The World Health Organization warns that by 2020 depression will be the second most common disease in the world after cardiac health problems. Diagnosing depression is not difficult despite its many different forms. According to the Institute of Psychiatry and Neurology 14-16% of Poles have consulted a specialist in the past two years regarding depression, which is more than a few years ago. The two most common types of depression and their symptoms are:
Endogenous depression (clinical depression, severe depression) Caused by unspecified brain disruption, particularly hormonal and nervous system disorder followed by such symptoms as being in a depressed mood for most of the day, lack of positive thinking, drastic increases or decreases of weight, insomnia or excessive sleepiness, feeling tired, and dissociation.
Chronic depression (dysthymia) Depression lasts longer, and depressive symptoms go away for a short time only. One cause of dysthymia may be not adapting oneself to society in early childhood caused by a lack of security and self-confidence, traumatic events, or the inability to satisfy one’s needs and desires. The most common symptoms are a decrease or increase in appetite, feelings of tiredness or lack of energy, low self-esteem, and a sense of hopelessness.
