CSF and blood neuronal injury biomarkers in spinal bulbar muscular atrophy and amyotrophic lateral sclerosis 4.

ABSTRACT: Spinal and bulbar muscular atrophy (SBMA) and amyotrophic lateral sclerosis 4 (ALS4) are two forms of motor neuron disease characterized by clinically slow disease progression. Based on the current limited human studies, the contribution of central nervous neurodegeneration to these diseases and the rate of clinical progression is unclear. Neuronal proteins glial fibrillary acidic protein (GFAP), neurofilament light (NfL) chain, or Total-tau measured in either cerebrospinal fluid or blood could serve as sensitive markers of neurodegeneration. We studied 56 adult participants (32 SBMA, 7 ALS4, and 17 controls) who were enrolled at the National Institutes of Health, of whom 22 (10 SBMA, 7 ALS4, and 5 controls) underwent paired CSF and serum sampling, and of whom 6 participants were assessed
