Task Evoked Pupillary Response Reflects Task Complexity in Parkinson ’s Disease: A Pilot Study

Task-evoked pupillary response (TEPR), a neurophysiological measure of cognitive workload, is increasingly used to detect subtle cognitive impairments in non-demented individuals with Parkinson ’s disease (PD). However, the relationship between TEPR and task complexity in non-demented PD remains unclear. The aim of this study was to examine the relationship between TEPR and task complexity in non-demented individuals with PD and healthy controls.
