This belief may stem from ignorance, misunderstanding or the attitude of downplaying problems. In everyday language, depression is often referred to as a short, transient state of sadness or downheartedness. In medical terms, depression comprises a set of symptoms, which include depressed mood and activity, sleep disorders, anxiety, depressive assessment of the future and the past, discouraged attitude to life, diminution of interests, withdrawal from life. These symptoms can not be treated as a whim; especially because depression may also be joined by suicidal thoughts and attempts, which can be life threatening.
It is also worth knowing that approximately 10% of all adults suffer persistent depressive mood disorders during a single year. Although some of them are probably trying to deal with depression on their own, it does not change the fact that depressive disorders are among the most common health problems. If one takes into account the consequences of depression, then depression is comparable with diseases most often treated by contemporary medicine (cardiovascular diseases, degenerative diseases of the musculoskeletal system, cancer).
For the last several years, in almost all developed European countries a marked increase in the number of people treated for depression is observed.
