Figure 2

Ratios of bilateral hippocampus volume measured by MRI. For (a)–(c) MRI images of DON treatment group (a), CH treatment group (b), and control group (c). The right side of the brain was on the right side of the image. For (d)–(f): decrease of the volume of bilateral hippocampus (HIP) was remarkable in control group between the mean of data measured at 48 weeks and at 0 weeks (). There were no visible volume changes of hippocampus in drug treatment groups (). Volume was accounted as a percentage of the total brain volume for each patient.
