Bitemporal epilepsy
Epilepsy syndrome with seizure foci in both temporal lobes, making surgical treatment more challenging.
Full Definition
Bitemporal epilepsy is a complex epilepsy syndrome characterized by independent epileptogenic zones in both temporal lobes. This condition presents significant diagnostic and therapeutic challenges as seizures may originate from either hemisphere, sometimes making it difficult to identify a dominant focus. Patients typically require extensive monitoring with intracranial electrodes to determine lateralization and potential surgical candidacy. The bilateral nature often contraindicates standard temporal lobectomy, though selective procedures may be considered in cases with clear dominance of one side.
Usage
Usage note: Distinguish from bilateral temporal sclerosis, which refers to structural abnormalities rather than seizure localization.
