Age, EEG and neuroimaging of patients with seizures ( IED= interictal discharges).
| Patients | Age | EEG background &IED | Ictal discharges | Neuroimaging |
|---|---|---|---|---|
| 1 | Neonate | Hypsarrhythmia with multifocal IED | electrographic seizures seen over the left frontocentral | Normal MRI brain |
| 2 | 8 Months | Normal for age background with multifocal IED | Generalized electrodecremental ( epileptic spasm ) | Normal MRI brain |
| 3 | Neonate | Normal for age background with no IED | An electrographic event 9Hz right temporal T4 ( Figure 2) | Normal brain US |
| 4 | 6 Months | Hypsarrhythmia with multifocal IED | Generalized electrodecremental (epileptic spasm ) | MRI brain: bilateral symmetrical T2 hyperintensity involving the globuspallidi bilaterally and the lateral thalamic nuclei |
| 5 | 10 Months | Generalized slow background with Left temporal IED | Three electrographic seizures were recorded all focal arising from left hemisphere | MRI brain: Diffuse cerebral atrophy |
| 6 | 3 Months | Generalized voltage attenuation of background with no IED | Generalized electrodecremental (epileptic spasm ) | MRI brain: Interval progression of the diffuse cerebral atrophy. |
| 7 | 7 Months | Hypsarrhythmia with Multifocal IED | Generalized electrodecremental (epileptic spasm ) | MRI brain: bilateral symmetrical T2 hyperintensity involving the globus pallidi bilaterally and the lateral thalamic nuclei . |
| 8 | 4 Months | Normal for age background with Left temporal IED | Ictal discharges at left temporal region associated with clinical bradycardia | Normal MRI brain |
| 9 | 2 Months | Normal for age background with Bilateral temporal IED | Build up sharp waves on left temporal region mostly electrographic seizure | CT head : brain atrophy and craniosynostosis |
| 10 | Neonate | Normal for age background with multifocal IED | Generalized electrodecremental (epileptic spasm) | Normal brain US |
| 11 | 4 Months | Hypsarrhythmia withMultifocal IED | Generalized electrodecremental (epileptic spasm) | Normal MRI brain |
