As consciousness improved, each patient developed Lance-Adams type multifocal myoclonus, but the eventual outcome was satisfactory. Only one patient needed assistance to walk, and all three were self caring. One patient had persistent dyscalculia. Early myoclonic status is not necessarily an agonal event, particularly when it follows arrest due to acute asthma or asphyxia. Acalculia is an acquired disturbance of calculation that has several clinical expressions.
Disturbances cna be aphasic and nonaphasic.
Further division is into alexia and agraphia for numbers, anarithmetria and spatial acalculia. In addition to these manifestations due to focal cerebral lesions also diffuse lesions can produce disturbance of calculia. Acalculia is also encountered as a developmental disturbance. Testing of acalculia has to encroach both oral and written calculations with clinical and standardized neuropsychological tests. Alyn Hospital, Jerusalem, Israel.
