relatively spared fourth ventricle. His ventricles did not substantially shrink after a technically successful ETV. We speculate that his symptoms were analogous to idiopathic normal pressure hydrocephalus (iNPH) and related to chronic ventriculomegaly as opposed to elevated ICP. While surgeons have attempted ETV for elderly patients with iNPH, 14 the published results have not convincingly demonstrated efficacy. 24 , 29 The clinical triad of findings of iNPH (dementia, gait disturbance, and incontinence) are well known, but the pathophysiology is not understood.

striatum and substantia nigra. 19 , 37 Following ventricle enlargement, acute hydrocephalic rats showed decreased exploration into the open arms of an elevated plus maze. Additionally, hydrocephalic rats made decreased entries and spent less time in the open arms. These results suggest that acute hydrocephalus increases anxiety response. In a study involving patients with idiopathic normal pressure hydrocephalus, anxiety symptoms were examined and evaluated with neuropsychiatric scoring. 22 A quarter of the patients with idiopathic normal pressure hydrocephalus were

-time demonstration should be a significant improvement in intraoperative monitoring of shunt placement and any resultant bleeding. Opening pressures of the ventricles were recorded only in the 22 cases of right ventriculosubgaleal shunting by a subarachnoid intracranial pressure monitor bolted into the left frontal skull. 3 The Discussion section of my article compares the incidence of delayed intracerebral hemorrhage caused by ventriculoperitoneal shunt insertion in the pediatric population with the few previously reported cases. Table 1 lists 58 instances of idiopathic normal-pressure

classification of the patterns of hydrocephalus across those etiologies are demonstrated in Table 1 and in Fig. 2 . Classes of adult hydrocephalus were defined as follows: 1) acquired, 2) transitional (treatment initiated during childhood years), 3) longstanding overt ventriculomegaly in adults (LOVA) or adults with previously untreated congenital hydrocephalus (APUCH) (often also referred to as chronic congenital hydrocephalus, arrested hydrocephalus, or compensated hydrocephalus), and 4) idiopathic normal pressure hydrocephalus (iNPH). 12 , 24 Patients with congenital

T he pathophysiology of IAHS, 31 or idiopathic normal-pressure hydrocephalus, 1 is still an enigma. Today two principally different mechanisms are considered: 1) an altered hydrodynamics of the CSF system; and 2) a parenchymal, possibly ischemic, process. The former is demonstrated by modestly raised ICP, increased CSF R out , 31 and the presence of abnormal B-wave patterns; 13 the latter is indicated by cortical and subcortical decreased blood flow 27 and metabolism 2, 42 as well as periventricular white matter lesions. 26 In addition, increased blood
