Cognitive performance in women with polycystic ovarian syndrome: A pilot study

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.
