Autism is a prevalent developmental disorder that combines repetitive behaviours, social deficits and language abnormalities. The present study aims to assess the autistic subjects using DSM IV-TR criteria followed with the analysis of neurotransmitters, biochemical parameters, oxidative stress and its ions in two groups of autistic subjects (group I < 12 years; group II ≥ 12 years). Antioxidants show a variation of 10% increase in controls compared to autistic age < 12 years. The concentration of pyruvate kinase and hexokinase is elevated in controls approximately 60% and 45%, respectively, with the significance of 95 and 99%. Autistic subjects showed marked variation in levels of neurotransmitters, oxidative stress and its related ions. Cumulative assessment of parameters related to biochemical markers and neurotransmitters paves the way for autism-based research, although these observations draw interest in an integrated approach for autism.

Background/objectives: Tic disorders are neurodevelopmental conditions often associated with comorbidities like attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Our aims were: (a) in a sample of youth with tic disorders to explore the clinical and psychopathological characteristics of different phenotypes based on the presence of comorbid ADHD and/or ASD and gender; (b) in a subgroup of patients treated with Aripiprazole, to evaluate symptoms variation over time and to identify potential predictors of response.
Methods: A total of 95 subjects with tic disorders (age range 6 to 17.

Background: Currently, there is a need for approaches to understand and manage the multidimensional autism spectrum and quantify its heterogeneity. The diagnosis is based on behaviors observed in two key dimensions, social communication and repetitive, restricted behaviors, alongside the identification of required support levels. However, it is now recognized that additional modifiers, such as language abilities, IQ, and comorbidities, are essential for a more comprehensive assessment of the complex clinical presentations and clinical trajectories in autistic individuals.

Communication can be a challenge for a significant minority of the population. Those with intellectual disability, autism, or Stroke survivors can encounter significant problems and stigma in their communication abilities leading to worse health and social outcomes. SpeechMatch (https://www.

The folate cycle has been implicated in the pathophysiology of autism due to its role in the glutathione oxidative stress pathway, amino acid and DNA methylation reactions, and neurotransmitter synthesis pathway. Previous research on folinic acid supplementation in autistic children has suggested potential benefits. The primary aim of this pilot study was to determine the safety, feasibility and efficacy of oral folinic acid in improving communication and behaviour in autistic children.
