When you breathe, think, laugh or lift your finger, your brain and nerves are communicating through electrical impulses transmitted by nerve cells. Neurology involves your entire nervous system - the internal wiring that controls your body's function and movement. When an illness or injury disrupts the proper working of this complex system, chances are you'll need to see a neurologist.

Your primary care provider will refer you to a neurologist who will provide principal care to patients with neurological disorders such as Parkinson’s disease, Alzheimer’s disease, multiple sclerosis or stroke.

Neurologists are physicians who diagnose and treat disorders of the brain, spinal cord and nervous system. They also evaluate patients with muscle diseases. Many neurologists focus on specific conditions, such as multiple sclerosis or stroke. A neurologist does not perform surgery, but works closely with your primary care doctor and a surgeon, if needed, to guide you through your treatment.

If you've experienced any of these symptoms, talk to your doctor:

• Unexplained headaches
• Dizziness
• Persistent back and neck pain
• Memory loss
• Seizures
• Muscle weakness, numbness or tingling

Your neurologist will perform a neurological assessment, which may include a physical exam to test whether your symptoms are related to a brain or nerve disorder.

A typical physical exam will look at your:

• Behavioral or mental status
• Head and neck
• Cranial nerves
• Motor function
• reflexes
• Coordination and gait
• Sensory function

As needed, your neurologist will recommend further testing, such as a CT scan or MRI scan, to confirm a diagnosis.
