My symptoms: poor memory, hard time concentrating, left side of face sometimes feels tingly and mouth droops for 5 seconds, tired, irritated, headache?

EEG ?: Positive focal symptoms of a fleeting nature (parasthesias in the left side of the face) associated at times with facial paralysis. On Welbutrin (lowers the seizure threshold) DDX includes migraine and focal seizure. TIA not likely as symptoms are recurrent and limited to a relativity small area of cortex (lower right parietal lobe just above non dominant right temporal lobe.)
