First paragraph (this article has no abstract)

It has been postulated that NPH equals pressure- and distortion-induced ischemia. Such a postulate fails to take into consideration the high co-incidence of AD and cerebrovascular disease (CVD) with NPH; as well as the observation that ischemia persists despite resolution of the elevated CSFP and ventriculomegaly [1,2]. We offer an alternate postulate, that NPH is a multi-factorial disease and that defective metabolite clearance, e.g., amyloid-beta peptides (Aβ) and Tau protein, via the CSF and across the blood-brain barrier (BBB), play a significant role in the dementia and ischemia of NPH.
