cerebrospinal fluid (CSF) biomarkers

Cerebrospinal fluid (CSF) biomarkers are specific substances found in the fluid surrounding the brain and spinal cord. They help doctors detect or monitor neurological conditions like Alzheimer’s disease and multiple sclerosis. For example, certain proteins in CSF, such as amyloid-beta and tau, can indicate the presence of Alzheimer’s by revealing abnormal brain changes. Measuring these biomarkers through a lumbar puncture (spinal tap) allows for more accurate diagnosis and understanding of brain health, often before symptoms appear. They are valuable tools in advancing diagnosis and tailoring treatments for neurological disorders.
