AGUILAR FABRE, Liane et al. Spectral analysis of the electroencephalogram in patients with rolandic epilepsy. Rev haban cienc méd [online]. 2012, vol.11, n.1, pp. 45-50. ISSN 1729-519X.
Objective: To describe abnormalities of the background activity by quantitative analysis in patients with Rolandic Epilepsy. Methods: Visual (29 patients) and quantitative EEG (QEEG) (26 patients) analyses were done. Absolute and Relative Power values obtained in the patients were compared with those from a normative database (Z-Maps). Results: Q-EEG results showed a significative changes in a 73,08 % of the patients: 73,68 % in slow frequency and 26,31 % in rapid frequency. A focal significative increase in slow frequency in centro-temporal and/or centro-parietal regions was observed in 64,28 %, in the same regions and extratemporal regions in 21,43 % and only slow activity extratemporal in 14,28 % of the patients. Conclusions: Significative variations in background activity in patients with Rolandic Epilepsy, suggests a possible relation with the presence of interictal epileptiform discharges or a certain age-related functional immaturity.
