Subcortical evolution in HD
Key Investigators

Project Description
Objective
In the past we have estimated personalized growth models for a small number of HD subjects. For this project we want to estimated models for 84 subjects: 30 CTRL, 16 LOW, 24 MED, 14 HIGH. We want to explore individual models of sub-cortical change, as well as the evolution of white matter. We also want to test the robustness of the estimation by comparing the results estimated forward and backward in time.
Approach, Plan
Sub-cortical change in HD:
- Estimate individual models for all subjects and compare volume extracted from regression.
- Compare models estimated forward and backward in time to explore sensitivity to initial conditions.
White matter evolution:
- Prepare white matter surfaces for regression.
- Experiment on one subject as proof of concept.
- Prep all subject data for estimation -- start estimating models, though it likely won't finish during the project week.
