简要总结
Normal pressure hydrocephalus (NPH) can cause a type of dementia. However, this type of dementia is the only one that is reversible. To treat this dementia it is necessary to evacuate the accumulation of CSF from the brain to another body cavity using a device called a shunt. But the implantation of this shunt is only effective when the cause of the pathology is an alteration of the normal circulation of the CSF. To diagnose these patients, morphological MRI and lumbar puncture are standard approaches used but remain perfectible in diagnostic terms.
The main objective is to build a new model of the interaction of intracranial pressures and fluids in order to obtain a new parameter allowing to obtain information on the cerebral biomechanics.

结局指标
主要结局
Variation of number of MRICP parameters according of CSF accumulation
时间窗: up to 3 years
The MRICP parameter will combine the CSF pressure and CSF flows. MRICP parameter results of the interaction of intracranial pressures and fluids in order allowing to obtain information on the cerebral biomechanics. Accumulation of CSF from the brain to another body cavity is neccessary to be determined.
