Outcomes
Primary Outcomes
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.
