Epilepsy Behav 2019 Feb 30;91:25-29. Epub 2018 Jun 30.

Epilepsy Center, Medical Center-University of Freiburg, Faculty of Medicine, University of Freiburg, Germany. Electronic address:

For patients with pharmacoresistant focal epilepsy, neurostimulation offers nonpharmacological strategies to improve seizure control. Vagus nerve stimulation (VNS), deep brain stimulation of the anterior thalamic nuclei, and responsive neurostimulation (RNS) are approved therapies which have shown efficacy in randomized short-term trials. Controlled data from prospective studies are needed to confirm reports on stable or even increasing evidence from studies with longer follow-up and to confirm that neurostimulation may offer advantages also regarding cognitive tolerability and sudden unexpected death in epilepsy (SUDEP)-risk.

[Immediate outcomes of microsurgical treatment of cerebral arteriovenous malformations in non-hemorrhagic patients].

Zh Vopr Neirokhir Im N N Burdenko 2018;82(6):30-37

Burdenko Neurosurgical Institute, Moscow, Russia.

Arteriovenous malformations (AVMs) are some of the most frequent congenital abnormalities of the cerebral vascular system and usually occur at a young age. Given the fact that AVMs can manifest, in addition to hemorrhages, as symptomatic epilepsy (17-40%) that occurs more often at a young age and may lead to significant disability, investigation of this pathology remains topical. Particular attention has recently been paid to the management of AVM patients without clinical signs of hemorrhage at the time of pathology diagnosis. Read More
