BACKGROUND AND PURPOSE Although neuroimaging plays an important role in the diagnosis of idiopathic normal pressure hydrocephalus, its predictive value for response to shunt surgery has not been established. The purpose of the current study was to identify neuroimaging markers that predict the shunt response of idiopathic normal pressure hydrocephalus. MATERIALS AND METHODS Sixty patients wit...

The log-normal distribution is one of the most common distributions used for modeling skewed and positive data. In recent years, various methods for comparing the means of two independent log-normal distributions have been developed. In this paper a higher-order likelihoodbased method is proposed. The method is applied to two real-life examples and simulation studies are used compare the accura...

A 76-year-old woman presented with a dural arteriovenous fistula (DAVF) manifesting as typical symptoms of normal pressure hydrocephalus such as progressive dementia, gait disturbances, and urinary incontinence. The cerebrospinal fluid pressure during lumbar puncture was 120 mmH(2)O. Computed tomography and magnetic resonance imaging showed ventricular dilation and diffuse white matter changes,...

Case Report: Optical Coherence Tomography, as a Non-Invasive Approach to Evaluate Intracranial Pressure in Normal Hydrocephalus Patients, with their Treatment Follow-ups and VP Shunts Reprogramming Procedures

CSF normally flows back and forth through the aqueduct during the cardiac cycle. During systole, the brain and intracranial vasculature expand and compress the lateral and third ventricles, forcing CSF craniocaudad. During diastole, they contract and flow through the aqueduct reverses. Hyperdynamic CSF flow through the aqueduct is seen when there is ventricular enlargement without cerebral atro...

Introduction: Arrested hydrocephalus is a state of chronic hydrocephalus with mild dilatation of the ventricles in which the cerebrospinal fluid pressure has returned to normal, and there is no pressure gradient between the cerebral ventricles and brain parenchyma. Case Report: In this case report, we present a 37-year-old female patient who was admitted to emergency department with complaints ...
