An investigation of CSF dynamics and biochemical composition in normal pressure hydrocephalus utilizing the phase contrast MRI scanning
… shunt to drain excess cerebrospinal fluid (CSF) from the ventricles of the brain. In addition, it is associated with difficulty in walking (which usually precedes dementia) and incontinence (which usually follows dementia). It is important to diagnose this condition properly as there are …

Processing random signals in neuroscience, electrical engineering and operations research
… based model of cerebrospinal fluid (CSF) dynamics, whose structure is fundamentally determined by an electrical circuit analogy. Our general Langevin framework encompasses many of the existing equations used in electrical engineering, neuroscience, biomedical engineering and …

Novel model of cerebrospinal fluid dynamics based on hemodynamically driven cyclic brain compliance variation
… novel explanation for the CerebrQ-Spinal Fluid (CSF) flow pattern observed in phase contrast cine-MRJ studies. CSF dynamics has been traditionally explained as a bulk flow from the site of production to the site of absorption. Studies done with phase contrast cine-MRI show a more complex CSF …

Dynamics of cerebral fluids in patients suffering from hydrocephalus and pseudotumour cerebri
This dissertation is devoted to dynamics of brain liquids in patients with altered CSF circulation and pressure-volume compensation. Since the introduction of intracranial pressure (ICP) monitoring, the studies of CSF dynamics have revealed unique information about the intracranial circulation and …

The formation and function of the brain ventricular system
… of cavities that contain cerebrospinal fluid (CSF), a protein-rich fluid essential for brain function. However, little is known about the function of embryonic CSF (eCSF), or the mechanisms of CSF production, retention, and circulation that regulate brain ventricle shape and size. Here we …

The Clinical Analysis of Factors Predicting the Need for Shunting in Normal Pressure Hydrocephalus
… patients with NPH were shown to be treated by a CSF shunt operation.However,it is well known not all patients presenting the syndrome benefit from a shunt operation.In order to proper patients selection for shunt operation, various radiological and CSF dynamic investigations was essential to …

Mathematical Modelling of Brain Haemodynamics and Pressure-Volume Compensation
… the performance of indices describing vascular dynamics were also examined. The background of this project is discussed in Chapters 1 to 4 of this thesis. Chapter 1 provides a description of the anatomical and physiological aspects of the cerebrospinal space, including the circulation of …

Computational modelling of global haemodynamics and its interaction with cerebrospinal fluid and brain dynamics with application to essential hypertension
… refined description of the cerebrospinal fluid (CSF) dynamics in the craniospinal cavity. Two versions of the CSF model are presented; both versions account for deforma-tions and interaction between the cerebral vasculature, brain parenchyma and CSF compartments during the cardiac cycle. The …
