Hi ram
At the top of my list for a neurosurgeon in the Seattle area woulld be Dr. Timothy Steege. His main office is in the Heath Building next to Swedish Hosp, but he also has other offices in Ballard and Bremerton. If the main office is short of openings, try one of his other offices.
Dr Steege is highly experienced, listens to the patient and explains things in a way that's understood.
If a family member or myself needed a neurosurgeon he'd be the first one that I'd call. I know that he's one of the doctor's that's called in on the complicated cases.
Joef is right as far as neurosurgeries go, it's not considered a big deal, but you do want a doctor that is experienced in placement of the shunts. No one wants another brain surgery, but with a shunt you'll notice improvement in the areas that you mention rather quickly. The shunt itself is not noticeable to the general public, no one would know unless you tell them.
Your Doctor will be able to explain things better, but please know that it isn't as big of a procedure as what you have all ready had. The shunt not only saved my husband's life, by controlling the hydro problems it added to his quality of life. The headaches, (guessing back of the head and behind the eyes, pretty intense) nausea, memory and balance improved.
Please please keep us updated, and feel free to contact me directly.
Best to you
