Characteristics for the diagnosis of Autism Spectrum Disorder

Abstract

Introduction: autism Spectrum Disorder (ASD) is indeed a neurodevelopmental disorder whose exact cause is not yet fully understood. Symptoms can vary significantly among affected individuals, but generally include difficulties in communication and social interaction, as well as repetitive and restricted behaviors. Identification of early indicators and early diagnosis, as well as effective management of ASD, may lead to earlier and improved intervention in affected patients.Methods: a search for information on diagnostic indicators of ASD was conducted in Pubmed, Cochrane and clinicaltrials.org databases. Systematic reviews and meta-analyses were identified without considering publication status, reported results, last five years of publication and with language restriction to English, Spanish and Portuguese.Results: a total of 12 studies published between 2013 - 2023 were selected, and 7 systematic reviews and meta-analyses published between 2013 - 2021 that met the established inclusion criteria were included.Conclusion: diagnostic indicators of Autism Spectrum Disorder (ASD) in children are crucial for the family as a whole to lead a more age-appropriate life. ASD is increasingly common in society, but many are still unaware of the signs in their children, which delays detection and creates difficulties for everyone. Early intervention and appropriate support can significantly improve the prognosis of the disorder and help find the best treatment for the child
