Pupillary response to light and tasks in early and late onset essential tremor patients

Late-onset essential tremor is characterised by shorter life expectancy and more advanced aging parameters and may therefore be an ‘aging-related’ tremor. Brainstem functions involved in pupillary responses are hypothesized to reflect such earlier aging. The pupillary light response (PLR) and a task evoked pupillary response (TEPR) were used to test this hypothesis in same-aged patients with early onset (EOET) and late onse t (LOET) essential tremor and healthy controls.
