AB A  seizure  (from  the  Latin  sacire,  “to  take  possession  of”)  is  a  transient  occurrence  of  signs  or  symptoms  due  to  abnormal  excessive  or  synchronous  neuronal  activity  in  the  brain.  Depending  on  the  distribution  of  discharges,  this  abnormal  brain  activity  can  have  various  manifestations,  ranging  from  dramatic  convulsive  activity  to  experiential  phenomena  not  readily  discernible  by  an  observer.  Although  a  variety  of  factors  influence  the  incidence  and  prevalence  of  seizures,  ~5–10%  of  the  population  will  have  at  least  one  seizure,  with  the  highest  incidence  occurring  in  early  childhood  and  late  adulthood.
