Alzheimer's disease, one of the most prevalent neurodegenerative disorders globally, affects millions of people and places a substantial burden on individuals, families, and healthcare systems. Central to the pathology of Alzheimer's are two protein abnormalities: amyloid plaques and neurofibrillary tangles composed of tau protein. These biological hallmarks serve not only as diagnostic indicators but also as key contributors to disease progression. Over the last few decades, scientists have extensively investigated how amyloid beta and tau proteins interact to form these plaques and tangles in the brain, attempting to untangle their roles in memory loss, cognitive decline, and neuronal dysfunction. While our understanding of Alzheimer's continues to evolve, much of the conversation surrounding the disease hinges on decoding what causes amyloid plaques, how tau tangles develop, and the implications of these abnormalities on brain health
