fischer 2014 recurrence risk is a function of time, such that the longer the time since the last seizure, the lower the risk. otherwise, the task force did not agree on a specific interval of time between seizures that would “reset the clock” for counting an event as a second seizure. a rationale for setting such an interval might emerge from future research. recurrence risk depends on the type of epilepsy, age, syndrome, etiology, treatment, and many other factors. the risk of seizure recurrence after unprovoked seizures diminishes with time, although the risk may never reach levels for normal individuals who have not had a prior seizure.most relapses are early. after a single unprovoked seizure, 80%14,17 to 90%25 of those who had a second did so within 2 years. in one study,5 after a second unprovoked seizure, subsequent seizures occurred within 4 years, but none in the ensuing 3 years, suggesting that the risk may not be zero but is low. the national general practice study of epilepsy in the united kingdom14 identified a 3-year recurrence risk of 44% after a seizure-free period of 6 months, 32% after 12 months,and 17% after 18 months. no adequate data are available on seizure recurrence risk after being seizure-free and off medication for extended periods of time. delayed relapses are rare after 5 years. by 10 years off antiseizure medicines, the annual risk for seizures probably is very low.

Fischer 2014 Recurr risk is a function of time, such that the longer the time sinc the last seizure, the lower the risk. Otherwise, the Task Forc did not agre on a specif interv of time between seizur that would “reset the clock” for count an event as a second seizure. A rational for set such an interv might emerg from futur research. Recurr risk depend on the type of epilepsy, age, syndrome, etiology, treatment, and mani other factors. The risk of seizur recurr after unprovok seizur diminish with time, although the risk may never reach level for normal individu who have not had a prior seizure.Most relaps are early. After a singl unprovok seizure, 80%14,17 to 90%25 of those who had a second did so within 2 years. In one study,5 after a second unprovok seizure, subsequ seizur occur within 4 years, but none in the ensu 3 years, suggest that the risk may not be zero but is low. The Nation Gener Practic Studi of Epilepsi in the Unite Kingdom14 identifi a 3-year recurr risk of 44% after a seizure-fre period of 6 months, 32% after 12 months,and 17% after 18 months. No adequ data are avail on seizur recurr risk after be seizure-fre and off medic for extend period of time. Delay relaps are rare after 5 years. By 10 year off antiseizur medicines, the annual risk for seizur probabl is veri low.
