Background and Objectives: Preterm infants are at higher risk of neurodevelopmental impairment both at preschool and school ages, even in the absence of major neurological deficits. The early identification of children at risk is essential for early intervention with rehabilitation to optimize potential outcomes during school years. The aim of our study is to assess cognitive outcomes at preschool age in a cohort of low-risk very preterm infants, previously studied at 12 and 24 months using the Griffiths scales. Materials and Methods: Sixty-six low-risk very preterm infants born at a gestational age of <32 weeks were assessed at 12 and 24 months corrected age using the Griffiths Mental Development Scales (second edition) and at preschool age with the Wechsler Preschool and Primary Scales of Intelligence (third edition) (WPPSI-III). Results: At 12 and 24 months and at preschool age, low-risk very preterm infants showed scores within normal ranges with similar scores in males and females. A statistically significant correlation was observed in the general developmental quotient between 12 and 24 months; a further significant correlation was observed between the early cognitive assessments and those performed at preschool age, with a better correlation using the assessments at 24 months. Conclusion: The present study showed a favourable trajectory of cognitive development in low-risk very preterm infants, from 12 months to preschool age.

Autism spectrum disorder (ASD) and joint hypermobility (JH) are considered two different etiological and clinical entities that most often appear in childhood. Despite growing increased research showing a co-occurrence for both conditions, a link between them is rarely established in clinical settings, and the relationship between ASD and JH has not so far been completely investigated in all age groups of ASD children. This preliminary study examined a cohort of 67 non-syndromic ASD children aged 2–18 years (sex ratio M:F = 12:1) showing different degrees of cognitive impairment and autism severity, using the Beighton scale and its revised version. A total of 63% of ASD patients aged 2–4 years and 73% of ASD patients aged ≥5 years presented significant scores of hypermobility. No significant correlation was found comparing total laxity score and cognitive assessments and severity of autistic symptomatology (p > 0.05). The results suggest that JH could be considered as a clinical characteristic of ASD patients and it needs to be assessed in order to schedule a better rehabilitation program.

Perinatal stroke is related to possible differences in predisposing factors and outcomes between acutely and retrospectively diagnosed cases. In most cases, there are different risk factors and infections that could play an important role. Thus far, different clinical manifestations have been reported in children presenting with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), ranging from asymptomatic status to severe disease sustained by an immune-mediated inflammatory response. SARS-CoV-2 has been associated with severe neurological diseases including seizures and encephalitis in both adults and children. However, there are still few reports regarding the possible relation between SARS-CoV-2 infection of mothers during pregnancy and the neurologic outcome of the newborns. We described the case of a newborn diagnosed with a perinatal stroke, born at 35 weeks of gestation from a mother presenting with SARS- CoV-2 infection during the last months of pregnancy. We also added a brief review of the literature with similar cases. Close monitoring and early intervention in young children born to infected mothers would be highly recommended for the potential neurodevelopmental risk.

Hikikomori is a form of social withdrawal lasting more than 6 months with significant associated functional impairment. To date, numerous studies confirm the presence of this condition not only in Japan, where it was first described, but also globally abroad. This is an underestimated clinical condition, and it is emerging especially in adolescents and young adults, representing an increasing management problem for families and society. Prevalence ranges from 1.1% to 6.7%. Hikikomori can be associated with other neurodevelopmental disorders, such as Autism Spectrum Disorder (ASD). Indeed, ASD and hikikomori share numerous characteristics confirmed by functional neuroimaging studies that have highlighted in both conditions the presence of alterations in cerebral regions related to social functioning. We present a case report regarding the history of a 14-year-old girl with characteristics compatible with ASD and hikikomori. At present, there are no specific treatments approved for hikikomori in ASD patients. Further studies are necessary to understand the link between the two conditions, the boundary, and possible overlap.

Attention-Deficit/Hyperactivity Disorder (ADHD) may be associated with alterations in eye movements, which in turn may reflect dysfunctions in executive functions and sensorimotor integration processes. This review analyzed the pattern of oculomotor findings of pediatric populations diagnosed with ADHD with or without methylphenidate (MPH) treatment, with the aim of systematically describing the oculomotor abnormalities observed in affected children. A total of 24 studies were analyzed. The results showed that children with ADHD exhibit increased latency, a higher number of directional errors in prosaccade and antisaccade tasks, as well as intrusions during fixation and a higher frequency of microsaccades and involuntary blinks. Furthermore, studies involving the administration of MPH showed an improvement in oculomotor control, with a reduction in errors and a modulation of latency and oculomotor inhibition. These findings confirmed the potential role of oculomotor parameters as objective and non-invasive biomarkers for exploring the neurofunctional correlates of ADHD and for evaluating the effects of pharmacological treatment.
