Hi,
In 1969 my brother, as an infant, was born and diagnosed with hydrocephalus. As he was growing, he had frequent (every other year) surgeries to change the shunt, and distribute the excess fluids, but after he reached the age of about 12, his surgeries became fewer, about every 8 years or so, and they had routed the fluids into his stomach. His development and intelligence were not affected in the least. He was perfectly normal, and participated in sports. Being diagnosed early in life is key. In 2005, I'm sure they've even progressed further, and hopefully have better shunts, and fewer surgeries!
