    Abnormal EEG

    My husband had a seizure 5 months ago in his sleep and then another one last night in his sleep. . He is 51 years old and had no history of seizures or epilepsy.. He was battling an ear infection at the same time so it was insinuated that that may have been the cause. The CT Scan done at the hospital was normal 5 months ago. They did a 24 Hour EEG that we just received the results to. We will be seeing the doctor in about a week but was wondering if anyone knows what these results mean in the meantime.

    PATIENT HISTORY: 51-year-old male with first GTC seizure out of sleep

    LEVEL OF ALERTNESS: awake and asleep


    TECHNICAL ASPECTS: This EEG study was done with scalp electrodes positioned according to the 10-20 International system of electrode placement. Electrical activity was acquired at a sampling rate of 500Hz and reviewed with a high frequency filter of 70Hz and a low frequency filter of 1Hz. EEG data were recorded continuously and digitally stored.

    Posterior background activity: The posterior dominant rhythm was present and consisted of a continuous, irregular 9-10 Hz, moderate voltage rhythm distributed symmetrically in the posterior head regions that was reactive to eye opening and closure.

    Beta: There is 15 to 18 Hz, 2-3 uV beta activity with irregular morphology distributed symmetrically and diffusely.

    Slowing: Intermittent, irregular, regional 5-7 Hz slow wave activity were present over the right frontocentral region

    Interictal epileptiform activity: none

    Ictal Activity: none

    OTHER EVENTS: none

    Stage 1 and 2 sleep architecture was seen, including vertex waves, sleep spindles, and K complexes.

    Hyperventilation was not performed.

    Photic stimulation was not performed.

    This study is abnormal due to

    Intermittent, irregular, regional slow wave activity were present over the right frontocentral region

    These findings are consistent with focal neuronal dysfunction in the right frontocentral region.

    No seizures or epileptiform discharges were seen throughout the recording.
