COVID-19 quarantine: Psychological impact and support for children and parents
2021
In response to the coronavirus (COVID-19) pandemic, national governments have imposed urgent sanitary and social measures to control the spread of the virus. One such measure is quarantine, which involves restricting people’s movement through the isolation of infected or suspected infected individuals in order to reduce the risk of new infections. Research has shown that quarantine is a psychologically stressful experience. With respect to children, lack of school and interruptions to daily routines could have a negative impact on their physical and mental health. Parents may also pass their psychological distress to children and practice inappropriate parenting behaviors, which could contribute to the development of post-traumatic stress symptoms in children.
In order to prevent these negative outcomes, governments must carefully consider any their decision to impose quarantine and family social care services must work together with children’s mental health services to ensure that the experience is as tolerable and safe as possible.

The co-occurrence Oppositional Defiant Disorder (ODD) in children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) has been associated to difficulties in regulating adverse states, elevated functional impairment, deficits in Executive Functions and high risk for psychopathology. Recent studies have shown that ODD is a negative predictor of a positive response to methylphenidate (MPH) treatment for ADHD symptoms in children and adolescents and that patients with a diagnosis of comorbid ADHD and ODD are less likely to respond favorably to pharmacological treatment with MPH. We conducted a naturalistic study to understand the clinical characteristics of drug-naïve children and adolescents with ADHD that influence the response to MPH by measuring the effect on attention. Specifically, we investigated whether a single dose of MPH differently affects the performance of 53 children and adolescents with ADHD with or without ODD comorbidity. In addition, participant characteristics such as symptom severity, functional impairment, and associated behavioral and emotional symptoms at baseline were examined to better understand what aspects affect the response to MPH. We found that a single dose of MPH improved the attention of children and adolescents with ADHD without ODD more than those with comorbid ADHD and ODD, resulting in reduced reaction times. Our findings indicated that children and adolescents with comorbid ADHD and ODD and those with ADHD alone did not exhibit differences in measures of attention prior to taking MPH, nor in demographic variables (age, intelligence quotient, gender), clinical characteristics related to symptom severity, and adaptive behaviors. However, we observed differences between the two groups in certain behavioral aspects, including the Dysregulation Profile and disruptive behaviors. Assessing symptoms in combination with the presence of ADHD can be beneficial in determining which individuals would derive the greatest benefits from treatment.

Autism Spectrum Disorders
2020
A novel battery (BAFE; Valeri et al. 2015) was used in order to assess three executive function (EF) abilities (working memory, inhibition and shifting) in a sample of 27 intellectually able preschoolers with autism spectrum disorder (ASD) compared with 27 typically developing children matched on age and nonverbal IQ. Differences in EF skills were analyzed in participants with distinct ASD symptom severity. Children with ASD performed worse than typical controls on both set-shifting and inhibition, but not on visuo-spatial working memory. Additionally, children with more severe ASD symptoms showed a worse performance on inhibition than children with milder symptoms. These results confirm the presence of EF deficits and highlight a link between ASD symptoms and EF impairments in preschool age.

Cross-sectional investigation of insulin resistance in youths with autism spectrum disorder. Any role for reduced brain glucose metabolism?
2021
The autism spectrum disorder (ASD) is an etiologically heterogeneous disorder. Dysfunctions of the intermediate metabolism have been described in some patients. We speculate these metabolic abnormalities are associated with brain insulin resistance (IR), i.e., the reduced glucose metabolism at the level of the nervous central system. The Homeostasis model assessment of insulin resistance (HOMA-IR) is very often used in population studies as estimate of peripheral IR and it has been recently recognized as proxy of brain IR. We investigated HOMA-IR in 60 ASD patients aged 4–18 years and 240 healthy controls, also aged 4–18 years, but unmatched for age, sex, body weight, or body mass index (BMI). At multivariable linear regression model, the HOMA-IR was 0.31 unit higher in ASD individuals than in controls, after having adjusted for sex, age, BMI z-score category, and lipids that are factors known to influence HOMA-IR. Findings of this preliminary study suggest it is worth investigating brain glucose metabolism in larger population of patients with ASD by using gold standard technique. The recognition of a reduced glucose metabolism in some areas of the brain as marker of autism might have tremendous impact on our understanding of the pathogenic mechanisms of the disease and in terms of public health.

