Neurology is the study of the nervous system, encompassing brain, spinal cord and the peripheral nervous system, as well as the musculature of the human body.
The neurologist knows about all the deformities and disorders of the nervous system and musculature, and what can go wrong with them. This includes migraine, epilepsy, multiple sclerosis, Parkinson's disease as well as chronic sleep disorders and difficulties with movement.
The neurologist has received special training in the various methods of examination used to diagnose the above conditions. He can, for example, measure electrical activity in the brain or extract and examine fluids from the spine.
A neurologist treats his patients with medication. If an operation is needed, the patient will be transferred to the neurosurgeon.
