ELECTROENCEPHALOGRAM (EEG)

Electroencephalography is a widely used non-invasive method to sense and measure electrical activity of the brain. This is done by placing electrodes on the scalp, which measures voltage fluctuations across the neurons. The graph upon which these activities are plotted is known as Electroencephalogram(EEG).

A normal EEG indicates the typical pattern of brain wave activity of an individual. While an abnormal pattern may indicate one or more of the following:

1. Memory impairment in dementia or Alzheimer’s syndrome.
2. Infections, such as encephalitis or local neural inflammation.
3. Head injury, brain tumor or brain abscess.
4. Neural epilepsy, Sleep disorders or even brain death.

Since the brain is the ‘’processor and controller" of all voluntary and higher order actions, reflexes and judgments, it can prove fatal to neglect even the slightest symptoms of acute pain in the brain, or any similar neural disturbances.

Routine EEG: Here, the patient is asked to relax and open or close eyes at certain intervals. In most recordings, he/ she may be asked to breathe deeply for about 3 minutes. Overall, the test lasts for about 20-40 minutes.

Sleep EEG: As the name suggests this test is carried out when the patient is asleep. It is generally conducted for sleep disorders, or if no confirmatory evidence is established in the routine EEG procedure.

Ambulatory EEG: When EEG is conducted throughout the day and night for one or more days, then it is called ambulatory EEG. The patient is equipped with an EEG recorder clipped with his/ her clothing, which does its prescribed duty for the specific time period.

EEG is a safe procedure which is seamlessly carried out by our certified personnel. There are no special instructions for the post-operative care. However, you will need to wash your hair to remove traces of gel and other fluids.
