Depression is a very common mental health condition. According to the National Institute of Mental Health (NIMH), around 17.3 million adults in the U.S. experience at least one major depressive episode. Female-identifying patients are also more likely to be diagnosed with depression when compared to male-identifying patients. Age can also play a role, as higher rates of depression are recorded among patients aged 18 to 25. Depression is also more common among people who identify as two or more races.
