RENDIMIENTO COGNITIVO EN MUJERES CON SÍNDROME DE OVARIO POLIQUÍSTICO: UN ESTUDIO PILOTO (Cognitive Performance in Women with Polycystic Ovarian Syndrome: A Pilot Study)

Sara Herreño, Yolanda del Río-Portilla

Resumen


El Síndrome de ovario poliquístico (SOP) es la enfermedad endocrina-metabólica más frecuente en las mujeres en edad reproductiva. A pesar de su alta prevalencia, hay pocas investigaciones que analizan los efectos de los cambios hormonales sobre la cognición de pacientes con SOP. Objetivo: comparar el rendimiento en habilidades cognitivas y los niveles de hormonas sexuales de un grupo de pacientes con SOP y con las de un grupo control. Método: Participaron 20 mujeres mayores de 21 años, sin tratamiento hormonal, dividas en dos grupos, el primero compuesto por 10 pacientes diagnosticadas con SOP según los criterios de Rotterdam (GSOP) y el otro, de control, compuesto por 10 mujeres sin diagnóstico de SOP (GCT). Se aplicaron las pruebas WAIS III y fluidez verbal semántica y fonológica de la batería NEUROPSI Atención y memoria, y se realizaron análisis sanguíneos de hormonas sexuales. Resultados: Las pacientes del GSOP obtuvieron puntajes inferiores a las del GCT en el CI Verbal (p=0.009), CI Total (p=0.029), índice de comprensión verbal (p=0.005), índice de memoria de trabajo (p=0.023) y en la prueba de fluidez verbal semántica (p=0.029). No se encontraron diferencias significativas en los niveles hormonales. Conclusión: el GSOP presentó menor rendimiento que el GCT en pruebas de tipo verbal, aunque no se presentó déficit en su ejecución. Se sugiere estudiar la relación de la insulinorresistencia con la cognición en pacientes con SOP.

Abstract

Polycystic ovarian syndrome (PCOS) is the most common endocrine-metabolic disease in women of reproductive age. Despite its high prevalence, little research analyzes the effects of hormonal changes on cognition in patients with PCOS. Objective: To compare the performance in cognitive abilities and sexual hormone levels of a group of patients with PCOS and those of a control group. Method: Twenty women older than 21 years, without hormone treatment, divided in two groups, the first consisting by 10 patients diagnosed with PCOS according to the Rotterdam criteria (GSOP), and the other composed of 10 women without diagnosis of PCOS (GCT). WAIS III and semantic and phonological verbal fluency tests of the NEUROPSI attention and memory test battery were applied, and blood analyzes of sexual hormones were analyzed. Results: The GSOP patients obtained lower scores than the GCT in Verbal IQ (p=0.009), full scale IQ (p=0.029), verbal comprehension index (p=0.005), working memory index (p=0.023) and semantic verbal fluency test (p=0.029). No significant differences were found in sexual hormone levels. Conclusion: the GSOP showed lower performance than the GCT in verbal tests, although there was not deficit in its execution. It is suggested to study the relationship of insulin resistance with cognition in patients with GSOP. 

Keywords: Polycystic Ovary Syndrome (PCOS), Gonadal Hormones, Sexual Hormones, Cognition, Cognitive Functioning.
