Hormone therapy for prostate cancer can affect men's thinking

Androgen-deprivation therapy (AD), an effective therapy in the treatment of prostate cancer reduces levels of testosterone (a tumor stimulant), and estradiol, a form of estrogen, in men. These are known to be important in neurological development and play a particularly important role in the cognitive areas of learning and memory.
