Brain Biomarker for Depression Found via Imaging – Newswise

Publication date: Jun 27, 2023

The researchers examined the functional connectivity among brain regions and mapped individual functional deviations in the MDD patients compared to this normative prediction across the lifespan. Researchers have recently begun making strides toward understanding the neurophysiology underlying different subtypes of depression, which could speed development of better treatments, but much remains to be discovered. The study used the so-called normative model, which uses data from a large reference population to quantify individual deviations, much like the growth charts used by pediatricians. The second subtype of patients featured a milder and opposite pattern of deviation, highlighting the heterogeneity of depression at the neurophysiological level. Dr. Xia went on to say, -These findings shed light on the diverse neurobiological mechanisms from a connectomics perspective underlying the complex clinical heterogeneity observed in individuals with depression. These biomarkers have the potential to guide future precise diagnostic and treatment strategies tailored to each patient’s specific neurophysiological subtype. ” The researchers used resting-state fMRI collected at multiple clinical sites from a large cohort of more than 1,000 MDD patients and over 1,000 healthy controls (HC).
