Summary
Depression is a common mental health condition that runs in families, but not necessarily means you will inherit it. Twin and family studies suggest that heritability is around 40% to 50%, and may be even higher for severe depression. Genome studies have identified 178 gene variants linked to major depression, and people with a higher genetic risk can take protective factors such as cultivating the right home environment, getting enough sleep, and eating nutritious foods.
