An intensivist is a medical practitioner who specializes in the care of critically ill patients, most often in the intensive care unit (ICU). Intensivists can be internists or internal medicine sub-specialists (most often pulmonologists), anesthesiologists, emergency medicine physicians, pediatricians (including neonatologists), or surgeons who have completed a fellowship in critical care medicine. The intensivist must be competent not only in a broad spectrum of conditions among critically ill patients but also with the technical procedures and equipment (i.e. mechanical ventilators) used in the intensive care setting.

Neurology is a branch of medicine dealing with disorders of the nervous system. Neurology deals with the diagnosis and treatment of all categories of conditions and disease involving the central and peripheral nervous systems (and their subdivisions, the autonomic and somatic nervous systems), including their coverings, blood vessels, and all effector tissue, such as muscle.

A neurologist is a physician specializing in neurology and trained to investigate, or diagnose and treat neurological disorders. Neurologists treat a myriad of neurologic conditions, including stroke, seizures, movement disorders such as Parkinson's disease, autoimmune neurologic disorders such as multiple sclerosis, headache disorders like migraine and dementias such as Alzheimer's disease.
