Gerstmann syndrome
Pronunciation: GERST-mahn
A neuropsychological syndrome comprising four core deficits: finger agnosia, left-right disorientation, agraphia, and acalculia.
Full Definition
Gerstmann syndrome is a classic neuropsychological constellation resulting from lesions in the dominant parietal lobe, specifically the angular gyrus region. The syndrome consists of four cardinal symptoms: finger agnosia (inability to identify or name fingers), left-right disorientation, agraphia (writing difficulties), and acalculia (calculation impairment). While the existence of this syndrome as a unified entity has been debated, the tetrad remains clinically recognized and educationally important. The condition typically results from dominant hemisphere parietal strokes, tumors, or degenerative processes affecting the angular gyrus.
Usage
