The Power to Get It Right

Move Beyond Suspicion to Precision

Even the best clinical diagnosis for neurodegenerative disorders is wrong 33-44% of the time.



SAAmplify-αSYN is the first clinically available, validated test that detects pathological α-synuclein with autopsy-confirmed accuracy—bringing unprecedented biological clarity to the diagnosis of diseases like Parkinson’s, Lewy body dementia, and Alzheimer’s.

The Limitations of Yesterday

Traditional Diagnosis: Informed Decision
  • Treatment decisions based on "probable" diagnosis
  • 2-3 years average time in diagnostic odyssey
  • Clinical diagnosis contradicted by autopsy in up to 30% of cases
  • Up to 50% of Alzheimer's patients also have Lewy body pathology
  • Most neurodegenerative disorders involve mixed pathologies, not single diseases

For decades, physicians have been forced to diagnose based on symptoms, missing the complex reality of mixed pathologies that define most neurodegenerative disorders.

The Certainty of Today

SAAmplify-ɑSYN: Biological Clarity
  • Only validated test for detecting misfolded α-synuclein in CSF
  • Used in over 20,000 samples to date
  • Autopsy-confirmed accuracy
  • Treatment decisions guided by biological evidence

SAAmplify-ɑSYN reveals what symptoms can't tell you – the actual biology driving neurodegenerative disease.

We have the real possibility to impact the life of millions and millions of people if we can identify the disease before it damages the brain.
