Cognitive processes of apathy in Huntington's disease show high sensitivity to disease progression.

ABSTRACT:

Background

Disease-modifying treatments for Huntington's disease (HD) are entering clinical trials: there is a pressing need for objective outcome measures of disease progression. Our previous work showed an association between 2 novel, objective cognitive tasks and apathy - a core feature of disease progression in HD.

Objective

Evaluate the longitudinal validity and sensitivity of the novel Persistence and Maze tasks to assess their utility as clinical outcome measures in HD.

Methods

83 participants positive for the HD gene and 54 controls performed a battery of established and novel tools, at baseline and 12 month follow up.

Results

The Maze task was found to be the most sensitive measure of change at 12 months, including the current gold-standard measure (th
