Protective actions of sex steroid hormones in Alzheimer’s disease

By Christian J. Pike, Jenna C. Carroll, Emily R. Rosario, and Anna Barron

Risk for Alzheimer’s disease (AD) is associated with age-related loss of sex steroid hormones in both women and men. In postmenopausal women, the precipitous depletion of estrogens and progestogens is hypothesized to increase susceptibility to AD pathogenesis, a concept largely supported by epidemiological evidence but refuted by some clinical findings. Experimental evidence suggests that estrogens have numerous neuroprotective actions relevant to prevention of AD, in particular promotion of neuron viability and reduction of β-amyloid accumulation, a critical factor in the initiation and progression of AD...
