Amyloid beta is a type of protein that is produced in the brain and is associated with the development of Alzheimer's disease. Research in this area focuses on understanding how amyloid beta proteins are produced, how they accumulate in the brain, and their role in the development of cognitive decline and other symptoms of Alzheimer's disease. Scientists are also investigating potential treatments and therapies that target amyloid beta to slow or prevent the progression of Alzheimer's disease.
