TLDR
This hypothesis also accounts for hydrocephalus resulting from obliteration of the cortical subarachnoid space, obstruction to the cranial venous drainage, deformities in the region of the foramen magnum and arterial encroachment upon the ventricular system.About:

Radiological assessment of hydrocephalus: new theories and implications for therapy
TL;DR: The new hydrodynamic theories explain why third ventriculostomy may cure patients with communicating hydrocephalus, a treatment incompatible with the conventional view.
Journal ArticleDOI
Pulsatile brain movement and associated hydrodynamics studied by magnetic resonance phase imaging: The Monro-Kellie doctrine revisited
TL;DR: Brain tissue movements were studied in axial, sagittal and coronal planes in 15 healthy volunteers, using a gated spin echo MRI sequence, and the resultant movement occurred in a funnelshaped fashion as if the brain were pulled by the spinal cord.
Journal ArticleDOI
Recent research into the nature of cerebrospinal fluid formation and absorption
TL;DR: Recent information regarding the nature of bulk cerebrospinal fluid formation and absorption is reviewed, integrated with previous knowledge, and applied to the clinical setting.
Journal ArticleDOI
A model of pulsations in communicating hydrocephalus.
TL;DR: A model of intracranial pulsations based on the analogy between the pulsatile motion of electrons in an electrical circuit and the pulses of blood and CSF in the cranium is developed and it is proposed that communicating hydrocephalus is the result of a redistribution of CSF pulsations in thecranium.
Journal Article
Vascular Compliance in Normal Pressure Hydrocephalus
TL;DR: Vascular compliance is significantly different in the brains of healthy subjects as compared with that in patients with ischemia/atrophy or NPH.

The special clinical problem of symptomatic hydrocephalus with normal cerebrospinal fluid pressure: Observations on cerebrospinal fluid hydrodynamics
S. Hakim,R.D. Adams +1 more
TL;DR: A state of symptomatic hydrocephalus may exist in the presence of normal CSF pressure in patients who had exhibited mental dullness, inattentiveness, psychomotor retardation, unsteadiness of gait, and incontinence of urine, a syndrome which may be mistakenly ascribed to a degenerative or traumatic vascular disease of the cerebrum.
