Abstract:
The current study aimed to investigate the electroclinical differences between mesial temporal lobe epilepsy (MTLE) and posterior lateral temporal lobe epilepsy (PLTLE). All patients had Engel class I outcomes after surgery for at least one year. In MTLE patients, the epileptogenic zone was inside the boundary of a standard temporal lobectomy, whereas in PLTLE, the epileptogenic zone was behind the boundary of a standard temporal lobectomy. Febrile convulsion, history of psychic aura, oroalimentary automatism, and diffuse interictal epileptiform discharges were more frequent in MTLE. Theta wave and increasing heart rate were more evident at the seizure onset in MTLE, whereas an ictal onset fast rhythm was more evident in PLTLE. Tonic head turning was more frequent in PLTLE. Distinguishing between MTLE and PLTLE was easier than distinguishing MTLE from lateral TLE (LTLE), which may be helpful in planning epilepsy surgery. Combinations of these manifestations and signs can provide vital clues to distinguish between MTLE and PLTLE.

Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
