The pathophysiology of acute mountain sickness and high-altitude cerebral edema, the
cerebral forms of high-altitude illness, remain uncertain and controversial. Persistently …

Objectives How changes in intracranial compliance (ICC), resistance to cerebrospinal fluid
(CSF)-outflow (R out), and pressure-volume index (PVI) can play a prominent role in …

Background Infusion testing is a common procedure to determine whether shunting will be
beneficial in patients with normal pressure hydrocephalus. The method has a well …

Background It is suggested that disturbed CSF dynamics are involved in the
pathophysiology of idiopathic normal pressure hydrocephalus (INPH). The pulsatility curve …

Excessive intracranial pulsatility is thought to damage the cerebral microcirculation, causing
cognitive decline in elderly individuals. We investigated relationships between brain …

OBJECTIVE A better understanding of the effect of position on intracranial pressure (ICP)
and compliance is important for the development of treatment strategies that can restore …

Purpose.: As efforts to noninvasively measure intracranial pressure (ICP) increase, we
thought it important to investigate the timing of retinal venous pulsation in relation to the …

Cerebrospinal fluid (CSF) flows through the perivascular spaces (PVSs) surrounding
cerebral arteries. Revealing the mechanisms driving that flow could bring improved …

Background The association between intracranial pressure (ICP) and different shunt valve
opening pressures in relation to body positions is fundamental for understanding the …

Astronauts aboard the International Space Station (ISS) have exhibited hyperopic shifts,
posterior eye globe flattening, dilated optic nerve sheaths, and even optic disk swelling from …
