Social cognition in two brothers with Becker muscular dystrophy: an exploratory study revealing divergent behavioral phenotypes.

BACKGROUND AND OBJECTIVE: Only few studies investigated social cognition in Becker muscular dystrophy (BMD). However, brain dystrophin deficiency could be a neural substrate for cognitive, emotional, and neuropsychological features in BMD. METHODS: We compared interoceptive accuracy and interpersonal comfort distance in two brothers with BMD presenting with the same genetic deletion and a healthy control. When possible, we collected neuropsychological and psychopathological assessments. RESULTS: Our BMD patients were significantly different in interoceptive accuracy, with patient 1 being extremely accurate and patient 2 being significantly less accurate than his brother but more accurate than the control. Interestingly, they presented opposite patterns of interpersonal distance. Patient 1 was comfortable with very short interpersonal distance (≤50 cm from the confederate/object) vs the control and patient 2. By contrast, patient 2 preferred larger distance vs the control and patient 1. Patient 1 also presented difficulties in social and emotional skills on the psychopathological assessment. CONCLUSIONS: We are aware this is a small sample; nonetheless, this is also the first description of such aspects in BMD and the first report ever of such divergent behavioral pattern. As impaired social cognition affects the quality of life and social relationship, further studies are needed for a closer understanding of involved mechanisms.

A narrative review of the use of a cutting-edge virtual reality rehabilitation technology in neurological and neuropsychological rehabilitation.

BACKGROUND: Virtual reality (VR) interventions have been increasingly used in the rehabilitation of a wide range of neurological and neuropsychological dysfunctions. Findings of previous reviews showed positive and promising effects of VR-based interventions. However, they summarized findings on VR-based intervention carried out through different VR systems and tasks. OBJECTIVE: We carried out a narrative review with the aim of qualitatively synthesising the results of previous studies that used specific VR systems, i.e. the Khymeia -Virtual Reality Rehabilitation System, for treatment purposes. METHODS: We searched the literature in various databases (i.e. EMBASE, Web of Science, SCOPUS, PubMed and PubMed Central) for studies published until November 23, 2023. RESULTS: 30 studies were selected. The VRRS was used for neuromotor rehabilitation only in 13 studies, for cognitive rehabilitation in 11 studies, and for both neuromotor and cognitive rehabilitation in six studies. The study design was heterogeneous including 15 randomised controlled trials. CONCLUSION: After discussing each study according to the type of rehabilitation we concluded that the use and efficacy of VRRS rehabilitative intervention for increasing the neurological and neuropsychological functioning of patients are promising but more evidence is needed to make a comparison with conventional treatment. Future studies should also include long-term follow-up as well as cost-effectiveness analysis.

Factors associated with pharmacological treatment in children with attention-deficit/hyperactivity disorders: a retrospective study of a series of 77 cases in a single third-level reference Centre in Apulia region.

BACKGROUND: The present study analysed data on children and adolescents with a diagnosis of attention-deficit/hyperactivity disorder (ADHD) who were referred to the ADHD reference centre of Scientific Institute IRCCS E. Medea (Brindisi, Italy) for ADHD pharmacotherapy initiation and monitoring overtime. The main aim of the study was to examine differences in pharmacological treatment status (i.e., treatment continuation vs discontinuation) between patients. METHODS: Seventy-seven children and adolescents (mean age at pharmacotherapy initiation = 9.5, standard deviation = 2.6) with ADHD received drugs treatment for ADHD at the reference center between January, 2013 and May, 2022. Demographic and clinical data were obtained from the Italian Registry for ADHD and medical records. Child Behavior Checklist (CBCL) available data were used. RESULTS: Pharmacological treatment status was examined for patients (n = 63) with at least 12 months of follow-up after the first pharmacological treatment for ADHD. After starting pharmacotherapy treatment, 77.8% (n = 49) patients were still on treatment whereas 22.2% (n = 14) discontinued it. No between group difference were observed in demographic and clinical data except for the intelligence quotient/intellectual disability and rule-breaking behavior (n = 40). CONCLUSIONS: This study stressed the need of periodical assessments, monitoring difficulties with treatment and/or reasons for poor treatment compliance to provide individualized care.

Pain assessment in autism: updating the ethical and methodological challenges through a state-of-the-art review.

Sensory features of autism include hypo- or hyper-reactivity to pain; however, previous studies on pain in autism lead to conflicting results. Here, we present the state of the art and the methodological challenges concerning pain perception in autism, focusing on studies that used standardized protocol as Quantitative Sensory Testing (QST) to measure perception. Despite there are still scant evidences found with the use of QST, they have challenged the presumed hyposensitivity to pain in autisms, which emerged from parents' reports. Both, peripheral and central mechanisms, have been found involved in typical features of perception in autism. Nonetheless, evidences with controlled protocols are still scarce, and even scarcer are studies focused on children. Overall, complex ethical challenges have to be overcome in order to collect subjective and objective measures from autistic children. With heterogeneous neurodevelopmental features, or intellectual disability, novel or modified protocols are needed.

Coping, stress and negative psychological outcomes in parents of children admitted to a pediatric neurorehabilitation care unit.

BACKGROUND: Parents' attitudes and psychological adjustment during their child's hospitalization in a pediatric neurorehabilitation care unit are key aspects for the child's adherence to care and the impact of the disease. AIM: The aim of this study was to examine the relationship between parenting stress, coping style, and negative psychological outcomes in families of children admitted for the first time to a pediatric neurorehabilitation care unit. DESIGN: This is an observational study. SETTING: Pediatric neurorehabilitation care unit. POPULATION: One hundred twenty-four parents of children diagnosed with neurodevelopmental or neurological conditions. METHODS: Parents completed standardized questionnaires assessing parenting stress, coping style, anxiety and depressive symptoms. RESULTS: We found that parents of children with neurodevelopmental conditions showed more emotion-focused coping strategies (P=0.016) and depressive symptoms (P=0.01) compared with parents of children with neurological conditions. Hierarchical regression analyses showed that emotion- and avoidance-oriented coping style and socioeconomic status are crucial factors in the adjustment process of parents of children with neurodevelopmental conditions. By contrast, parenting stress and child difficulties were the most significant predictors of negative psychological outcomes in parents with neurological conditions. CONCLUSIONS: This study sought to develop more understanding of the relationship among parenting stress, coping, and anxiety or depressive symptoms in parent of children hospitalized in a pediatric neurorehabilitation care unit. We suggest that examining parents may increase our understanding of the interplay between child and parent functioning in families with children admitted for the first time to a pediatric neurorehabilitation care unit. CLINICAL REHABILITATION IMPACT: Identify these predictors might help professionals to develop screening procedures to identify parent at high risk for anxiety or depression, and to conduct early interventions to reduce uncertainty and maladaptive coping strategies that may influences rehabilitation process.
