Telomere length

What are telomeres?

Telomeres are protective caps on the ends of chromosomes. They are linked to aging as they shorten with each cell division, and when they reach a critical length, the cell stops dividing or dies. Chronic stress has been associated with reduced telomere length, resulting in the recognition of an association between adverse social and environmental influences and accelerated aging.

What is the evidence for changes in telomere length in people with PTSD?

Moderate to high quality evidence found a small effect of shorter telomere length in people with PTSD compared to controls.
