Alzheimer’s disease is derived from the increase in the buildup of amyloid plaques. Amyloid plaques cause disconnections between nerve cells. The disconnections can alter and affect a person’s thinking, memory and behavior. Deep brain stimulation was attempted to see if it would help with Alzheimer's. The devices were implanted into the fornix, which is a fiber bundle between the hippocampus and hypothalamus. The use of deep brain stimulation increased glucose metabolism. After the testing, it was found that the increase in glucose metabolism had no effect on the disease. Therefore, the use of deep brain stimulation was not a good option as an alternative.
