The Patient

1901 to 1906, and the century since • In June 2026 a team at Monash University reported in ACS Chemical Neuroscience that the copper compound Cu(ATSM) takes a different approach from the failed drugs: rather than blocking amyloid production, it repairs the weakened P-glycoprotein pump at the blood-brain barrier, restoring the brain's own ability to clear amyloid. In mice bred to develop Alzheimer's, it reduced toxic amyloid-beta by about 42 percent and improved spatial learning by about 44 percent over roughly eight weeks, and may also activate microglia to degrade plaques. Two features make it notable: Cu(ATSM) has already passed human safety trials for Parkinson's disease and ALS (a potential fast track), and the strategy of restoring clearance is closer to the actual failure Alzheimer saw than a century of attempts to block production. The crucial caveat is that this is preclinical, in mice, and the history of Alzheimer's research is full of compounds that dazzled in mice and failed in humans, so it is a genuinely new mechanism and a reason for measured hope, not a cure. •

Lesson plan: The Patient Who Lost Herself

A classroom companion to the Time Rhymes story of Alzheimer's disease, from Alois Alzheimer and Auguste Deter in 1906 to the June 2026 copper compound that restored the brain's ability to clear amyloid in mice.

Suitable for: secondary biology and introductory undergraduate (ages 16 and up). Time: one 50 to 60 minute lesson.

Learning objectives

By the end, students should be able to:

  1. Describe how Alzheimer identified the disease in 1906 from Auguste Deter's case and brain.
  1. Name the two defining pathologies of Alzheimer's: amyloid plaques and tau tangles.
  1. Explain the difference between blocking production of a toxin and clearing it, and why both matter.
  1. Describe the role of the blood-brain barrier and its efflux pump in clearing waste from the brain.
  1. Critically interpret a promising preclinical (mouse) result and explain why it is not yet a cure.

Key concepts

  • Alzheimer's disease: a progressive neurodegenerative disease defined by amyloid plaques and tau tangles.
  • Amyloid-beta: a protein that aggregates into plaques outside neurons.
  • Tau: a protein that forms tangles inside neurons.
  • Blood-brain barrier: the selective wall between blood and brain tissue.
  • P-glycoprotein (P-gp): an efflux pump that helps flush waste, including amyloid, out of the brain.
  • Production versus clearance: a buildup can come from making too much or removing too little.
  • Preclinical research: studies in cells and animals that precede human trials.

Lesson flow

  1. Hook (5 min): "I have lost myself." Auguste Deter's line and the limits of 1906 medicine.
  1. The discovery (10 min): Alzheimer's 1906 autopsy, plaques and tangles, and how the same two features still define the disease.
  1. A century of failure (10 min): why drug after drug aimed at amyloid disappointed, and what "the amyloid hypothesis" means.
  1. The clogged drain (12 min): the blood-brain barrier and the P-gp pump; reframing the problem as failed clearance rather than only overproduction.
  1. The 2026 result (13 min): Cu(ATSM) repairing the pump, the mouse numbers (about 42 percent less amyloid, about 44 percent better memory), and the head start of prior human safety testing.
  1. Reading the result honestly (10 min): mice versus humans, the graveyard of failed Alzheimer's drugs, and what would have to happen next.

Discussion questions

  • The new approach helps the brain clean itself rather than stopping it dirtying itself. Why might that be a better match to the underlying problem?
  • A 42 percent reduction in mice sounds dramatic. What specific questions would you want answered before believing it will help patients?
  • Cu(ATSM) was already safety-tested for other diseases. How does drug repurposing change the speed and risk of getting a treatment to people?

Quick activity

Give students a simple 'bathtub' model: water in (production) and a drain (clearance). Have them reason about how the level rises if the drain narrows even when the tap stays the same, then map the tap to amyloid production and the drain to the P-gp pump, and predict what fixing each would do.

Glossary

  • Plaque: an extracellular clump of aggregated amyloid-beta.
  • Tangle: an intracellular twist of tau protein.
  • Efflux pump: a protein that transports substances out of a cell or compartment.
  • Microglia: the brain's resident immune and cleanup cells.
  • Preclinical: research conducted before human clinical trials.
