The Brain Structure and Neural Network Changing the Before and After Ventriculo-peritoneal Shunting in the Normal Pressure Hydrocephalus Patients
Study Details
Study Description
Brief Summary
With the advent of the aging society, dementia becomes the focus of common people. As for the neurodegeneration dementia, no disease modifying treatments have been discovered. Idiopathic normal pressure hydrocephalus (iNPH) is considered as one of reversible dementia, which can be hint by the surgery. In addition, dementia of iNPH is the typical subcortical dementia. Therefore exploring the pathogenic mechanism is conducive to the early diagnosis and treatment. This research is to monitor the changing of iNPHGS, cognitive function, walking ability as well as brain construction imaging and neural network before and after ventriculo-peritoneal shunting in order to demonstrate the pathogenesis of triads. In the process, the supplementary test, for instance, CSF tap test, will be validated the predictive value.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| normal pressure hydrocephalus Included will be subjects with a probable diagnosis of NPH. The diagnosis will be based primarily on presence of gait impairment plus at least one other impairment in urinary symptoms, cognition impairment or both The NPH patients will undergo the CSF tap test and then receive the ventriculo-peritoneal shunting surgery. They will have the examination of brain constructure neuroimaging and functional MRI prior to and posterior to the shunting. |
Procedure: ventriculo-peritoneal shunting
A mainstream therapy for NPH. It involves the device of CSF flow control of shunts and accessories(CFDA(I)20143665605)
|
| normal control Healthy volunteers will undergo the examination of brain constructure and functional MRI. |
