Association Between Androgen Deprivation Therapy For Prostate Cancer And Alzheimer's Disease, Gina Giannantoni-Ibelli

Walden Dissertations and Doctoral Studies

Alzheimer's disease (AD) is the most common progressive, neurodegenerative disease and form of dementia. The hallmarks of AD are extracellular accumulation of amyloid beta protein, resulting in neuritic, senile plaques and intracellular accumulation of tau protein. AD mainly arises from imbalance of amyloid beta protein production and its clearance in the brain. Testosterone modulates production of amyloid beta protein by decreasing its accumulation. Prostate cancer remains a substantial public health challenge in the United States. While androgen deprivation therapy (ADT) is an effective treatment for prostate cancer, it may be associated with cognitive impairment due to decreased levels of testosterone. …
