Neurofeedback training builds upon the simple concept of instrumental conditioning, i.e. behaviour that is rewarded is more likely to reoccur, an effect Thorndike referred to as the 'law of effect'. In the case of neurofeedback, information about specific electroencephalographic activity is fed back to the participant who is rewarded whenever the desired electroencephalography pattern is generated. If some kind of hyperarousal needs to be addressed, the neurofeedback community considers sensorimotor rhythm neurofeedback as the gold standard...

Huntington's disease (HD) is a fatal, neurodegenerative disorder in which patients suffer from mobility, psychological and cognitive impairments. Existing therapeutics are only symptomatic and do not significantly alter the disease progression or increase life expectancy. HD is caused by expansion of the CAG trinucleotide repeat region in exon 1 of the Huntingtin gene (HTT), leading to the formation of mutant HTT transcripts (muHTT). The toxic gain-of-function of muHTT protein is a major cause of the disease...

OBJECTIVE: Whereas there is growing evidence that repetitive transcranial magnetic stimulation (rTMS) favorably impacts on symptoms of obsessive-compulsive disorders (OCD), less is known regarding the influence of rTMS on cognitive performance of patients with OCD. Here, we tested the hypothesis that rTMS has a positive impact both on symptom severity and executive functions in such patients. METHODS: We assessed 10 patients diagnosed with OCD (mean age: 33.5 years) and treated with a standard medication; they were randomly assigned either to a treatment-first or to a sham-first condition...

The ability of the parasympathetic nervous system to flexibly adapt to changes in environmental context is thought to serve as a physiological indicator of self-regulatory capacity, and deficits in parasympathetic flexibility appear to characterize affective disorders such as depression. However, whether parasympathetic flexibility (vagal withdrawal to emotional or environmental challenges such as sadness, and vagal augmentation during recovery from sadness) could facilitate the effectiveness of adaptive affect regulation strategies is not known...

Purpose: Stuttering is a speech disorder frequently accompanied by anxiety in social-evaluative situations. A growing body of research has confirmed a significant rate of social anxiety disorder among adults who stutter. Social anxiety disorder is a chronic and disabling anxiety disorder associated with substantial life impairment. Several influential models have described cognitive-behavioral factors that contribute to the maintenance of social anxiety in nonstuttering populations. The purpose of the present article is to apply these leading models to the experience of social anxiety for people who stutter...

Objective: Individuals with spinal cord injury (SCI), traumatic brain injury (TBI), and stroke experience a variety of neurologically related deficits across multiple domains of function. The NIH Toolbox for the Assessment of Neurological and Behavioral Function (NIHTB) examines motor, sensation, cognition, and emotional functioning. The purpose of this paper is to establish the validity of the NIHTB in individuals with neurologic conditions. Methods: Community-dwelling individuals with SCI (n = 209), TBI (n = 184), or stroke (n = 211) completed the NIHTB...

Objective: Non-concussed individuals may report a variety of concussion-like symptoms even in the absence of a diagnosed brain injury. Previous studies described concussion-like symptom reporting in adolescent athletes. This study provides complementary data on concussion-like symptoms in collegiate athletes. Methods: We analyzed baseline symptom scales from 738 collegiate athletes (452 men and 286 women) who completed either the Sport Concussion Assessment Tool, 3 Symptom Evaluation (S3SE; n = 377) or the Post-Concussion Scale (PCS; n = 361) and determined if subjects met criteria for diagnosis of International Classification of Diseases 10th Revision (ICD-10) postconcussional syndrome...

This study included 168 and 85 mother-infant dyads from Asian and United States of America cohorts to examine whether a genomic profile risk score for major depressive disorder (GPRSMDD) moderates the association between antenatal maternal depressive symptoms (or socio-economic status, SES) and fetal neurodevelopment, and to identify candidate biological processes underlying such association. Both cohorts showed a significant interaction between antenatal maternal depressive symptoms and infant GPRSMDD on the right amygdala volume...

Objective: The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) has been shown to be an effective screener for detecting neurocognitive impairments in English speaking forensic psychiatric inpatients, but no studies have examined whether the RBANS would have the same utility among monolingual Spanish speaking inpatients. This study sought to examine RBANS performance, as well as risk factors (i.e., educational, neurological, and medical) influencing RBANS performance, in that particular population...

