Huntington Disease (HD) is an autosomal dominant disorder characterized by motor, cognitive and behavioral features caused by a CAG expansion in the HTT gene beyond 35 repeats. The juvenile form (JHD) may begin before the age of 20years and is associated with expanded alleles as long as 60 or more CAG repeats. In this study, induced pluripotent stem cells were generated from skin fibroblasts of a 8-year-old child carrying a large size mutation of 84 CAG repeats in the HTT gene. HD appeared at age 3 with mixed psychiatric (i...

Recent cognitive models suggest that the ability to control emotional information in working memory (WM) may be implicated in the etiology and maintenance of depression. However, few studies have examined the effects of processing relevant and irrelevant emotional stimuli on WM performance in depressed adolescents. In the current study, depressed adolescents (n = 27) and healthy adolescents (n = 49) completed two versions of an emotional n-back task: a low WM load (0-back) task and a high WM load (2-back) task...

The primary cilium in neural stem cells plays distinct roles in different stages during cortical development. Ciliary dysfunctions in human (i.e., ciliopathy) cause developmental defects in multiple organs, including brain developmental delays, which lead to intellectual disabilities and cognitive deficits. However, effective treatment to this devastating developmental disorder is still lacking. Here, we first investigated the effects of ciliopathy on neural stem cells by knocking down Kif3a, a kinesin II motor required for ciliogenesis, in the neurogenic stage of cortical development by in utero electroporation of mouse embryos...

There is increasing recognition that adults with autism spectrum disorder (ASD) would benefit from treatment to improve social functioning, a key factor in adults' overall quality of life. However, the various behavioral components of social functioning (i.e., categories of behaviors underlying social functioning), including social motivation, social anxiety, social cognition, and social skills, have not all been assessed together in any sample of adults with ASD, making it difficult to know the relative levels of impairment in these various categories, the relationships among these categories, or promising targets for treatments...

Explanatory models for eating disorders have changed over time to account for changing clinical presentations. The transdiagnostic model evolved from the maintenance model, which provided the framework for cognitive behavioural therapy for bulimia nervosa. However, for many individuals (especially those at the extreme ends of the weight spectrum), this account does not fully fit. New evidence generated from research framed within the food addiction hypothesis is synthesized here into a model that can explain recurrent binge eating behaviour...

BACKGROUND: Multiple nterventions have been developed to address speech sound disorder (SSD) in children. Many of these have been evaluated but the evidence for these has not been considered within a model which categorizes types of intervention. The opportunity to carry out a systematic of interventions for SSD arose as part of a larger scale study of interventions for primary speech and language impairment in preschool children. AIMS: To review systematically the evidence for interventions for SSD in preschool children and to categorize them within a classification of interventions for SSD...

The hippocampal formation is a complex brain structure that is important in cognitive processes such as memory, mood, reward processing and other executive functions. Histological and neuroimaging studies have implicated the hippocampal region in neuropsychiatric disorders as well as in neurodegenerative diseases. This highly plastic limbic region is made up of several subregions that are believed to have different functional roles. Therefore, there is a growing interest in imaging the subregions of the hippocampal formation rather than modelling the hippocampus as a homogenous structure, driving the development of new automated analysis tools...

OBJECTIVE: Childhood loss of control (LOC) eating and attention-deficit/hyperactivity disorder (ADHD) are highly comorbid conditions and present with disordered eating behaviors, such as overeating. This study sought to delineate shared and specific abnormalities in physiological, cognitive-motivational, and behavioral components of food-specific impulsivity in children with LOC eating and ADHD. Specifically, children's reactivity and habituation to food and eating in the absence of hunger were examined...

BACKGROUND/OBJECTIVES: Behavioral problems in individuals with Alzheimer's disease (AD) impose major management challenges. Current prevention strategies are anchored to cognitive outcomes, but behavioral outcomes may provide another, clinically relevant opportunity for preemptive therapy. We sought to determine whether personality changes that predispose to behavioral disorders arise during the transition from preclinical AD to mild cognitive impairment (MCI). DESIGN: Longitudinal observational cohort study...

Mental health institutions increasingly utilise routine outcome monitoring (rom) in order to assess treatment effectiveness. It remains unclear which instruments are more sensitive to change with regard to rom in patients with an anxiety disorder: diagnosis-specific or generic instruments.<br/> AIM: To compare the sensitivity of diagnosis-specific versus generic rom-instruments in patients with an anxiety disorder.<br/> METHOD: 160 adults with an anxiety disorder received cognitive behavioural therapy at the Altrecht Academic Anxiety Centre...

