It is hard to understand that a mental disorder like depression stems from certain hereditary causes. However, medical studies have testified that the genes do have a very important role to play in carrying depression from generation to generation. Often, external factors are also responsible for a mental disorder like depression. Depression can also spring from some other disease or ailment and sometimes even from addictions. Addiction is a term that is mostly used in the negative sense and the term is not just limited to dependence on addictive substances.

The term addiction can also be applied to helpless dependence on any habit or manner. There are many instances when a person moves ahead to complete a particular task in spite of knowing that what one is doing is wrong and detrimental to the interests of either the self or others. Addiction of either a substance or a habit and the knowledge that the addiction is bad is also a very potent cause of depression. There are people who derive some kind of sadistic pleasure from addictive dependence on a particular deed. Some among these people who derive pleasure by hurting others are termed psychopaths. Altogether, when people can't abstain from doing things that they consider to be wrongful, they are considered to be under the influence of a specific addiction. Depression creeps into the psyche of these people unknowingly.

However, addiction, depression and bad memories are interrelated in many cases. In many people, it is seen that a bad memory leads to some form of addiction and eventually triggers off depression. Depression is very much a curable disease. But when depression is related to some other problem, the cure is easier said than done. People who are suffering from multiple disorders sometimes seem to be very normal. It becomes hard to decipher that they are in the grip of mental problems. This is altogether very dangerous. Seemingly normal human beings who are actually sick are really dangerous to themselves and also to the ones around them. It is also hard to influence these people into opting for treatment because they feel that they are alright. In many cases, the patient knows that he is sick but acts otherwise in front of the world. These patients can go for depression drugs that are available online in case they feel embarrassed to accept their illness in public. Xanax is one of them and a patient can from a reputed online pharmacy. In order to , however, is necessary.

Coming back to the original topic of other illnesses or conditions being interrelated with depression, early treatment is the only option before it is too late. To quote an example, recently a man named Joseph Fritzl was caught in Austria for having forceful sexual relationship with his own daughter for period of 24 long years and fathering 7 children from her. The daughter Elizabeth was locked up in the cellar of their house and was raped for 24 years by her own father. The guilty, when caught, admitted that all the time he knew that what he was doing was wrong but he couldn't control himself. He was addicted to doing it. The guilty had a rough childhood and was afflicted with mental disorders though one cannot be sure whether it was depression. In this case, a proper early evaluation of Joseph Fritzl`s mental disorder and subsequent treatment might have been able to restrain him from committing the heinous crime.
