Epilepsy patients experience chronic mitochondrial oxidative stress and increased levels of pro-inflammatory mediators, recognizable hallmarks of biological aging; however, few studies have explored aging markers in epilepsy. Herein, we addressed for the first time the impact of ASDs on molecular aging by measuring the telomere length (TL) and mtDNA copy number (mtDNA-CN). Methods: We used real-time quantitative PCR (QPCR) in epilepsy patients compared to matched healthy controls (CTs) and assessed the association with plasma levels of ASDs and other clinical variables. The sample comprised 64 epilepsy patients and 64 CTs. Patients were grouped based on monotherapy with lamotrigine (LTG) or valproic acid (VPA), and those treated with a combination therapy (LTG + VPA). Multivariable logistic regression was applied to analyze the obtained data. Results: mtDNA-CN was similar between patients and controls, and none of the comparisons were significant for this marker. TL was shorter in not seizure-free patients than in CTs (1.50 \u00b1 0.35 vs. 1.68 \u00b1 0.34; p &lt; 0.05), regardless of the ASD therapy. These patients exhibited the highest proportion of adverse drug reactions. TL was longer in patients on VPA monotherapy, followed by patients on LTG monotherapy and patients on an LTG + VPA combined scheme (1.77 \u00b1 0.24; 1.50 \u00b1 0.32; 1.36 \u00b1 0.37, respectively; p &lt; 0.05), suggesting that ASD treatment differentially modulates TL. Conclusions: Our findings suggest that clinicians could consider TL measurements to decide the best ASD treatment option (VPA and\/or LTG) to help predict ASD responses in epilepsy patients.<\/jats:p>","DOI":"10.3390\/jcm14010255","type":"journal-article","created":{"date-parts":[[2025,1,6]],"date-time":"2025-01-06T06:43:04Z","timestamp":1736145784000},"page":"255","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Valproic Acid and Lamotrigine Differentially Modulate the Telomere Length in Epilepsy Patients"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-7694-6430","authenticated-orcid":false,"given":"Salvador","family":"S\u00e1nchez-Badajos","sequence":"first","affiliation":[{"name":"Doctorado en Ciencias Biol\u00f3gicas y de la Salud, Universidad Aut\u00f3noma Metropolitana, Mexico City 04960, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2803-9444","authenticated-orcid":false,"given":"Alberto","family":"Ortega-V\u00e1zquez","sequence":"additional","affiliation":[{"name":"Departamento de Sistemas Biol\u00f3gicos, Universidad Aut\u00f3noma Metropolitana Unidad Xochimilco, Mexico City 04960, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marisol","family":"L\u00f3pez-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Departamento de Sistemas Biol\u00f3gicos, Universidad Aut\u00f3noma Metropolitana Unidad Xochimilco, Mexico City 04960, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2611-0972","authenticated-orcid":false,"given":"Nancy","family":"Monroy-Jaramillo","sequence":"additional","affiliation":[{"name":"Departamento de Gen\u00e9tica, Instituto Nacional de Neurolog\u00eda y Neurocirug\u00eda Manuel Velasco Su\u00e1rez (INNNMVS), Mexico City 14269, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,3]]},"reference":[{"unstructured":"WHO (2024, December 12).
