Do You Think You or Your Child Might Be Autistic?
Many people begin to notice differences in communication, social interaction or behaviour long before seeking advice.
You may be considering a private Autism assessment if you or your child:
- communicate differently from others
- find social situations challenging
- prefer routine and predictability
- have strong or focused interests
- experience sensory sensitivities
- feel overwhelmed in busy environments
Every individual is different, and these experiences do not necessarily mean Autism. However, an assessment can provide understanding, validation and clear next steps.
