 I personally reviewed the MRI scan of the brain from December 11, 2007 at Advanced Radiology.  It shows the ventricles are enlarged with a frontal horn span of 5.0 cm.  The 3rd ventricle contour is flat.  The span is enlarged at 12 mm.  The sylvian aqueduct is patent.  There is a pulsation artifact.  The corpus callosum is effaced.  There are extensive T2 signal abnormalities that are confluent in the corona radiata.  There are also scattered T2 abnormalities in the basal ganglia.  There is a suggestion of hippocampal atrophy.  There is also a suggestion of vermian atrophy.
