What are the symptoms of depression

Most of us have moments or short periods of sadness when we feel lonely or depressed. These sensations are usually normal ones that sometimes occur in life. They can be the result of a recent loss, having a particularly challenging day or week, or a reaction to a hurtful comment. However, when feelings of sadness and being unable to cope overwhelm the person, so much so that they undermine their ability to live a normal and active life, it is possible that they have what is known as a major depressive disorder (MDD), also called clinical depression, unipolar depression or major depression. Informally, the condition is simply referred to as depression. Depression can have a major negative impact on a sufferer\'s life - experts say the effect is comparable to that of diabetes, and some other chronic conditions. Depressive symptoms vary significantly between people. Most commonly, the person with depression feels hopeless, sad, and has lost interest in doing the things that were once pleasurable. What is the difference between a sign and a symptom? - A symptom is something felt by the patient, such as a headache, while a sign is detected by other people too, such as a rash.
