Brain changes that can eventually lead to dementia may begin many years before anyone notices symptoms such as memory problems, missed appointments or difficulty finding words.
This is where blood biomarkers are becoming important. Biomarkers are measurable signs of biological activity in the body. In dementia research, some blood biomarkers can give clues about biological processes related to brain changes. These can include Alzheimer’s-related protein alterations, damage to nerve cells or changes in cells that support and protect nerve cells.
