SAMPLE EEG - (ELECTROENCEPHALOGRAM)

PROCEDURE:
A 16-channel electroencephalogram is performed with the patient awake, drowsy, and in stage 2 sleep pattern.

During wakefulness, the posterior background is comprised predominately of 9 Hertz alpha activity, which is well modulated, symmetric, and responsive to eye opening. The anterior background contains 15-20 Hertz low voltage beta activity.

With drowsiness there is attenuation of the posterior alpha rhythms, and 5-7 Hertz bitemporal and sensual beta rhythms are noted.

With early stage 2 sleep, there is 3-4 Hertz slowing of the record with occasional midline vertex waves and synchronous sleep spindle formation.

Three minutes of hyperventilation does not significantly alter the record.

Photic stimulation does not significantly alter the record.

No lateralizing asymmetries or epileptiform discharges are noted.

IMPRESSION:
This is an unremarkable awake, drowsy and stage 2 sleep electroencephalogram.

No evidence of ictal discharges or lateralizing asymmetries are present.

BRIEF NEURO SAMPLE PHYSICAL EXAM

The patient was awake and alert and oriented x3. Judgment, memory, and language were intact. Cranial nerve examination showed bilateral proptosis, otherwise noncontributory. Motor examination revealed no evidence of focal deficits. Tone was normal in upper and the lower extremities. The muscle strength was 4/4 symmetrical. Sensory was intact to light touch, pinprick, vibration, and positional sense. No evidence of ataxis or dysmetria. The patient was ambulatory.
