Relationships between event-related potentials and neuropsychological tests in neurologically healthy adults.
Full Abstract
The aim of this study was to investigate the relationship between conventional neuropsychological tests and an event-related potential (P300). Subjects were 118 neurologically normal healthy adults 18-74 years old with no history of neurological, neurosurgical, or psychiatric disorders. We administered a neuropsychological test battery and recorded auditory P300 in all subjects. A significant correlation was seen between P300 latency and age, but not between amplitude and age. While significant negative correlations were apparent between some neuropsychological tests and age and P300 latency, stepwise regression analysis to assess the significance of each factor determined that age alone correlated with P300 latency. We therefore concluded that P300 measurements cannot be replaced by neuropsychological tests; rather, brain function should be evaluated by both methods.
