Summary:

"Presents information on pathophysiology, diagnosis, and treatment of idiopathic normal pressure hydrocephalus. Highlights the importance of determining the benefits of surgical implantation of a VP shunt. Because NPH is often incorrectly diagnosed with disorders such as Parkinson disease, the challenges faced in accurate diagnosis of NPH are discussed. Describes clinical signs and symptoms, radiographic findings, and diagnostic testing"--Provided by publisher.
