Tau Levels in Spinal Fluid Possible Biomarker of ALS, Likely Progression
Levels of the protein tau found in the cerebrospinal fluid (CSF) — the transparent liquid surrounding the brain and spinal cord — can help in diagnosing amyotrophic lateral sclerosis (ALS), a study reported. Tau levels in ALS patients also correlated with a faster progression rate and poorer survival, suggesting this…
