AIMS: We investigated preclinical abnormalities revealed by transcranial sonography (TCS) in patients with idiopathic REM sleep behavior disorder (iRBD) compared with those revealed in patients with multiple system atrophy (MSA) or Parkinson's disease (PD) and in normal controls. METHODS: Twenty-two patients with iRBD, 21 patients with MSA, 22 patients with PD and 21 normal controls were included in this study. All participants underwent one night of video-polysomnography (PSG) monitoring, and the sleep parameters were analyzed using Polysmith software and by visual analysis...

AIMS: The aims of this study were to determine whether the serum levels of precursor brain-derived neurotrophic factor (proBDNF), mature BDNF (mBDNF), and matrix metalloproteinase-9 (MMP-9) are altered in patients with eating disorders (EDs) including anorexia nervosa (AN) and bulimia nervosa (BN), and to explore whether those levels are associated with decision-making abilities. METHODS: Nineteen women with AN, 28 women with BN, and 22 age-matched healthy women (HC) were enrolled in the current study...

LETTER

This is the first case of Sneddon syndrome-related psychotic symptoms leading to a suicide attempt, although a previous study by Laurence et al. reported a case of a suicide attempt in the context of bipolar symptoms related to Sneddon syndrome.

AIM: Structural and functional magnetic resonance imaging (MRI) studies have revealed evidence of brain abnormalities in post-traumatic stress disorder (PTSD) patients. Cortical complexity and local gyrification index (lGI) reflects potential biological processes associated with normal or abnormal cognitive functioning. In the current study, lGI is used to explore cortical folding in PTSD patients involved in motor vehicle accidents (MVCs). METHODS: MRI brain scans were acquired from 18PTSD patients who suffered MVCs at least 6 months previously and 18 healthy control subjects...

AIM: The aim of this study is to clarify whether improvement of cognitive functioning by cognitive remediation therapy can improve work outcome in schizophrenia and other severe mental illness when combined with supported employment. METHODS: The Subjects of this study were persons with severe mental illness diagnosed with schizophrenia, major depression, or bipolar disorder (ICD-10) and cognitive dysfunction who participated in both cognitive remediation using the Thinking Skills for Work program and supported employment program in a multisite, randomized controlled study...

LETTER
Kunihiro Iwamoto, Hiroshige Fujishiro, Norio Ozaki
Although late-life depression is major concern, half of patients fail to respond to first-line pharmacotherapy. Secondary strategies are required and recent study showed that aripiprazole augmentation is useful treatment. This report shows that aripiprazole augmentation can obscure Lewy body disease in late-life depression. Aripiprazole augmentation initially ameliorates depressive symptoms of Lewy body disease without triggering extrapyramidal dysfunction and eventually becomes less effective and evokes extrapyramidal dysfunction as the disease progresses...

AIM: Treatment-resistant depression patients are more likely to suffer from comorbid physical and mental disorders, experience marked and protracted functional impairment, and incur higher healthcare costs than non-affected individuals. Magnesium sulfate is a treatment option that may offer great potential for patients with treatment-resistant depression based on prior work in animals and humans. METHODS: Twelve subjects with mild or moderate treatment-resistant depression were randomized into a double-blind crossover trial to receive an infusion of 4 gram of magnesium sulfate in 5% dextrose or placebo infusion of 5% dextrose with a 5-day washout in between the 8-day intervention period...

AIM: Studies have reported that cognitive decline occurs after the onset of schizophrenia despite heterogeneity in cognitive function among patients. The aim of this study was to investigate the degree of estimated cognitive decline in patients with schizophrenia by comparing estimated premorbid intellectual functioning and current intellectual functioning. METHODS: A total of 446 patients with schizophrenia (228 male, 218 female), consisting of three sample sets obtained from 11 psychiatric facilities, and 686 healthy controls participated in this study...

REVIEW
Ekaterina Sigitova, Zdeněk Fišar, Jana Hroudová, Tereza Cikánková, Jiří Raboch
The most common mood disorders are major depressive disorders and bipolar disorders. The pathophysiology of bipolar disorder is complex, multifactorial, and not fully understood. Creation of new hypotheses in the field gives impetus for studies and searching new biomarkers of the bipolar disorder. Conversely, new biomarkers facilitate not only diagnosis of a disorder and monitoring of biological effects of treatment, but also formulation of new hypotheses of the causes and pathophysiology of the bipolar disorder...

Several studies have recently demonstrated that the volumes of specific brain regions are reduced in children and adolescents with post-traumatic stress disorder (PTSD) compared with those of healthy controls. Our study investigated the potential association between early traumatic experiences and altered brain regions and functions. We conducted a systematic review of the scientific literature regarding functional MRI and a meta-analysis of structural MRI studies that investigated cerebral region volumes in pediatric patients with PTSD...

AIM: Complex sleep behaviors (CSBs) are often associated with the use of hypnotic drugs. This study investigated the prevalence and correlates of CSBs among psychiatric patients who were given flunitrazepam. METHODS: From June 2011 to May 2012, a total of 268 psychiatric outpatients who had received flunitrazepam for at least 3 months were enrolled. Data on occurrence of CSBs, demographic characteristics, flunitrazepam dosage and duration of use, psychiatric diagnoses, physical illnesses, and alcohol use were collected...

AIMS: Many studies have reported that the prevalence of mental illness and cognitive disability is higher among homeless individuals compared to the general population, and the rates of mental illness among the homeless population have recently increased. This study compared causes of homelessness or barriers to escaping homelessness for people with/without mental illness/cognitive disability, revealed problems with the Japanese homeless policy, and proposed an effective and necessary support system...

AIM: The study aimed to develop two Japanese versions of King's Stigma Scale, a full version (version.1) and a short version (version.2), through psychometric property testing. METHODS: The sample included 112 people with mental illness. We tested the constructs of the scales using both confirmatory and exploratory factor analyses. Internal consistency and test-retest reliability were tested. We examined convergent validity with self-esteem or perceived stigma, and different group validity, using the Kessler Psychological Distress Scale (K6)...
