Get a plasma P-tau 217 blood test now — it detects Alzheimer's pathology up to 20 years before symptoms with 95–97% accuracy, giving you the longest possible prevention window.

Key takeaways

Two new drugs slow Alzheimer's progression 27–36% — first ever in 30 years of trials

Two new drugs slow Alzheimer's progression 27–36% — first ever in 30 years of trials

  • Lecanemab (2023) slowed cognitive decline 27% vs placebo; Donanemab (2024) showed 29–36% slower clinical progression.
  • Context: 99.6% of prior Alzheimer's drugs failed in clinical trials with zero effect on disease progression.

Blood test predicts Alzheimer's 20+ years early with 95-97% accuracy

  • Plasma p-tau 217 achieves AUC 0.95–0.97 for predicting amyloid positivity; FDA approved first blood-based test in 2025.
  • Previously required $5,000+ PET scan or spinal tap; p-tau 217 is now available in labs worldwide.

Chronic sleep under 6 hours actively accumulates amyloid and tau in the brain

  • Glymphatic clearance of amyloid runs primarily during slow-wave sleep; circadian misalignment further impairs it.
  • Sleep deprivation raises both amyloid-beta and tau protein levels — not just next-day cognitive impairment.
