> Breakthrough in Parkinson's research with new diagnostic test (WIRED)
> The Michael J. Fox Foundation's breakthrough in Parkinson's disease research introduces the "alpha-synuclein seeding amplification assay" (SAA), a test capable of detecting misfolded alpha-synuclein in spinal fluid with 90% specificity. It identifies PD pathology before symptoms emerge, revolutionizing early diagnosis and drug trials. A scratch-and-sniff test, linked to neurodegeneration, aids in identifying at-risk individuals. The SAA accurately diagnosed 99% of people with poor smell and sporadic Parkinson's. This development will transform Parkinson's research and care.
