Recurrent Brain Trauma May Increase Alzheimer’s Risk

Caption

Parametric maps of amyloid deposition in healthy control participants (A and B) and blast-exposed military instructors (C and D) at baseline (A and C) and follow-up (B and D). The blue-to-red scale indicates the frequency of statistically abnormal amyloid uptake in a particular brain voxel. Whereas no abnormal amyloid uptake was identified at baseline or follow-up in healthy control participants (A, B), amyloid deposition occurred most frequently in blast-exposed participants in the superior parietal lobules, precuneus, cingulum, paracentral lobules, and anterior temporal and occipital lobes (D). A = anterior, Ant = anterior, I = inferior, Inf = inferior, L = left, Lat = lateral, Med = medial, P = posterior, Post = posterior, R = right, S = superior, Sup = superior.
