Age, EEG and neuroimaging of patients with seizures ( IED= interictal discharges).

PatientsAgeEEG background &IEDIctal dischargesNeuroimaging
1NeonateHypsarrhythmia with multifocal IEDelectrographic seizures seen over the left frontocentralNormal MRI brain
28 MonthsNormal for age background with multifocal IEDGeneralized electrodecremental ( epileptic spasm )Normal MRI brain
3NeonateNormal for age background with no IEDAn electrographic event 9Hz right temporal T4 ( Figure 2)Normal brain US
46 MonthsHypsarrhythmia with multifocal IEDGeneralized electrodecremental (epileptic spasm )MRI brain: bilateral symmetrical T2 hyperintensity involving the globuspallidi bilaterally and the lateral thalamic nuclei
510 MonthsGeneralized slow background with Left temporal IEDThree electrographic seizures were recorded all focal arising from left hemisphereMRI brain: Diffuse cerebral atrophy
63 MonthsGeneralized voltage attenuation of background with no IEDGeneralized electrodecremental (epileptic spasm )MRI brain: Interval progression of the diffuse cerebral atrophy.
77 MonthsHypsarrhythmia with Multifocal IEDGeneralized electrodecremental (epileptic spasm )MRI brain: bilateral symmetrical T2 hyperintensity involving the globus pallidi bilaterally and the lateral thalamic nuclei .
84 MonthsNormal for age background with Left temporal IEDIctal discharges at left temporal region associated with clinical bradycardiaNormal MRI brain
92 MonthsNormal for age background with Bilateral temporal IEDBuild up sharp waves on left temporal region mostly electrographic seizureCT head : brain atrophy and craniosynostosis
10NeonateNormal for age background with multifocal IEDGeneralized electrodecremental (epileptic spasm)Normal brain US
