As someone living with hydrocephalus for almost 40 years and as the p.r. director for the Hydrocephalus Support Group/Seattle, I take issue w/Mr. Ratey's definition of hydrocephalus and how his misconceptions of the condition are presented here as fact. In fact, they are fiction. There are millions of us who live very full lives with little or no mental impairment from hydrocephalus or having a shunt. Sadly, there are still those, like Mr. Ramey, who insist on perpetuating myths and misconceptions of what hydrocephalus is and how incompatable it is with a functional life!
