Long term monitoring peri ictal lateralizing signs

Focal epilepsies

Anatomic localization

Seizure focus can be at considerable distance from symptomatic zone

Propagation of Ictal patterns are variable

Seizures may be originated from silent brain regions

No signs or symptoms can be considered pathogonomonic of the anatomic localization

Combining semiologic, electrophysiologic, neuroimaging, and other data provide important localizing information


Complex partial seizures cpss

complexpartialseizures(CPSs)

CPSs refers to a partial - onset seizure with impairment of consciousness, (ILAE,1981).

Seizures associated with MTLE are more correctly referred to as limbic seizures, whether or not consciousness is impaired


Peri ictal lateralizing signs lss

Peri-ictal lateralizing signs (LSs)

  • LSs may help in presurgical evaluation of adults and young and preverbal children

  • Some LSs consistently lateralize seizure onset in all ages and some only at the end of first decade.

  • Some LSs have a high predictive values

  • Because of testing difficulties assessing some LSs is difficult in children

  • Are observed more frequently in older children

  • Lack of LSs occur more frequently among younger children. (<6.7 years)
