Introduction In this paper, I shall discuss the differences between diagnosis and disease/ disorder. As I have a limited number of words, I shall try to avoid from a reductionist perspective. However, the topic is a topic that is very open to discussion that's why I am going to try to reflect my ideas with the synthesis of philosophers and psychologists' ideas. Discussion Firstly I shall explain what is the main difference between diagnosis and disease to me. The diagnosis is a human-made concept and the disease is a situation it is pure reality. From my point of view, Micheal Foucault’s thoughts on that issue were revolutionary and sensational ideas for the world of psychology and If I supposed, to be honest, his thoughts on both psychology and political philosophy really impress me. I touched upon Foucault because it is a thing that disturbs me ‘’ definition of normal’’. The things which are human-made changes always and open to discuss and they are all political. As we all know until the American Psychiatry Association decided that homosexuality is not a sickness or emotional disease in 1973. (although they explained it we know that WHO removed homosexuality from the diseases list in 1990.) but the reflections of the era that homosexuality accepted as a sickness is still continuing. Homosexuality is a reality. Saying sickness to that is a normative human-society made behavior and who may give the account for the inhuman treatment to the LGBTI+ people who were seen as sick. Their families were told they were sick and the violence that they exposed by family or society is unimaginable. So we can not see the future, how DSM is going to change how definitions are going to progress. Who decides what is the main issue according to my opinion. As members of psychologists, all we have to do is never forget sympathies and forget the humanitarian values while treating to the client.
