The natural course of acalculia in left-brain-damaged patients

Acalculia is a frequent disorder in left-brain-damaged patients but nothing is known about its natural course. We report a study on 51 vascular acalculic patients examined at least twice. Our results indicate that recovery from acalculia is possible in the first months post-stroke, that initial severity does not significantly influence recovery, and that it correlates with recovery of auditory comprehension.
