What is Autism?
Autism is a serious developmental disorder that impairs the ability to communicate and interact. Autism spectrum disorder impacts the nervous system and affects the overall cognitive, emotional, social and physical health of the affected individual.
The range and severity of symptoms can vary widely. Common symptoms include difficulty with communication, difficulty with social interactions, obsessive interests and repetitive behaviours.
Early recognition, as well as behavioural, educational and family therapies may reduce symptoms and support development and learning.
