HMM: Prostate Cancer Treatment Tied to Alzheimer’s Risk. “Hormone therapy, a common treatment for prostate cancer, is associated with an increased risk for Alzheimer’s disease, a new study has found. The goal of hormone therapy, also known as androgen deprivation therapy, is to lower the level of male sex hormones, or androgens, that stimulate the growth of prostate cancer cells. Over all, those treated with hormone therapy had an 88 percent increased risk of Alzheimer’s compared with other patients. The longer the hormone treatment, the more the risk increased, and patients with at least 12 months of treatment had more than double the risk. . . . Androgens have been shown to affect the accumulation of amyloid plaques, one of the features of Alzheimer’s disease, and this may be one mechanism that could explain the finding.”

I wonder if this means that testosterone supplementation might reduce the risk of Alzheimer’s?
