder...
