I had the surgical procedure done in December 1989. 12 different rods where implanted. This was done at Alleghany General Hospital in Pittsburgh. The regular EEG's done showed activity near left temporal lobe. Two weeks of study produced no seizures. I went home on the 23rd. Christmas Eve, I had a seizure. The test showed no other areas of the brain that was abnormal. The 2-week study in the hospital was over $100,000. It was agreed to with the hospital that they would accept what my insurance would pay. Otherwise, I wouldn't have had it done. My hair came back, but not nearly as thick as it was prior to the procedure. It slowly thinned out and I'm practically bald in the area.
