Discrimination between senile dementia Alzheimer type (SDAT) patients (N = 30) and Normal Controls (N = 60) by means of a 6-test set was assessed. Performances on Word Fluency (FL), Memory for Prose (PM) and Finger Agnosia (FA) nearly exhaust the discriminant power of the whole battery, including Constructional Apraxia (CA), Token Test (TT) and Weigl's Sorting Test (WT). The battery, however, leaves some facets of the difference between SDAT patients and Controls unexplored, misclassifying almost 20% of the SDAT patients and 10% of the Controls. We emphasize the role of discriminant analysis in the evaluation of any neuropsychological battery of tests which has to be used for diagnostic purposes.

The following case report presents a patient exhibiting Gerstmann syndrome accompanied by toe agnosia. A 72 year old right handed woman had a focal lesion in the angular gyrus of the left hemisphere which was caused by a glioblastoma multiforme. The first symptom she had complained of was severe headache. Standardised neuropsychological tests of intelligence, memory, attention, fluency, apraxia, and language functions as well as tests for the assessment of agraphia, acalculia, right-left disorientation, and digit agnosia were performed. The patient displayed all four symptoms of the Gerstmann syndrome--namely, agraphia, acalculia, right-left disorientation, and finger agnosia. The patient did not display aphasia, constructional apraxia, or any other neuropsychological impairment. In addition to the four symptoms of the Gerstmann syndrome an agnosia of the toes was found. Further studies should determine whether finger agnosia in Gerstmann syndrome is usually accompanied by toe agnosia. Finger agnosia in the context of this syndrome may be better named digit agnosia.
