GABAergic interneurons play important roles in cortical circuit development. However, there are multiple populations of interneurons and their respective developmental contributions remain poorly explored. Neuregulin 1 (NRG1) and its interneuron-specific receptor ERBB4 are critical genes for interneuron maturation. Using a conditional ErbB4 deletion, we tested the role of vasoactive intestinal peptide (VIP)-expressing interneurons in the postnatal maturation of cortical circuits in vivo. ErbB4 removal from VIP interneurons during development leads to changes in their activity, along with severe dysregulation of cortical temporal organization and state dependence...

Drooling of saliva is common in children with physical, intellectual and learning disability, and with poor neuromuscular coordination and oral control.(1) It can cause skin breakdown, damage to clothes and equipment and psychosocial problems for the child and family. For many years, glycopyrronium has been prescribed off-label using the injection solution given orally or tablets crushed and suspended in water, or as unlicensed products that were imported or manufactured as pharmaceutical specials.(2,3) In January 2017, a glycopyrronium oral solution (Sialanar-Proveca Limited) became available in the UK as the first licensed product for the treatment of severe drooling (sialorrhoea) in children and adolescents aged 3 years and older with chronic neurological disorders...

According to recent WHO reports, alcohol remains the number one substance used and abused by adolescents, despite public health efforts to curb its use. Adolescence is a critical period of biological maturation where brain development, particularly the mesocorticolimbic dopamine system, undergoes substantial remodeling. These circuits are implicated in complex decision making, incentive learning and reinforcement during substance use and abuse. An appealing theoretical approach has been to suggest that alcohol alters the normal development of these processes to promote deficits in reinforcement learning and decision making, which together make individuals vulnerable to developing substance use disorders in adulthood...

Adolescence is accompanied by the maturation of several stress-responsive areas of the brain including the amygdala, a key region for the acquisition and expression of conditioned fear. These changes may contribute to the development of stress-related disorders in adolescence, such as anxiety and depression, and increase the susceptibility to these psychopathologies later in life. Here, we assessed the effects of acute restraint stress on fear learning and amygdala activation in pre-adolescent and adult male rats...

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD), as one of the most common neurological disorders in children and adolescents, is characterized by decentralization, slow learning, distraction and hyperactivity. Studies have shown that in addition to medication, neurofeedback training can also be used to partially control the brain activity of these patients. METHODS: In this study, using the brain signals processing before and after the treatment in 10 children treated by neurofeedback, the changes were evaluated by non-parametric statistical analysis and impact of neurofeedback on brain frequency bands was investigated...

BACKGROUND: There are no consistent predictors of treatment outcome in paediatric obsessive-compulsive disorder (OCD). One reason for this might be the use of suboptimal statistical methodology. Machine learning is an approach to efficiently analyse complex data. Machine learning has been widely used within other fields, but has rarely been tested in the prediction of paediatric mental health treatment outcomes. OBJECTIVE: To test four different machine learning methods in the prediction of treatment response in a sample of paediatric OCD patients who had received Internet-delivered cognitive behaviour therapy (ICBT)...

Little has been reported about how to improve health care access and delivery for adolescents and adults with autism spectrum disorder. To understand the contributions to the health disparities in the autism spectrum disorder population, we conducted two independent research approaches to learn about current medical needs. A retrospective chart review was performed to evaluate medical comorbidities and medication use. A focus group was also created to address barriers faced in providing medical care. Of 126 charts reviewed, 49% (n = 62) had intellectual disability, 49% (n = 62) had attention-deficit hyperactivity disorder, 52% (n = 65) had anxiety, 41% (n = 52) had obesity, 31% (n = 39) with a history of aggressive behavior, 31% (n = 31) had depression, 22% (n = 28) had seizures, and 9% (n = 11) had hypertension...

Borderline personality disorder (BPD) is common in clinical practice. Psychotherapy is the treatment of choice, and mentalization-based treatment (MBT) is one of the empirically supported treatments that are currently available. For adults, two variants of MBT (MBT day hospital [MBT-DH] and MBT intensive outpatient [MBT-IOP]) have been developed and empirically evaluated. The authors review research on the development, efficacy, and implementation of MBT. In conclusion, the authors focus on the implementation of treatment programs for BPD patients...

