What this trial studies

This is a pilot randomized controlled trial enrolling 136 participants with Parkinson's disease or Huntington's disease and measurable anxiety symptoms. Half of participants will use the MindTrails-Movement app with daily cognitive bias modification for interpretation (CBM-I) training and nightly surveys for six weeks, while the waitlist control group uses a version of the app without CBM-I and completes the same surveys. Outcomes are collected at baseline, every two weeks during the 6-week intervention, and at a 4-week follow-up (week 10). The trial excludes people with cognitive impairment that prevents consent or use of the app, active suicidality, non-English speakers, those without an internet-connected device, and people living outside the USA.

Who should consider this trial

Good fit: Ideal candidates are adults in the USA with Parkinson's disease or Huntington's disease who have measurable anxiety symptoms, can consent, and can use a smartphone or tablet.

Not a fit: Patients with significant cognitive impairment, active suicidality, no regular internet-connected device, non-English speakers, or who live outside the USA are unlikely to benefit from or be eligible for this intervention.

Why it matters

Potential benefit: If successful, this could provide a low-cost, home-delivered way to reduce anxiety symptoms for people with Parkinson's and Huntington's disease.

How similar studies have performed: CBM-I approaches have produced modest anxiety reduction in general and some clinical populations, but mobile, tailored CBM-I for Parkinson's and Huntington's disease is relatively novel and not yet validated in larger trials.
