For the last couple of millennia, physicians and scientists across different civilizations have posited close links between the brain and heart, even arguing that the site of intelligence and emotions is in one of these two organs. Through an integrative empirical approach in modern biology/physiology and behavioral sciences, much has since been learned to confirm the anatomical and functional links between the brain and the heart. Arguably, the ultimate applicability of this knowledge will advance our health and improve disease treatment. \u0000 \u0000Modern medicine is characterized by a high degree of specialization, and the heart-brain connection is typically considered from the point of view of a particular medical specialty. Hence, focusing on the brain, for example, in neurology, cardiovascular involvement is critical in certain pathologies such as stroke and vascular dementia. In cardiology, on the other hand, the influence of the brain becomes clearly apparent in “the broken heart syndrome” (also known as acute stress cardiomyopathy). However, recent epidemiological studies point to new associations that typically present as co-occurring pathologies of both the brain and the heart. A case in point is the association between depression and coronary heart disease. Such co-occurrences have stimulated research into possible novel mechanisms that could be targeted to treat these complex cardiovascular/brain disorders. \u0000 \u0000At least three scenarios could be at play in these illnesses: (i) the primary pathological mechanism in the nervous system triggers a cardiovascular pathology by disrupting physiological links between the two systems (hence, the term “psychogenic”cardiovascular disease), (ii) the primary pathological mechanism in the cardiovascular system triggers a nervous system dysfunction (e.g., atherosclerosis leading to ischemic conditions causes subsequent cognitive impairment), and (iii) the primary pathology is in a biological mechanism that is normally operative in both the nervous and the cardiovascular systems, thus causing the co-occurrence of pathologies (i.e., the co-occurring pathologies share a pathobiological mechanism but do not necessarily cause each other). \u0000 \u0000To be successful, research in co-occurring cardiovascular and brain disorders needs contributions from multiple medical specialties, including psychiatry, neurology, medicine, and cardiology.
