Purpose: The cerebral function in children with epilepsy (CWE) ranges from normal to severe encephalopathy. However, the little is known about the neurophysiologic changes in CWE with normal intellectual function. Our question was that if there was any difference in event related electroencephalographic changes in such patients. As the alpha oscillation is emerging as the key rhythm in attention controls, we investigated the 10 Hz−event related synchronization (ERS) and phase locking characteristics in normal intelligent CWE. Methods: The subjects were 11 CWE patients (M : F = 3 : 8) (9.7 ± 2.1 years) with infrequent generalized or partial seizure and age matched 11 controls (M : F = 4 : 7) (9.7 ± 2.9 years). We used auditory oddball paradigm with 500 Hz standard (SS) and 1,000 Hz deviant stimuli (DS). ERS and phase locking index ( PLI) values during first 400 ms after stimuli were evaluated by the 10 Hz complex Morlet wavelet components. The peaks and latencies of ERS and PLI were analyzed. Also, the neuropsychological test results in both groups were analyzed. Results: The full scale IQ in both groups were not significantly different (CWE vs controls = 101.0 ± 11.4 vs 109.5 ± 10.7, P = 0.133). ERS peak to DS was significantly lower in PWE than in controls at Fz (14.0 ± 11.5 % vs 20.6 ± 12.6 %, P = 0.030), F8 (14.3 ± 8.3 % vs 19.6 ± 12.5 %, P = 0.049), and T7 (10.7 % ± 11.5 % vs 20.7 ± 11.8 %, P = 0.001). The latency to ERS peak to DS was significantly shorter in PWE than in controls at F7 (164.6 ± 72.8 ms vs 219.6 ± 86.3 ms, P = 0.006), and Cz (187.9 ± 87.7 ms vs 247.3 ± 87.0 ms, P = 0.008). PLI peak to DS was significantly lower in PWE at F7 (0.31 ± 0.08 vs 0.41 ± 0.12, P = 0.000), Fz (0.35 ± 0.08 vs 0.40 ± 0.09, P = 0.027), T7 (0.34 ± 0.07 vs 0.44 ± 0.11, P = 0.000), and T8 (0.32 ± 0.10 vs 0.40 ± 0.11, P = 0.007). The results of latencies to PLI peaks to DS were inconsistent. Conclusions: Our results showed the altered ERS and ITC responses to DS in fronto−temporal cortex in normal intelligent CWE. It suggests the subclinical impairment of the cortical auditory processing in these patients.
