Introduction: Seizure is the most common neurological illness in pediatric population and its risk is highest in the first year of life. Studies regarding etiology of afebrile seizures worldwide and in India are limited; hence, the current study was undertaken. Objective: The objective of this work was to study the etiology of afebrile seizures in infants aged 1 month to 1 year. Materials and Methods: A retrospective study of afebrile infantile seizure was conducted at pediatric neurology outpatient department between January 2015 and September 2017. All children with first episode of afebrile seizures were included. Biochemical and hematological investigations, imaging, and electroencephalogram were performed whenever necessary. Simple descriptive statistics were used to analyze the data in the form of frequencies with percentages and median as applicable. Results: One hundred twenty-one children with a mean age of 8.1 months were analyzed. Of these children, 58% were males. Positive family history was found in 1.65% children, developmental delay in 70%, and dysmorphism in 8%. Presenting seizure type were generalized (74%), focal (21%), and unknown (6%) onset. Etiology was deducible in 92% cases. Structural etiology was the most common (66%), followed by metabolic (12%), infections (7%), and others (6%). In structural pathology, common causes were perinatal insult (38%) and cerebral malformations (18%). Imaging was done in 98 cases and yield was 83% (85 cases). Conclusion: Etiology was deducible in 92% of children. Seizures due to structural etiology, secondary to perinatal insult followed by metabolic and infections, are important causes. Imaging aids are important in etiological diagnosis. Etiological evaluation should be considered in children following first episode of afebrile seizures, especially in developing countries like India.
