Gerstmann syndrome, also known as angular gyrus syndrome, is a dominant hemisphere stroke syndrome affecting the left parietal lobe in the region of the angular gyrus, consisting of four components:
- agraphia or dysgraphia
- acalculia or dyscalculia
- finger agnosia
- left-right disorientation
Pure Gerstmann syndrome is said to be without aphasia.
History and etymology
It is named after the Austrian-American neuropsychiatrist Josef Gerstmann (1887-1969) 2, also of the Gerstmann-Sträussler-Scheinker syndrome fame.
