Electroencephalogram (EEG)
 An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. Special sensors (electrodes) are attached to your head and hooked by wires to a computer. The computer records your brain's electrical activity on the screen or on paper as wavy lines. Certain conditions, such as seizures, can be seen by the changes in the normal pattern of the brain's electrical activity.
 
Why It Is Done
 An electroencephalogram (EEG) may be done to:
  • Diagnose epilepsyand see what type of seizures are occurring. EEG is the most useful and important test in confirming a diagnosis of epilepsy.
  • Check for problems with loss of consciousness or dementia.
  • Help find out a person's chance of recovery after a change in consciousness.
  • Study sleep disorders, such as narcolepsy.
  • Help find out if a person has a physical problem (problems in the brain, spinal cord, or nervous system) or a mental health problem

What should I do to prepare for an Electroencephalogram (EEG)?

 

  • You may only have 4 hours or less of sleep the night prior to the EEG. Stay awake for several hours before the test. Limit caffeine for 12 hours in advance of test. (decaf is ok). You may eat normally.
  • Wash your hair the night before the test is done. Do not use hair products such as grease, gel, mousse, hairspray, oil, dandruff shampoo or scalp treatment. 

             *NOTE: your test will be rescheduled if there is any sign of lice.

  • Take medications as usual unless your Doctor tells you otherwise.
  • We prefer no other family members present with the patient during the test, unless necessary to provide medical information.
  • You may want to bring a scarf or hat as your hair will be slightly damp and messy after the test. 
You must be on time for this test or we will have to reschedule.
Any instruction not followed may result in your test being rescheduled.
 *Any questions regarding these instructions should be directed to the EEG Department.
 
Videonystagmography (VNG)
VNG is a test of your balance system. An extensive evaluation is required at times to determine the cause of dizziness or unsteadiness. The tests necessary to diagnose your problem have been determined by our doctor at the time of examination, and may include detailed hearing and balance tests. The object of this evaluation is to be certain that there is no serious disease, and to try to pinpoint the exact site of the problem. This lays the ground work for effective medical or surgical treatment by your doctor.

Who needs a VNG?

  • Anyone who has a history of falling
  • Anyone who complains of dizziness
  • Anyone expressing a fear of falling
  • Anyone 50 years of age or older who; 
    Is having difficulty adjusting to wearing new glasses, especially bifocals. Has deteriorating hearing or previously undiagnosed hearing loss which requires treatment or hearing device.
BOTOX® Therapy
BOTOX® treatment for Cervical Dystonia (CD)
CD is a condition that affects muscles in the neck. If you have CD, those muscles may tighten or spasm without your control. This can force your head and neck into movements or positions that are painful and awkward. It often makes it difficult to do simple things such as dressing, shaving, housework, driving a car, or using a computer. Treatment can manage symptoms and may help you return to activities you enjoyed before your symptoms started.
Many people with CD get relief from BOTOX® injections. BOTOX® works directly on the muscles that spasm. After a BOTOX® treatment, many patients get relief from muscle spasms for up to 3 months. BOTOX® also helps reduce neck pain in patients with CD. Pain relief may happen first, before muscles become significantly relaxed.

BOTOX® treatment for blepharospasm (eyelid spasms)
Blepharospasm can also be treated with BOTOX®. This condition causes spasms in and around the eyelids. This results in frequent blinking and closing of the eyes that you can’t control. Because of these symptoms, it can be hard to see. Treatment with BOTOX® can reduce muscle spasms. This reduces blinking, which may help restore the ability to see.

 Lumbar Puncture (also called a spinal tap)
A lumbar puncture is done to evaluate the fluid (cerebrospinal fluid, or CSF) surrounding the brain and spinal cord.  It is done to evaluate symptoms possibly caused by an infection (such as meningitis), inflammation, cancer, or bleeding in the area around the brain or spinal cord (such as subarachnoid hemorrhage).  It is used to diagnose certain diseases of the brain and spinal cord, such as multiple sclerosis or Guillain-Barre syndrome.   It also measures the pressure of cerebrospinal fluid (CSF) in the space surrounding the spinal cord.  
Tell your doctor all medications you are taking (bring a list).
Have a driver with you.
Tell your doctor if you are on any blood thinners as these must be stopped 5-7 days prior to the lumbar puncture.  
Tell your doctor if you are, or might be, pregnant.   
Evoked Potential Tests
Evoked responses indicate the brain’s response to specific stimuli.  Three kinds of evoked potential procedures are used by neurologists:
  • Visual evoked potentials test the visual pathways between the retina (eye) and the brain by presenting alternating checkerboard patterns.
  • Auditory evoked potentials test the auditory pathways between the ear and the brain by presenting auditory clicks.
  • Somatosensory evoked potentials test the pathways between the peripheral nerves through the spine to the brain by stimulating nerves with small electrical pulses.
There are no specific instructions for this type of testing.
