My son Thomas was diagnosed with ADHD at age 7 and then Aspergers at 9 (though if school had been allowed to diagnose they woukld have done so at age 5!)
I feel strongly that an Ed psychologist should not be the one relied on for a diagnosis....i see them as being invaluable AFTER diagnosis as they can look at the 'big picture' of how the child manages from the moment they walk through the doors until they are back in your care.
Also, have just moved schools (april) due to the poor support/attitude towards SN generally at the previous school.
Basically leigh (age 7) has been demonstrating obvious ASD traits for nearly 2 years and all i got from the school was'Well he's nothing like Thomas'....so they refused to take me seriously. So i self-referred to the paed who diagnosed tom- and whilst she agreed that he was showing aspergers tendancies....that the school seemed to feel he was managing very well. So that was that.
However after just 2 days in the new school he was put on school action plus and the paed was contacted.
So i totally agree with the fact that you cannot 'rule out' aspergers 'just because the others with it are not at all like it'...however i do agree an assessment is a good idea as much of what you have described sound very familiar to me.
i'd love to say otherwise but because i have 2 extremely different boys - both somewhere on the spectrum ...
As far as 'what you say to the ed psychologist'
what i would do is list the kind of things you have on here that you notice and any strategies you have to use to ease his difficulties etc....with my 7 year old i have to invest alot of time with him to explain figures of speech (he is literal),explain how and when to apologise, how to wait for his turn in conversation, gradualy introduce 'end of activity' or change to a plan/routine,explain body language, he uses fingers to eat and i have to feed him spoon foods,i could list many other things....but will leave it there!
whereas tom well he is the walking encyclopaedia who's only irritation which fits the 'routines/need for sameness etc) is how t.v programmes change their graphics/music/channels etc and he gets annoyed with tv adverts which 'makekids think that their toy will do THAT.....'but in reality the toys are rubbish and are a real letdown.....hope that makes sense.he asks questions but has no interest in a reply....he cannot write stories from imagination...he bases all stories on playstation games he plays. lately he has become very angry and uses offensive language towards me- he also refers in an inappropriate sexual way to me too which is very hard to take as he 'luckily' doesn't do this at school so I get no help with this- if it happened at school then i'd get help. he also has no organisation skills ands though incredible long term memory- he has to have step by step guidance on everday things as he has terrible sequencing skills....though on paper he scores fantasticly if asked to sequence a picture story ...however struggles to get dressed
For me ....looking back this is how i've got here....
Always 'knew' he was 'unique/different'
I learnt about ADHD and decided that as Tom was nothing like another boy i knew with Aspergers that HE DID NOT HAVE ASPERGERS (!!!see i made that assumption too)
Also to be honest....had a fixed idea about autism so again this 'coloured' my view.
Medication for ADHD relieved the symptoms sufficiently to convince even the paed that maybe he didn't have aspergers.
Then he had a speech and language assesment....and the 'well hidden' diffulculties he had with language emerged.
i then 'just for fun' read up on aspergers and realised how similar it was to some of the ADHD stuff i'd read (and dyslexia...and dyspraxia....and semantic pragmatic disorder) .
so i read up on all these things and kept being drawn back to the aspergers ....as he has what they call the TRIAD of impairments....ie social,comminicative and imaginative impairments...AND finally i accepted that whilst i felt he was dyspraxic and ADHD....neither of those accomodated this triad totally.
Best way to explain is you can have a dyslexic child who is socially impaired but can play imaginatively...or a dyspraxic child who is socially skilled.....but an Asperger's child will be impaired in all 3 areas.....maybe only mildly and some of the impairment may be worse than the other.....
so....back to what you do now....READ READ READ - all you can. you will then hopefully end up reaching a point where you can 'pigeon hole' his difficulties....and don't forget the 'qualities' too...it's not all bad!!!
As well as 'hidden dissabilities' they come equipt with 'hidden talents' too!
ask me ANYTHING specifically....i do tend to ramble....so if you need more info....i'm better if you direct me!!!!
