WebAn important age change is the accumulation of pigments and inert—possibly deleterious—materials within and between cells. The pigment lipofuscin accumulates within cells of the heart, brain, eye, and other tissues. In humans it is not detectable at a young age, but particularly in the heart it increases to make up a small percentage of the cell … WebAlzheimer's Changes the Whole Brain. Alzheimer's disease leads to nerve cell death and tissue loss throughout the brain. Over time, the brain shrinks dramatically, affecting nearly all its functions.
