Video Monitoring Recording

Date of Procedure: Date started: 01/12/2009
Date completed: 01/13/2009

Procedure: 23-hour Video Monitor Recording

Clinical History: This is a 3 yr old child with a history of bilateral perisylvian syndrome, infantile spasms, now having startle episodes again.

Medications: None

Recording Date: The scalp electrodes were applied according to the International 10/20 system of electrode placement. Zygomatic electrodes were also used. The recording was made on the Nihon Kohden digital EEG system.

Digital EEG Analysis: The automatic seizure-spike detection programs were applied.

Findings: Background activity: The background activity during the awake state consisted of posterior dominant theta activity at 5-6 Hz which was bilaterally symmetrical.

During sleep, sleep spindles were seen bilaterally.

Interictal Findings: Interictally there was presence of right temporal-central as well as right temporal-central spike and wave activity seen.

Clinical Events: There were spasms captured. These spasms showed minimal EEG correlation or sometimes the EEG correlation was obscured by EMG activity. Some spasms showed diffuse spike wave activity followed by attenuation. We would not localize the seizure onset..

Impression: This is an abnormal video EEG monitoring. The background activity is slow for age which suggests diffuse neuronal dysfunction. There is present of multi-focal spike and wave activity as well as multiple spasms captured during the recording.
