Back 1

Henschen

Front 2

Which is more common, primary acalculia or secondary acalculia?

Back 2

secondary

Front 3

Hecaen proposed a classification system for acalculias based on presumed mechanism of disorder. What are his 3 classes of acalculia?

Back 3

acalculia associated with alexia and agraphia for numbers, acalculia of the spatial type, anarithmetria

Front 4

In ability to read or write numbers strongly suggests ___(right/left___ parietal lesion, but does not rule out involvement of the __(right/left)___ hemisphere.

Back 4

left, right

Front 5

Alexia for arithmetical signs with preserved reading of numbers is often associated with focal lesions in which hemisphere? in which lobes?

Back 5

left; parietal or temporo-occipital

Front 6

The spatial type of acalculia suggests post-rolandic lesion of which hemisphere?

Back 6

right

Front 7

Gerstmann's syndrome is associated with what 4 features?

Back 7

agraphia, right-left disorientation, finger agnosia, acalculia

Front 8

Gerstmann's syndrome is associated with which type of alcalculia - anarithmetria, spatial type, both, neither

Back 8

both anarithmetria and spatial type alcalculia

Front 9

Alcalculia of the spatial type generally is associated with ___(visual-constructive/auditory-verbal)___ impairments.

Back 9

visual-constructive. The right hemisphere is implicated and is rare with left hemisphere lesions.

Front 10

Back 10

Lexical, syntactic

Front 11

Acalculia associated with alexia and agraphia, acalculia of the spatial type, and anarithmetria are most commonly associated with deficits in which hemisphere, respectively?

Back 11

left hemisphere; right hemisphere; left hemisphere and bilateral involvement
