Brain (top) and MRIs (transverse plane, 2-4; coronal plane, 5) from a person with Alzheimer disease (A) and a healthy person (B). The brain views show generalized atrophy in Alzheimer disease. The MRIs (2-5) show cortical atrophy and ventricular enlargement. The MRIs are T1 images; brain tissues are shades of gray and cerebrospinal fluid, black.
