Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
A physician, medical practitioner, medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the science of medicine—and also a decent competence in its applied practice—the art or craft of medicine.
A profession is a field of work that has been successfully professionalized. It can be defined as a disciplined group of individuals, professionals, who adhere to ethical standards and who hold themselves out as, and are accepted by the public as possessing special knowledge and skills in a widely recognised body of learning derived from research, education and training at a high level, and who are prepared to apply this knowledge and exercise these skills in the interest of others.
Psychosomatic medicine is an interdisciplinary medical field exploring the relationships among social, psychological, behavioral factors on bodily processes and quality of life in humans and animals.
Thomas Stephen Szasz was a Hungarian-American academic and psychiatrist. He served for most of his career as professor of psychiatry at the State University of New York Upstate Medical University in Syracuse, New York. A distinguished lifetime fellow of the American Psychiatric Association and a life member of the American Psychoanalytic Association, he was best known as a social critic of the moral and scientific foundations of psychiatry, as what he saw as the social control aims of medicine in modern society, as well as scientism.
Medical anthropology studies "human health and disease, health care systems, and biocultural adaptation". It views humans from multidimensional and ecological perspectives. It is one of the most highly developed areas of anthropology and applied anthropology, and is a subfield of social and cultural anthropology that examines the ways in which culture and society are organized around or influenced by issues of health, health care and related issues.
Historically, mental disorders have had three major explanations, namely, the supernatural, biological and psychological models. For much of recorded history, deviant behavior has been considered supernatural and a reflection of the battle between good and evil. When confronted with unexplainable, irrational behavior and by suffering and upheaval, people have perceived evil. In fact, in the Persian Empire from 550 to 330 B.C., all physical and mental disorders were considered the work of the devil. Physical causes of mental disorders have been sought in history. Hippocrates was important in this tradition as he identified syphilis as a disease and was, therefore, an early proponent of the idea that psychological disorders are biologically caused. This was a precursor to modern psycho-social treatment approaches to the causation of psychopathology, with the focus on psychological, social and cultural factors. Well known philosophers like Plato, Aristotle, etc., wrote about the importance of fantasies, dreams, and thus anticipated, to some extent, the fields of psychoanalytic thought and cognitive science that were later developed. They were also some of the first to advocate for humane and responsible care for individuals with psychological disturbances.
Medieval medicine in Western Europe was composed of a mixture of pseudoscientific ideas from antiquity. In the Early Middle Ages, following the fall of the Western Roman Empire, standard medical knowledge was based chiefly upon surviving Greek and Roman texts, preserved in monasteries and elsewhere. Medieval medicine is widely misunderstood, thought of as a uniform attitude composed of placing hopes in the church and God to heal all sicknesses, while sickness itself exists as a product of destiny, sin, and astral influences as physical causes. On the other hand, medieval medicine, especially in the second half of the medieval period, became a formal body of theoretical knowledge and was institutionalized in the universities. Medieval medicine attributed illnesses, and disease, not to sinful behaviour, but to natural causes, and sin was connected to illness only in a more general sense of the view that disease manifested in humanity as a result of its fallen state from God. Medieval medicine also recognized that illnesses spread from person to person, that certain lifestyles may cause ill health, and some people have a greater predisposition towards bad health than others.
The treatise On Ancient Medicine is perhaps the most intriguing and compelling work of the Hippocratic Corpus. The Corpus itself is a collection of about sixty writings covering all areas of medical thought and practice. Traditionally associated with Hippocrates, the father of Western medicine, philological evidence now suggests that it was written over a period of several centuries and stylistically seems to indicate that it was the product of many authors dating from about 450–400 B.C.
The medical model of disability, or medical model, is based in a biomedical perception of disability. This model links a disability diagnosis to an individual's physical body. The model supposes that this disability may reduce the individual's quality of life and aims to diminish or correct this disability with medical intervention. It is often contrasted with the social model of disability.
