Infecção crônica por Toxoplasma gondii está associada à diminuição de desempenho da memória de trabalho em mulheres

Abstract

Abstract Objective The present study sought to investigate changes in mood, inhibitory control, and working memory associated with T. gondii infection in a sample of Brazilian women. Method Twenty-eight female participants were equally distributed into two groups, according to the serology for chronic infection by T. gondii. The participants answered a Sociodemographic questionnaire, the CES-D, and performed Simon and N-Back tasks. Results Infected participants presented less accuracy and longer response time in N-Back tasks. No significant differences were found in the Simon task performance or in the depression levels. Conclusion Our findings suggest that chronic infection by T. gondii may result in impaired working memory and point out the importance of public policies aiming at preventing this infection.
