Most of the time, depression is not just one cause, it is caused by the interaction of different factors. In the meantime, it is known that the messengers serotonin and norepinephrine play a role. If there is too little of them in the brain or their signals are not properly transmitted, depression develops.
How does depression develop?
On the other hand, one suspects a genetic component that is inherited - but only the predisposition to develop a depression may be inheritable, but not the actual expression. Then there are the factors that are different in every human being, such as social and psychological influences. On average, women are twice as likely to be affected as men.
Conversely, because the causes are so diverse, it also implies that in case-based research, it is necessary to give a detailed breakdown of which factors in the current situation of a person have probably led to depression - only then can these factors be changed and the factors affected Help sufferers in the long term.
How common are depression?
Depression is now so common that it speaks of a widespread disease. Current figures speak of about five to six million depressed people in Germany. It is estimated that over eleven percent of all people in Germany suffer from depression during their lifetime. In this case, the depressive phase can occur once (at about 25-40 percent), there may be several phases of the disease, between which the person is recovering - but unfortunately there is also a chronic course (at 10 to 15 percent).
Basically, the depression is a serious illness, because the sad mood can lead to disability or even suicidal thoughts. Thus, the disease for the person affected life-threatening, because as soon as the drive inhibition subsides, but the depressive mood remains, the path from suicidal thoughts to the real attempt is not far away. 40 to 70 percent of all suicides are carried out in the context of depression and almost every patient with a major depression has at least suicidal thoughts.
