BACKGROUND The authors aimed to evaluate the feasibility/safety of stereo-electroencephalography (SEEG) and SEEG-guided radiofrequency thermocoagulation (RFTC) in patients with drug-resistant epilepsy previously implanted with neuromodulation devices, using a retrospective cohort design evaluating patients treated at the Mayo Clinic Florida Epilepsy Center. OBSERVATIONS Nine patients (mean age 36.3 ± 10.9 years, 33% female) with prior implantation of neuromodulation devices were included. A vagus nerve stimulator was present in 8 of 9 patients, and 4 patients had undergone previous intracranial neuromodulation. Five patients underwent SEEG-RFTC. The mean SEEG monitoring duration was 6.5 ± 2.9 days. No intraoperative or procedural complications occurred, including hardware-related issues. No permanent or significant neurological/cognitive deficits occurred. One patient experienced transient postoperative neurological symptoms attributed to perilesional edema. Seizure reduction ranged from 50% to 75% following SEEG-RFTC. LESSONS SEEG and SEEG-RFTC are feasible in patients who have implanted neuromodulation devices, including intracranial implants. These procedures may be performed without interference with existing hardware and provide meaningful seizure reduction in highly refractory populations. Further studies with larger cohorts and longer follow-up are needed to better define efficacy and patient selection. https://thejns.org/doi/10.3171/CASE26376

Understanding the evolution of clinical tools and models of care is fundamental to advancing the field of epilepsy. The 2025 American Epilepsy Society Annual Course examined the expanding spectrum of epilepsy care through the integration of multispecialty collaboration, innovative diagnostic modalities, and surgical and nonsurgical therapeutic interventions. The course underscored significant global advancements in epilepsy research and practice. This comprehensive review synthesizes key educational insights from the program, offering a critical perspective on the ongoing transformation of epilepsy care.

Abstract Objective Clinical neuropsychology is an evidence-based discipline that draws heavily from the field’s peer-reviewed journal articles. However, our scientific understanding of the methods and content that comprise the articles published in clinical neuropsychology journals is quite limited. Method A mixed methods approach was used to describe the aims, methods, and content of clinical neuropsychology’s major lifespan journals. Six-hundred articles were randomly sampled from the 2020–2024 volumes of six lifespan clinical neuropsychology journals. All articles were coded across 42 dimensions, including article type, population, design, methods, ability domains, and miscellaneous topics (e.g., brain health). The aims/scope sections of the journals were subjected to qualitative analyses, to identify relevant themes. Results The most common article content was observed in the areas of empirical/data-driven studies, cross-sectional and observational designs, older and neurological participants, cognitive testing of higher-order abilities, and psychometrics/methods. Results showed significant between-journal differences for some of these content areas at broadly medium effect sizes (e.g., experimental design, brain health topics). Qualitative analyses yielded five shared themes, suggesting that the lifespan clinical neuropsychology journals are interested in submissions on brain-behavior relationships, clinical applications, both clinical and healthy/typical populations, professional/guild matters, and multidisciplinary investigations. Conclusions The scientific content published within clinical neuropsychology’s six primary lifespan journals varies in some dimensions, but largely focuses on cross-sectional, observational studies of psychometrics and higher-order cognition. The implications of these findings for future research in clinical neuropsychology are contextualized for authors, reviewers, and readers.

AbstractObjectiveFocused ultrasound ablation (FUSA) is an emerging treatment for neurological and psychiatric diseases. We describe the initial experience from a pilot, open‐label, single‐center clinical trial of unilateral anterior nucleus of the thalamus (ANT) FUSA in patients with treatment‐refractory epilepsy.MethodsTwo adult subjects with treatment‐refractory, focal onset epilepsy were recruited. The subjects received ANT FUSA using the Exablate Neuro (Insightec) system. We determined the safety and feasibility (primary outcomes), and changes in seizure frequency (secondary outcome) at 3, 6, and 12 months. Safety was assessed by the absence of side effects, that is, new onset neurological deficits or performance deterioration on neuropsychological testing. Feasibility was defined as the ability to create a lesion within the anterior nucleus. The monthly seizure frequency was compared between baseline and postthalamotomy.ResultsThe patients tolerated the procedure well, without neurological deficits or serious adverse events. One patient experienced a decline in verbal fluency, attention/working memory, and immediate verbal memory. Seizure frequency reduced significantly in both patients; one patient was seizure‐free at 12 months, and in the second patient, the frequency reduced from 90–100 seizures per month to 3–6 seizures per month.SignificanceThis is the first known clinical trial to assess the safety, feasibility, and preliminary efficacy of ANT FUSA in adult patients with treatment‐refractory focal onset epilepsy.
