What Is Alzheimer's Disease?
2. What Physical Changes Occur to Cause Alzheimer’s Disease?
Alzheimer’s disease results from physical and chemical changes occurring in the brain. Researchers believe they may begin to take place 10 years or more before symptoms develop.
The changes taking place in the brain revolve around an abnormal buildup of protein deposits. These buildups form collections of protein plaque and tangles or clumps between the brain’s nerve cells. Researchers believe they do more than interfere with the brain’s functioning; they may also cause brain cells to die.
