A descriptive term for a brain with narrowed gyri and widened sulci which is seen in frontal and temporal lobe atrophy, which is accompanied by relative sparing of the parietal and occipital lobes, a finding characteristic of Pick’s disease, which has been fancifully likened to the appearance of a walnut. As the atrophy progresses, compensatory ventricular enlargement–ex vacuo hydrocephalus–occurs.

Alzheimer’s disease is more globally atrophied, may affect the parietal lobes, and have extreme atrophy; the changes have been called knife blade atrophy.
