Fluorescent compounds allow clinicians to visualize Alzheimer's disease as it progresses

What if doctors could visualize all of the processes that take place in the brain during the development and progression of Alzheimer's disease? Such a window would provide a powerful aid for diagnosing the condition. Now, researchers have developed a new class of imaging agents that enables them to visualize tau protein aggregates, a pathological hallmark of Alzheimer's disease and related neurodegenerative disorders, directly in the brains of living patients.
