Neurology is a medical specialty dealing with disorders of the nervous system. Specifically, it deals with the diagnosis and treatment of all categories of disease involving the central, peripheral, and autonomic nervous systems, including their coverings, blood vessels, and all effector tissue, such as muscle. Neurologists are trained to investigate, or diagnose and treat, neurological disorders.
Neurological disorders are disorders that can affect the central nervous system (brain and spinal cord), the peripheral nervous system, or the autonomic nervous system.
Neurosurgery is the surgical discipline focussed on treating those central, peripheral nervous system and spinal column diseases amenable to surgical intervention.
