Abstract

Objective: To investigate the frequency of abnormal Neuroimaging and abnormal electroencephalogram findings in pediatric seizure disorder

Methods: A total of 153 patients (ages between 1 month to 12 years) were included from inpatient, outpatient and  emergency wards and evaluated as per standardized protocol over a period of 6 months . Seizure pattern was observed and routine investigations sent. CT scan was done in 93.4 %, MRI was done in 91.5%, and EEG was done in 83.6 % patients. Patients were categorized into provoked and unprovoked seizure, later investigations results were analysed in both groups

Results: Amongst the studied population generalized tonic clonic seizure was the most commonly observed seizure. MRI was found to be abnormal in 62.8% patients. EEG showed significant abnormality in 51.5%. Abnormal CT scan only in 46.1%. EEG and MRI were both found abnormal in 40.6% patients. There was a statistical significance between EEG and MRI at 99 CI (p<0.0001).

Conclusion: MRI and EEG form an essential part of evaluation for pediatric seizure disorder and often provide a deeper insight into the underlying abnormality. MRI is more sensitive for  yield of white matter abnormalities than CT scan.
