* Doctor of Medicine (MD): This is a professional degree awarded after completing medical school. It's a terminal degree in the sense that it qualifies a graduate to practice medicine. It focuses on the clinical application of medical knowledge and the development of clinical skills. Further specialization typically requires residencies and fellowships.
* Doctorate in Medicine (Dr.Med., or similar): This can refer to several things, but generally implies a research-focused doctoral degree in a specific area of medicine, such as medical science or a particular medical specialty. It's usually earned *after* an MD or equivalent professional degree and focuses on original research contributions to the field. While it might not directly qualify someone to practice medicine (depending on the country and specific degree), it signifies advanced expertise and research capabilities. Examples might include a PhD in a medical field.
In short:
* MD: Focuses on clinical practice. A professional degree.
* Doctorate in Medicine (Dr.Med., etc.): Focuses on research and advanced study within medicine. A research degree, often built upon an MD or equivalent.
The distinction is less relevant in many contexts, as someone with an MD is also referred to as a "doctor" and holds a doctorate. The crucial difference lies in the *emphasis* of the degree: clinical practice versus research.
