CT scan of the head at age 72 years shows (A) prominent cal-carine and Sylvian fissures and marked atrophy of the medial aspects of the occipital lobes and insular regions. B. Horizontal slice of the brain shows cortical and white matter atrophy of the medial occipital lobes. C. The cerebellar cortex is severely atrophic. D.
