The steroid pregnenolone sulfate (PREGS) may be one of the factors responsible for the memory decline related to normal aging or associated with Alzheimer's disease (AD). The purpose of this study is to determine whether plasma levels of PREGS are decreased patients with at mild to moderate AD compared with AD-free control subjects matched for gender and age and to see whether they are inversely correlated with the severity of memory deficits in AD patients. The hypothesis is that blood levels of PREGS are decreased with advanced age and with the stage of AD that would be positively correlated with memory deficits. Therefore PREGS could be considered as an early marker of the memory deficits in AD.
