I knew a boy who had that condition. He had a shunt that drained a lot of the fluid out of his brain. He was a wizard at some subjects at school including drawing. He could watch a fast moving car on TV for a few minutes, then go into another room and draw a replica of the car. Some subjects he never mastered but the specialists told him Mum that the section of his brain that does those things was damaged. She was told that part of it loses tiny fragments like cracked egg shell. He was in his early teens when they convinced him to go into a wheelchair as he had lost his balance, his Mum was tiny ans he was a big lad. Sadly he passed away as the result of a heart attack.
