Association of Cytomegalovirus and Toxoplasma gondii Antibody Titers With Bipolar Disorder

Abstract

Background: The association between infectious agents and mental health disorders has garnered significant attention in recent years, particularly in relation to bipolar disorder. The literature reveals a complex interplay between Toxoplasma gondii and cytomegalovirus (CMV) infections and their potential roles in the pathogenesis of bipolar disorder.   Literature Review: (Lindgren et al., 2020) provide a foundational examination of the seropositivity rates for T. gondii and CMV, noting a correlation between these infections and mental health disorders, including increased suicide attempts among individuals with mood disorders. Further, (A. Virus et al., 2021) delve into the neurobiological mechanisms by which T. gondii may induce oxidative stress and immune-inflammatory responses. Their research indicates a significant association between T. gondii seropositivity and a history of bipolar disorder type I, suggesting that this parasite could influence mood dysregulation through biological pathways similar to those observed in bipolar disorder. (Ali Mofazzal Jahromi et al., 2022) expand the discussion to include neurotropic infections, reporting that increased seropositivity to T. gondii and CMV correlates with cognitive impairments in patients with bipolar disorder. This finding implies a shared pathogenic pathway among these infections and mental health conditions. Conclusion: In conclusion, the reviewed literature underscores a critical narrative regarding the association of Toxoplasma gondii and CMV with bipolar disorder. There is compelling evidence supporting the notion that these infectious agents may contribute to the development and exacerbation of bipolar disorder through various biological mechanisms, highlighting the importance of considering infectious agents in mental health assessments. Future research is warranted to further elucidate these relationships and to explore potential therapeutic implications.
