Sample Report Electroencephalogram
Clinical History: The patient is a 76-year-old female who presents with spells consisting of tingling sensation and taste dysfunction. She also had a previous stroke. She is on Synthroid, Coumadin, Zoloft, and Cardizem.
Technical Description: This is a 21-channel recording with the patient in the awake and drowsy states. Eighteen channels were used for EEG, together with two channels of EOG and one channel of EKG. Referential and bipolar montages were used with the Standard 10-20 Electrode System. In addition, T1 and T2 electrodes were utilized. The patient was not sedated further.
Report: During wakefulness, the background activity consisted of a posteriorly dominant, relatively irregular 9 hertz alpha activity with amplitudes of up to 30 microvolts. This was reactive to eye opening and was intermixed with moderate amounts of anteriorly dominant, lower amplitude, faster frequencies in the beta band. Hyperventilation was not performed due to the patient's medical condition. Photic stimulation elicited some mild driving response symmetrically. The sleep study only showed some drowsy periods with alpha dropout. No definite spindle activity was seen. There was some fluctuating asymmetry and frequency, but no definitive focal slowing.
Impression: This electroencephalogram is within normal limits. No definite epileptiform or lateralizing activity was seen. Clinical correlation is suggested.
