Thank you. There was nothing the report about forwards vs. backwards. I should ask him to try some numbers myself and see if I notice if he's struggling with one or the other.
One of the cranial nerves in his brain was paralyzed due to blunt force trauma and concussion, and it took about 6 months for the nerve to heal enough for his eyes to become completely aligned. So that sounds about right for recovery from a brain injury. During the first testing (about 4 months after the brain injury), the psych did a whole bunch of other tests and DS had absolutely wretched scores for fine motor ability (Grooved Pegboard), like below the .01 percentile. So we suspect that the brain injury made his preexisting condition (DCD) even worse. Strangley he scored very high on subtests like matrix reasoning even though he probably had some double vision. And block design wasn't bad either but quite a bit lower than the other PR subtests.
