[Psychosomatic approach to patients with headache: alternative or integrated diagnoses?].

Each person has an inseparable body-mind unity, with psychic factors that can also manifest themselves through changes in the functions of the body, and with changing somatic states that contribute to mental experience. This explains why somatic symptoms fall within psychiatry. When a patient complains about physical symptoms, it is essentially an integrated, multidisciplinary diagnosis which is used to identify the various factors (biological and psychological) which worsen the disorder, and a psychiatric dimensional approach is used to integrate the descriptive symptomatic diagnosis with the psychostructural diagnosis. The same symptoms, in fact, may underlie different psychological dynamics that direct the treatment and determine the prognosis, as explained in three clinical cases that we described. The literature on headaches reports a high rate of co-morbidity between migraines and psychiatric disorders, but doesn't take into account the fact that often the symptom of headache is part of the disorder, even when it presents on its own. In conclusion, a holistic approach is needed for the patient to be diagnosed as having a "psychiatric" form of headache. A medical examination of the illness leading to a diagnoses is essential, according to the criteria of the International Classification of Headache Disease (ICHD-II). In clinical practice, we have integrated the descriptive diagnosis (ICHD-II mini-Plus) with the psychological (Diagnostic Criteria of Psychosomatic Research - DCPR) and psycho-structural (Kenberg's interview, Minnesota Multiphasic Personality Inventory - MMPI) diagnoses. The clarification of the dynamics underlying the definition of symptoms and the role played by psychological factors has influenced the identification of therapeutic objectives and in the identification of the most appropriate strategies.
