Mesial Temporal Lobe Epilepsy Management Strategies

Mesial temporal lobe epilepsy (MTLE) is the most common form of focal epilepsy in adults and often resists first-line drug therapy. Management requires a spectrum of approaches ranging from optimised antiseizure medication regimens to surgical resection, neuromodulation and dietary interventions. Advances in neuroimaging and genomics have refined patient selection for each strategy, while innovations in device-based treatments and gene therapy are expanding options for those with drug-resistant disease. A multidisciplinary framework—integrating neurology, neurosurgery, neuropsychology and radiology—underpins optimal outcomes. Globally, MTLE imposes significant social and economic burdens, driving research into safer, more effective and more personalised interventions.

Recent studies have exploited high-resolution diffusion imaging to identify white matter microstructural markers that predict seizure freedom after temporal lobectomy, enabling more accurate surgical planning. A phase II trial of an adeno-associated viral vector delivering a neuroinhibitory gene to hippocampal circuits demonstrated sustained reduction in seizure frequency for patients with drug-resistant MTLE. In parallel, optogenetic interrogation of hippocampal networks in rodent models has pinpointed critical circuit nodes for seizure initiation, informing the design of next-generation closed-loop neuromodulation devices that can detect and abort emerging seizures in real time.

Technical terms

Mesial temporal sclerosis: pathological scarring and neuronal loss in the hippocampus commonly associated with MTLE.

Anterior temporal lobectomy: surgical removal of the anterior segment of the temporal lobe to eliminate epileptogenic tissue.

Selective amygdalohippocampectomy: targeted resection of the amygdala and hippocampus with sparing of surrounding cortical areas.

Vagus nerve stimulation: neuromodulation technique delivering programmed electrical pulses to the vagus nerve to reduce seizure frequency.

Responsive neurostimulation: closed-loop system that detects abnormal electrical activity and delivers targeted stimulation to abort impending seizures.
