Although ventricular shunting of NPH is effective in halting progression and reversing deficits in some patients, treatment failures abound. Treatment failures are in part attributable to faulty selection of patients and/or suboptimal shunting techniques. In this issue of the ARCHIVES, Bergsneider et al³ help to refocus attention on some of the important issues in treatment of adult patients with NPH.

Normal pressure hydrocephalus was recently the subject of fine reviews by Vanneste et al,^4-5 so only the briefest overview is needed here. It may be communicating or noncommunicating. The noncommunicating type of NPH is most commonly caused by aqueductal stenosis. Approximately 50% . . . [Full Text of this Article]
