Quizplus · Accepted Answer

All of the answers are correct. Aging is associated with a host of structural, functional, and biochemical changes in the central nervous system. These include a reduction in brain size and weight, a decrease in the number of neurons, altered synaptic organization in the brain, and reduced blood flow to the brain. These changes can lead to cognitive decline and increased risk of neurodegenerative diseases.
