A Fatal Nerve Disease and the Quest for Treatment | Dr. João Pereira

About this episode

What does it take to study a fatal motor neuron disease with no cure?
In this episode of Why Research Matters, Varunika Goyal speaks with Dr. João Pereira, a neuroscientist at the University of Alabama at Birmingham, about ALS, neurodegeneration, and the race to change the future of this devastating disease.
Dr. Pereira explains why ALS is so difficult to diagnose and treat, how patient-derived stem cells and organoids help researchers model human disease, why animal models still matter, and how new tools like AI, imaging, and RNA-based approaches could shape the future of ALS research.
This conversation also explores clinical trial failures, neuroinflammation, patient advocacy, and the human reason research matters.
