There is a triad of symptoms that sound a lot like what you may be experiencing. It could be a great thing that they find this early, means they are really looking and not blowing things off, less chance you lose functionality. NPH is often missed, even in older populations.

It is young. Not sure how they would differentiate between having mild hydrocephalus all your life and NPH, or it makes a difference in treatment.
