Abstract: Does stress have a negative impact on memory during human aging and
which role is played by the Hypothalamus-Pituitary-Adrenal (HPA) axis? The
present review tries to answer this question by summarizing specific age
associated changes of the HPA axis. These are associated with declarative
memory impairments. Whether these impairments reflect structural changes
(hippocampal atrophy) or rather acute reversible phenomena is incompletely
investigated. In addition a better explanation for the large interindividual
variance is needed. In this field genetic approaches as well as an increased
attention to local steroid metabolism are very promising. An enhanced
understanding of the effects of stress on the aging brain will lead to a more
targeted and more efficient prevention and therapy of age associated memory
deficits.
