He shares a lot of traits with my DS, who has a diagnosis of Asperger's Syndrome. He just about made it into the criteria for AS - the 'triad of impairments' - but he isnt the classic AS child that you see n paper - but then, not many children are. As is a real spectrum within the spectrum, iyswim. He has a brilliant imagination and loves metaphor, plays on words, humour etc. He isnt literal at all, and he doesn't have obssessions about things, really. But he lacks social imagination, and finds social interaction difficult.
HotheadPaisan, as you mention it (see my other thread!), I am looking into PDA. My DS has extreme demand avoidance, and this is actually much more of a difficulty for him than his more classically AS traits. It doesn't sound like the OP's son has such difficulties though?
Two thigs OP:
First and foremost you do not necessarily have to wait a year for assessment. I was on a 18 mth waiting list for ADOS. I phoned and phoned and emailed and wrote letters, urging them to bump him up as his difficulties at school were so extreme. In the end, they offered me it within a month (but in the meantime the lead a Paediatrician with specialism in ASD in my area assessed him and diagnosed him on the same day. He had already seen OT, SALT, CAMHS, advisory teachers and Ed psych, so she didnt see the need for him to go through the testing. In retrospect, the assessment would have been good and we may yet go back for it, but we knew what his problems were by that stage and needed a Statement , so I was just glad to get the diagnosis).
My point is, I have learned over the years to never, ever take anything a professional tells you about waiting lists or things 'not being worth it' seriously. Make a nuisance of yourself, show them you mean business, and you will usually get what you want and quickly. This worked with the OT (3 mth waiting list, saw me within a week), SALT (ditto), Clinical Psych (6 mth waiting list, within a month we had weekly appointments set up).
Second, don't necessarily be afraid of CAMHS. In my area they are benign but useless, but by agreeing to a few months of harmless play-based psychotherapy, we were able to show and prove that it was useless and not what DS needs. We were then able to get a referral to a much more eminent Psychologist out of borough, paid for by the L.A, because we proved by elimination this was what he needed.
I know it is daunting! Wish you luck.
