Venous hemodynamics in neurological disorders: an analytical review with hydrodynamic analysis. [PDF]

, 2013
Venous abnormalities contribute to the pathophysiology of several neurological conditions. This paper reviews the literature regarding venous abnormalities in multiple sclerosis (MS), leukoaraiosis, and normal-pressure hydrocephalus (NPH).

Differential Progression of Neuroinflammation in Patients with Isolated Rapid‐Eye‐Movement Sleep Behavior Disorder

Movement Disorders, EarlyView.
Abstract Background Neuroinflammation, measured using [11C](R)‐PK11195 positron emission tomography (PET), has been reported in isolated rapid‐eye‐movement sleep behavior disorder (iRBD), but its temporal progression is unknown. Objective The aim was to assess longitudinal progression of neuroinflammation in iRBD patients and its relationship with ...

Imaging and physiology across the high–low cerebrospinal fluid pressure spectrum: Navigating diagnostic uncertainty in headache practice

Headache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study was conducted to provide a clinically oriented, mechanism‐based framework for interpreting neuroimaging across disorders of cerebrospinal fluid (CSF) pressure, with particular emphasis on patients who fall between classic diagnostic categories of spontaneous intracranial hypotension (SIH) and idiopathic intracranial ...

Increased CSF aquaporin-4, and interleukin-6 levels in dogs with idiopathic communicating internal hydrocephalus and a decrease after ventriculo-peritoneal shunting [PDF]

, 2016
Background: Studies in animal models, in which internal hydrocephalus has been induced by obstructing the cerebrospinal fluid pathways, have documented an up-regulation of the concentrations of aquaporin-4 (AQP4) in the brain.

Exploring Theory of Mind abilities in patients with probable idiopathic normal pressure hydrocephalus

Journal of Neuropsychology, EarlyView.
Abstract This study investigated Theory of Mind (ToM) deficits in patients with suspected idiopathic normal pressure hydrocephalus (iNPH), a condition affecting motor, cognitive and autonomic functions. Given the overlap between ToM‐related neural networks and those affected in iNPH, we examined whether ToM impairments are a feature of the disease ...

Decrease of excessive daytime sleepiness after shunt treatment for normal pressure hydrocephalus

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleepiness and apathy are often reported in patients with normal pressure hydrocephalus. However, research on outcomes after shunt surgery has mainly focused on the classical triad symptoms, that is, gait, cognition, and bladder dysfunction. This study aimed to describe the effects of shunt treatment on excessive daytime sleepiness and whether ...

Are brain displacements and pressures within the parenchyma induced by surface pressure differences? A computational modelling study.

PLoS ONE, 2023
The intracranial pressure is implicated in many homeostatic processes in the brain and is a fundamental parameter in several diseases such as e.g. idiopathic normal pressure hydrocephalus.

Overnight Dynamics of Ventricular Cerebrospinal Fluid Amyloid‐Beta, Lactate and Hypocretin in Patients With Hydrocephalus: A Pilot Study

Journal of Sleep Research, EarlyView.
ABSTRACT This pilot observational study evaluated whether frequent overnight sampling of ventricular cerebrospinal fluid could clarify how sleep, hypocretin and lactate relate to amyloid‐β42 dynamics in adults with hydrocephalus. Seven participants underwent hourly ventricular cerebrospinal fluid sampling from early evening to late morning during ...
