There are 2 main classifications standards that are used today in the western world to diagnose psychopathological symptoms.

In the field psychotherapy, the concept of diagnostics is controversial. The reason being that unlike some physical problems, psychological issues are individual. For example, there is no one single cause of *borderline personality disorder (BPD), *but an array of situations that occur in the patient’s life that leads up to the symptoms. Diagnosing the symptoms are also complex, since each patient has his/her own way of dealing with the psychological trauma that leads to the condition. However putting labels onto observable psychological and behavioral conditions are necessary for professional to communicate with administrative bodies like psychiatrists, insurance companies, the courts, etc.
