IQ PLEASE HELP!! SIGNIFICANT DIFFERENCE BETWEEN VIQ AND PIQ

Xanadu
over 6 years ago

Hi

I'm really hoping someone can help me?

So I'm going forward for an ASD Diagnosis.  I am convinced that I have Aspergers.  I'm waiting on an appointment from [removed by moderator].
I'm 43 by the way so this is a kind of 'late diagnosis' and last year I got diagnosed with ADHD as well but ADHD doesn't quite explain the other stuff that is going on for me which now I am medicated shows much more!
So I paid privately for an HCPC reg Adult Educational Psychologist to test my IQ.  It's high and I knew it was but there is a problem.  There is significant discrepancy.  So in my verbal scores my results are in the 96th percentile which puts me in the 'very superior' category but there is a discrepancy of 21 points to my non verbal results which are on the 73rd percentile.
The EP says:

A difference between VIQ and PIQ of as much as 17 standard score points(in favour of former)  is relatively uncommon and would be found in only about 10% of the population.

My discrepancy is higher than 17 it's 21.  So I googled that exact statement and all that keeps coming up is 'learning disability' specifically HFA, Aspergers and something called NLD.  ADHD also gets mentioned but much less.
So I just want to know really would that discrepancy in IQ be typical for someone with Aspergers/Autism and what do you guys make of it.
Thanks.

    Hi, when I was 11 my VIQ was 120 and my PIQ was 76. No further testing was done. I have found out this is common in ASD - specifically what used to be called Asperger’s - now ASD with no language or intellectual impairment. 

    I have been diagnosed with ASD (Aspergers) and ADHD. This congnitve profile may point towards some right hemisphere dysfunction, as the right hemisphere is responsible for what is assessed in the PIQ. Quite likely you are right handed. 

    I have also noticed that I have slight weakness in my left body and face. The muscle tone in my face is less on the left with slightly drooling eye lid and slightly drooping mouth. I don’t have any academic evidence for this, but it has been reported by a lot of people with Asperger’s and correlates to the right hemisphere not working as it should. 


    NLD or NVLD is also characterised by a high VIQ and low PIQ - however it is not listed in the DSM V or ICD 11, so there are not any diagnostic criteria for it. This makes diagnosis challenging as it is not well defined. There is also a school of thought that NLD and Asperger’s are similar/the same but one described from a psychiatric perspective (Aspergers) and one from a psychological perspective (NLD). It’s been a while since I read the neuroimaging studies but they also share a significant number of anatomical differences in the brain if I remember correctly.

    Im desperate to chat with a psychologist about my cognitive profile and get it reassessed and find out why it was ignored when I was 11.

    I am a healthcare professional, but I do not specialise in mental health or neurodivergence/neuroscience so as a disclaimer it is likely I have come to some incorrect conclusions.
