Anyone who says animal research provides no human benefit is blinded by ideology. Research in mice has opened a potentially productive way forward for an Alzheimer’s treatment. From the Independent story:
Scientists have hailed an historic “turning point” in the search for a medicine that could beat Alzheimer’s disease, after a drug-like compound was used to halt brain cell death in mice for the first time
Although the prospect of a pill for Alzheimer’s remains a long way off, the landmark British study provides a major new pathway for future drug treatments.
Or, we could just euthanize Alzheimer’s patients. Think of the money we could save!
