Doctors Reveal the EARLY Signs of Alzheimer’s (Before Memory Loss) With Dr. Melissa Murray
What if Alzheimer’s isn’t just one disease but a family of diseases? In this episode, I’m thrilled to be joined by Dr. Melissa Murray, a professor of neuroscience at the Mayo Clinic. Dr. Murray’s groundbreaking research focuses on Alzheimer’s, dementia with Lewy bodies, and other neurodegenerative conditions. She leads the Mayo Clinic’s Translational Neuropathology Lab, where her team combines neuropathology, neuroimaging, and genetics to understand these diseases better.
Dr. Murray is one of the recent winners of the Rainwater Prize for Outstanding Innovation in Neurodegenerative Research, which came with a $400,000 prize to further her and her colleague Dr. Dennis Dickson’s research at Mayo Clinic.
The Rainwater Prize honors scientific contributions to the field of neurodegenerative research that focus on diseases associated with the accumulation of tau protein in the brain, with the goal of translating discoveries into meaningful therapeutic and diagnostic innovations.
Today’s discussion tackles a critical issue in brain health: treating Alzheimer’s like it’s a single disease. With advances in neuroimaging and biomarkers, we can now diagnose Alzheimer’s while people are still alive, which is a huge step forward from the past. Dr. Murray also highlights how brain donation is helping researchers like her gain deeper insights into the causes and progression of Alzheimer’s.
“We can't help our genetics. We're blessed with what we were given, but we also get to play that deck of cards that we're handed, and we have a chance to make a difference.”

Doctors Reveal the Early Signs of Alzheimer’s (Before Memory Loss) With Dr. Melissa Murray
Are you noticing subtle changes in your loved one’s behavior or cognitive function, but you’re not sure if it’s Alzheimer’s? Alzheimer’s disease isn’t just about memory loss—it’s a complex condition with early signs that often go unnoticed. In this episode of Alzheimer’s Breakthrough, Dr. Josh Helman sits down with Dr. Melissa Murray, a neuroscience professor at the Mayo Clinic, to discuss the early signs of Alzheimer’s and how we can better understand and detect this disease before it’s too late.
In this enlightening conversation, Dr. Murray provides insight into the latest advancements in Alzheimer’s research, the biomarkers that could detect the disease early, and the surprising ways Alzheimer’s can show up long before memory loss. Keep reading to learn how these early signs can make all the difference in managing and preventing Alzheimer’s.
🎯 Key Takeaways From the Episode:
- Early signs of Alzheimer’s go beyond memory loss and include behavioral changes, vision problems, and difficulty with planning and coordination.
- Vascular health plays a significant role in Alzheimer’s, with some early-onset Alzheimer’s cases showing little vascular contribution.
- Biomarkers and imaging technology are now being used to track Alzheimer’s changes before symptoms arise, giving us a better window into early detection.
- Lifestyle changes like exercise and brain-boosting activities can reduce Alzheimer’s risk, even if you have a genetic predisposition.
The Early Signs of Alzheimer’s
When we think of Alzheimer’s, memory loss is often the first thing that comes to mind. However, Dr. Murray emphasizes that Alzheimer’s disease presents itself in multiple ways before memory loss becomes apparent. Changes in behavior, difficulty with coordination, and vision problems are among the early signs of Alzheimer’s. These symptoms are often mistaken for normal aging or other conditions, but they’re crucial clues that shouldn’t be overlooked.
Dr. Murray discusses how early-onset Alzheimer’s can manifest as early as the 30s or 40s, particularly in cases where vascular health isn’t as involved. This highlights the importance of recognizing Alzheimer’s at an earlier stage, as earlier detection could lead to more effective interventions.
The Role of Vascular Health
Vascular health has increasingly been recognized as a significant contributor to Alzheimer’s. Dr. Murray notes that vascular changes—such as issues with blood flow in the brain—are often present in Alzheimer’s patients, especially those with later stages of the disease. However, early onset Alzheimer’s patients often show fewer signs of vascular damage.
Understanding this connection has led to improvements in dementia treatment and prevention, as we now know that addressing vascular health can help prevent cognitive decline. This is particularly important because vascular contributions can often be addressed through lifestyle changes, like diet and exercise.
Biomarkers and Imaging
Dr. Murray reveals the exciting advancements in neuroimaging and blood biomarkers. These technologies allow researchers and doctors to track Alzheimer’s disease progression in real-time, even before symptoms appear. This gives doctors a much better ability to diagnose the disease earlier, which is key for providing patients with the best possible care.
Imaging tools like MRI and PET scans have made great strides in detecting changes in the brain, such as amyloid plaques and tau tangles, which are hallmarks of Alzheimer’s. The ability to visualize these changes is game-changing because it allows doctors to predict and monitor the disease before patients even begin to experience memory loss.
Lifestyle Changes to Lower Alzheimer’s Risk
While there’s no cure for Alzheimer’s yet, lifestyle changes can significantly reduce the risk. Dr. Murray emphasizes the importance of activities that stimulate the brain, such as exercise, mental exercises, and maintaining social connections. These activities can slow the progression of Alzheimer’s and even reverse some of the cognitive declines associated with aging.
The evidence is clear: Alzheimer’s risk can be mitigated with early intervention and healthy habits. For those at genetic risk, like those with the ApoE4 gene, these interventions become even more critical in preventing the disease.
Conclusion:
Early detection of Alzheimer’s is critical for improving outcomes and quality of life for those affected by the disease. As Dr. Murray and Dr. Helman discussed, Alzheimer’s isn’t just about memory loss—it’s a multifaceted disease that requires a comprehensive approach to detection and care. With advancements in biomarkers, imaging, and lifestyle interventions, there’s hope for preventing and managing Alzheimer’s before it takes hold.
