Studies on Alzheimer's Disease

November 25, 2013

As a CNA working for BrightStar Care of Greater Chattanooga, I like to stay updated on current Alzheimer's Disease information in order to give knowledgeable care to our many clients who suffer with Alzheimer's Disease.

Scientists are conducting studies to learn more about plaques, tangles, and other features of Alzheimer’s disease. They can now visualize beta-amyloid associated with plaques by imaging the brains of living individuals. Scientists are also exploring the very earliest steps in the disease process. Findings from these studies will help them understand the causes of Alzheimer’s.

One of the great mysteries of Alzheimer’s disease is why it largely strikes older adults. Research on how the brain changes normally with age is shedding light on this question. For example, scientists are learning how age-related changes in the brain may harm neurons and contribute to Alzheimer’s damage. These age-related changes include atrophy (shrinking) of certain parts of the brain, inflammation, the production of unstable molecules called free radicals, and mitochondrial dysfunction (a breakdown of energy production within a cell).


Thirty years ago, we knew very little about Alzheimer’s disease. Since then, scientists have made important advances. Research supported by NIA and other organizations has expanded knowledge of brain function in healthy older people, identified ways we might lessen normal age-related declines in mental function, and deepened our understanding of the disease. Many scientists and physicians are now working together to untangle the genetic, biological, and environmental factors that, over many years, ultimately result in Alzheimer’s. This effort is bringing us closer to better managing and, ultimately, preventing this devastating disease.
