This is fascinating to me. I was diagnosed with aqueductal stenosis at the age of six months and shunted. None of my neurosurgeons or any of my doctors have ever commented on the possibility of any cognitive damage that may have resulted from my Hydrocephalus. Despite the occasional blockage I lived a pretty typical childhood. I had an endoscopic third ventriculostomy around six years ago and feel like my memory has gotten worse since (my ventricles were pretty large by the time I went to hospital). I also suffered double vision after that surgery, which has since corrected itself. I was never allowed to be active as a kid - was always uncoordinated and clumsy. I have no idea whether that was due to the Hydro, or simply me being naturally clumsy. I wish I could blame my poor math skills on the Hydro rather than just choosing not to do my homework!
