Risk factors for recurrence of febrile convulsions
- 52 Downloads
A cohort of hundred children with febrile convulsions, in the age group of 3 months to 5 years were followed up prospectively for one year to study the natural course of the illiness, and to determine if specific factors would increase the risk of recurrence of febrile convulsions.
The risk factors studied were age of onset under one year, long duration of convulsion (more than 15 minutes), family history of febrile convulsion or epilepsy and combination of two or all of the above factors. Four groups of children with different risk factors were followed up for recurrence of convulsion, after the first attack. A group of children without any risk factor was considered as control and they were also followed up for recurrence of convulsions.
Though all the groups with the risk factors, showed a trend towards a higher recurrence rate when compared to controls, the difference observed clinically was not significant statistically. This could be due to the small sample size of each group. A larger study could throw light on the predictive value of these risk factors and narrow down the use of long term anticonvulsant prophylaxis.
