EEG

What is EEG?

Electroencephalography (EEG) is a non-invasive medical technology used to record the electrical activity of the brain. By placing electrodes on the scalp, EEG measures the brain’s electrical impulses, providing crucial insights into its functioning. EEG is commonly used to diagnose neurological conditions such as epilepsy, sleep disorders, and brain injuries, and it can also be used to monitor brain activity during surgeries or in intensive care units.

How is EEG Performed?

During an EEG procedure, small electrodes are attached to the patient’s scalp using conductive gel. These electrodes detect the brain’s electrical activity, which is then amplified and recorded as a series of waveforms. The entire process is painless and usually takes between 30 minutes to an hour, depending on the test’s complexity. Patients may be asked to perform certain tasks, close their eyes, or even sleep during the procedure to gather comprehensive data.
