Thanks for asking the question Blackcat! I have been wondering the same, my DS11 scored in the 94 percentile for working memory, and in the 16 percentile for processing speed.

He is not 2e as far as I know. He does have some ADHD like symptoms at home but not at school. According to the Brown Attention Deficit Disorder Scale he is fine :-)

He has a very hard time putting pen to paper for writing exercises, even though he can verbally give detailed, comprehensive answers to the same questions. This means he is often to slow to complete his work at school, this has improved with time. He draws beautify, and his hand writing is quite neat. He can barely write (at all, like one or two letters per sheet of paper) with his left hand (he is right-handed), I find this interesting.

It has been recommended to us that we take him to a behavioral optometrist as a first step, which I have not done yet... I would love for someone to second this recommendation.

Best of luck in your search for answers!
