[Effect of lysine-vasopressin on the Flicker Test and the Buschke Memory Test in elderly patients].

In the present study, we have tested the cortical arousal (Flicker's Test) and mnesic function (Buschke Test) before and after a short-term Lysine-Vasopressin (LVP) treatment in normal senescent male (Age: 64,3 +/- 3,4). We have not been able to evidence any objective nor subjective improvement in the LVP versus placebo treated group. We do not know the origins of the discrepancies between the different clinical studies published so far concerning the influence of exogenous vasopressin on memory in man.
