Parkinson’sdisease(PD)
TheROCcurvebelowshowsthatNF-light(redline)candifferentiateatypicalParkinsonsyndromes,suchasProgressivesupranuclearpalsy(PSP),Multiplesystematrophy(MSA)andCorticobasaldegeneration(CBD),fromParkinson’sdisease(PD)withhighsensitivity.
Multiplesclerosis(MS)
TheROCcurvebelowshowsthatNF-light(redline)hasasignificantlybetterdiscriminatorypowerthantheNF-heavychaintodiagnoseClinicallyisolatedsyndrome(CIS)andanyotherMS-subtype.
Amyotrophiclateralsclerosis(ALS)
