Full Answer

Neurology is a broad field of modern medical science that includes research and treatment across a wide range of issues dealing with the human brain and nervous system. Because the brain and nervous system are so complex, there are many sub-fields and specialties within the broader scope of neurology. Neurologists analyze and diagnose, but do not perform surgery.

Neurologists utilize a variety of methods and technologies to diagnose disorders of the brain and nervous system. Some of these include CAT scans, in which X-rays and computers are used to generate multidimensional images of the brain; magnetic resonance imaging, or MRI, in which magnetic fields and radio waves are used to take photographs of the inner brain; transcranial doppler, or TCD, in which sound waves are used to analyze blood flow in the brain; neurosonography, in which blockages in the blood vessels of the brain are located using high-frequency sound waves; and electroencephalograms, or EEGs, in which electrodes are attached to a patient's scalp in order to record the brain's electrical activity.
