New research suggests Alzheimer's may stem from an immune system disorder, not the brain itself

Alzheimer's may not be a brain disease but an immune system disorder, according to new research. This theory suggests beta-amyloid, previously thought to cause Alzheimer's, is part of the brain's immune response that mistakenly attacks healthy brain cells. This perspective challenges the long-held focus on beta-amyloid and opens avenues for new treatment approaches targeting immune pathways.
