SYNDROME OF FINGER AGNOSIA, DISORIENTATION FOR RIGHT AND LEFT, AGRAPHIA AND ACALCULIA: LOCAL DIAGNOSTIC VALUE

GERSTMANN, JOSEF·1940·Archives of Neurology & Psychiatry

Abstract

This paper is concerned with the syndrome, described by me some years ago, of agnosia, disorientation for right and left, agraphia and acalculia, appearing as a result of a cerebral lesion located in the transitional area of the lower parietal and the middle occipital convolution. In 1924 I first described the symptom of primary elective disability for recognizing, naming, selecting, differentiating and indicating the individual fingers of either hand, the patient's own as well as those of other persons, and called the condition finger agnosia. Subsequent to this gnostic disorientation with respect to the fingers, restriction in their separate kinetic realization not infrequently occurs. I also showed that the symptom of agnosia is characteristically associated with disorientation for right and left in respect to the patient's own body, as well as that of other persons, with special reference to the hands and fingers. The symptoms tend to appear

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
