Dual task paradigms are gaining traction as a means of detecting subtle cognitive deficits. By dividing performance between 2 separate tasks, they can highlight early cognitive changes, possible hallmarks of later deterioration. In the literature on dementia, dual task conditions differentiate between healthy controls and those with mild cognitive impairment, despite equivalent performance in single task conditions.1 In multiple sclerosis (MS), these early markers look increasingly advantageous. Roughly half of all people with MS go on to develop cognitive impairment, and with this comes increased risk of unemployment, social difficulties, and reduced quality of life.
