Brief Summary
The purpose of the study is to determine the predictive values and prognostic accuracies of CSF dynamic measures, the TAP -TEST (high-volume cerebrospinal fluid withdrawal), resistance to CSF outflow and compliance in the prediction of shunt-treatment outcome in patients with idiopathic normal pressure hydrocephalus.

Interventions

Eligibility Criteria
You may qualify if:
- Clinical diagnosis (neurological and radiological criteria) of idiopathic normal pressure hydrocephalus
- Typical INPH
- Clinical criteria:
- Gradually developed gait disturbance of both legs, unexplained by other conditions. Disturbance of tandem walking, multi-step turning, small steps and wide base must be present at least.
- MMSE score 21-30 without aphasia, apraxia and agnosia
- Bladder instability and postural instability may be present.
- Radiological criteria (MRI):
- Symmetrical communicating quadri-ventricular enlargement without cortical infarcts or other clinically relevant parenchymal lesions but lacunar infarcts of less than 1 cc may be present
- Evans index \> 0.30 and temporal horns and third ventricle relatively enlarged.
- Mild cortical atrophy and mild leuco-araiosis may be present.
- Questionable NPH
- Clinical criteria:
- Any gait disturbance of both legs that does not fulfill the criteria of typical INPH, but is compatible with INPH.
- MMSE score \< 21
- Bladder instability and postural instability may be present.
- +4 more criteria
You may not qualify if:
- Secondary Normal pressure Hydrocephalus
- Non-communicating hydrocephalus
- Secondary NPH (after SAH, trauma, infection, neurosurgical procedure). Trauma or infection are regarded as relevant if the patient was unconscious in relation to the trauma or required hospitalisation for his meningo-encephalitis.
- INPH-patients later shown to have ICP \> 18 mm Hg.
- Contra-indications to surgery.
- Patients refusing shunt surgery
- Restricted life-expectancy
- Patients not capable of managing the tests or investigations at entry of the study
