Psychosomatic medicine emerged in Italy in the late 1950s. Key figures such as Ferruccio Antonelli, who founded the first Italian journal dedicated to the field, played crucial roles. The establishment of the Società Italiana di Medicina Psicosomatica in 1966 marked a significant milestone, bringing together experts from diverse medical backgrounds. Throughout the 1960s and 1970s, the field grew through international conferences and the publication of influential scientific works. Despite its early success, psychosomatic medicine faced challenges in the 1980s and 1990s, particularly due to changes in diagnostic criteria with the release of DSM III, which did not include psychosomatic syndromes. This period saw a decline in the discipline’s prominence. However, the establishment of the Diagnostic Criteria for Psychosomatic Medicine in 1995 provided new frameworks for understanding and diagnosing psychosomatic conditions. In 2004, the Research Group on Psychosomatics was founded, promoting a holistic, biopsychosocial approach to health. Today, psychosomatic medicine in Italy is supported by regional initiatives and international collaborations. Despite ongoing challenges, such as a lack of formal recognition and standardized care pathways, the field continues to evolve, emphasizing the importance of comprehensive patient care and interdisciplinary collaboration. Future efforts aim to fully integrate psychosomatic medicine into clinical practice and education.
