What Does This Mean?

I was looking at an old EEG report and it says this
(Quote) The technologist noted the patient to be drowsy. The resting record consists of mainly drowsy and sleep states in the form of mixed frequency background compromising of beta and delta waves. Stage 1 and 2 of sleep were noted with its appropriate features. Infrequent focal independent beta and delta were noted to arise from the left temporal head region. Hyproventilation produced mild background slowing where generalized high voltage delta activity is noted that is suspicious for epilepticform activity. Photic stimulation useing a stepwise increase in flash frequencies results in an edequate driving response in addition to inducing myogenic response.
(End of quote)
Can anyone tell me what this means or an idea?

The part of the EEG report that might suggest seizure activity is this:

"Infrequent focal independent beta and delta were noted to arise from the left temporal head region. Hyperventilation produced mild background slowing where generalized high voltage delta activity is noted that is suspicious for epileptiform activity."

Beta and Delta brainwaves are normal when drowsy, but usually symmetrical (i.e. appear on both sides of the brain at the time). It sounds like during your EEG they appeared a few times in the left temporal area only, which might suggest a lesion of some sort in that area. "Slowing" and "Generalized high voltage delta activity" can suggest a potential for seizure activity.

These results would need to analyzed and interpreted by the neurologist to determine if they indicate epilepsy. Some factors the neurologist would take into account would be the duration of any abnormal waves and the context -- whether you are awake or asleep at the time, etc.
