Does magnetoencephalography add to scalp video-EEG as a diagnostic tool in epilepsy surgery?

mation of the expected incidence. A wide scatter of incidence rates was noted in the below 40 age group in the studies considered by the author, resulting in inability to fit regression curves to incidence data. This was one of the author’s reasons for using mortality data rather than incidence data. Consequently, in my opinion, the method had the appearance of greater precision than the reality it was modeling. I would like to pay tribute to the bravery and courage of all veterans and all patients with ALS.
