They will become extinct over time. This is because they
will be unable to survive in the changed environment due to lack of desirable traits. This is especially true for a small population of
species that do not have a wide variation in their genotypes on which natural selection
could act upon.

From studies, cortisol was found to have effect on the hippocampus when present in high levels. It damage and kill the cells in that area of the brain. The hippocampus is the area of the brain that is responsible for the long term memory storage. So, when this part is damage then the storage for our memories would surely be affected.
