People who suffer from this form of depression are often suicidal.However, this does not necessarily happen in every case of major depressive disorder.
However, the patient might also have a normal state of mind on many occasions.An individual may come out of mood swings, but a person suffering from depression requires long-term medical treatment, such as in the case of diabetes and high blood pressure.It is important to note that medication, counselling as well as other treatments bring about tremendous results in those suffering from this condition, by causing them to feel better about themselves.People who suffer from depression tend to sleep during the day, as they are unable to get sleep at night. Due to this, the affected person finds it hard to focus on anything throughout the day as he has been deprived of a good night's rest. Allen Israel have written about the involvement of genetic factors in the problem of depression.In some cases, the affected people might over-indulge in food and this might cause them to put on excess weight. This has been mentioned in their book, 'Behavior Disorders of Childhood'.
