Effects of stress throughout the lifespan on the brain, behaviour and cognition
In this Review a model is developed to explain why different disorders emerge in individuals exposed to stress at different times in their lives.

Performing mental arithmetic was linked to activation of motor and visual association cortices, as well as brain structures involved in the performance of these tasks (e.g., the angular gyrus).

Cortisol levels during human aging predict hippocampal atrophy and memory deficits
It is demonstrated that aged humans with significant prolonged cortisol elevations showed reduced hippocampal volume and deficits in hippocampus-dependent memory tasks compared to normal-cortisol controls, and the degree of hippocampal atrophy correlated strongly with both the degree and current basal cortisol levels.

The results show that the cortisol response to anticipation of stress and to stress in the elderly specifically affects those memory functions that are dependent on hippocampal activity, and suggest that an altered cortisol responsivity to acute and/or chronic stress, with its detrimental effects on memory, could be an important factor explaining the genesis of memory deficits in aged populations.
