New studies show that experiencing a second childhood seizure may increase the chance that more are to follow. Dr Shlomo Shinnar, Neurologist and Paediatrician from the Montefiore Medical Centre in New York, explains a study of 407 children, in Annals of Neurology:
By following 407 children, for 16 years after their first seizure, Shinnar showed the risk of experiencing a second seizure was 29 per cent at 1 year, 37 per cent at 2 years, 43 per cent at 5 years, and 46 per cent at 10 years.
182 children had a second seizure, of these 72 per cent had a third, 58 per cent had four or more, and 29 per cent had 10 or more seizures.
He goes on to say that the risk of further seizures was higher if the first two occurred within two months, or if the child had an ongoing neurological condition, such as cerebral palsy. Shinnar adds," the majority of these kids only have a few seizures. They turn out to have relatively mild seizure disorders."
