Dentro de los llamados trastornos del estado de ánimo, el trastorno bipolar ha sido poco estudiado, a pesar de su prevalencia y el grado de incapacidad que produce en la población. Para comprender adecuadamente los factores causales de un trastorno es necesaria la investigación básica. Sin embargo, la falta de un modelo animal satisfactorio en el caso del trastorno bipolar dificulta el progreso en el conocimiento de sus bases neurobiológicas. Esta revisión pretende aunar las recientes aportaciones realizadas en referencia al trastorno bipolar, y aportar así una visión de conjunto que ayude a esclarecer la línea causal, partiendo del nivel más básico: el componente genético subyacente. En concreto, este trabajo presenta evidencia sobre los avances obtenidos gracias a modelos animales de ratones mutantes de genes implicados en la regulación de los ritmos circadianos, foco actual de la hipótesis etiopatogénica del trastorno bipolar.
Despite its prevalence and degree of disability, bipolar disorder has not received the attention it deserves within the so-called mood disorders. To properly understand the factors associated with its origin, basic research is needed. However, the lack of a satisfactory animal model hinders progress in understanding the neurobiological basis that gains importance in explaining this condition. This review, therefore, aims to combine the recent contributions about bipolar disorder, and thus provide an overview to help clarify the causal line, starting from the most basic level: the underlying genetic component. Specifically, this paper presents evidence on the progress achieved with animal models of mutant mice of genes involved in regulating circadian rhythms, current focus of etiopathogenic hypothesis of bipolar disorder.
