Best Neurologist on Long IslandElectroencephalogram (EEG) scans are used to analyze and detect conditions associated with the brain’s electrical activity. EEG’s assist in diagnosing brain disorders such as epilepsy, dementia, and even sleep disorders. The EEG process itself is painless, safe, and shouldn’t pose any threat of injury to the patient. Small metal electrodes are connected to a computer and then fastened to the patient’s head, and for thirty to sixty minutes, the electrodes record the electrical impulses of the brain.

Conditions that are Diagnosed with an EEG:

For a better understanding of the issues that EEG scans to test for, below are some of the common conditions and their symptoms:

  • Epilepsy – A common neurological disorder defined by unprovoked and unrelenting seizures or sudden rushes of electrical activity in the brain. Degrees of severity with seizures range from mild to strong, lasting anywhere from a few seconds to a couple of minutes. Seizures themselves are the primary symptom of epilepsy, but seizures can be caused by other stimulants such as head trauma, low blood sugar, or a high fever.
  • Encephalitis – A rare condition characterized by inflammation of the brain tissue caused by a viral infection. Viruses that are known to have caused encephalitis include; Epstein-Barr, mumps, and HIV. Mild symptoms range from headaches, vomiting, and lethargic behavior, while severe symptoms include hallucinations, sensitivity to light, or even a coma.
  • Sleep Disorders – Typically common today, sleep is often interrupted by stress from every-day activities. Those dealing with a sleep disorder may experience difficulty falling or staying asleep, trouble concentrating, and daytime tiredness. In some cases, sleep disorders may serve as a symptom of mental illness, and when left untreated, sleep disorders can lead to other negative health consequences.
  • Dementia – Normally found in older patients, dementia is a neurodegenerative disorder that impairs a person’s memory, behavior, thinking, judgment, or language. Symptoms of dementia include a confused sense of direction, not coping well with change, being repetitive, and short-term memory loss.

Preparing For An EEG:

As previously mentioned, an EEG scan is safe and will have no ill-effects on a patient. To get the most from this test, however, preparations need to be made on your end. First, be sure to wash your hair the night before an EEG. Also, refrain from using any products such as sprays or gels the night before and day of the scan. Avoiding eating or drinking anything containing caffeine for up to eight hours before the test is necessary. It would also be beneficial to give our staff a list of any medications you are currently taking so you can be instructed to stop doing so if deemed necessary. Once the test has been completed, you can go back to your normal routine.
