Objective
Several evidences implicate that monoamines play a modulatory role in the brain mechanisms underlying encoding and retrieval
of emotional memories. Recent experiments demonstrate that acute monoaminergic potentiation with the antidepressants bupropion
or sertraline enhance the retrieval of longterm emotional memory in rodents. In the present study, we tested the hypothesis
that acute monoaminergic re–uptake inhibition with these antidepressants might enhance retrieval of emotional memory in man.
Methods
The central monoaminergic system was stimulated with either bupropion or sertraline in a doubleblind, randomized, placebo–controlled
design with 105 healthy adult subjects divided in three groups (placebo, 150 mg–bupropion and 50 mg–sertraline). Memory was
evaluated with a ‘surprise’ memory test 7 days after the presentation of an emotional story and with a wordcued autobiographical
memory test.
Results
A total of 99 volunteers completed the experimental procedures. Contrasting to our prediction, we found no memory enhancing
effect for either drug in both memory tests. All groups showed the expected heightened memory performance to the middle ‘emotive’phase
of the story.
Conclusion
Stimulation of the central monoaminergic system with the antidepressants bupropion and sertraline did not enhance the retrieval
of long–term emotional memories in man.
