Necessity of EEG and CT scan For Accurate Diagnosis of Idiopathic (Partial / Generalised) Seizures in Children

Objective: To study the importance of EEG and CT scan as a diagnostic aid for accurate diagnosis in various seizure disorders in children from Bhubaneswar,Orissa,India. Design: Cross-sectional. Setting: Urban teritiary care teaching hospital. Method: A total of 52 children with seizure disorder were included; 26 of them were having partial seizures, while the rest (26) were having generalised seizures. Those patients who were having known aetiological factors were excluded from the study. All the patients were subjected to a detailed clinical history and physical examination. An EEG and CT scan were also performed on every patient. Results: Abnormal EEG was found in 73% and 76.9% of patients with partial and generalised seizures respectively, while abnormal CT scan was found in 50% of patients with partial seizures and 34.6% of patients with generalised seizures. It was also observe d that with increasing abnormalities in EEG, the chance of finding some abnormality in CT increases. Summary and conclusion: It is recommended that every case of idiopathic seizures must be evaluated with EEG as well as CT scan .
