Abstract

The aim of this study was to evaluate the relationship of serum reproductive hormone levels with cognitive function and negative symptoms in schizophrenic women during the follicular phase of the menstrual cycle. Thirty-five women with chronic schizophrenia who had minimal positive symptoms participated in this study. We evaluated the correlation of serum reproductive hormone levels with the Scale for the Assessment of Negative Symptoms (SANS) and cognitive function tests such as the Immediate Visual Recognition Scale, Oral Fluency Test, List Recall Scale with List Acquisition Scale, Trail Making Tests A and B, and Digit Symbol Test. The patients were divided into two subgroups (low estradiol group and normal estradiol group) using the normal serum reference range for estradiol. Significant correlation between SANS subcategories, such as Alogia and Attention Impairment, and estradiol were found. Moreover, significant relationships between the estradiol level and the Oral Fluency Test, List Recall Scale with List Acquisition Scale, Trail Making Test B and Digit Symbol Test were observed. In the low estradiol group, the SANS scores, except for Anhedonia-Asociality and Avolition-Apathy, were significantly higher than those in the normal estradiol group. Patients in the low estradiol group had a significantly lower performance in the cognitive function tests, except Visual Recognition Scale, when compared to patients in the normal estradiol group. These results suggest that for schizophrenic women of reproductive age, lower levels of estrogen are associated with more severe negative symptomatology as well as reduced performance in cognitive function, especially verbal performance and executive functioning.
