Alzheimer's Disease is a progessive neuro de-generative disorder. In recent years researchers have found that exercise improves memory,concentration, and abstract reasoning among older adults, and may even delay the onset of Alzheimer's disease. Aerobic exercise increases blood flow to the brain which nourishes brain cells and allows them to function more effectively. A recent study showed that exercise actually promotes the growth of new neurons(brain cells) in the hippocampus--the part of the brain that controls memory and learning. Scientists previously believed that once brain cells died, they were not replaced. According to previous research, chemicals, obesity, and smoking have all been linked to Alzheimer's. People who described themselves as goal-oriented and abel to control impulses were less likely to develop Alzheimer's Disease according to a study of 997 people. Baby monkeys exposed to lead showed Alzheimer's like symptoms including amyloid plague, years later, according to a recent study. At the University of Alabama at Birmingham, mice who drank the equivalent of five sodas a day for six months did worse on memory tasks than those who drank water. The mice that had sodas had more than twice the amyloid plaque in their brains (which is a sign of Alzheimer's) than the others.The treatment costs of Alzheimer's Disease(AD) in the United States is estimated to be 100 billion. AD is the fourth common cause of death after heart disease, cancer and stroke. The neurobehavioral hallmark of probable AD is a gradual onset and continuous cognitive decline. The neuropathology of AD can only be confirmed by biopsy or autospy which includes the presence of neurofibillary tangles and amyloid or senile plaques. They occur in normal elderly persons but they occur in much larger numbers throughout the brains of AD patients and affect the functioning of the hippocampi. The brains of AD victims also have large numbers of granulovascuolar organelles which are small clusters of dead brain cell material that collect in the neurons in the hippocampi.
