What is a 72 hour EEG used for?
For people experiencing neurological concerns, such as seizures, a 72-hour EEG provides valuable insights to help doctors diagnose or rule out conditions. An EEG, short for electroencephalogram, records the brain’s electrical signals using small electrodes attached to the scalp.
What percentage of EEGS are normal?
More than 10% of normal people may have non-specific EEG abnormalities and approximately 1% may have ‘epileptiform paroxysmal activity’ without seizures. The prevalence of these abnormalities is higher in children, with 2–4% having functional spike discharges.
Can EEG show brain damage?
An EEG can find changes in brain activity that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder. An EEG might also be helpful for diagnosing or treating: Brain tumors. Brain damage from head injury.
What can a 72-hour EEG tell you?
For people experiencing neurological concerns, such as seizures, a 72-hour EEG provides valuable insights to help doctors diagnose or rule out conditions. An EEG, short for electroencephalogram, records the brain’s electrical signals using small electrodes attached to the scalp.
What is an EEG test?
An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.
How does the technician measure my head for an EEG?
The technician will measure your head and mark where to place the electrodes. These spots are scrubbed with a special cream that helps the electrodes get a high-quality reading.
How long does an EEG take to perform?
Once the electrodes are in place, an EEG typically takes up to 60 minutes. Testing for certain conditions require you to sleep during the test. In that case, the test can be longer. You relax in a comfortable position with your eyes closed during the test.
