Can depression be genetic?

You may know or notice that a family member struggles with depression. Being by a loved one’s side and watching their struggle with depression may have you wondering about any possible genetic links. You may be asking, if my family member has depression, will I experience it too?

The most common form of depression is major depressive disorder or MDD. Present information shows that about 10 percent of Americans will experience MDD at some point and that MDD is more likely to be shared by siblings and children. Someone with a relative who has depression is about five times more likely to develop it than someone who doesn’t have a relative with depression. Still, these numbers don’t necessarily reflect just a genetic basis for depression. There are multiple factors involved in the development and presentation of depression.

Researchers have studied depression for a genetic link. At present, both genetic factors and environmental factors are thought to contribute to depression. Family links may not be just about shared genes but also about the influence of behavior modeling and the shared environment. For example, a child that grows up watching a depressed parent or sibling exhibit certain behaviors and thinking patterns may learn those behaviors and patterns of thinking.

Some studies have also linked the neurotransmitter serotonin to depression. It is thought that an imbalance in serotonin can lead to disorders like depression. Within the serotonin, the link may be a genetic link as well. Researchers have found that the serotonin transporter gene may be a factor.

Depression is treatable with both therapy and medication used separately or together. For some people, depression may ebb and flow over life. Depression can be a temporary problem or a condition that requires lifelong management. Awareness is very important in managing depression. Notifying your medical doctor of symptoms and symptom changes and talking about these with your therapist as soon as possible can help adjust treatment plans and ensure your treatment is effective.

If you are experiencing symptoms of depression, visit your medical doctor and mental health provider about treatment options as soon as possible.
