Question

Quizplus · Accepted Answer

Over the course of a lifetime, the brain will naturally shrink by about 10% due to the loss of neurons and connections between them. This process is called brain atrophy and often begins in early adulthood but accelerates in later years. However, lifestyle factors such as exercise, diet, and cognitive stimulation can help reduce the rate of shrinkage and potentially even promote growth in certain areas of the brain.
