Brain regions with impaired blood flow have higher tau levels

In Alzheimer’s disease, impaired blood flow to brain regions coincides with tau protein buildup. This relationship strengthens as cognition declines, according to new research published in JNeurosci. Vascular function declines and amyloid-β and tau protein accumulate as Alzheimer’s disease progresses, resulting in neuron death. Like the proverbial chicken and egg, […]
