Filter by:The eShunt® System is a minimally invasive method of treating communicating hydrocephalus. The eShunt System includes a proprietary eShunt Delivery System and the eShunt Implant, a permanent implant deployed in a minimally invasive, neuro-interventional procedure. The eShunt System is intended to shunt cerebrospinal fluid from the intracranial subarachnoid space to the venous system for the treatment of patients with normal pressure hydrocephalus, reducing disability due to symptoms including one or more of gait disturbance, cognitive dysfunction and urinary incontinence.
Idiopathic normal pressure hydrocephalus (INPH) is a treatable disease of the elderly, typically causing gait impariment, dementia and urinary incontinence. The objective of this study is to make an epidemiological survey of INPH in Umeå, Sweden. Subjects with self-perceived gait impairments will be identified through a questionnaire. They will go through clinical examinations and have an MRI of the brain. A control population will also be investigated to enable comparisons between the populations. The main hypothesis is that the prevalence of INPH in the population is higher than what is previoulsy known.
The Placebo-Controlled Efficacy in Idiopathic Normal Pressure Hydrocephalus (iNPH) Shunting (PENS) trial is a multi-center blinded, randomized, placebo-controlled design investigation of cerebrospinal fluid (CSF) shunt surgery to study the shunt efficacy in iNPH patients.
The research is designed to study the prognostic factors of ventriculoperitoneal (VP) shunt for iNPH by multi-omics research
A pharmacological treatment to patients with normal pressure hydrocephalus (NPH) is missing. The aim is to investigate if acetazolamide given to patients with NPH improves gait function and study the pathophysiological mechanisms leading to reduced symptoms. Patients will be randomized to acetazolamide or placebo and duration of treatment will be from diagnosis to the day of shunt surgery. Target dose is 500 mg/day. Study design is a double-blind randomized controlled trial and the plan is to include 42-50 patients. The study is investigator-initiated without financial sponsorship from the industry.
LiNPH is a prospective single center clinical and radiological study.
Part 1 Patients with idiopathic Normal Pressure Hydrocephalus (iNPH) have variable disabilities regarding gait, balance, cognition and continence. Analysis of the gait pattern in iNPH has an important part in clinical diagnosing and evaluation of outcome after shunt surgery. The gait pattern is only partly explained and more detailed information about gait in iNPH is needed in relation with ordinary clinical measurements. Part 2 Approximately 70 % of patients with iNPH improve after shunt surgery. Commonly different grading scales and measurements regarding functions are used in the evaluation. To some extent, patients improve in Quality of life after surgery (QoL). In this study, the patient´s own grading of improvements in relation with QoL, sense of coherence (SOC) and symptoms of depression and anxiety are analyzed.
Idiopathic normal pressure hydrocephalus (=iNPH) is a condition with disturbed circulation of cerebrospinal fluid (=CSF) causing symptoms such as balance and gait disorders, urinary incontinence and cognitive impairment in patients with cerebral ventricular dilation. The exact incidence is unknown but has been estimated at about 8.9% of the population over the age of 80 and the incidence is estimated to increase with an aging population. The symptoms can be temporarily improved by draining cerebrospinal fluid and so-called shunting (surgery with diversion of cerebrospinal fluid from the brain to the abdominal cavity). The symptoms and pathophysiology of iNPH are poorly described as well as the protein distribution in cerebrospinal fluid (proteomics) of the disease. There is also a need for improved diagnostical and prognostical tools that can guide in patient selection for surgery. The radiological tools in evaluating the disease and it´s progression need to be improved. There is a shunt valve (Codman Certas Plus) used since 2015 that is widely used in clinical use and is well studied in research laboratories but little in clinical studies. The project aims to, before and after surgery, on patients with iNPH who will undergo investigation and shunting with Certas Plus at our department and in comparison with healthy controls: 1. Apply and evaluate a novel method to determine the volume of circulating CSF (volumetry). 2. Study the correlation between changes in volumetry and clinical outcome 3. Study NPH patients' distribution of proteins in cerebrospinal fluid and their change over time after shunting. 4. Evaluate the efficacy and functions of the Certas Plus valve. In this way, the investigators hope to find increased knowledge about the NPH disease and its pathophysiology as well as useful instruments that can both predict the probability for a patient to be improved by a shunt operation and determine if a shunt has stopped working and thus be able to avoid unnecessary risky operations.
20 patients who are diagnosed with NPH receive a set of 5 wearable gyroscopes (IMUs, ZurichMove sensors) for a period of 3 days for measurement and characterization of their walking in an ambulatory setting. At a follow-up 2 weeks to 6 months after CSF diversion surgery, the examination is repeated and improvement is measured. The data will be compared with a healthy group of 20 age- and gender-matched individuals as well a a group of 20 young individuals.
This randomized, double-blinded, cross-over study aim to evaluate the effects of shunt treatment in idiopathic normal pressure hydrocephalus (iNPH) by measuring cerebral ventricular volume and clinical symptoms at different shunt opening pressures. Further, proteins in the cerebrospinal fluid (CSF) will be compared before and after shunt surgery.
