Investigating brain imaging biomarkers in late-life depression

PET-MRI Biomarkers of Pathological Brain Aging in Late-life Depression

Observational Universitaire Ziekenhuizen KU Leuven · NCT03849417

This study looks at how brain scans and behavior are connected in older adults with depression to see if it helps us understand their condition and the effects of treatment.

What this trial studies

This observational study explores the relationships between PET-MRI brain imaging biomarkers and behavioral measures in patients with late-life depression compared to healthy controls. It includes a cross-sectional analysis of 64 patients with late-life depression and 64 healthy individuals, as well as a longitudinal evaluation of 20 patients undergoing electroconvulsive therapy (ECT). The study aims to clarify how various brain biomarkers, such as synaptic density and tau pathology, relate to neuropsychological function and the effects of ECT. The findings could enhance our understanding of the neurobiology underlying late-life depression and its treatment.

Who should consider this trial

Good fit: Ideal candidates are individuals over 60 years old diagnosed with late-life depression.

Not a fit: Patients with a history of major neurological disorders or significant psychiatric diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and treatment strategies for late-life depression.

How similar studies have performed: Other studies have shown promise in using neuroimaging to understand depression, but this specific approach is relatively novel.
