Geriatrics or Geriatric Medicine is health care of elderly people. It aims to promote health by preventing and treating diseases and disabilities in older adults. It is important to note the difference between geriatrics, the care of aged people, and gerontology, which is the study of the aging process itself. The term geriatrics comes from the Greek γέρων geron meaning "old man", and ιατρός iatros meaning "healer". However, geriatrics is sometimes called medical gerontology.

Doctor of Osteopathic Medicine (D.O. or DO) is a professional doctoral degree for physicians and surgeons offered by medical schools in the United States. Holders of D.O. degrees can become licensed as Osteopathic Physicians who have equivalent rights, privileges, and responsibilities as physicians with a Doctor of Medicine degree (M.D.). One notable difference between D.O. and M.D. training is that D.O. training adds 300 - 500 hours studying techniques for hands-on manipulation of the human musculoskeletal system. Physician Assistants (also known as PAs) are trained medical practitioners who work in teams with physicians, surgeons, and other healthcare workers. They examine, diagnose, and treat patients under the supervision of a doctor.
