Some say I know that Alzheimer’s affects the brain but how? Does it differ in men and women? Each time an individual is diagnosed with Alzheimer’s, their brain begins to shrink. A healthy brain is a pink color, but when someone develops Alzheimer’s their brain turns a blackish gray color. However, color is not the only thing that happens to the brain when diagnosed.
There are many parts of the brain and many of those parts are affected. Some examples of those are the cortex, plaques, nerves, ventricles, and hippocampus, to name a few. First, I will elaborate a little bit on the cortex. The cortex is the largest part of the brain, and it controls more important things. This is where thinking, planning, and remembering takes places. The reason all of memory goes first because the cortex shrinks first.
Not all of the brain shrinks, however. Ventricles are fluid filled holes in the brain. Ventricles work with communication. This part of the brain swells. When the ventricles swell, the communication of the body with the brain is slowed down greatly.
The biggest problem people face when their brain shrinks is the hippocampus shrinking. The hippocampus controls the making of new memories. That is why when people get Alzheimer's they forget everything. Sometimes people act like a child or refer to their childhood when they have had this disease for a few years. When the hippocampus shrinks it is the cause of most problems people face.
