Modern medical science for tracking electrical waves from billions of brain neurons and diagnosing neurological conditions.
An EEG, or Electroencephalogram, is a simple and painless test. Neurons in our brain generate tiny electrical signals to communicate with each other. These signals are recorded by placing small metal discs (electrodes) on the scalp.
These signals are displayed as continuous wave patterns on a computer screen. Commonly known as “brain waves,” these patterns help neurologists analyze any electrical abnormalities in the brain.
An EEG is the most critical test for diagnosing epilepsy and determining the exact type and brain origin of sudden seizures.
It is used to analyze the underlying causes of sleep disorders such as insomnia, sleepwalking (somnambulism), or sleep apnea (breathing difficulty during sleep).
An EEG helps evaluate electrical brain abnormalities caused by sudden confusion (encephalopathy), severe memory loss (dementia), stroke, or traumatic brain injury.
Wash your hair thoroughly with shampoo and dry it on the day of or the evening before the test. Do not use oil, hair gel, spray, or conditioner, as these interfere with electrode signals.
Avoid tea, coffee, chocolate, cola, or energy drinks for at least 8 hours prior to the test. Caffeine can temporarily alter natural brain wave patterns and cause inaccurate readings.
Sometimes an EEG needs to be performed while asleep. In such cases, your doctor may advise you to sleep less or stay awake the night before so you can fall asleep naturally during the procedure.
If you routinely take anti-seizure or nerve medications, confirm with your doctor or technologist beforehand whether to take them on the day of the test.

How Do Brain Waves Work?
Our brain never stops working. Whether we are awake, thinking, or sleeping, brain cells continuously generate their own natural electrical signals or “brain waves.”
100% Safe and Painless Examination: An EEG test does not pass any electrical current through your body. It is a completely safe, side-effect-free procedure that only measures your brain’s natural electrical frequency to help neurologists evaluate your overall nerve health.
An EEG is a safe, painless procedure that sends no electricity into the body; it simply measures your brain’s natural electrical activity. Follow your doctor’s guidance without hesitation or fear.
