What Is the Difference Between a Normal Brain and an Alzheimer's Brain?
The main manifestations of Alzheimer's disease are forgetfulness, sluggish eyesight, sluggish speech, which in turn affects the sensory nerves and loses their ability to take care of themselves. It has become a major nemesis in the health of the elderly. According to World Health Organization estimates, 5% of the world's elderly people over 65 years old have Alzheimer's disease. Epidemiological surveys abroad found that Alzheimer's is the fourth leading cause of death among the elderly after cardiovascular disease, cerebrovascular disease and malignant tumors. Some people predict that dementia will be the most terrible geriatric disease in the next century.
