Introduction:

In patients with refractory temporal lobe epilepsy who are not candidates for surgery, electrical brain stimulation should be considered as another option.

Contents:

Electrical brain stimulation is the direct administration of electrical pulses to nerve tissue that modulates a pathological substrate, interrupts the clinical manifestation of seizures, and reduces their severity. Thus, given the importance of these treatments for patients with refractory temporal lobe epilepsy, four types of electrical stimulation are reviewed. The first, vagus nerve stimulation, is a good option in focal seizures and generalized or multifocal seizures. The second, hippocampal stimulation, is more useful in patients who are not candidates for lobectomy due to the risk of memory loss, with normal MRI or without mesial temporal sclerosis. The third, the anterior nucleus, is mainly in patients with focal seizures, but with caution in patients at high risk of cognitive changes such as the elderly, or in those with baseline mood disturbance and, finally, the centromedian nucleus is recommended for the treatment of focal seizures in Rasmussen's syndrome and tonic-clonic seizures in Lennox-Gastaut syndrome.

Conclusions:

the interest in brain electrical stimulation has been increasing as well as the target structures in which it can be applied because it is a safe and effective treatment in patients with temporal lobe epilepsy to control seizures, decreasing morbidity and mortality and increasing quality of life
