Let's talk about Depression
What is depression?
Everyone can sometimes experience sadness, guilt, and other negative emotions in response to life’s ups and downs. But people with depression may experience negative emotions and other mental and physical symptoms that are intense, don’t go away over time, and make it hard to carry on the normal activities of daily life. The causes of depression are complex and not completely understood, but they are thought to include both biological differences in things like genetics, brain chemistry, and hormones, as well as life experiences and environmental stressors.
If you have been diagnosed with depression, know that you’re not alone. Depression is very common. About 1 in 5 people in the U.S. will be diagnosed with depression during their lifetime.
What are the symptoms of depression?
Depression symptoms can range from mild to severe, and may vary from person to person. Some common symptoms can include:
* Feeling sad, empty, hopeless, irritable, guilty, or other difficult emotions
* Loss of interest or pleasure in activities you used to enjoy
* Decreased energy
* Difficulty thinking or concentrating
* Difficulty sleeping or oversleeping
* Loss of or increase in appetite
* Aches and pains like headaches, backaches, or digestive symptoms that do not respond to treatment
* Thoughts of harming oneself, death, or suicide
Is depression genetic?
The likelihood of experiencing depression is impacted by many factors, both non-genetic and genetic. Some people may be more likely to experience depression than others, depending on their genetics. Depression can run in families, which means that a person has an increased chance of having depression if family members have the condition. A combination of many different genetic variants impact a person’s chances of experiencing depression. Individually, each of these variants only has a small impact on a person’s genetic likelihood, but that impact can grow when many variants are considered together. 23andMe takes into account more than 8,400 genetic markers to estimate the likelihood of having been diagnosed with depression.
Depression is also impacted by many non-genetic factors. Genetics combine with other factors to influence an individual’s overall likelihood of developing depression. Examples of non-genetic factors can include:
- Many health conditions, including other mental health conditions
- Stressful life events
- Social isolation or lack of support
- Problems with alcohol, tobacco, or drug use
- Having a family history of depression or other mental health conditions
- Childhood adversity or maltreatment
- Experiencing discrimination due to race, sexual orientation, gender expression and identity, or other factors
- Gender: Cisgender women and transgender and non-binary individuals are more likely to be diagnosed with depression
What are some ways to manage depression?
While depression is impacted by some factors that can’t be changed—like genetics—it’s also impacted by some things that can, including lifestyle habits. Some healthy habits that can help people manage depression symptoms include:
- Seek social interaction and support from family, friends, and/or a counselor or other mental health professional. This is especially important during times of stress, such as major life changes or losses.
- Do your best to get active—exercise is very effective at improving mood.
- Practice good sleep habits, such as keeping your bedroom dark at night and getting sunlight during the day to strengthen your circadian rhythms.
- Explore stress-reduction and/or mindfulness techniques like meditation or yoga.
- Avoid using alcohol and tobacco, and if needed, consider getting help to quit.
- Engage in hobbies and other activities that are pleasurable, like getting a pet, listening to music, and spending time in nature, which have also been found to improve mood.
- Don’t face depression alone. Talk to a healthcare professional. Most cases of depression respond well to treatment with counseling, medication, or a combination of the two.
If you have any concerns or feel depressed, please reach out to a loved one or a healthcare professional like a primary care provider, clinical psychologist, mental health counselor, or genetic counselor.
