0564 NS 25 Notes a Pearson’s correlation coefficient. NS=not significant. Multiple step regression analysis revealed that neither DHEA nor DHEAS affect the potency or the significance of the correlation between CDRS/anxiety and 3-ADIOL. DHEA plasma levels in the asymptomatic group may appear at odds with an action of DHEA in brain as positive allosteric modulator of the ionotropic glutamate receptor of the NMDA type (Paul and Purdy, 1992; Compagnone and Mellon, 1998) or as negative modulator of GABAA receptors (Imamura and Prasad, 1998), mechanisms through which DHEA should, eventually, yield anxiety (Haefely, 1994; Wiley, 1997).

Of course, it cannot be ruled out the possibility that DHEA may act through multiple and, perhaps, as yet undiscovered mechanism(s) of action and it is possible that menopause or age-related changes in GABAA receptor structure and function may take part in the expression of anxiety. , 1994). , 2000), the lower DHEA and 3-ADIOL concentrations found in symptomatic women may be a consequence of their anxiety symptomatology. These results, although obtained in a limited number of subjects, on one side suggest that differences in the plasma concentrations of 3-ADIOL, one of the GABAA receptor active metabolites of DHEA, may indeed reflect a different availability of this neuroactive steroid also in brain, on the other side may lead to surmise that DHEA supplementation may be useful, at least to control the menopause-related anxiety symptomatology.
