Question

What is one way in which older adults compensate for less efficient brain functioning?

Expert Solution

Step 1

As we age, our brain shrinks in volume, particularly the frontal lobe. The risks of strokes increase with the increase in age. The ischaemia develops lesions on our white matter. Decline in memory is also observed as a cause of aging.

Step 2

According to the study performed on human brain mapping, it was discovered that the increased communication between the distant regions of the brain helps in countering the negative aspects of aging. An aged brain has shown bilateral communication happening more than a young brain. Older brains have been found to show increased activation in the hemispheres.
