Causes of Depression

Many factors may play a role in depression, including genetics, brain biology and chemistry, and life events such as trauma, loss of a loved one, a difficult relationship, an early childhood experience, or any stressful situation.

Depression can happen at any age, but often begins in the teens or early 20s or 30s. Most chronic mood and anxiety disorders in adults begin as high levels of anxiety in children. In fact, high levels of anxiety as a child could mean a higher risk of depression as an adult.

Depression can co-occur with other serious medical illnesses such as diabetes, cancer, heart disease, and Parkinson’s disease. Depression can make these conditions worse and vice versa. Sometimes medications taken for these illnesses may cause side effects that contribute to depression.

A physician or therapist experienced in treating these complicated illnesses can help work out the best treatment strategy.
