AB A  seizure  is  an  episode  of  abnormal  neurologic  function  caused  by  inappropriate  electrical  discharge  of  brain  neurons.  Neuronal  electrical  discharge,  in  its  most  simple  form,  can  be  thought  of  as  the  homeostasis  of  glutaminergic  (excitatory)  and  γ-aminobutyric  acid  (inhibitory)  activity.  The  seizure  is  the  clinical  attack  experienced  by  the  patient  in  the  setting  of  inappropriate  excitatory  activity.  Some  patients  with  "epileptic"  electroencephalographic  (EEG)  discharges  may  not  experience  any  overt  clinical  symptoms.  Some  seizure-like  episodes  may  be  due  to  causes  other  than  abnormal  brain  electrical  activity,  but  such  attacks  are  not  true  seizures.
