AIM: The aim of this study was to investigate symptoms of swallowing difficulty in Panic Disorder (PD) patients and the factors associated with these symptoms. METHODS: In the pre-phase of the study, 22 PD patients who were treated in psychiatry outpatient clinics and who were found to have swallowing difficulty were evaluated. PD patients were asked to write about their thoughts, feelings and behaviors associated with swallowing difficulty. Later, these texts were examined and 41 expressions were identified in which patients described their swallowing difficulty...

The validity of joint attention assessment in school-aged children with ASD is unclear (Lord, Jones, Journal of Child Psychology and Psychiatry 53(5):490-509, 2012). This study examined the feasibility and validity of a parent-report measure of joint attention related behaviors in verbal children and adolescents with ASD. Fifty-two children with ASD and 34 controls were assessed with the Childhood Joint Attention Rating Scale (C-JARS). The C-JARS exhibited internally consistency, α = 0.88, and one factor explained 49% of the scale variance...

Luis Ohman, Adrián P Fantini
One of the central matters in forensic psychiatry is its culpability. Day after day we, the mental health professionals, are subpoenaed in different courts of our country to assess the mental state of a given individual in order to endorse a judge so that he can issue their view pertaining the culpability and the responsibility of accused subjects. Our current National Criminal Code, dating from 1921, in Art. 34 sub 1 holds for culpability a dichotomous model in which an individual is responsible and must be accountable for his behavior or not responsible and in such case must no be held accountable in criminal courts...

Paternal environmental perturbations including exposure to drugs of abuse can produce profound effects on the physiology and behavior of offspring via epigenetic modifications. Here we show that adult drug-naive male offspring of cocaine-exposed sires have memory formation deficits and associated reductions in NMDA receptor-mediated hippocampal synaptic plasticity. Reduced levels of the endogenous NMDA receptor co-agonist d-serine were accompanied by increased expression of the d-serine degrading enzyme d-amino acid oxidase (Dao1) in the hippocampus of cocaine-sired male progeny...

Cannabis-induced acute psychotic-like states (CIAPS) represent a growing health issue, but their underlying neurobiological mechanisms are poorly understood. The use of antipsychotics and benzodiazepines against CIAPS is limited by side effects and/or by their ability to tackle only certain aspects of psychosis. Thus, safer wide-spectrum treatments are currently needed. Although the blockade of cannabinoid type-1 receptor (CB1) had been suggested as a therapeutical means against CIAPS, the use of orthosteric CB1 receptor full antagonists is strongly limited by undesired side effects and low efficacy...

Direct communication between different nervous systems has been recently reported through Brain-to-Brain-Interfaces and brainet. Closed loops systems between the brain and the spinal cord from the same individual have also been demonstrated. However, the connection between different nervous systems through the spinal cord has not yet been considered. This paper raises the hypothesis that connecting two spinal cords (spinal cord - spinal cord connection) is an indirect mean for communication of two brains and a direct way of communication between two nervous systems...

BACKGROUND: In an attempt to resolve questions regarding the symptom classification of autism spectrum disorder (ASD), previous research generally aimed to demonstrate superiority of one model over another. Rather than adjudicating which model may be optimal, we propose an alternative approach that integrates competing models using Goldberg's bass-ackwards method, providing a comprehensive understanding of the underlying symptom structure of ASD. METHODS: The study sample comprised 3,825 individuals, consecutive referrals to a university hospital developmental disabilities specialty clinic or a child psychiatry outpatient clinic...

Accumulation of non-cell autonomous Otx2 homeoprotein in postnatal mouse visual cortex (V1) has been implicated in both the onset and closure of critical period (CP) plasticity. Here, we show that a genetic point mutation in the glycosaminoglycan recognition motif of Otx2 broadly delays the maturation of pivotal parvalbumin-positive (PV+) interneurons not only in V1 but also in the primary auditory (A1) and medial prefrontal cortex (mPFC). Consequently, not only visual, but also auditory plasticity is delayed, including the experience-dependent expansion of tonotopic maps in A1 and the acquisition of acoustic preferences in mPFC, which mitigates anxious behavior...

Midbrain dopamine neurons are crucial for many behavioral and cognitive functions. As the major excitatory input, glutamatergic afferents are important for control of the activity and plasticity of dopamine neurons. However, the role of glutamatergic input as a whole onto dopamine neurons remains unclear. Here we developed a mouse line in which glutamatergic inputs onto dopamine neurons are specifically impaired, and utilized this genetic model to directly test the role of glutamatergic inputs in dopamine-related functions...

