A 65-year-old retired airline pilot, who had a past history of chronic ischemic heart disease, died suddenly of a myocardial infarction. Mental function prior to his demise was normal. At autopsy the brain had a reduced weight. Sections through the cerebral cortex revealed deeply eosinophilic neurons, some of which contained remnants of pyknotic-appearing nuclear material. There was no inflammatory infiltrate or evidence of acute injury. What is the most likely cause of the changes in the brain?



A. Alzheimer disease
B. Pick's disease
C. Parkinson disease
D. Diminished blood supply
E. Spongiform encephalopathy
F. Aids dementia

Diminished blood supply is correct

Sections through the cerebral cortex showed deeply eosinophilic neurons, some of which contained nuclear remnants. These are apoptotic neurons or "red neurons" and are most often due to chronic ischemia of the brain, which is most often caused by atherosclerosis of the internal carotid arteries and/or middle cerebral arteries
