What If Alzheimer’s Begins With the Immune System?
Webinar Overview:
Title: Alzheimer’s Disease: Are We Missing a Key Piece of the Puzzle?
Date: May 19, 2025
Hosted by: ADPD™ Education & Mosaic of Autoimmunity
This expert-led webinar explored the complexity of Alzheimer’s disease through the lens of neurology, immunology, and autoimmunity. Topics included core pathological features (like amyloid plaques and tau tangles), motor symptoms, immune dysfunction, and a novel theory connecting polyamine metabolism and nucleolar stress to neurodegeneration.
Key Takeaways:
- Motor symptoms like slowed movement or grip weakness may show up early in Alzheimer’s and could help with earlier detection.
- Inflammation and immune system activity may play a bigger role in Alzheimer’s than previously thought.
- Researchers are exploring links between Alzheimer’s and autoimmune disease, including a new theory involving cell metabolism and stress.
- Tools like brain organoids and gene-mapping techniques are opening up new ways to study the disease and test treatments.
- Collaboration across neurology, immunology, and related fields is essential to uncover what’s really driving Alzheimer’s.
Alzheimer’s disease is usually seen as a brain disorder that causes memory loss, but what if the immune system plays a much bigger role than we thought?

This expert-led webinar explored the complexity of Alzheimer’s disease through the lens of neurology, immunology, and autoimmunity. Topics included core pathological features (like amyloid plaques and tau tangles), motor symptoms, immune dysfunction, and a novel theory connecting polyamine metabolism and nucleolar stress to neurodegeneration.
Scientists are now looking at Alzheimer’s from new angles. In addition to classic signs of disease like sticky amyloid plaques and twisted tau tangles, researchers are studying how chronic inflammation and immune dysfunction might contribute to neurodegeneration.
They’re also uncovering that Alzheimer’s may not be purely cognitive. People with the disease often show subtle motor symptoms, like slower walking, weaker grip, or finger tapping difficulties. These can appear early and may even correlate with brain biomarkers, pointing to new ways of detecting the disease before memory loss sets in.
One of the most intriguing parts of the webinar was a new theory presented by Dr. Wesley Brooks. He proposed that polyamines—molecules that help cells manage RNA and build proteins—can become dysregulated and damage the nucleolus (a key part of the cell’s control center). This disruption may trigger immune system overactivity and neurodegeneration. He connected this to both Alzheimer’s and autoimmune diseases like lupus, suggesting that stress from things like trauma or viral infections might start the whole process.
Other topics included emerging diagnostic tools, ethical questions about diagnosing Alzheimer’s before symptoms arise, and the need for interdisciplinary collaboration. Experts emphasized using brain organoids (lab-grown mini-brains) and spatial transcriptomics (which map where genes are active in brain tissue) to test new therapies and deepen understanding.