Examining tolerability, safety, and blinding in 1032 transcranial electrical stimulation sessions for children and adolescents with neuropsychiatric and neurodevelopmental disorders
2025
The present study first extensively evaluated the tolerability, safety, and blinding of transcranial direct current stimulation (tDCS) and transcranial random noise stimulation (tRNS) in paediatric clinical populations, composed of 92 children and adolescents (54 females, age range: 8–17 years), involving 1032 sessions across neuropsychiatric (i.e., anorexia nervosa) and neurodevelopmental (i.e., attention deficit and hyperactivity disorder, developmental dyscalculia) conditions. It compared adverse events (AEs) occurrence between active and sham transcranial electrical stimulation (tES) conditions (i.e., 528 active vs. 504 sham sessions) as well as tDCS and tRNS (i.e., 772 tDCS sessions vs. 260 tRNS sessions), while considering demographic and emotional-behavioural factors. Results showed tES safety with no “moderate” or “severe” AEs reported; about 77% of sessions were AE-free, supporting tES use in these populations. Itching was the most common symptom, and active sessions were found to be more likely to induce AEs compared to sham sessions. Notably, tRNS had a higher AE likelihood than tDCS, possibly due to experimental differences. In the current study, demographic and emotional-behavioural variables did not significantly affect AEs. Blinding procedures were moderately effective, with about half of participants correctly identifying their condition. As indicated in prior studies, tRNS seems to better preserve blinding integrity. In conclusion, this study provides comprehensive insights into tES tolerability and safety in paediatric clinical populations, emphasizing the need for further AEs exploration in tES and blinding procedure refinement in future research.

Parent-mediated intervention is widely used for pre-schoolers with autism spectrum disorder (ASD). Previous studies indicate small-to-moderate effects on social communication skills, but with a wide heterogeneity that requires further research. In this randomized controlled trial (RCT), cooperative parent-mediated therapy (CPMT) an individual parent coaching program for young children with ASD was administered to preschool children with ASD. All children received the same low-intensity psychosocial intervention (LPI) delivered in community settings, to evaluate the potential additional benefit of CPMT. Thirty-four participants with ASD (7 females; 27 males; aged 2, 6, 11 years) and their parents were included in the trial. The primary blinded outcome was social communication skills, assessed using the ADOS-G social communication algorithm score (ADOS-G SC). Secondary outcomes included ASD symptom severity, parent-rated language abilities and emotional/behavioral problems, and self-reported caregiver stress. Evaluations were made at baseline and post-treatment (at 6 months) by an independent multidisciplinary team. Results documented that CPMT showed an additional benefit on LPI with significant improvements of the primary blinded outcome, socio-communication skills, and of some secondary outcomes such as ASD symptom severity, emotional problems and parental stress related to parent–child dysfunctional interaction. No additional benefit was found for language abilities. Findings of our RCT show that CPMT provide an additional significant short-term treatment benefit on ASD core symptoms, when compared with active control group receiving only LPI.

Restrictive eating disorders in children and adolescents: a comparison between clinical and psychopathological profiles
2021
Purpose
DSM-5 describe three forms of restrictive and selective eating: Anorexia Nervosa-Restrictive (AN-R), Anorexia Nervosa-Atypical (AN-A), and Avoidant/Restrictive Food Intake Disorder (ARFID). While AN is widely studied, the psychopathological differences among these three diseases are not clear. The aim of this study was to (i) compare the clinical features of AN-R, AN-A, and ARFID, in a clinical sample recruited from a specialized EDs program within a tertiary care children’s Hospital; (ii) identifying three specific symptom profiles, to better understand if restrictive ED share a common psychopathological basis.
Methods
Data were collected retrospectively. Psychometric assessment included: the Children’s Depression Inventory (CDI), the Multidimensional Anxiety Scale for Children (MASC), the Child Behavior Checklist (CBCL), and the Eating Disorder Inventory-3 (EDI-3).
Results
A final sample of 346 children and adolescent patients were analyzed: AN-R was the most frequent subtype (55.8%), followed by ARFID (27.2%) and AN-A (17%). Patients with ARFID presented different features from AN-R and AN-A, characterized by lower weight and medical impairment, younger age at onset, and a frequent association with separation anxiety and ADHD symptoms. EDI-3 profiles showed specific different impairment for both AN groups compared to ARFID. However, no differences was detected for items: ‘Interpersonal Insecurity’, “Interoceptive Deficits”, “Emotional Dysregulation”, and “Maturity Fears”.
Conclusions
Different ED profiles was found for the three groups, but they share the same general psychopathological vulnerability, which could be at the core of EDs in adolescence.

