What this trial studies

This observational study aims to explore the mechanisms behind cognitive impairment and accelerated cognitive decline in individuals suffering from Late Life Depression (LLD). It will enroll 120 participants, including those from a previous study and new participants, over a 30-month period. Participants will undergo various assessments, including MRI scans and PET imaging, to gather data on brain function and biomarkers. Additionally, data from 300 non-depressed individuals will be utilized for comparative analysis.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of cognitive decline in older adults with depression.

How similar studies have gone: Other studies have shown promise in understanding cognitive decline in depression, but this specific approach is relatively novel.