Medicalization is the process by which human conditions and problems come to be defined and treated as medical conditions, and thus become the subject of medical study, diagnosis, prevention, or treatment. Medicalization can be driven by new evidence or hypotheses about conditions; by changing social attitudes or economic considerations; or by the development of new medications or treatments.
The sociology of health and illness, sociology of health and wellness, or health sociology examines the interaction between society and health. As a field of study it is interested in all aspects of life, including contemporary as well as historical influences, that impact and alter our health and wellbeing.
Behavioral medicine is concerned with the integration of knowledge in the biological, behavioral, psychological, and social sciences relevant to health and illness. These sciences include epidemiology, anthropology, sociology, psychology, physiology, pharmacology, nutrition, neuroanatomy, endocrinology, and immunology. The term is often used interchangeably, but incorrectly, with health psychology. The practice of behavioral medicine encompasses health psychology, but also includes applied psychophysiological therapies such as biofeedback, hypnosis, and bio-behavioral therapy of physical disorders, aspects of occupational therapy, rehabilitation medicine, and physiatry, as well as preventive medicine. In contrast, health psychology represents a stronger emphasis specifically on psychology's role in both behavioral medicine and behavioral health.
In medical anthropology, naturalistic disease theories are those theories, present within a culture, which explain diseases and illnesses in impersonal terms. George Foster explains naturalistic disease theory as following an "equilibrium model" in which health results from ideal balances of well being appropriate to one's age, condition, and environment. Imbalances in these systems result in illness through impersonal and systematic mechanisms. One example of a naturalistic disease theory is the theory expressed in western medicine or biomedicine, which links disease and illness to scientific causes. This leaves any personal liability for the disease out of the equation, and the diseases are attributed to organisms such as bacteria or viruses, accidents, or toxic substances.
Medical model is the term coined by psychiatrist R. D. Laing in his The Politics of the Family and Other Essays (1971), for the "set of procedures in which all doctors are trained". It includes complaint, history, physical examination, ancillary tests if needed, diagnosis, treatment, and prognosis with and without treatment.
Professionalization is a social process by which any trade or occupation transforms itself into a true "profession of the highest integrity and competence." The definition of what constitutes a profession is often contested. Professionalization tends to result in establishing acceptable qualifications, one or more professional associations to recommend best practice and to oversee the conduct of members of the profession, and some degree of demarcation of the qualified from unqualified amateurs. It is also likely to create "occupational closure", closing the profession to entry from outsiders, amateurs and the unqualified.
How Doctors Think is a book released in March 2007 by Jerome Groopman, the Dina and Raphael Recanati Chair of Medicine at Harvard Medical School, chief of experimental medicine at Beth Israel Deaconess Medical Center in Boston, and staff writer for The New Yorker magazine.
Traditional African medicine is a range of traditional medicine disciplines involving indigenous herbalism and African spirituality, typically including diviners, midwives, and herbalists. Practitioners of traditional African medicine claim, largely without evidence, to be able to cure a variety of diverse conditions including cancer, psychiatric disorders, high blood pressure, cholera, most venereal diseases, epilepsy, asthma, eczema, fever, anxiety, depression, benign prostatic hyperplasia, urinary tract infections, gout, and healing of wounds and burns and even Ebola.
Medical sociology is the sociological analysis of medical organizations and institutions; the production of knowledge and selection of methods, the actions and interactions of healthcare professionals, and the social or cultural effects of medical practice. The field commonly interacts with the sociology of knowledge, science and technology studies, and social epistemology. Medical sociologists are also interested in the qualitative experiences of patients, often working at the boundaries of public health, social work, demography and gerontology to explore phenomena at the intersection of the social and clinical sciences. Health disparities commonly relate to typical categories such as class and race. Objective sociological research findings quickly become a normative and political issue.
Eliot Freidson was a sociologist and medical sociologist who worked on the theory of professions. Charles Bosk says that Freidson was a founding figure in medical sociology who played a major role in the growth and legitimization of the subject. The American Sociological Society awards the Eliot Freidson Outstanding Publication Award for medical sociology every two years.
