AB Seizures  are  caused  by  abnormal  electrical  discharges  in  the  brain.  Epilepsy  is  the  condition  of  recurrent  unprovoked  seizures.  The  definition  of  “provoked”  here  is  more  precise  than  in  common  parlance  and  refers  to  acute,  reversible  provoking  factors  causing  seizures.  For  example,  acute  hypoglycemia,  alcohol  withdrawal,  high  fever,  and  medication  or  drug  toxicity  are  all  acute  reversible  factors  that  can  provoke  seizures  (Table  18–1).  In  these  scenarios,  the  brain  may  be  structurally  normal,  but  exposure  to  the  acute  provoking  factor  leads  to  seizures.  When  the  cause  is  treated,  the  seizures  typically  improve  and  the  patient  is  not  necessarily  at  risk  for  future  recurrent  seizures.