Executive functions are often affected in autism spectrum disorders (ASD). The underlying biology is however not well known. In the DSM-5, ASD is characterized by difficulties in two domains: Social Interaction and Repetitive and Restricted Behavior, RRB. Insistence of Sameness is part of RRB and has been reported related to executive functions. We aimed to identify differences between ASD and typically developing (TD) adolescents in Event Related Potentials (ERPs) associated with response preparation, conflict monitoring and response inhibition using a cued Go-NoGo paradigm...

Introduction: Adolescence and young adulthood are periods of continued biological and psychosocial maturation. Thus, there may be deleterious effects of consuming large quantities of alcohol on neural development and associated cognition during this time. The purpose of this mini review is to highlight neuroimaging research that has specifically examined the effects of binge and heavy drinking on adolescent and young adult brain structure and function. Methods: We review cross-sectional and longitudinal studies of young binge and heavy drinkers that have examined brain structure (e...

BACKGROUND: Robot-assisted gait therapy is increasingly being used in pediatric neurorehabilitation to complement conventional physical therapy. The robotic device applied in this study, the Lokomat (Hocoma AG, Switzerland), uses a position control mode (Guidance Force), where exact positions of the knee and hip joints throughout the gait cycle are stipulated. Such a mode has two disadvantages: Movement variability is restricted, and patients tend to walk passively. Kinematic variability and active participation, however, are crucial for motor learning...

Alcohol-related cues can evoke explicit and implicit motivation to drink alcohol. Concerning the links between explicit and implicit motivation, there are mixed findings. Therefore, we investigated both concepts in 51 healthy 18- to 19-year-old males, who are less affected by neuropsychological deficits in decision-making that are attributed to previous alcohol exposure than older participants. In a randomized crossover design, adolescents were infused with either alcohol or placebo. Self-ratings of alcohol desire, thirst, well-being and alcohol effects comprised our explicit measures of motivation...

The health problems related to the nervous system are on rise in young infants leading to high mortality amongst this age group. A chronic medical condition (CC) is present in this age group to the tune of 10-20%. We searched the electronic database PubMed for pre-clinical as well as clinical controlled trials reporting variable chronic conditions especially in pediatric patients. Most of these reports revealed that type 1 diabetes mellitus is the most common CC in young infants. In female patients, metabolic control is often disturbed during CC in this age group...

OBJECTIVES: One of the major challenges facing psychiatry is how to incorporate biological measures in the classification of mental health disorders. Many of these disorders affect brain development and its connectivity. In this study, we propose a novel method for assessing brain networks based on the combination of a graph theory measure (eigenvector centrality) and a one-class support vector machine (OC-SVM). METHODS: We applied this approach to resting-state fMRI data from 622 children and adolescents...

BACKGROUND: Exposure to adverse childhood experiences (ACE) and cognitive deficits are both prevalent in psychosis. While it has been repeatedly demonstrated that ACE contribute to cognitive dysfunctions, the specific nature of this contribution remains elusive. Recent evidence suggests that types of adversities during critical periods have deleterious effects on brain structures that are important for cognitive functioning. The present study sought to clarify which types of adversities experienced at which time during development aggravate cognitive deficits in psychosis...

Having a depressed mother is one of the strongest predictors for developing depression in adolescence. Given the role of aberrant reward processing in the onset and maintenance of depression, we examined the association between mothers' and their daughters' neural response to the anticipation of reward and loss. Fifteen non-depressed mothers with a history of recurrent depression and their never-disordered daughters, and 23 mothers without past or current depression and their never-disordered daughters, underwent fMRI while performing the monetary incentive delay (MID) task...

Individuals with autism spectrum disorders (ASD) are increasingly entering institutions of higher education. However, many are not prepared for the academic and social demands of postsecondary environments. Although studies have evaluated academic and social interventions for children and adolescents with ASD, little research exists on the college population. The current study utilized a multiple baseline across participants design to evaluate the effectiveness of a writing learning strategy on the writing performance of three college students with ASD...
