About Neurology

Neurology is the field of medicine that specializes in disorders and diseases of the brain, nerves and spinal cord, which all okay an extremely vital role in every process of the body. Neurologists diagnose and treat a variety of neurological disorders using various skills and techniques honed during residency training and post-residency practice.

Neurologists are trained to diagnose and treat headaches and migraines, epilepsy, neuralgia, carpal tunnel syndrome, Bell’s palsy, brain and spinal cord injuries, Parkinson’s disease, multiple sclerosis, Lou Gehrig’s disease, Huntington’s disease, complications resulting from strokes, transient ischemic attacks, subdural hemorrhage and hematoma and infectious disease-related neurological disorders (such as those resulting from meningitis, encephalitis, or polio), among many others.

Neurologists diagnose these conditions through laboratory tests (such as blood and urine tests, genetic DNA tests, or spinal and brain fluid tests), angiographies, biopsies, general neurological examinations, x-rays, fluoroscopies, brain scans, cerebrospinal fluid analyses, CT scans, discographies, cisternographies, EKGs (electrocardiograms) or EEGs (electroencephalograms), and many procedures. Depending upon the diagnosis and specific disorder, neurologists may employ any of the following treatments: brain mapping, CyberKnife™ and Gamma Knife™ radiosurgeries, preventive measures, therapy, medication, lifestyle changes and rehabilitative procedures, among others.

Neurology Education & Training

Training to become a neurologist requires the completion of a demanding and arduous program of study. The educational track commences with the completion of a bachelor’s degree and a four year MD or DO degree from a medical school. Following graduation from medical school, the physician must complete a one year internship before entering a three year neurology residency. During the residency, the physician is trained and supervised by experienced neurologists in the diagnostic and treatment techniques pertinent to the specialty.

Following successful completion of the residency, the physician may seek certification in neurology from the American Board of Psychiatry and Neurology (ABPN), as well any additional requisite licenses or certifications. Neurologists may pursue additional training and education to become board certified in a specialized area of neurology, such as pediatric neurology or geriatric neurology, by completing a specialized fellowship program.

Neurology Symptom Guide


Welcome to this symptom guide about tinnitus. We're sorry to hear you have this problem!

While tinnitus is often called ringing in the ears, that's just one way people with tinnitus describe the problem. Others describe hearing a hissing, whooshing, roaring, or buzzing sound, or experiencing a beating sensation in the ear. So, for the purposes of this guide, we'll stick with the more general term, tinnitus.

There are a number of causes of tinnitus. This guide will cover some of the most common, but it is not exhaustive; rarer causes will not be covered. In addition, tinnitus results from just about any cause of hearing loss. For example, excessive buildup of wax in the ears may cause hearing loss and tinnitus. However, this guide will focus on tinnitus rather than hearing loss.

By answering a short series of questions, you will learn about the more common reasons for tinnitus and the cause that most likely applies to you. This guide is not intended to replace a face-to-face meeting with your doctor about these symptoms. Many causes of tinnitus require an in-person examination and testing to diagnose.

Let's get started.
