Generalized 3-4 Hz spike and slow wave complexes on EEG are seen in? 
Select and explain. 
A. Generalized tonic clonic seizure, B. Absent seizure, C. Temporal lobe epilepsy Simple paial seizures, D. Juvenile myoclonic epilepsy
D: Juvenile myoclonic epilepsy
Answer: D: Juvenile myoclonic epilepsy 
Explanation: Juvenile myoclonic epilepsy REF: Clinical Electroencephalography by Misra Page 188 "In Juvenile myoclonic epilepsy the background activity of EEG is normal. Interictal EEG reveals generalised 4-6 Hz polyspikes and slow wave complexes" In Generalized tonic clonic seizure EEG shows a normal background with generalized epileptiform discharges such as spike or polyspike wave complexes at 2.5 to 4 Hz. On the EEG, typical absence seizures are associated with generalized, bilaterally synchronous, frontally predominant 3 Hz spike-and-wave discharges that begin suddenly from a normal background and end abruptly, without postictal slowing
