Routine EEG

  • An electroencephalogram (EEG) is a recording of brain activity.
  • During this painless test, small sensors are attached to the scalp to pick up
    the electrical signals produced by the brain. These signals are recorded by a
    machine and are looked at by your doctor.
  • The procedure usually takes between 30-40 minutes.

Long-term EEG Monitoring

  • Long-term electroencephalographic (EEG) monitoring is the process of
    recording an EEG for a prolonged period in order to document epileptic
    seizures or other episodic disturbances of neurologic function.
  • In adults, long-term EEG monitoring typically involves one of three procedures
    which include long-term video-EEG monitoring, sleep-deprived EEG monitoring,
    and 24-hour ambulatory monitoring. Long-term video-EEG monitoring typically lasts from a
    few hours to several days.

EMG / NCS

  • This is a specialized electrical test of your muscles and nerves.
  • The test consists of two parts; first NCV (Nerve Conduction Study) is
    performed by the technologist using a small electrical impulse to stimulate
    the nerve and record the response from nerve/ muscle.
  • The second part is called EMG or ectromyography, which consists of a
    needle exam. (very small, thin needle inserted into your muscles to record
    electrical activity)
  • The EMG part is performed in conjunction with NCV and is not always
    needed.
  • Your physician’s request for the type of test and your exam determines
    the need and extent of the testing.
