Although we still don’t know how Alzheimer’s disease begins, it seems likely that damage to the brain starts years before problems become obvious. During the earliest stage of Alzheimer’s, people are free of symptoms, but harmful changes are taking place in the brain. Abnormal protein deposits form amyloid plaques and neurofibrillary tangles in the brain. Once-healthy nerve cells lose their ability to function and communicate with each other, and eventually they die. An early diagnosis is critical to maintaining your quality of life, so be sure you know the early warning signs of Alzheimer's disease.
