Background: Neuroinflammation seems to be involved in ADHD pathogenesis. Recently, in this regard, some evidence suggests the possibility of an autoimmune mechanism related to anti-Purkinje cell antibodies. The aim of this paper is to confirm this evidence searching for a possible specificity for some subtype of ADHD., Methods: We studied 112 consecutive drug-naïve Caucasian ADHD outpatients, who were attending their first psychiatric examination (91 males and 21 females; median age =108.14 months; sd=34.58 months). K-SADS interview and ADHD rating scale were used for a DSM 5 diagnosis of ADHD and subtype. WISCIII and a validated list of words were used to assess a possible dyslexia. Antibodies to Yo (Purkinje cell cytoplasmic antibody type 1 [PCA-1]) were detected by indirect immunofluorescence assay., Results: Forty-nine point one percent (55) of ADHD children were positive to Anti-Yo antibodies. A lower percentage than in previous studies. We found that in the Anti-Yo positive children, the subtype most represented was significantly the combined subtype. No significant relation was found with ADHD plus Dyslexia children., Conclusions: The number of ADHD subjects positive to Anti-Yo antibodies is less than in previous studies, but it remains interesting and it is more likely to find a positive child in the combined ADHD than in the other subtypes.

Background: Recent literature highlighted the relevance of parenting strategies and emotions in dealing with children with ADHD and showed that these dimensions were highly affected by the COVID-19 lockdowns. Thus, our research investigated the impact that the COVID-19 pandemic had on caregivers of children with attention deficit hyperactivity disorder (ADHD). We focused on the role of medications, children's age, and distance learning on changes in caregivers' emotions and parenting strategies., Methods: Nine hundred ninety-two caregivers completed an anonymous online questionnaire. The survey enquired caregivers about children's pharmacological therapy, difficulties in distance learning, and caregivers' parenting strategies and emotions before and during the lockdown., Results: Our results showed that caregivers experienced relevant difficulties in distance learning and that they felt more frustration emotions and employed more negative parenting strategies than before the pandemic. While pharmacological therapy was not a significant predictor of changes in neither positive nor negative parenting strategies, children's age and learning burden proved to predict caregivers' changes in positive parenting strategies. Moreover, our mediation analysis showed that the learning burden (e.g., homework increasing and children's reliance on caregivers) partially mediates the effect of age on changes in positive strategies. The older the children, the less the burden, and the less the change in positive strategies., Conclusions: These results describe lockdown's impact on caregivers' experience in dealing with children with ADHD and explain how they adapted to it by changing their parenting strategies.

Parasomnias usually present in childhood and resolve spontaneously. The diagnosis of non-rapid eye movement-related parasomnias is mainly based on clinical descriptors and can be challenging. Rapid eye movement-related parasomnias may index an underlying psychiatric disorder. Even if benign, parasomnias can affect quality of life. Pediatricians and child psychiatrists should be familiarized with these sleep disorders and suggest adequate sleep hygiene, avoidance of sleep deprivation, and regular bedtimes even on weekends as the first step in management of these disorders. Clinicians should pursue the opportunity for tailoring treatments and consider referral to a sleep expert when indicated., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2023 Elsevier Inc.
