Social communication in young children with sex chromosome trisomy

Children with SCT have an increased vulnerability for adverse neurobehavioral outcomes and an increased risk for neurocognitive difficulties in the language and communication domain. This vulnerability starts from a young age and may increase when children get older. Neurocognitive functions within the language and communication domain serve as early markers of at-risk pathways with unfavorable neurobehavioral outcomes. These findings come with important clinical implications for the SCT population andwill ideally fuel the implementation of early monitoring, and implementation and development of preventive support and intervention.
