Electrocenphalogram (EEG) Testing

An electroencephalogram (EEG) is a painless test that detects electrical activity in your brain using small, flat metal discs (electrodes) attached to your scalp and connected by wires to a computer. Your brain cells communicate via electrical impulses and are active all the time, even when you're asleep. The computer records the electrical activity in your brain, which a neurologist will view to determine if there are any changes to the normal brain activity. This study is used to detect abnormalities.

Common indications for an EEG are:

  • Diagnose epilepsy
  • Confirm seizures (classify type and localize)
  • Loss of/or changes in consciousness
  • Dementia
  • Headaches/Migraines
