Neurology is a branch of medicine dealing with the diagnosis and treatment of nervous system disorders. Neurology deals with all categories of conditions and diseases affecting 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.

Neurology practice relies heavily on the field of neuroscience, which is the scientific study of the nervous system. Clinical neurology specialists offer medical and diagnostic care for many neurological conditions. These conditions may include: blackouts and seizures, dizziness, headaches including migraine, memory or concentration loss, muscle weakness and pain, numbness or tingling, sleep disorders, speech deficits, spinal cord injury, tremors and twitches, unsteadiness, vision changes and more.
