Your Diagnosis is Probably* Right

The asterisk that changes everything: Why symptom-based diagnosis in neurodegenerative disease leaves too much room for doubt.

When 'Probable'
Becomes Personal

Every "probable" diagnosis starts a clock—one that keeps ticking while patients and families wait for answers. In neurodegenerative disease, probability isn't just a word—it's a burden carried by patients, families, and physicians alike.

  • The average patient receives 2-3 different diagnoses before their journey ends
  • Families spend years adjusting to changing prognoses
  • Critical time is lost while waiting for symptom progression
  • Treatment plans require constant revision as symptoms evolve

What Symptoms Can't Tell You

What you see isn't always what you get. The challenge isn't just about uncertain diagnoses—it's about the complex reality of neurodegenerative disease that symptoms alone can't reveal.

30-50%

Clinically diagnosed Alzheimer's patients who have Lewy body pathology at autopsy

70%

Parkinson's and LBD patients who have mixed pathologies

50%

Cognitive disorder patients with mixed pathologies at autopsy

30%

Clinically diagnosed Parkinson's and DLB patients that do not have Lewy body pathology at autopsy

When diagnosis is based on presuming, every medical decision carries that same uncertainty forward.

  • Risk of contraindicated medications being prescribed
  • Higher rates of hospitalization from incorrect treatment
  • Missed opportunity to prescribe drugs that will improve quality of life
  • Inefficient use of healthcare resources

We are the next step in a technological breakthrough that allows us to see a whole family of diseases that couldn't be approached before. And that approach will allow us to have significant impact and to develop tools, drugs, other diagnostics to change these diseases and improve the lives of many people
