Localisation of the electroencephalographic changes in children with viral meningitis

Background: Viral meningitis is inflammatory infection of central nervous system that is rarely serious and commonly doesn't affect child's neurological development. EEG is often performed in viral meningitis for distinguishing it from meningoencephalitis. Aim: The aim of this study was to investigate the localisation and the freguency of EEG changes in viral meningitis. Method: 58 children with the mean age 9-years was hospitalized in General County Hospital in Požega between june and december 2009 due to enteroviral meningitis. There were 16 girls (28%) and 42 boys (72%). Diagnose was confirmed by liqour examination and PCR. EEG was performed in acute phase, and later for follow- up. All of children were non-epileptic patients. Results: 39 (67%) recordings in acute phase were reported as normal. EEG changes were recorded in 19 (33%) patients. 8/19 (43%) abnormal recordings had diffuse abnormalities and 11/19 (57%) had focal abnormalities. 3 recordings had unilateral frontotemporal spikes, 1 had unilateral temporal spikes. 2 recordings had unilateral and 5 bilateral occipital slow sharp waves. After one year follow-up, 12/19 (63%) recordings were normalised and 4 /19(21%) of them still had focal and diffuse abnormalities. 3/19 (16%) patient had been lost in follow-up. Conclusion: EEG recordings were mostly normal. The most frequent abnormal recordings were unilateral and bilateral occipital slow sharp waves. 63% of abnormal recording normalised during the first year follow-up.
