Some patients may know what an EEG is used for, but even fewer know the extent of its neurodiagnostic capabilities. An EEG is a diagnostic tool that provides information which, along with additional tests, assists the doctor form the diagnosis for the patient.
An EEG may show an area of the brain that reveals unexpected activity which would allow the doctor to order additional tests to investigate the cause. EEG is one of many tests performed to provide information to the doctor to assist in forming a diagnosis.
Today we hope to answer questions that patients often wonder about by looking at their top 3 concerns regarding the brain and EEG:
Can an EEG show brain damage?
Can an EEG detect a brain tumor?
Can an EEG detect brain death?
To shed some light on how powerful a neurodiagnostic tool EEG really is, let’s explore its effectiveness. Keep in mind that the EEG by itself would not conclusively determine any of these diagnoses.
