Focal EEG abnormality
 

I recently had an EEG and was told I had "significant slowing" in my temporal lobe. The most common type would be PDA, or Polymorphic Delta Activity.
An MRI did show "small areas of periventricular white matter T2 prolongations.
I became symptomatic following a nasty temporal lobe seizure when I was a teen. (altered states, organic brain syndrome). But, the MRI analysis is that my MRI is normal/non-specific.
Anyone have any knowledge of PDA, and how it might be treated?
