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

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.00:00 Introduction to Dr. João Pereira00:58 Dr. Pereira’s research journey05:29 Academia vs industry in science careers12:28 What is ALS?16:48 Is ALS only a motor neuron disease?19:01 Biomarkers and early diagnosis challenges20:44 Genes involved in ALS: TDP-43, SOD1, and more22:44 How organoids are made from patient-derived stem cells27:24 Organoids vs animal models in ALS research31:00 Modeling inflammation and drug screening33:54 Why ALS varies across patients and mutations35:35 Why ALS treatments often fail in clinical trials38:09 RNA therapies and C9orf7242:04 Is neuroinflammation important in ALS?45:05 AI and computational tools in neuroscience47:39 Using AI for large-scale image analysis50:29 What could accelerate ALS research?52:52 Funding, advocacy, and patient-driven research54:24 Why ALS research matters beyond the lab55:10 A rare disease story that shows the impact of research59:09 Closing thoughts
