Arterial spin-labeling perfusion MR imaging demonstrates regional cbf decrease in idiopathic normal pressure hydrocephalus

, 2017
BACKGROUND AND PURPOSE: Regional cerebral blood flow has previously been studied in patients with idiopathic normal pressure hydrocephalus with imaging methods that require an intravenous contrast agent or expose the patient to ionizing radiation.

Rapid Tissue‐CSF Water Exchange in the Human Brain Revealed by Magnetization Transfer Indirect Spin Labeling

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3270-3283, June 2026.
ABSTRACT Purpose To apply the Magnetization Transfer Indirect Spin Labeling (MISL) MRI technique for quantifying tissue‐CSF water exchange in the human brain, and to investigate its utility in (1) evaluating tissue‐CSF water exchange within perivascular spaces (PVS), and (2) characterizing altered water exchange dynamics in pathologic conditions ...

Deciphering Freezing of Gait: What Neuropathology Reveals About an Episodic Phenomenon

European Journal of Neuroscience, Volume 63, Issue 12, June 2026.
Freezing of gait (FoG) occurs across Parkinson's disease, multiple neurodegenerative conditions and non‐neurodegenerative disorders. This review synthesizes the structural, neurochemical and proteinopathic substrates underlying FoG, showing how cumulative damage to distributed locomotor circuits—compounded by overlapping pathologies—progressively ...

Natural course and long-term prognosis in idiopathic Normal Pressure Hydrocephalus - the effect of delayed surgery and clinical factors on outcome and survival [PDF]

, 2020
Idiopathic Normal Pressure Hydrocephalus, iNPH, causes gait and balance difficulties, urinary incontinence and cognitive decline in mainly older persons and is treatable by insertion of a cerebrospinal fluid diverting shunt.

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, Volume 66, Issue 6, Page 1405-1418, June 2026.
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 ...
