Filter by:Infusion tests are now the gold standard for the diagnosis of chronic adult hydrocephalus (CAH), also known as normal pressure hydrocephalus. It is an invasive procedure using the same approach as a lumbar puncture. Once the intrathecal puncture is performed, the intracranial pressure is measured in lateral decubitus via a pressure head. Dynamic tests (injection of 0.9% NaCl at a constant flow rate) are performed after recording the basal pressure. This type of test lasts 30 to 45 minutes in lateral decubitus. Patients with CAH have cognitive-behavioral disorders that can alter the gesture and its interpretation in case of movements or contractures. Movement artefacts lead to a longer recording time. The longer the test, the more the patients' tolerance tends to decrease. Moreover, the patient's feeling towards this test is important because it may have to be repeated. Pain, anxiety and patient comfort are essential parameters to consider. Non-medicinal techniques (hypnosis, music therapy) have shown a tendency to reduce anxiety in pediatric and adult populations with an impact on instantaneous anxiety but also on personality-related anxiety. Most studies are focused on specific pathologies, primarily in palliative care, or on pediatric application. The use of these techniques in an elderly population with mild cognitive-behavioral disorders has not been explored. The objective is to evaluate the impact of hypnosis on anxiety, pain and comfort during the lumbar infusion test.
This study aims to evaluate the effect of tele-education given to parents of children with ventriculoperitoneal shunt on their anxiety and self-efficacy.
This study evaluates the performance of a device for non-invasively assessing cerebrospinal fluid (CSF) shunt flow. Patients with an existing implanted shunt will wear the device to acquire longitudinal data.
Normal pressure hydrocephalus (NPH) is a neurodegenerative disease of unclear etiology characterized by a clinical trias named after the neurosurgeon Hakim. It includes cognitive impairment (dementia), gait disturbance, and urinary incontinence. These symptoms, which frequently occur in the elderly population, often overlap with the symptoms of "other" neurodegenerative diseases, especially Alzheimer's disease and other (pre)senile dementias. To distinguishing NPH from "other" dementias is crucial in determining whether a patient will benefit from a surgical procedure (ventriculoperitoneal shunt placement) or not. At the same time, the options for assessing the patient's condition's progression and distinguishing between the progression of neurodegeneration in a broader sense or malfunction of the drainage system are very limited. Therefore, the role of a biomarker that could meet these expectations mentioned above is highly desirable.
Measurements of shunt flow will be performed non-invasively. This study will generate usability data via observed tasks and comprehension questions to enable future device design improvements.
In all published series of adult chronic hydrocephalus, there is a percentage between twenty and twenty-five percent of patients who present poor results after implantation of a cerebrospinal fluid shunt,1-11 usually ventriculoperitoneal. The lumboperitoneal shunt is also used but much more rarely. The diagnosis of this pathology is based on the clinical picture, neuroimaging studies (Evans index and corpus callosum angle), cerebrospinal fluid dynamics tests (Katzman test), and invasive intracranial pressure measurements. Despite all this diagnostic arsenal, there is a high percentage of patients (mentioned above) in which treatment by diversion of cerebrospinal fluid does not offer the expected results. Traditionally this has been attributed to chronic adult hydrocephalus being associated with other types of dementia. This may be the case in some patients, and it would be important to be able to predict which patients will not improve or who will improve poorly in the case of implantation of a cerebrospinal fluid shunt.
To investigate if progression from prodromal into symptomatic NPH can be predicted from advanced neuroimaging, biomarkers in cerebrospinal fluid (CSF) and plasma and investigate the unknown mechanisms causing deterioration by investigating longitudinal changes in the above-mentioned variables. Three different cohorts with both asymptomatic and symptomatic patients as well as healthy controls will be investigated over time, both without intervention and before and after shunt surgery.
Hydrocephalus is characterized by excessive accumulation of cerebrospinal fluid (CSF) in the ventricles of the brain. One of the forms of hydrocephalus is called "normal pressure", although one of the main signs is precisely an alteration of the intracranial pressure (ICP), it is here called active hydrocephalus (HA). Although MRI is the reference radiological modality for the characterization of HA. The Evan's and DESH index are radiological diagnostic criteria based on the dilation and morphology of the CSF compartments. These morphological indices remain insensitive and specific. In recent years, advances in Phase Contrast (MRI-PC) and Diffusion (MRI-DTI) MRI have generated new biomarkers of brain viability. The aim of this study is to characterize by MRI the impact of hydrocephalus on brain fluids and tissues.
Patient with childhood hydrocephalus (HC) tend to present late in Low medium income countries (LMICs). This project will study the barriers leading to patients' and health system delay in patients with childhood HC. This will be done via a quantitative and qualitative study analysis. The data will be collected prospectively.
The goal of this study is to investigate effect of exercise program on balance, gait and performance in patients with normal pressure hydrocephalus applied with lumbar puncture. The main question it aims to answer are: - Home based exercise program effective on balance, gait and performance - Telerehabilitation exercise program effective on balance, gait and performance Researchers will compare home based exercise group, telerehabilitation group and control group to see if difference in terms of balance, gait and performance
