Dementia Biomarkers
Dementia biomarkers are measurable indicators that help in the diagnosis and monitoring of dementia, a group of brain disorders that cause a long-term and often gradual decrease in cognitive impairment. These biomarkers can be detected through various means, such as brain imaging tests (like MRI and PET scans), cerebrospinal fluid analysis, and blood tests. They primarily focus on identifying changes in the brain and body fluids that are associated with the development and progression of dementia-related diseases, such as Alzheimer’s disease. Key biomarkers include the levels of tau and beta-amyloid proteins, which are known to be present in brains of Alzheimer’s patients. The early detection of these biomarkers can lead to more timely and effective interventions, improving the management of the disease and potentially slowing its progression.
