Depression is complex
All human brains can experience depression, but there is more than one kind of depression. The most common depression is situational where a person goes through a downswing due to a life experience. This depression can often be treated by therapy that is specific to the event, such as grief counseling. In contrast, unipolar and bipolar depression are considered genetic, medical conditions. They often occur without a life experience trigger and usually need a more medical than therapy-based treatment approach.
