Fig. 2. Correlation between Aβ42 and Aβ40 levels in iNPH, AD, and CN subjects. The scatter plot shows the correlation between Aβ42 and Aβ40 levels. Representative images from an amyloid PET(+) AD scan and an amyloid PET(−) iNPH scan are shown on the right. Aβ: β-amyloid, AD: Alzheimer's disease, amyloid PET(+): amyloid positron-emission tomography-positive, amyloid PET(−): amyloid positron-emission tomography-negative, CN: cognitively normal, iNPH: idiopathic normal-pressure hydrocephalus.
