These clumps of a protein called beta-amyloid may damage and destroy brain cells in several ways, including interfering with cell-to-cell communication. Brain cells depend on an internal support and transport system to carry nutrients and other essential materials throughout their long extensions. This system requires the normal structure and functioning of a protein called tau. This failure is also strongly implicated in the decline and death of brain cells.

As a result, sufferers in these late stages usually are incontinent and begin to lose a lot of weight. They often spend most of their time sleeping, and frequently suffer from seizures. Our increased understanding of biology and the human genetic code have many scientists hopeful for effective preventive measures and possibly even cures in the near future.

Already, there are results from a number of recent studies that suggest that certain life behaviors, such as a healthy diet and regular exercise, can help reduce your chances of developing the disease.
