iPAD-BASED ASSESSMENT IN PARKINSON'S DISEASE

BackgroundIn order to facilitate neuroprotective trials in Parkinson's disease (PD), there is a need for improved means of early disease detection and measuring disease progression. Computerised assessment may afford easier and increasingly accurate administration of motor and cognitive tests, as well as measurement of indices not readily accessible with standard testing paradigms.AimTo develop and validate iPad-based cognitive and motor measures in PD.Method62 PD patients and 42 age-matched controls completed traditional and iPad versions of the Trail Making Test (TMT) (executive function) and Knox Cube Test (visual memory), as well as a range of other measures.ResultsMedian age was 68 years; median MOCA score was 26. No participant had previously used an iPad. There was significant correlation between traditional and iPad measures: TMTa r=0.74, pConclusionThis initial study has demonstrated that two iPad-based measures of cognition are acceptable to PD patients and perform similarly to traditional pen-and-paper tests. Further work will extend the analysis of the measured indices in longitudinal studies to determine correlation with disease progression, and extend the battery of iPad-based tests available for PD assessment.
