Executive functions in men and postmenopausal women.

INTRODUCTION This study was designed to assess sex differences in older adults (55-65 years old) in executive functions and to examine the influence of hormone therapy (HT) in postmenopausal women. METHOD We have assessed task performance in memory, visuospatial, and executive functions in 29 women using HT, 29 women who never used HT, and 30 men. RESULTS Men outperformed never users in task switching and updating. HT users outperformed never users in updating. HT users outperformed never users and men in visual divided attention. DISCUSSION The present study support previous findings that sex and HT impact cognition and bring new insights on sex and HT-related differences in executive functions.
