NEUROLOGY.

Neurology is a rapidly developing branch of medicine dedicated to the diagnosis and treatment of disorders involving the brain, spinal cord, nerves, and muscles. The nervous system is crucial to human life. Understanding its operation under normal and pathological conditions is the focus of a group of disciplines that includes neurology, neuroscience, neurosurgery, and psychiatry. Considerable overlap and interaction exist between these specialties. Among the most important and challenging neurological disorders are neurodegenerative conditions (such as Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis), stroke, brain tumors, epilepsy, migraine, and multiple sclerosis.
