To the Editor: Dr Zandi and colleagues1 argue that underreporting of HRT use among women
who subsequently develop AD is unlikely because of the "notable nature of
a decision to use HRT and the tendency of women to use HRT for an extended
period of time." Furthermore, the authors note no relationships between "control
exposures" (ie, calcium and multivitamins) and the incidence of AD. The authors
conclude it is unlikely that women who later developed dementia would have
selectively forgotten making a "carefully considered decision to use HRT."
