Neurology is a branch of medical science that specializes in diagnosing and treating disorders of the human brain and nervous system. Common disorders addressed within the field of neurology include Parkinson's disease, Alzheimer's disease, strokes, ALS (Lou Gehrig's disease), brain and spinal cord injuries, multiple sclerosis, brain tumors and epilepsy.
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.
