Alzheimer's Disease
OpenStop neurodegeneration before memory loss, and preserve cognition in people already affected.
What “cured” would have to mean
Halted cognitive decline with resolved amyloid and tau pathology, or prevention of clinical onset in people with biomarker evidence.
This is the bar the work aims at. Nothing on this page claims it has been reached.

Readiness gates
- PASSG1 Program status is current. 0 overdue status entries and 0 unflagged inactive mentions in the neurology dossier.
- PASSG2 At least 10 verified sources. 11 of 11 seed papers resolved in PubMed.
- PASSG3 Trials mapped to tracks. 1670 of 1774 trials (94.1%) fall in a track (needs 90%); 29.1% sit only in the not-yet-classified track (needs 30% or less).
- PASSG4 Outcome ladder defined. 6 rungs, 4 counted automatically from registered outcomes.
- PASSG5 Contribution work exists. 461 completed trials past 18 months with no posted results (results-gap queue).
- PASSG6 Copy is honest. No cure claims and no em dashes in module text.
Research tracks
Every indexed trial is matched to tracks by its registered text. A trial can sit in several tracks; 517 (29.1%) are not yet classified.

Outcome ladder
Research categories from first signal to the cure bar. Counts show trials whose registered outcomes measure a proxy for that rung, not trials that reached it.
- 1Symptom relief. Better cognition or behavior while disease continues.574 measuring
- 2Pathology reduced. Amyloid or tau burden reduced on imaging or fluid biomarkers.328 measuring
- 3Decline slowed. Slower clinical decline versus control on a global scale.246 measuring
- 4Onset delayed. Delay of symptomatic onset in biomarker-positive people.100 measuring
- 5Durable remission candidate. Halted decline with resolved pathology sustained over long documented follow-up with acceptable safety.not counted
- 6Biological cure. Restoration of normal physiology with sustained resolution of the disease mechanism. Requires especially rigorous evidence; nothing here claims it.not counted
