A positron emission tomography (PET) scan showing a transverse section of a brain affected by Alzheimer's disease. Red areas on the scan represent high levels of amyloid, which is a protein that is associated with Alzheimer's disease. Blue areas indicate no amyloid. Beta-amyloid molecules can accumulate in the brain and create beta-amyloid plaques. These plaques form around nerve cells in the hippocampus, causing nerve cell death and negatively effecting memory, cognition, and decision-making skills. This process is known to be a significant cause or symptom of Alzheimer's disease. | |
