摘要
Temporal lobe epilepsy(TLE)is difficult to treat as it is often refractory to treatment.Apart from traditional medical treatment,surgical resection is also a choice of treatment,but it may be associated with significant cognitive deficits.As a result,treatment strategies using targeted and adjustable stimulation of malfunctioning brain circuits have been developed.These neuromodulatory therapies using approaches of electric and magnetic neuromodulation are already in clinical use for refractory epilepsy while others such as optogenetics,chemo-genetics and ultrasound modulation are being tested in pre-clinical TLE animal models.In this review,we conducted an in-depth literature search on the clinically available neuromodulatory approaches for TLE,focusing on the possible mechanism of action and the clinical outcomes including adverse effects.Techniques that are currently explored in preclinical animal models but may have therapeutic applications in future are also discussed.The efficacy and subsequent adverse effects vary among the different neuromodulatory approaches and some still have unclear mechanisms of action in TLE treatment.Further studies evaluating the benefits and potential limitations are needed.Continued research on the therapeutic mechanisms and the epileptic brain network is critical for improving therapies for TLE.
