Understanding PTSD and depression from donated postmortem brain tissue with molecular analyses
2/3 Understanding PTSD through Postmortem Targeted Brain Multi-omics
['FUNDING_R01'] · LIEBER INSTITUTE, INC. · NIH-11330636
This project looks at molecular differences in brains donated by people who had PTSD, major depression, or no psychiatric disorder to find biological clues about why some people develop chronic PTSD.

What this research studies
Researchers will analyze brain tissue donated after death from people with PTSD, major depressive disorder (MDD), and matched controls. They will focus on brain areas tied to fear and mood regulation—like the amygdala, hippocampus, and dorsal raphe—and use multiple molecular methods (genotyping, DNA methylation, RNA analyses and other 'multi-omics') to profile changes. The work is a collaboration across three sites and will add about 300 new donated brains to build on prior data. Because the research uses postmortem tissue, it does not enroll living patients but may guide future diagnostic tests and treatments.
Who could benefit from this research
Good fit: Ideal candidates are people with a history of PTSD or major depression, and individuals without psychiatric illness, who or whose families are willing to consider brain donation after death.
Not a fit: People seeking immediate clinical treatment or living patients expecting direct therapy benefits should not expect direct or short-term personal benefit from this postmortem research.
Why it matters
Potential benefit: If successful, this work could reveal biological markers and pathways that help guide new diagnostics or targeted treatments for PTSD and related depression.
How similar studies have performed: Previous postmortem molecular studies have found promising leads, but comprehensive multi-omic comparisons across PTSD and MDD remain relatively new and are still generating foundational data.
