Advice - first appointment: what to expect?

Julia21

hello - my son, who is 20, has his first triage appointment at the autism centre this week.

Letter advises it'll take about an hour and is with 2 clinicians - an autism specialist nurse and psychologist I think. If they think he has autism he'll then be put on waiting list for full assessment.

I'm just wondering what is likely to help during this hour assessment? Letter advises they may refer him onwards or advise he doesn't have autism. Just wondering how that decision is made? Son has epilepsy and quite severe anxiety - he wanted me in room with him but they've advised best if he goes in alone. I'd like to give him some idea of what to expect to help calm his nerves but am a bit stuck as no info on letter and I don't know anyone who's been to similar previously. He also masks very well for short periods and am just wondering if they'll be able to detect that at this initial assessment?

Any advice or tips very welcome. Many thanks in advance