Importance: Genetic factors have a well-known influence on Parkinson disease (PD) susceptibility. The largest genome-wide association study (GWAS) identified 26 independent single-nucleotide polymorphisms (SNPs) associated with PD risk. Among patients, the course and severity of symptom progression is variable, and little is known about the potential association of genetic factors with phenotypic variance. Objective: To assess whether GWAS-identified PD risk SNPs also have a cumulative association with the progression of cognitive and motor symptoms in patients with PD...

BACKGROUND/AIMS: Cenesthopathy is mainly associated with schizophrenia; however, its neurobiological basis is nowadays unclear. The general objective was to explore clinical correlates of cenesthopathy and subjective cognitive complaints in schizophrenia. METHODS: Participants (n = 30) meeting DSM-IV criteria for psychotic disorder were recruited from a psychiatry unit and assessed with: Association for Methodology and Documentation in Psychiatry (AMDP) system, Positive and Negative Syndrome Scale, Frankfurt Complaint Questionnaire (FCQ), and the Bonn Scale for the Assessment of Basic Symptoms (BSABS)...

The rapid developments in science have led to an increase in human life expectancy and thus, ageing and age-related disorders/diseases have become one of the greatest concerns in the 21st century. Cognitive abilities tend to decline as we get older. This age-related cognitive decline is mainly attributed to aberrant changes in synaptic plasticity and neuronal connections. Recent studies show that alterations in Ca2+ homeostasis underlie the increased vulnerability of neurons to age-related processes like cognitive decline and synaptic dysfunctions...

Lindsey M Collins, Meredith E Coles
BACKGROUND: Cognitive theorists posit that inflated responsibility beliefs contribute to the development of obsessive compulsive disorder (OCD). Salkovskis et al. (1999) proposed that experiencing heightened responsibility, overprotective parents and rigid rules, and thinking one influenced or caused a negative life event act as 'pathways' to the development of inflated responsibility beliefs, thereby increasing risk for OCD. Studies in adults with OCD and non-clinical adolescents support the link between these experiences and responsibility beliefs (Coles et al...

BACKGROUND: Patients with 22q11.2 deletion syndrome (22q11DS) present a high risk of developing psychosis. While clinical and cognitive predictors for the conversion towards a full-blown psychotic disorder are well defined and largely used in practice, neural biomarkers do not yet exist. However, a number of investigations indicated an association between abnormalities in cortical morphology and higher symptoms severities in patients with 22q11DS. Nevertheless, few studies included homogeneous groups of patients differing in their psychotic symptoms profile...

BACKGROUND AND PURPOSE: It has been suggested that the non-euphorogenic phytocannabinoid cannabidiol (CBD) can ameliorate adverse effects of delta-9-tetrahydrocannabinol (THC). We determined whether CBD ameliorates cognitive deficits and withdrawal signs induced by cannabinoid CB1/CB2 receptor agonists or produces these pharmacological effects on its own. EXPERIMENTAL APPROACH: The effects of THC or the CB1/CB2 receptor full agonist WIN55212 (WIN) alone, CBD alone, or their combination were tested across a range of doses...

BACKGROUND: In the Tokyo Bay Urayasu Ichikawa Medical Centre, a sleep clinic for adults and children was established in August 2012. As few sleep clinics are available in Japan that are specifically for children, this clinic provides the opportunity to provide data on child patients who have been suffering from sleep problems and who visited the sleep clinic. METHODS: Records of patients who visited the sleep clinic at the Tokyo Bay Urayasu Ichikawa Medical Centre at the age of 20 years or younger on their first visit were retrospectively examined, and their initial and final diagnoses were examined...

Executive functions are complex both in the cognitive operations involved and in the neural structures and functions that support those operations. This complexity makes executive function highly vulnerable to the detrimental effects of aging, brain injury, and disease, but may also open paths to compensation. Neural compensation is often used to explain findings of additional or altered patterns of brain activations by older adults or patient populations compared to young adults or healthy controls, especially when associated with relatively preserved performance...

BACKGROUND: Adolescent intermittent ethanol (AIE) exposure produces persistent impairments in cholinergic and epigenetic signaling and alters markers of synapses in the hippocampal formation, effects that are thought to drive hippocampal dysfunction in adult rodents. Donepezil (Aricept), a cholinesterase inhibitor, is used clinically to ameliorate memory-related cognitive deficits. Given that donepezil also prevents morphological impairment in preclinical models of neuropsychiatric disorders, we investigated the ability of donepezil to reverse morphological and epigenetic adaptations in the hippocampus of adult rats exposed to AIE...
