The contributed volume "Multidisciplinarity and Interdisciplinarity in Health" is a health-centered volume of the Integrated Science Book series. Lack of confidence, lack of expertise, complexities of healthcare, the confusing nature of healthcare environments, and lack of organization and standardization can become obstacles to successful communication. This volume establishes how extensive is the interface between formal sciences and medical sciences on health-related issues. The book provides an overview of the value of the integration of formal, biological, and medical sciences and related products, i.e., health informatics and biomedical engineering, to frame a holistic approach to health systems, healthcare, medical practice, drug discovery, and medical device design. The book also focuses on innovative solutions to the most critical issues of different health crisis, including obesity, infectious outbreaks, and cancer that can be found by using an integrative approach. It also contains the fascinating crossroads between medical sciences, physics, and mind that is discussed from multiple perspectives on cognition, neuroscience, and psychiatry. These multidisciplinary considerations will expand the concepts of creativity, leadership, aesthetics, empathy and mental health.
