Treatment of Overthinking: A Multidisciplinary Approach to Rumination and Obsession Spectrum.

Classic psychiatry patients are rare; real-world patients tend to have overlapping features of multiple disorders. Striving for diagnostic certainty, and treatments aimed at tentative diagnoses, often fail these patients. In such cases, tolerating diagnostic ambiguity and "treating the symptoms" can sometimes be transformative. An important symptom, often undertreated in a diagnosis-based approach, is rumination. We present a case study of a woman who, after 20 years of treatment failure, achieved significant symptom relief when her primary complaint-"labored thinking"-was targeted specifically. However, because no seriously ill person has only 1 symptom, 6 clinicians from different subdisciplines will discuss the patient's other issues, ones that an overfocus on rumination might leave out.
