Electroencephalogram (EEG) is a noninvasive test that is used to detect electrical activity in the brain. This process is done by using small, flat electrodes that attach to the scalp. Cells within the brain communicate with one another vial electrical pulses within the brain. Electrical impulses such as this occur no matter whether an individual is awake or asleep. Through the use of an EEG it allows for medical providers to assess the brain activity within the human body.
Epileptologists rely heavily on EEG’s for diagnostic testing for Epilepsy patients.
Not only do EEG’s assist in helping diagnose Epilepsy patients, they also assist in diagnosing other brain disorders. An EEG can determine changes in brain activity that is useful for diagnosing brain disorders. Some of the disorders that can be tested include but are not limited to the following:
- Brain activity during a coma
- Brain tumors
- Certain forms of brain dysfunction
- Epilepsy or other seizure disorder
- Brain/Head injury
- Inflammation of the brain (encephalitis)
- Sleep disorders
EEG’s are designed to be safe and painless and allow for physicians to read and understand the brain in a variety of states whether a patient is asleep, in a coma, or even experiencing a seizure.
