When we talk about depression, many of us would think about it as a mood or feeling of disappointment or loss, rather than as a disease. However, if such depression stays around for a long time or is accompanied by other symptoms, then we might need to consider the possibility of depressive illness.
Depressive illness is associated with many factors including genetics and changes of certain substances in your brain. Changes may be seen with depressive illness, either gradually or rapidly within 1-2 weeks. Major changes that can be seen are changes of mood, crying more often, feeling bad with everything they experience, and feeling worthless. Patients with depressive illness tend to keep themselves isolated and may not talk to anyone. In some severe cases the symptoms may include mental disorder symptoms such as delusions or hallucinations.
