Reuters Health (Internet) 3/13/06 In men with prostate cancer undergoing androgen deprivation therapy, most of the symptoms known collectively as “androgen deprivation syndrome” are likely due to the fact that the patients are older, sicker and have more advanced disease, a new study shows. While some health effects of androgen deprivation therapy are clearcut – for example sexual dysfunction – “there's this whole set of sort of less specific, more vague symptoms, like changes in mood, memory, feeling unwell, being tired,” Dr. Vahakn B. Shahinian of the University of Texas Medical Branch at Galveston told Reuters Health.
