MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Previous studies have shown an association between androgen deprivation therapy (ADT) and risk of dementia and Alzheimer’s disease. However, these studies had methodological limitations that may account for this positive association. Using appropriate study design and methodology, we found no association between androgen deprivation therapy and risk of dementia (including Alzheimer’s disease) in patients with prostate cancer. These results were consistent by cumulative duration of  androgen deprivation therapy use and by ADT modality.

MedicalResearch.com: What should readers take away from your report?

Response: This study shows that there is no association between androgen deprivation therapy and dementia in patients with prostate cancer. Thus, this study provides reassurance to patients with prostate cancer regarding this potential adverse event.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: Patients who are diagnosed with prostate cancer are an older patient population and thus at increased risk of dementia. This study should provide these patients with reassurance that  androgen deprivation therapy does not cause dementia. Additional studies in different settings are needed to confirm these findings.
