Amyloid plaques, neurofibrillary tangles, and neurons, being the loss of connection between nerve cells, are the main features in Alzheimer’s disease. Abnormal deposits of protein form amyloid plaques and tangles throughout the brain and the at once healthy brain begins to work less efficiently. Over this time, neurons then lose the ability to function and communicate with each other and they eventually end up dying. The damage caused by this soon spreads to a near structure in the brain called Hippocampus. Hippocampus plays important roles in the the brain such as long-term memory. As more and more neurons tend to die, the affected parts of the brain begin to shrink.
