Although research clearly demonstrates that chronically elevated cortisol (from disease, corticosteroid treatment, or aging) is associated with impairments in declarative memory (Lupien et al., 2004, 1998; Martignoni et al., 1992), evidence for acute effects is mixed. Early experimental studies using stress induction or single-dose glucocorticoid administration showed an impairing effect of acutely elevated cortisol on verbal declarative memory (Kirschbaum et al., 1996; Newcomer et al., 1994; Wolf et al., 2001; Wolkowitz et al., 1990). However, recent studies investigating acute effects of cortisol on word recall either failed to replicate these findings by using cortisol administration (Hsu et al., 2003) or psychosocial stress (Wolf et al., 2001) or obtained opposite findings (Domes et al., 2002).

One explanation for these discrepancies, according to Beckner and colleagues (2006), may be due to differences in dose levels of glucocorticoids. Both animal and human data suggest an inverted U-shaped function between glucocorticoids and memory (see Lupien & McEwen, 1997, for a review).

Although research clearly demonstrates that chronically elevated cortisol (from disease, corticosteroid treatment, or aging) is associated with impairments in declarative memory (Lupien et al., 1998; Martignoni et al., 1992; Starkman & Schteingart, 1981; Wolkowitz, Lupien, Bigler, Levin, & Canick, 2004), evidence for acute effects is mixed. Early experimental studies using a stress induction or single-dose glucocorticoid administration showed an impairing effect of acutely elevated cortisol on verbal declarative memory (Kirschbaum, Wolf, May, Wippich, & Hellhammer, 1996; Newcomer, Craft, Hershey, Askins, & Bardgett, 1994; Wolf, Schommer, Hellhammer, McEwen, & Kirschbaum, 2001; Wolkowitz et al., 1990).
