CSF biomarkers

CSF (cerebrospinal fluid) biomarkers are specific substances measured in the fluid surrounding the brain and spinal cord. These markers help doctors identify and monitor neurological conditions like Alzheimer's disease by detecting characteristic changes. For example, certain proteins like beta-amyloid and tau levels are measured because their patterns differ in healthy individuals versus those with neurodegenerative diseases. Analyzing CSF biomarkers provides valuable clues about brain health, disease presence, and progression, supporting more accurate diagnoses and guiding treatment decisions.
