Crowds are reported as being amazed at a series of anatomical Body Worlds exhibitions being shown at three different location around the world. The 'bodies' are real human bodies 'preserved through a new process call "plastination" where technicians remove the water from organs or whole bodies and replace it with silicon.' Of particular interest is the display of two preserved brains, placed side by side. One healthy brain and one with the effects of full-blown Alzheimer's disease.
One can clearly see the vast difference between the two, with the diseased brain showing the pronounced tissue loss due to nerve cell desruction and general shrinkage. Widespread cell death causes the brain to shrink. Individuals with the disease no longer recognize family and friends. They also lose their ability to care for themselves and communicate.
This severe stage of Alzheimer’s can last anything from one to five years. Most of the brain’s outer layer, which scientists have mapped to memory, movement, thinking and other functions, has been permanently damaged.
Most experts in this field agree that there is a link between Alzheimer's disease and the build up of plaques between nerve cells in the brain. These 'clog' the cells and affect the learning, memory, planning and thinking part of the brain.
The Body Worlds exhibition has a wide range of exhibits, some os which can be seen on their website https://bodyworlds.com/exhibitions/ along with downloadable overviews on the exhibits. These make a useful guide for students and families alike.
