Early Intervention Strategies in Williams Syndrome: A Case Report of Multimodal Therapeutic Approach in a 3-Year-Old Child

Williams syndrome (WS) is a rare genetic disorder characterized by distinctive facial features, cardiovascular abnormalities, and a unique neurocognitive profile, for which early intervention is crucial in optimizing developmental outcomes. We report the case of a 3-year-old female diagnosed with WS who presented with delayed language development, characteristic facial features, and cardiovascular anomalies. The child exhibited the typical WS cognitive behavioural profile, with relative strengths in social interaction and expressive language alongside marked deficits in non-verbal problem-solving and attention. A comprehensive multimodal intervention was implemented, incorporating speech therapy, behavioural modifications, and structured play activities facilitated by an adult. Following intervention, notable improvements were observed in social interactions with peers and in attention span during structured tasks. This case underscores the importance of early identification and individualized, comprehensive intervention strategies tailored to the specific cognitive and behavioural profile of WS in improving developmental outcomes in rare genetic disorders.
