Dysgraphia shows up mostly in handwriting but its a neurological misfire in the brain, part of the dyslexia family. Poor spelling is another very common symptom, that luckily DS does not have.
DS does use a laptop, but all that does is save his hand from the pain and make what he writes legible. The other big symptom - difficulty thinking and writing simultaneously hasn't gone away, and he still has the coordination problems.
The upshot is that his typing speed is slower than most people's handwriting speed, especially when not copy-typing, and he struggles to remember the plan for the rest of the paragraph as he types / writes. So, its all a bit inefficient. His verbal answers are much fuller than his written answers which can be very terse.
It was frustrating for him at primary school, until the diagnosis when he was 10, especially as the year 6 class teacher / senco decided that he must just be lazy when he writes.