BACKGROUND: Fragile X Syndrome (FXS) is the main genetic cause of autism and intellectual deficiency resulting the absence of the Fragile X Mental Retardation Protein (FMRP). Clinical picture is characterized by cognitive impairment associated with a broad spectrum of psychiatric comorbidities including autism spectrum disorders and attention-deficit/hyperactivity disorders. Some of these disorders have been associated with lipid abnormalities and lower cholesterol levels. Since lipids are important for neuronal development, we aim to investigate the lipid profile of French Canadian-FXS individuals and to identify the altered components of cholesterol metabolism as well as their association with clinical profile...

INTRODUCTION: Minor neurocognitive disorder (MiND; previously mild cognitive impairment) is a transitional zone between normal cognitive function and early stages of major neurocognitive disorder (previously called dementia). Of people with MiND, 5% to 10% progress to major neurocognitive disorder. Simple interventions such as memory activities, balance exercises, and anti-inflammatory diets have been shown to improve cognitive ability. Also, education and support in group settings have proved beneficial for patients with MiND...

Autism spectrum disorder currently lacks an explanation that bridges cognitive, computational, and neural domains. In the past 5 years, progress has been sought in this area by drawing on Bayesian probability theory to describe both social and nonsocial aspects of autism in terms of systematic differences in the processing of sensory information in the brain. The present article begins by synthesizing the existing literature in this regard, including an introduction to the topic for unfamiliar readers. The key proposal is that autism is characterized by a greater weighting of sensory information in updating probabilistic representations of the environment...

OBJECTIVES: This study sought to assess the utility of Imagery Rehearsal Therapy (IRT) for nightmares in an inpatient psychiatric setting. Although IRT enjoys a substantial evidence base for efficacy in various populations, data with psychiatric inpatients are lacking. PARTICIPANTS: Participants were 20 adult psychiatric inpatients (11 male, 9 female; mean age=43.4), in an extended stay psychiatric inpatient facility. All participants were diagnosed with multiple, treatment resistant, comorbid conditions, including mood disorders, anxiety disorders, personality disorders, and substance-related disorders...

BCAP31, encoded by BCAP31, is involved in the export of transmembrane proteins from the endoplasmic reticulum. Pathogenic variants in BCAP31 results in global developmental delay, dystonia, deafness and dysmorphic features in males, called deafness, dystonia, and cerebral hypomyelination (DDCH) syndrome. We report a new patient with BCAP3-associated encephalopathy, DDCH syndrome, sensorineural hearing loss, generalized dystonia, and choreoathetosis. This 3.5-year-old boy had microcephaly and failure to thrive within the first 3 months of life...

Executive function (EF) is a multifaceted construct that has been defined as a set of higher-order cognitive processes that allow for flexibility, self-regulation, strategic planning, and goal-directed behaviors. EFs have been studied in numerous clinical disorders using a variety of neuropsychological tasks and, more recently, neuroimaging techniques. The underlying physiological substrates of EF were historically attributed to the frontal lobes; however, recent studies suggest more widespread involvement of additional brain regions...

BACKGROUND: Bipolar disorder (BD) patients exhibit cognitive impairments during euthymic states. Studies suggest that manic episodes may be correlated to cognitive impairments. The present study investigated the relationship between predominant polarity and the cognitive deficits frequently detected in bipolar patients. We hypothesize that mania predominant polarity (MPP) patients should exhibit greater cognitive impairments in comparison to depressive (DPP) and indefinite predominant polarity (IPP) patients and healthy control (HC) individuals...

BACKGROUND: Individuals with bipolar disorder present with moderate impairments in social cognition during the euthymic state. The impairment extends to theory of mind and to the perception of emotion in faces and voices, but it is unclear if emotion perception from body movements is affected. The main aim of this study was to examine if participants with bipolar disorder perform worse than healthy control participants on a task using point-light displays of human full figures moving in a manner indicative of a basic emotion (angry, happy, sad, fearful, neutral/no emotion)...

PURPOSE: Cushing's syndrome (CS) is an endocrine disorder due to prolonged exposure to cortisol. Recently, microstructural white matter (WM) alterations detected by diffusion tensor imaging (DTI) have been reported in CS patients, and related to depression, but other functional significances. remain otherwise unclear. We aimed at investigating in more depth mood symptoms in CS patients, and how these relate to cognition (information processing speed), and to WM alterations on DTI. METHODS: The sample comprised 35 CS patients and 35 healthy controls...
