Interpretation of Electroencephalograms (EEG)

An electroencephalogram, or EEG, is a test used to evaluate the electrical activity in the brain. Electrodes placed on the scalp are used to detect tiny electrical charges that result from the activity of brain cells.
EEGs are used to evaluate several types of brain disorders including , but not limited to: seizures caused by epilepsy, lesions resulting from tumors or stroke, and Alzheimer’s. There may be other reasons for your doctor to recommend an EEG.

What to Expect for an EEG
Our EEGs are performed in our office. An EEG records the brain’s continuous electrical activity by means of electrodes attached to the scalp. Feel free to wash your hair with shampoo and conditioner, but do not put oil or any styling product in your hair. This is a non-painful study and carries no risk. You may be instructed to remain sleep deprived prior to the study. Typically, this means four (4) hours or less of sleep the night before the study, with no naps prior to the study. During the study, you may be asked to hyperventilate and you may be exposed to a flashing light. Avoid caffeine and bring a list of your medications with you to provide to the technician performing the EEG. You should take medications as prescribed. A neurologist will interpret the study and prepare a report based on the findings of the study.
