Table 2. Features of focal seizures of lateral temporal lobe origin.

Clinical features
 Typically no history of febrile seizure
 Auras common. Hallucinations (especially auditory) or illusions more suggestive of

lateral rather than mesial temporal origin, but any other temporal lobe aura may occur
 The motionless stare and the automatisms are similar to those in medial temporal lobe

epilepsy

EEG
 Spikes and focal discharges from the temporal region
 Spikes may have a lateral (posterior) temporal maximum, rather than an anterior

temporal/sphenoidal maximum. Polyspikes are more commonly seen with neocortical
generators

Imaging
 Structural changes (especially malformation of cortical development, benign tumour,

glioma, post traumatic changes, cavernous angioma)

This table includes those clinical features particularly characteristic of temporal lobe epilepsy. In many
cases, however, these features do not occur.
