Hi, Some adults could go on living with undiagnosed autism spectrum disorder (ASD) for most of their life facing social and work difficulties. However, receiving an ASD diagnosis later in life can be helpful, because it gives access to helpful services and support. It is challenging to make the diagnosis for an adult. Self assessment tests are a good start. Nevertheless, it is important to know that for ASD there is no cure, but many people find ASD an essential part of their identity and does not require treatment. A therapist, psychiatrist, neurologist can help ASD patients manage their symptoms. Managing the symptoms include: Autism education, therapy for work stress or feeling isolated, vocational rehab, and medication for anxiety if needed. Those recommendations also apply to the case of your child. It is easier to diagnose ASD in children too. The earlier the intervention could help the child feel better about himself and cope faster with his condition. Hope I have answered your question. Let me know if I can assist you further.
