Summary
The alpha-synuclein seed amplification assay (αSyn-SAA) test has been validated as a highly accurate biological test for Parkinson’s disease, according to researchers at the Parkinson’s Progression Markers Initiative (PPMI). The test can identify synuclein pathology, detecting disease before cardinal movement symptoms occur. It can differentiate molecular subtypes and improve clinical trial design, leading to earlier intervention and personalised treatment options.

Fact

🧬 The alpha-synuclein seed amplification assay (αSyn-SAA) test has been validated by leaders of the Parkinson’s Progression Markers Initiative (PPMI).

🧑‍🔬 The test has a greater than 90% sensitivity for typical Parkinson’s pathology and is frequently positive even before the onset of symptoms.

🧠 The test detects synuclein pathology, one of the two biological hallmarks of Parkinson’s disease, offering a critical tool for clinical trial design and early detection of disease pathology.

👨‍⚕️ The test’s ability to differentiate molecular subtypes and detect disease in individuals before cardinal movement symptoms arise provides a novel tool for precision medicine approaches.

💊 This breakthrough opens up new avenues for earlier intervention and improved clinical trial design, leading to personalised treatment options and potentially a cure for Parkinson’s disease.
