Table 1.

Total Aβ load is significantly reduced following 5 months of anti-Aβ antibody treatment. Percent area occupied by positive immunohistochemical stain for Aβ is shown ± standard error of the mean for both the frontal cortex and hippocampus. Also shown is the percent reduction of Aβ observed following anti-Aβ antibody treatment

Region	% area positive for Aβ: control treated	% area positive for Aβ: anti-Aβ treated	% reduction following anti-Aβ antibody treatment
Frontal Cortex	34.855 ± 2.265	9.681 ± 0.754	72
Hippocampus	23.994 ± 0.985	8.212 ± 0.596	66
