BACKGROUND AND PURPOSE: Chronic hydrocephalus is associated with dilated
ventricles despite a normal intracranial pressure. In idiopathic intracranial hypertension, the …

Object Both idiopathic intracranial hypertension (IIH) in adults and idiopathic hydrocephalus
in children have been shown to involve elevations in venous pressure that resolve once the …

ABSTRACT BACKGROUND The pathogenesis and diagnostic methods for idiopathic
normal pressure hydrocephalus (iNPH) have been active areas of research in recent years …

BACKGROUND AND PURPOSE: Many theories of normal pressure hydrocephalus (NPH)
stress the importance of ischemia in the deep white matter. Alternate theories stress a …

Object In the majority of adults with idiopathic intracranial hypertension (IIH), there is an
elevation in venous pressure associated with a venous outflow stenosis. In about 15% of IIH …

Normal pressure hydrocephalus (NPH) is a surgically treatable reversible neurological
disorder initially identified in 1957 by a Colombian neurosurgeon, Solomon Hakim [1]. At …

BACKGROUND AND PURPOSE: Aqueductal stroke volume from phase-contrast MR
imaging has been proposed for predicting shunt response in normal pressure …

BACKGROUND AND PURPOSE: Normal pressure hydrocephalus (NPH) is considered to
be a combination of altered CSF resorption and a reversible form of cerebral ischemia. The …

Superficial cortical venous compression secondary to alterations in craniospinal compliance
is implicated in the pathogenesis of normal pressure hydrocephalus (NPH). A reduction in …

Objectives To evaluate complex CSF movements and shear stress in patients with idiopathic
normal pressure hydrocephalus (iNPH) on four-dimensional (4D) flow MRI. Methods Three …
