MedicalResearch.com: What is the background for this study?
Response: Aromatase inhibitors (AIs) including letrozole are given as an adjuvant therapy for postmenopausal women with hormone receptor positive breast cancer. Women taking this drug have reported a number of symptoms including hot flashes, memory complaints and mood changes. However, not all studies report memory issues. This might be due to the fact that studies in this population are hampered by confounds, such as chemotherapy/radiotherapy, stress and disease stage, all of which can also adversely impact memory. These confounds make it challenging to observe the independent effects of AIs on memory. By using a non-human primate model, we were able to examine the effects of aromatase inhibition on these symptoms as well as brain function without these confounding effects.
