In a cross-sectional study, we evaluated the impact of the chronic use of benzodiazepines (BDZ) prescribed for seizure control on the anxiety levels of patients with temporal lobe epilepsy. We assessed the anxiety level of 99 patients with temporal lobe epilepsy with (n=15) or without (n=84) BDZ for seizure control, using the Beck Anxiety Inventory (BAI) or the Hamilton Anxiety Scale (HAMA). Independent risk factors for high anxiety levels were being a female patient (O.R.=2.93; 95% C.I.=1.05-8.16; p=0.039), having uncontrolled seizures (O.R.=4.49; 95% C.I.=1.66-12.11; p=0.003) and having a history of a psychiatric disorder (O.R.=4.46; 95% C.I.=1.63-12.21; p=0.004). However, there were no statistically significant differences in anxiety levels between patients utilizing or not utilizing BDZ prescribed exclusively for seizure control. We concluded that in our study, patients with chronic use of BDZ prescribed exclusively for seizure control showed similar anxiety levels than patients who were not using this class of drug. Additional studies are needed to define better strategies for the treatment of anxiety disorders in epilepsy.

Interplay of epilepsy and long-term potentiation: implications for memory.
Front Neurosci
January 2025
Department of Neurophysiology, Instituto Nacional de Neurología y Neurocirugía "Manuel Velasco Suárez", Mexico City, Mexico.
The interplay between long-term potentiation (LTP) and epilepsy represents a crucial facet in understanding synaptic plasticity and memory within neuroscience. LTP, a phenomenon characterized by a sustained increase in synaptic strength, is pivotal in learning and memory processes, particularly in the hippocampus. This review delves into the intricate relationship between LTP and epilepsy, exploring how alterations in synaptic plasticity mechanisms akin to those seen in LTP contribute to the hyperexcitable state of epilepsy.

Background: Refractory epilepsy poses significant challenges in clinical management due to its resistance to standard antiepileptic therapies, necessitating the exploration of more effective treatment regimens. Lamotrigine, with its proven efficacy and tolerability, offers potential benefits when combined with traditional medications like valproate, though its comprehensive impact on clinical outcomes and neurological markers requires further study.
Objective: To analyze the improvement effect of combined application of lamotrigine on refractory epilepsy patients and its impact on patients' EEG and neurological function.
Characterizing the fecal microbiome in patients on the ketogenic diet for drug resistant epilepsy.

McMaster University, Department of Pediatrics, Hamilton, ON, Canada.
Background: The ketogenic diet is a dietary therapy with anti-seizure effects. The efficacy of the diet is variable, with initial animal studies suggesting the intestinal microbiome may have a modulating effect. Initial research on the role of the human microbiome in pediatric epilepsy management has been inconclusive.

Background: Anesthesia depth influences seizure quality in patients undergoing electroconvulsive therapy (ECT). EEG-based neuromonitoring has been shown to detect adequate anesthesia depth for ECT. Anesthesia depth-guided ECT management may therefore be a reliable alternative to the predetermined anesthesia-to-stimulation time interval.

Objectives: (1) Gain insight into the mechanisms of postoperative delirium (POD). (2) Determine mechanistic overlap with post-ictal delirium (PID). Epilepsy patients undergoing intracranial electrophysiological monitoring can experience both POD and PID, and thus are suitable subjects for these investigations.
