Outcome Measures

Primary Outcomes (2)

  • Proteomic pattern of CSF in iNPH patients

    Comparing the proteomic pattern differences in CSF between iNPH patients and normal age-matched normal volunteers by the analysis of mass spectrometry. Also, the responsive and non-responsive iNPH patients proteomic pattern were analzed.

    Before surgery in lumbar CSF

  • Proteomic pattern changes of CSF in iNPH patients after VP shunt

    Comparing the proteomic pattern differences in CSF of iNPH patients before surgery and after VP shunt by the analysis of mass spectrometry. Also, the responsive and non-responsive iNPH patients proteomic pattern were analzed.

    Change from Baseline (ventricular CSF) at 6 months after VP shunt

Secondary Outcomes (7)

  • Gray Matter Density

    Before surgery

  • Change in the resting state fMRI

    Before surgery

  • White matter abnormity

    Beore surgery

  • Kiefer score

    Change from Baseline at 6 months after VP shunt

  • Mini mental state Examination

    Change from Baseline at 6 months after VP shunt

  • +2 more secondary outcomes

Study Arms (1)

iNPH cohort

EXPERIMENTAL

The patients diagnosed of iNPH.

Procedure: ventriculo-peritoneal shunt

Interventions

A ventriculoperitoneal shunt is a tube that drains excess cerebrospinal fluid into abdomen

iNPH cohort
