Umeå University Identifier:
First received: December 21, 2010
Last updated: December 22, 2010
Last verified: December 2010
A computerised neuropsychological test battery to be used as a standardised tool assessing the cognitive domains affected by idiopathic normal pressure hydrocephalus INPH was developed. The aim of this study is to investigate the reliability, validity and feasibility of the battery.

Condition Intervention
Normal Pressure Hydrocephalus Device: Computerized neuropsychological test Other: Conventional neuropsychological test

Study Type: Observational
Study Design: Time Perspective: Cross-Sectional
Official Title: Evaluation of a Computerised Neuropsychological Test Battery for Idiopathic Normal Pressure Hydrocephalus (INPH)

Primary Outcome Measures:
  • Validity [ Time Frame: Within 24 h ]
    Computerized test battery and equivalent standard neuropsychological test battery is given to the same subject. Correlation between paper and pen and equivalent computerized test is calculated as a validity measure.

  • Reliability [ Time Frame: More than 7 days, within 2 months ]
    The computerized test battery is given to the same subject twice. Correlation between the two tests is calculated as a test-retest reliability measure.

  • Feasibility [ Time Frame: Within 24 h ]
    Patients under the investigation for INPH are given the computerized test battery. Number of patients who manage to complete the test is the feasibility measure.
