  • Abstract
  • Look Inside

We discussed the difference in symptomatologies and the site of a responsible lesion between diagonis-tic dyspraxia and callosal apraxia.

From our experience and a review of the literature, diagonistic dyspraxia could be better defined as the abnormal motor behavior of the left hand triggered by voluntary movements of the right hand or even by mere intention of the movements. Callosal apraxia, on the other hand, is characterized by amovement disorder such as amorphous or parapraxic movements or perseveration confined to the left hand and induced by verbal commands.
