Question

changes in the central nervous system that accompany aging include all of the following except
changes in synaptic organization in the brain.
decrease in the number of neurons.
decreased blood flow to the brain.
reduction in brain size and weight.
decreased lipofuscin accumulation.

Explanation:

Lipofuscin is a pigment that accumulates in cells with age. In the central nervous system, aging is associated with an increase, not a decrease, in lipofuscin accumulation. Changes in synaptic organization, a decrease in neuron number, reduced blood flow to the brain, and a reduction in brain size and weight are all well - documented age - related changes in the central nervous system.

Answer:

decreased lipofuscin accumulation.
