We did suspect a possible expressive language issue - however we are a bilingual family,
It is possible to have more than one thing going on. There may well be an expressive language issue here.
I did wonder about stealth dyslexia - the visual assessment basically resulted in us being told he is working about 3 x harder than he should be - but there has been a definite improvement in terms of losing place, replacing words, skipping etc. It still happens on occasion, but generally when he's not wearing his glasses/is tired.
Blackcat what you say in terms of he just simply doesn't seem to know what to say/write rings true with me. I often feel like he has the vocabulary department of his brain, but the writing/planning part of his brain doesn't seem to be working together with the vocab? I don't know if that makes sense.
My nephew has been tested and has Aspergers. DS did a number of austistic-type stuff when he was younger, but a lot of it seemed sensory related (eye-contact, not liking hugs).
Often an SPD diagnosis by an OT shows you an incomplete picture. I'd want someone to evaluate for autism spectrum disorders as well as a full range of testing regarding reading comprehension and language fluency.
Not knowing what to say or write can be a language disorder, a social skills disorder, or both. Knowing exactly what skills are missing is vital because it tells you what to work on. I'd say to pursue the testing.