Background
Anxiety disorders (ADs) are common among children and adolescents and frequently co-occur with specific learning disorder (SLD). Approximately 20% of children with SLD meet criteria for ADs, while those with anxiety are six times more likely to have a premorbid SLD. The strong relationship between premorbid SLD and ADs underscores the importance of examining developmental trajectories and manifestations of neuropsychiatric conditions like ADs, particularly when SLD is present. In this context, this study investigates the clinical profiles of children and adolescents with a first diagnosis of an AD and a history of SLD compared to those with a first diagnosis of an AD without a history of SLD. The analysis focuses on various clinical characteristics, including developmental history, demographic aspects, age of anxiety onset, global functioning, types of ADs, self-report anxiety and depressive symptoms, and adaptive behavior. Additionally, the study aims to explore the relationship between anxiety symptoms and depressive symptoms, adaptive behavior, and age.
Methods
We conducted a cross-sectional, retrospective study with 78 participants from the Child and Adolescent Neuropsychiatry Unit, divided into two groups: those with ADs alone (Group AD,
n
= 42) and those with both ADs and premorbid SLD (Group AD + SLD,
n
= 36). We collected data on developmental history, demographic information, age of anxiety onset, global functioning, anxiety and depressive symptoms, and adaptive behavior.
Results
Our findings revealed that Group AD experienced more stressful life events and had higher cognitive levels, whereas Group AD + SLD showed a greater impairment in global functioning. Notably, Group AD exhibited lower social adaptive behavior and higher self-reported anxiety and depressive symptoms than Group AD + SLD, possibly indicating a greater awareness of their emotional distress.
Conclusions
These findings highlight the impact of premorbid neurodevelopmental disorders into clinical manifestations of psychopathological symptoms. In particular, results underline the importance of developing tailored clinical interventions for children with co-occurring ADs and learning difficulties, focusing more on their emotional awareness to better address the unique challenges posed by the comorbidity.

In the last decades, the conceptualization of schizophrenia has dramatically changed, moving from a neurodegenerative process occurring in early adult life to a neurodevelopmental disorder starting be-fore birth, showing a variety of premorbid and prodromal symptoms and, in relatively few cases, evolving in the full-blown psychotic syndrome. High rates of co-occurring different neurodevelopmental disorders such as Autism spectrum disorder and ADHD, predating the onset of SCZ, and neurobio-logical underpinning with significant similarities, support the notion of a pan-developmental disturbance consisting of impairments in neuromotor, receptive language, social and cognitive development. Con-sidering that many SCZ risk factors may be similar to symptoms of other neurodevelopmental psychi-atric disorders, transition processes from child & adolescent to adult systems of care should include both high risk people as well as subject with other neurodevelopmental psychiatric disorders with different levels of severity. This descriptive mini-review discuss the need of innovative clinical approaches, re-considering specific diagnostic categories, stimulating a careful analysis of risk factors and promoting the appropriate use of new and safer medications.

This perspective review aims to explore the potential neurobiological mechanisms involved in the application of transcranial Direct Current Stimulation (tDCS) for Down syndrome (DS), the leading cause of genetically-based intellectual disability. The neural mechanisms underlying tDCS interventions in genetic disorders, typically characterized by cognitive deficits, are grounded in the concept of brain plasticity. We initially present the neurobiological and functional effects elicited by tDCS applications in enhancing neuroplasticity and in regulating the excitatory/inhibitory balance, both associated with cognitive improvement in the general population. The review begins with evidence on tDCS applications in five neurogenetic disorders, including Rett, Prader-Willi, Phelan-McDermid, and Neurofibromatosis 1 syndromes, as well as DS. Available evidence supports tDCS as a potential intervention tool and underscores the importance of advancing neurobiological research into the mechanisms of tDCS action in these conditions. We then discuss the potential of tDCS as a promising non-invasive strategy to mitigate deficits in plasticity and promote fine-tuning of the excitatory/inhibitory balance in DS, exploring implications for cognitive treatment perspectives in this population.
