Abstract (English): Background: Anticonvulsants are an essential treatment for bipolar disorder; however, there is relatively little known about their use in older age bipolar disorder (OABD). In this paper, which leverages a large international dataset, we aim to 1) describe the use of anticonvulsants in OABD compared to younger age bipolar disorder (YABD; ages <50 years old) and 2) explore any demographic/clinical correlates. Methods: A secondary analysis was conducted on the international data from the Global Aging and Geriatric Experiments in Bipolar Disorder project. The main objective was to report the prevalence of anticonvulsant use in OABD over 50 years old (mean age = 62.27) and the most prescribed anticonvulsant. Additional analysis explored any demographic and clinical correlates associated with anticonvulsant use. Generalized linear mixed models were used for this analysis. Results: Of the 2,691 participants with bipolar disorder who had anticonvulsant prescribing data, 34.4% (n = 926) used anticonvulsants at the time of study. Rates of anticonvulsant prescribing did not significantly differ between OABD and YABD groups (36.7% (n = 666) vs. 29.7% (n = 260)). Anticonvulsant prescribing patterns for OABD and YABD did not significantly differ, with valproate as the most prescribed anticonvulsant. OABD anticonvulsant users had less lithium use, more antidepressant use, more rapid cycling, more mood episodes and more cardiovascular comorbidities compared to nonusers. Conclusion: Anticonvulsant use was similar in OABD and YABD. A number of important clinical correlates of anticonvulsant use were identified. [ABSTRACT FROM AUTHOR]
Abstract (French): Les anticonvulsivants sont un traitement essentiel contre le trouble bipolaire, mais leur utilisation pour traiter les troubles bipolaires du sujet âgé est relativement peu connue. Dans cet article, lequel s'appuie sur un vaste ensemble de données internationales, nous visons 1) à décrire l'utilisation des anticonvulsivants pour traiter les troubles bipolaires du sujet âgé par rapport à leur utilisation pour traiter les troubles bipolaires du sujet jeune (< 50 ans) et 2) à explorer toute corrélation démographique/clinique. Une analyse secondaire des données internationales tirées du projet Global Aging and Geriatric Experiments in Bipolar Disorder (GAGE-BD) a été menée. L'objectif principal était de faire état de la prévalence de l'utilisation d'anticonvulsivants pour traiter les troubles bipolaires du sujet âgé chez les personnes de plus de 50 ans (âge moyen : 62,27 ans) et de l'anticonvulsivant le plus prescrit. Une analyse supplémentaire a permis d'examiner chaque corrélat démographique et clinique associé à l'utilisation d'anticonvulsivants. Des modèles linéaires mixtes généralisés ont été utilisés dans le cadre de cette analyse. Sur les 2 691 participants atteints de trouble bipolaire pour lesquels des données sur la prescription d'anticonvulsivants étaient disponibles, 34,4% (n = 926) prenaient des anticonvulsivants au moment de l'étude. Les taux de prescription d'anticonvulsivants ne différaient pas de façon significative entre les groupes de troubles bipolaires du sujet âgé et le groupe de troubles bipolaires du sujet jeune (36,7% [n = 666] contre 29,7% [n = 260]). Les modèles de prescription d'anticonvulsivants pour les troubles bipolaires du sujet âgé et les troubles bipolaires du sujet jeune ne différaient pas de façon significative, le valproate étant l'anticonvulsivant le plus prescrit. Les personnes atteintes de troubles bipolaires du sujet âgé qui prenaient des anticonvulsivants ont pris moins de lithium et plus d'antidépresseur, ont présenté des cycles plus rapides, davantage de fluctuations de l'humeur et davantage de maladies cardiovasculaires concomitantes par rapport à celles qui n'en prenaient pas. L'utilisation d'anticonvulsivants était similaire pour traiter les troubles bipolaires du sujet âgé et ceux du sujet jeune. Un certain nombre de corrélats cliniques importants de l'utilisation d'anticonvulsivants ont été définis. [ABSTRACT FROM AUTHOR]
