Alzheimer’s Disease and the Brain
Here is another view of how massive cell loss changes the whole brain in advanced Alzheimer’s disease. This slide shows a crosswise “slice” through the middle of the brain between the ears.
In the Alzheimer brain:
- The cortex shrivels up, damaging areas involved in thinking, planning and remembering.
- Shrinkage is especially severe in the hippocampus, an area of the cortex that plays a key role in formation of new memories.
- Ventricles (fluid-filled spaces within the brain) grow larger.
