Objective: Eating-induced seizures (EIS) are a rare form of reflex seizures. The objective of this study was to report a series of cases of EIS involving patients admitted to our epilepsy unit, and to analyze the clinical characteristics, etiology, and treatment response of this type of infrequent seizure., Methods: We performed a single-center retrospective analysis of all consecutive patients diagnosed with epilepsy with eating-induced seizures between 2008 and 2020., Results: We included eight patients (six women) with mean age 54.75 years (range: 40-79), and mean age at epilepsy onset 30.75 years (range: 9-58 years). EIS were triggered during a meal in 5/8 (at dinner 1/8, at breakfast in 1/8, and without time preference in 3/8), by a certain flavor in 1/8, by eating different textures or drinking soft drinks in 1/8, and by slicing food in 1/8. All patients suffered nonreflex seizures and 3/8 other types of reflex seizures. In 6/8 of patients, EIS originated in the right hemisphere. In 5/8, the EIS progressed to impaired awareness with oromandibular automatisms. In 6/8, the epilepsy was drug-resistant. Temporopolar encephalocele was the most frequent etiology, in 4/8. Three of the eight underwent surgical treatment, with Engel IA 1 year in 3/3. Three of the eight were treated with vagal stimulation therapy, with McHugh A 1 year in 2/3., Significance: In our series, eating-induced seizures were observed in patients with focal epilepsy. It was frequently drug-resistant and started predominantly in the right hemisphere, due to temporal pole involvement in half of the patients., (© 2023 International League Against Epilepsy.)

Background and Objectives: First-line treatment for trigeminal neuralgia (TN) is limited to carbamazepine and oxcarbazepine, and in refractory cases, alternatives are scarce. Lacosamide has been suggested as a valid option. In this study, we describe a series of patients who received oral lacosamide as treatment for TN after first-line drug failure., Methods: In this retrospective descriptive cohort study, we included patients with refractory TN who attended a tertiary center between 2015 and 2021 and were prescribed oral lacosamide after first-line treatment failure. The primary endpoints were pain relief and adverse effects. We secondarily analyzed clinical outcomes and compared responders versus nonresponders in the search for potential predictors of response., Results: Eighty-six patients were included (mean age: 62 [SD 15.6] years; 54/86 [63%] female). The TN etiology was secondary in 16/86 (19%) patients. Concomitant continuous pain was present in 29/86 (34%) patients. The mean number of previous treatments was 2.7 [SD 1.5]. Pain relief was achieved in 57/86 (66%) cases, with 28/86 (33%) patients presenting adverse effects, all of which were mild. No statistically significant differences were observed between responders and nonresponders, but subtle clinical differences suggested potential predictors of response., Conclusion: Lacosamide may be an effective and relatively safe treatment for refractory pain in TN patients after first-line treatment failure., (© 2023 The Authors.
