Relationship between cognitive function and brain activation in late-life depression patients with and without frailty: a functional near-infrared spectroscopy study.
BACKGROUND AND OBJECTIVE Frailty and cognitive impairment commonly co-occur in late-life depression (LLD), but the task-evoked cortical alterations associated with frailty-related cognitive dysfunction in LLD remain unclear. We examined cognitive performance and cortical activation during a verbal fluency task (VFT) in...
