Only some of the main symptoms of cyclothymic depression can be considered as autochthonic. The syndrome which usually constitutes the clinical picture of cyclothymia, and determines its transformation in the course of time, is the result of the patient’s coping patterns with the impairments caused by the illness and the modifications of the expectations of those with whom they interact. At the beginning, both sides try to keep the behavioral nonconformity below the level of social perception. Later on, the environment reacts to the behavioral disorder of the patient, branding him as mentally ill, and finally, the patient finds in his depressive delusions a new pseudo-identity, which allows him through his delusionally newly adopted role to create new interactional relationships, and in this way to achieve a partial come back to social life.
