EEG – Electroencephalography

What is an EEG(Electroencephalography)

Electroencephalography (EEG) is the recording of electrical activity of brain cells along the scalp. EEG measures electrical fluctuations resulting from current flows within the neurons of the brain. In clinical contexts, EEG refers to the recording of the brain’s spontaneous electrical activity over a short period of time, usually 20–40 minutes, as recorded from multiple electrodes placed on the scalp.

In neurology, the main diagnostic application of EEG is in the case of epilepsy, as epileptic activity can create clear abnormalities on a standard EEG study. In Intensive Care clinical use of EEG is in the diagnosis of coma, encephalopathies, Traumatic Brain Injury (TBI) and Brain Death.

How Does It Work?

Small caps are attached to your loved ones scalp and these pick up signals of electrical energy from the brain. Specially trained doctors(usually neurologists) and nurses can interpret these waveforms. Diseases such as epilepsy (Seizures or fits), and severe brain injury (Traumatic Brain Injury (TBI)) from lack of oxygen may be measured using an EEG machine. A single recording or a continuous recording of brain waves may be done. This measurement does not hurt your loved one. The EEG machine may either be a separate piece of equipment or available in the bedside monitor.

Are There Any Complications?

All Intensive Care interventions and procedures carry a degree of potential risk even when performed by skilled and experienced staff. Please discuss these issues with the medical and nursing staff who are caring for your loved one.

Any Questions?

Of course, if you have any questions or concerns, please discuss them with the ICU nurses and doctors.