Genetic factors significantly influence susceptibility for substance abuse and mood disorders. Rodent studies have begun to elucidate a role of Cav1.3 L-type Ca(2+) channels in neuropsychiatric-related behaviors, such as addictive and depressive-like behaviors. Human studies have also linked the CACNA1D gene, which codes for the Cav1.3 protein, with bipolar disorder. However, the neurocircuitry and the molecular mechanisms underlying the role of Cav1.3 in neuropsychiatric phenotypes are not well established...

BACKGROUND: Primary care in South Korea has no effective screening system to identify high-risk suicide patients despite to the possibility of hidden patients. The present study examined the prevalence of suicidal ideation and depression among primary care patients and investigated rates of recognition and management strategies of physicians as they encountering patients with suicidal ideation and depression in primary care settings. METHODS: This study was conducted as a two-part survey of patients visiting primary care clinics and their physicians...

The molecular genetics of panic disorder (PD) with and without agoraphobia (AG) are still largely unknown and progress is hampered by small sample sizes. We therefore performed a genome-wide association study with a dimensional, PD/AG-related anxiety phenotype based on the Agoraphobia Cognition Questionnaire (ACQ) in a sample of 1370 healthy German volunteers of the CRC TRR58 MEGA study wave 1. A genome-wide significant association was found between ACQ and single non-coding nucleotide variants of the GLRB gene (rs78726293, P=3...

The Research Domain Criteria (RDoC) matrix has been developed to reorient psychiatric research towards measurable behavioral dimensions and underlying mechanisms. Here we used a new genetic rat model with a loss of function point mutation in the dopamine transporter (DAT) gene (Slc6a3_N157K) to systematically study the RDoC matrix (www.nimh.nih.gov/research-priorities/rdoc/constructs/rdoc-matrix.shtml). First, we examined the impact of the Slc6a3_N157K mutation on monoaminergic signaling. We then performed behavioral tests representing each of the five RDoC domains - negative and positive valence systems, cognitive, social, and in arousal/regulatory systems...

: 232 Background: Screening for distress in cancer patients (pts) is recommended by several national guidelines. High distress scores are associated with increased depression. We established universal depression screening and investigated its impact on cancer patient management. METHODS: Patient Health Questionnaire (PHQ9) was administered to newly diagnosed cancer patients prior to receiving their first non-oral antineoplastic agent. Patient demographics, disease characteristics, chronic medication load, antidepressant use, treatment interruptions, weight change, referral and adherence to psychiatry were recorded...

Kristen is a 13-year-old girl with Down syndrome (DS) who was seen urgently with concerns of cognitive and developmental regression including loss of language, social, and toileting skills. The evaluation in the DS clinic focused on potential medical diagnoses including atlantoaxial joint instability, vitamin deficiency, obstructive sleep apnea (OSA), and seizures. A comprehensive medical evaluation yielded only a finding of moderate OSA. A reactive depression was considered in association with several psychosocial factors including moving homes, entering puberty/onset of menses, and classroom change from an integrated setting to a self- contained classroom comprising unfamiliar peers with behavior challenges...

Systemic inflammation is accompanied by profound behavioral and mood changes that resemble symptoms of depression. Findings in animals suggest that pro-inflammatory cytokines released by activated immune cells in the periphery evoke these behavioral symptoms by driving inflammatory changes in the brain. However, experimental data in humans are lacking. Here we demonstrate in healthy male volunteers (10 endotoxin treated, 8 placebo treated) that intravenous administration of low-dose endotoxin (0.8 ng/kg body weight), a prototypical pathogen-associated molecular pattern that activates the innate immune system, not only induces a significant increase in peripheral blood cytokine concentrations (that is, tumor necrosis factor-α, interleukin (IL)-6, IL-10) but also results, with some latency, in a robust and selective increase of IL-6 in the cerebrospinal fluid (CSF)...

Manic episodes are one of the major diagnostic symptoms in a spectrum of neuropsychiatric disorders that include schizophrenia, obsessive-compulsive disorder and bipolar disorder (BD). Despite a possible association between BD and the gene encoding phospholipase Cγ1 (PLCG1), its etiological basis remains unclear. Here, we report that mice lacking phospholipase Cγ1 (PLCγ1) in the forebrain (Plcg1(f/f); CaMKII) exhibit hyperactivity, decreased anxiety-like behavior, reduced depressive-related behavior, hyperhedonia, hyperphagia, impaired learning and memory and exaggerated startle responses...

Wolfram syndrome is a relatively unexplored entity in clinical psychiatry. Historically, the discovery of a specific WFS1 gene had generated huge fanfare regarding specific genetic causations of psychiatric disorders. While the initial enthusiasm has faded now, association of Wolfram syndrome with psychiatric illnesses like schizophrenia, psychosis and suicidal behavior still remain important for understanding biological underpinnings of such disorders. We report a case of Wolfram syndrome presenting with multiple manic episodes, discuss possible genetic underpinnings for the affective symptoms and then discuss certain issues regarding management...
