Objective: Epilepsy is considered as a network disorder of interacting brain regions. The propagation of local epileptic activity from the seizure onset zone (SOZ) along neuronal networks determines the semiology of seizures. However, in highly interconnected brain regions such as the insula, the association between the SOZ and semiology is blurred necessitating invasive stereoelectroencephalography (SEEG).

The purpose of this study was to compare the acute success and complication rates of CDT performed via transradial, transbrachial, and transfemoral access sites in patients with acute lower limb vascular occlusion and to investigate the 1-year outcomes of CDT and MT for ALI. Between 2008 and 2019, 84 consecutive patients with ALI were treated with CDT in a large community hospital.

- The study aimed to explore how episodic memory networks differ between patients with temporal lobe epilepsy (TLE) due to hippocampal sclerosis and healthy individuals, focusing on the parietal memory network (PMN) and its impact on memory performance after surgery.
- Using fMRI scans, the research involved 21 TLE patients and 28 healthy controls, comparing brain activations related to spatial memory tasks and linking these activations to memory scores post-surgery.
- Findings indicated that healthy subjects showed greater activation in several brain regions compared to TLE patients, particularly in areas related to the PMN; higher activation levels in certain regions were associated with better verbal and nonverbal memory performance in TLE patients after
Objective: Invasive video-electroencephalography (iVEEG) is the gold standard for evaluation of refractory temporal lobe epilepsy before second stage resective surgery (SSRS). Traditionally, the presumed seizure onset zone (SOZ) has been covered with subdural electrodes (SDE), a very invasive procedure prone to complications. Temporal stereoelectroencephalography (SEEG) with conventional frame-based stereotaxy is time-consuming and impeded by the geometry of the frame.

The Medtronic Registry for Epilepsy (MORE) aims to understand the safety and longer-term effectiveness of ANT DBS therapy in routine clinical practice.
Methods: MORE is an observational registry collecting prospective and retrospective clinical data.
