Neurology is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the nervous system, which comprises the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system.
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.
Emergency medicine is the medical speciality concerned with the care of illnesses or injuries requiring immediate medical attention. Emergency physicians specialize in providing care for unscheduled and undifferentiated patients of all ages. As first-line providers, in coordination with emergency medical services, they are primarily responsible for initiating resuscitation and stabilization and performing the initial investigations and interventions necessary to diagnose and treat illnesses or injuries in the acute phase. Emergency medical physicians generally practice in hospital emergency departments, pre-hospital settings via emergency medical services, and intensive care units. Still, they may also work in primary care settings such as urgent care clinics.
In the medical profession, a general practitioner (GP) or family physician is a physician who treats acute and chronic illnesses and provides preventive care and health education to patients of all ages. GPs' duties are not confined to specific fields of medicine, and they have particular skills in treating people with multiple health issues. They are trained to treat patients to levels of complexity that vary between countries. The term "primary care physician" is more usually used in the US. In Asian countries like India, this term has been replaced mainly by Medical Officers, Registered Medical Practitioner etc.
Internal medicine, also known as general internal medicine in Commonwealth nations, is a medical specialty for medical doctors focused on the prevention, diagnosis, and treatment of internal diseases in adults. Medical practitioners of internal medicine are referred to as internists, or physicians in Commonwealth nations. Internists possess specialized skills in managing patients with undifferentiated or multi-system disease processes. They provide care to both hospitalized (inpatient) and ambulatory (outpatient) patients and often contribute significantly to teaching and research. Internists are qualified physicians who have undergone postgraduate training in internal medicine, and should not be confused with "interns", a term commonly used for a medical doctor who has obtained a medical degree but does not yet have a license to practice medicine unsupervised.
Hospital medicine is a medical specialty that exists in some countries as a branch of family medicine or internal medicine, dealing with the care of acutely ill hospitalized patients. Physicians whose primary professional focus is caring for hospitalized patients only while they are in the hospital are called hospitalists. Originating in the United States, this type of medical practice has extended into Australia and Canada. The vast majority of physicians who refer to themselves as hospitalists focus their practice upon hospitalized patients. Hospitalists are not necessarily required to have separate board certification in hospital medicine.
The American Academy of Family Physicians (AAFP) was founded in 1947 to promote and maintain high-quality standards for family medicine, an offshoot of the classical general practitioner. It is headquartered in Leawood, Kansas.
The American College of Physicians (ACP) is a Philadelphia-based national organization of internists, who specialize in the diagnosis, treatment, and care of adults. With 161,000 members, ACP is the largest medical-specialty organization and second-largest physician group in the United States, after the American Medical Association. Its flagship journal, the Annals of Internal Medicine, is considered one of the five top medical journals in the United States and Britain.
Family medicine is a medical specialty within primary care that provides continuing and comprehensive health care for the individual and family across all ages, genders, diseases, and parts of the body. The specialist, who is usually a primary care physician, is named a family physician. It is often referred to as general practice and a practitioner as a general practitioner. Historically, their role was once performed by any doctor with qualifications from a medical school and who works in the community. However, since the 1950s, family medicine / general practice has become a specialty in its own right, with specific training requirements tailored to each country. The names of the specialty emphasize its holistic nature and/or its roots in the family. It is based on knowledge of the patient in the context of the family and the community, focusing on disease prevention and health promotion. According to the World Organization of Family Doctors (WONCA), the aim of family medicine is "promoting personal, comprehensive and continuing care for the individual in the context of the family and the community". The issues of values underlying this practice are usually known as primary care ethics.
The American Osteopathic Association (AOA) is the representative member organization for the more than 176,000 osteopathic medical doctors (D.O.s) and osteopathic medical students in the United States. The AOA is headquartered in Chicago, Illinois, and is involved in post-graduate training for osteopathic physicians. Beginning in 2015, it began accrediting post-graduate education as a committee within the Accreditation Council for Graduate Medical Education, creating a unified accreditation system for all DOs and MDs in the United States. The organization promotes public health, encourages academic scientific research, serves as the primary certifying body for D.O.s overseeing 18 certifying boards, and is the accrediting agency for osteopathic medical schools through its Commission on Osteopathic College Accreditation. As of October 2015, the AOA no longer owns the Healthcare Facilities Accreditation Program (HFAP), which accredited hospitals and other health care facilities.
The Creighton Model FertilityCare System is a form of natural family planning which involves identifying the fertile period during a woman's menstrual cycle. The Creighton Model was developed by Thomas Hilgers, the founder and director of the Pope Paul VI Institute. This model, like the Billings ovulation method, is based on observations of cervical mucus to track fertility. Creighton can be used for both avoiding pregnancy and achieving pregnancy.
Addiction medicine is a medical subspecialty that deals with the diagnosis, prevention, evaluation, treatment, and recovery of persons with addiction, of those with substance-related and addictive disorders, and of people who show unhealthy use of substances including alcohol, nicotine, prescription medicine and other illicit and licit drugs. The medical subspecialty often crosses over into other areas, since various aspects of addiction fall within the fields of public health, psychology, social work, mental health counseling, psychiatry, and internal medicine, among others. Incorporated within the specialty are the processes of detoxification, rehabilitation, harm reduction, abstinence-based treatment, individual and group therapies, oversight of halfway houses, treatment of withdrawal-related symptoms, acute intervention, and long term therapies designed to reduce likelihood of relapse. Some specialists, primarily those who also have expertise in family medicine or internal medicine, also provide treatment for disease states commonly associated with substance use, such as hepatitis and HIV infection.
Adolescent medicine, also known as adolescent and young adult medicine, is a medical subspecialty that focuses on care of patients who are in the adolescent period of development. This period begins at puberty and lasts until growth has stopped, at which time adulthood begins. Typically, patients in this age range will be in the last years of middle school up until college graduation. In developed nations, the psychosocial period of adolescence is extended both by an earlier start, as the onset of puberty begins earlier, and a later end, as patients require more years of education or training before they reach economic independence from their parents.

It adopted its current name in 2005.
Reproductive endocrinology and infertility (REI) is a surgical subspecialty of obstetrics and gynecology that trains physicians in reproductive medicine addressing hormonal functioning as it pertains to reproduction as well as the issue of infertility. While most REI specialists primarily focus on the treatment of infertility, reproductive endocrinologists are trained to also test and treat hormonal dysfunctions in females and males outside infertility. Reproductive endocrinologists have specialty training (residency) in obstetrics and gynecology (ob-gyn) before they undergo sub-specialty training (fellowship) in REI.
