Frailty and late-life depression are common in elderly people, and often present together. However, specialized treatments for individuals affected by both conditions are scarce. This study investigates the neural interactions of frailty and depression by applying structural and functional MRI of the brain, in conjunction with with sensor-based motion analysis (with a focus on habitual activity).
Our project aims to relate sedentary behavior, reduced behavioral activation and increased fatigability to abnormal brain structure and resting-state brain activity. The goal is to reveal common vs. distinct neuropathology in patients with frailty and/or late-life depression. Our study goals relate to the Research Domain Criteria (RDoC)-domains of positive valence systems and sensorimotor systems.
