Parkinson’s disease (PD) remains a challenging neurodegenerative disorder to diagnose and monitor.
Conventional clinical assessments and imaging often miss early molecular events, while overlapping symptoms with other synucleinopathies complicate diagnosis.
Alpha synuclein seed amplification assays (SAAs), including RT-QuIC, have emerged as diagnostic tools, detecting trace amounts of pathogenic aggregates with sensitivity and specificity.
These assays exploit the prion-like seeding behavior of misfolded alpha synuclein, enabling earlier and more accurate identification of disease-associated seeds.
By exploiting the prion-like seeding behavior of misfolded alpha synuclein, these assays detect trace amounts of pathogenic aggregates with exceptional sensitivity and specificity.
