Estrogen receptor-alpha gene XbaI A > G polymorphism influences short-term cognitive decline in healthy oldest-old individuals
ABSTRACT This prospective study aimed to evaluate the influence of the -351A/G XbaI polymorphism in the estrogen receptor-alpha (ESR-1) gene on global cognitive scores of a community sample of healthy oldest-old individuals within one year of follow up. Methods The individuals were categorized in...
