A. Alzheimer- The Brain Disorder: Just like the rest of our bodies, our brains change as we age.
Most of us notice some slowed thinking and occasional problems remembering certain things.
However, serious memory loss, confusion and other major changes in the way our minds work
are not a normal part of aging [6]. These may be the signs of brain cells failure [7].
The brain has 100 billion nerve cells (neurons). Each nerve cell communicates with many others
to form network. Nerve cell networks have special jobs. Some are involved in thinking, learning
and remembering. Others help us see, hear and smell. Still others tell our muscles when to move.
In Alzheimer’s disease, as in other types of dementia, increasing numbers of brain cells
deteriorate and die [6]. Figure 3 shows the gradual increase of Alzheimer’s diseased people
