[Is there more than one "true" theory of cognition in medicine?]

Alternative approaches such as Traditional Chinese Medicine are very popular with patients. Often, however, there is a lack of high quality studies to prove their efficacy. The question will be discussed whether different theories of cognition may coexist in medicine which are all true. Not only biological, but also psychological and social factors contribute to health and well-being. Integrative medicine should bridge the gap between mainstream evidence-based medicine and complementary methods. Shared decision making between patient and physician can help to find the optimum, often multimodal treatment strategy for each patient.
