OBJECTIVE: To investigate determining factors of the ictal scalp EEG pattern at @entity410 onset and its predictive value for postsurgical outcome in @entity1 with unilateral MTLE due to @entity131 (MTLE-HS). METHODS: Review of consecutive @entity1 with chronic MTLE-HS undergoing presurgical video-EEG telemetry. Exclusion criteria were additional epileptogenic lesions or @entity410 generators or compromised EEG traces at @entity410 -onset. Mixed linear or logistic regression models were used. RESULTS: Inclusion of 63 @entity1 with 219 @entity410 with a favorable outcome (no @entity410 or auras only) in 43 @entity1 at last follow-up. @entity410 ( @entity410 ) had a frequency of 4.7  1.5/s (range 1-8/s), mostly localized in the anterior temporal region. Postsurgical @entity410 outcome was not associated with any clinical or electrophysiological feature. @entity410 in the delta-band was more often observed with @entity302 (p=0.002). CONCLUSIONS: @entity410 on scalp EEG gets faster with increasing @entity302 duration, possibly via time-dependent alterations of epileptogenic networks. Neither the frequency of @entity410 nor other EEG-features appeared to predict postsurgical @entity410 outcome. SIGNIFICANCE: The results challenge the view that if @entity1 with apparent MTLE display @entity410 in the delta-band, @entity410 -onset in neocortical structures rather than in temporo-mesial tissue should be considered and further investigations should be prompted.
