Cerebrospinal fluid biomarkers in idiopathic normal pressure hydrocephalus

Неврология, нейропсихиатрия, психосоматика, 2019
The diagnosis of idiopathic normal pressure hydrocephalus (iNPH) presents difficulties because of the same symptomatology in neurodegenerative diseases. The data of brain magnetic resonance imaging (MRI) and invasive techniques (tap test, external lumbar

Fluid-solid coupling model and biological features of large vestibular aqueduct syndrome

Frontiers in Bioengineering and Biotechnology, 2023
Objective: Computed tomography (CT) images of the temporal bone of large vestibular aqueduct syndrome (LVAS) patients were used to establish 3D numerical models based on the structure of the inner ear, which are, in turn, used to construct inner ear ...

Cerebral microcirculation mapped by echo particle tracking velocimetry quantifies the intracranial pressure and detects ischemia

Nature Communications, 2022
Hydrocephalus involves abnormal accumulation of cerebrospinal fluid, resulting in elevated intracranial pressure. The authors developed contrast-enhanced ultrasound imaging and intravascular microbubbles tracking in hydrocephalic pediatric porcine models

Spatial and Volumetric Characteristics of Glioblastoma: Associations With Clinical Presentation and Survival

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.

A novel rat model to study the role of intracranial pressure modulation on optic neuropathies. [PDF]

PLoS ONE, 2013
Reduced intracranial pressure is considered a risk factor for glaucomatous optic neuropathies. All current data supporting intracranial pressure as a glaucoma risk factor comes from retrospective and prospective studies.

EFFECTS OF ALTHESIN ON CEREBROSPINAL FLUID PRESSURE

British Journal of Anaesthesia, 1973
SUMMARY Changes in cerebrospinal fluid pressure after induction of anaesthesia with Althesin were recorded in 21 volunteer patients who had no abnormality of the central nervous or cardiorespiratory systems. In patients who breathed spontaneously, cerebrospinal fluid pressure fell by 45% at 1 min after intravenous injection of Althesin 0.1 ml/kg.

Peptide fingerprinting of Alzheimer's disease in cerebrospinal fluid: identification and prospective evaluation of new synaptic biomarkers [PDF]

, 2011
<p><b>Background:</b> Today, dementias are diagnosed late in the course of disease. Future treatments have to start earlier in the disease process to avoid disability requiring new diagnostic tools.

Subclinical Optic Nerve Involvement in Radiologically Isolated Syndrome: Multimodal Detection and Diagnostic Impact

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We aimed to determine the frequency of subclinical optic nerve (ON) lesions using MRI, optical coherence tomography (OCT), and visual evoked potentials (VEP) in radiologically isolated syndrome (RIS), and to assess their diagnostic and prognostic significance.

Blood pressure lowering enhances cerebrospinal fluid efflux to the systemic circulation primarily via the lymphatic vasculature

Fluids and Barriers of the CNS
Background Inside the incompressible cranium, the volume of cerebrospinal fluid is directly linked to blood volume: a change in either will induce a compensatory change in the other.

Hakim-Adams syndrome: An unusual cause of reversible postoperative coma.

Frontiers in Medicine, 2016
We report the case of a 72 years old patient presenting in our ICU with persistent postoperative coma in a context of recent unexplored neurological dysfunction. Detailed medical history taking from the patient’s family revealed he recently suffered from
