Background: Lithium is the gold-standard treatment for Bipolar Disorder (BD) in both adults and adolescents, effectively managing mood episodes and reducing suicide risk. While its efficacy in neurotypical youth is well established, its use in adolescents with Autism Spectrum Disorder (ASD) and comorbid BD remains under-researched. Here, we present the protocol for a study aiming to evaluate the efficacy and tolerability of Extended-Release Lithium Salts in treating adolescents with BD and comorbid ASD compared to neurotypical BD patients. Methods: This longitudinal prospective naturalistic comparative study will enroll lithium-naïve adolescents aged 12–18 with BD, with or without comorbid ASD, from the Department of Child and Adolescent Psychiatry and Psychopharmacology. Participants will be followed for six months while receiving Extended-Release Lithium Salts treatment. Primary outcomes will include mood instability, suicidality, emotional dysregulation, and aggression, assessed through a range of clinical rating scales and diagnostic tools at baseline, three months, and six months. Secondary outcomes will focus on the safety and tolerability of Extended-Release Lithium Salts, with measures including side effect ratings, physical exams, and laboratory tests. Results: We hypothesize that Extended-Release Lithium Salts will demonstrate non-inferiority in treating BD symptoms in adolescents with comorbid ASD compared to those without ASD. Conclusions: This study is poised to fill a significant gap in the literature by providing critical data on the use of lithium for adolescents with BD and ASD. Findings will inform clinical practice and future research, potentially guiding more personalized treatment approaches for this complex and vulnerable population. [ABSTRACT FROM AUTHOR]

Background: Sleep is a complex phenomenon that affects several aspects of life, including cognitive functioning, emotional regulation, and overall well-being. Sleep disturbances, especially during adolescence, can negatively impact emotional regulation, making it a critical factor in targeting psychopathology. Methods: This study explores the interplay between emotional dysregulation (ED) and sleep patterns in a sample of 90 adolescent patients by means of self- and parent-rated clinical measures. Results: Our findings reveal a bidirectional relationship between ED and sleep problems. Adolescents with higher affective instability experience poorer sleep quality, while those with worse sleep quality exhibit higher internalizing problems. Additionally, emotional reactivity is associated with disrupted circadian rhythms. Conclusions: These results emphasize the significance of addressing sleep problems in the context of psychopathology treatment, potentially leading to improved outcomes. Further research is needed to determine the most effective treatment strategies, including nonpharmacological and pharmacological interventions. Understanding the intricate relationship between sleep problems and emotion regulation offers insights for more targeted and effective treatment approaches for youths struggling with ED.
