EEG (Electroencephalogram) in Medavakkam, Chennai
EEG test in Medavakkam, Chennai to record brain activity for seizures, fainting and neurological symptoms. Painless and safe.
An EEG (electroencephalogram) records the electrical activity of the brain using small electrodes placed on the scalp. It helps doctors evaluate seizures, epilepsy, fainting spells and other neurological symptoms. EEG is available at Venkateswara Diagnostic Centre, Medavakkam, Chennai.
What is an EEG?
Brain cells communicate through tiny electrical signals. An EEG picks these up through the scalp and shows them as wave patterns that a neurologist interprets.
The test is painless — nothing is sent into the brain. You may be asked to breathe deeply or look at a flashing light, as these can bring out certain patterns.
When do doctors recommend an EEG?
