Maybe a long shot, maybe not?
My son is 7 and has had a shunt since he was 6 months old. He had a brain haemorrhage around birth (although he wasn't premature- just one of those unlucky things) and everything has been ticking over fine since.
He has developmental delay, and suffered a horrible seizure a few years ago, which he takes meds for now.
Recently he has been having a lot of headaches and vomiting in the mornings. CT scans are clear, so I just wondered if there were any other parents of shunted children here, or even parents themselves with hydrocephalus?
