Specific biomarkers for the brain
In addition to the general markers for brain function mentioned above, there are certain biomarkers that are more specific to the brain like:
- tau protein
- amyloid beta and
- neurofilament light
Tau (similar in structure to an entangled rope that can be observed in a microscope) protein and amyloid beta have been linked to Alzheimer´s disease for quite some years without showing convincing causal relationship to these proteins in intervention studies. Nevertheless, tau protein and amyloid beta are used as diagnostic criteria to Alzheimer`s disease.
