What to expect during an EEG test

An electroencephalogram (EEG) is a safe, noninvasive test used to diagnose many brain disorders. Our brains send out small electrical impulses, and EEGs monitor this activity and translate it into a visual image. This image gives us a wealth of information about brain health.

EEGs are used to diagnose neurological conditions such as:

  • Alzheimer’s disease
  • Brain tumors
  • Concussions and other traumatic head injuries
  • Dementia
  • Epilepsy and other seizure disorders
  • Encephalopathy (abnormal brain function)
  • Narcolepsy and other sleep disorders

An EEG typically takes between 20 to 60 minutes to complete, although some can take up to three hours. To conduct this test, a technician will place several small metal discs (electrodes) on the scalp, then connect the discs to an instrument that monitors and records brain waves. While relaxing with your eyes closed for most of the test, we may ask you to complete simple tasks such as looking at a picture or reading a few sentences aloud while the EEG is being administered.

EEG testing is just one of the advanced diagnostic services offered by the Department of Neurology at Florida Medical Clinic. We offer a comprehensive range of services, including EMG and EEG testing, nerve conduction studies, and visual evoked potentials. All tests are conducted and interpreted by our team of highly experienced neurologists.
