Medicine is the science and practice of establishing the diagnosis, prognosis, treatment, and prevention of disease. 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.

Medicine has been around for thousands of years, during most of which it was an art (an area of skill and knowledge) frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancient philosopher and physician would apply bloodletting according to the theories of humorism. In recent centuries, since the advent of modern science, most medicine has become a combination of art and science (both basic and applied, under the umbrella of medical science). While stitching technique for sutures is an art learned through practice, the knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science.

Prescientific forms of medicine are now known as traditional medicine and folk medicine, though they do not fall within the modern definition of “medicine” which is based in medical science. Traditional medicine and folk medicine remain commonly used with, or instead of, scientific medicine and are thus called alternative medicine (meaning “[something] other than medicine”, from Latin alter, “other”). For example, evidence on the effectiveness of acupuncture is "variable and inconsistent" for any condition, but is generally safe when done by an appropriately trained practitioner. In contrast, alternative treatments outside the bounds not just of scientific medicine, but also outside the bounds of safety and efficacy are termed quackery. Quackery can encompass an array of practices and practitioners, irrespective of whether they are prescientific (traditional medicine and folk medicine) or modern pseudo-scientific, including chiropractic which rejects modern scientific germ theory of disease (instead believing without evidence that human diseases are caused by invisible subluxation of the bones, predominantly of the spine and less so of other bones), with just over half of chiropractors also rejecting the science of immunization.

Multiple sclerosis (abbreviated MS, also known as disseminated sclerosis) is a chronic, inflammatory disease that affects the central nervous system (CNS). MS can cause a variety of symptoms, including changes in sensation, visual problems, muscle weakness, depression, difficulties with coordination and speech, and pain. Although many patients lead full and rewarding lives, MS can cause impaired mobility and disability in the more severe cases. Multiple sclerosis affects neurons, the cells of the brain and spinal cord that carry information, create thought and perception and allow the brain to control the body. Surrounding and protecting some of these neurons is a fatty layer known as the myelin sheath, which helps neurons carry electrical signals. MS causes gradual destruction of myelin (demyelination) and transection of neuron axons in patches throughout the brain and spinal cord, causing various symptoms depending upon which signals are interrupted. The name multiple sclerosis refers to the multiple scars (or scleroses) on the myelin sheaths. It is thought that MS results from attacks by an individual's immune system on the nervous system and is therefore categorized as an autoimmune disease. (More...)
