Abstract
As neurons die cholesterol is released in the central nervous system (CNS), hence this sterol and its metabolites may represent a biomarker of neurodegeneration, including in amyotrophic lateral sclerosis (ALS) in which altered cholesterol levels have been linked to prognosis. More than 40 different...
