What is the purpose of the Electroencephalography (EEG) test?
An electroencephalogram (EEG) is a test used to find problems related to electrical activity of the brain. An EEG tracks and records brain wave patterns. Small metal discs with thin wires (electrodes) are placed on the scalp, and then send signals to a computer to record the results.
What is the test about?
Electroencephalography (EEG) is a neurophysiology test which analyses the electrical activity generated by the brain. Special sensors (metal disc electrodes) are attached onto the head and hooked by wires to a computer. Common reasons for referral include:
Electroencephalography (EEG) can also be performed as part of the investigations of some patients with syncope. Syncope, also known as fainting in medical terms, is defined as a transient loss of consciousness and postural tone, characterized by rapid onset, short duration and spontaneous recovery due to low blood flow to the brain usually because of low blood pressure.
