Liepman also reports another way that apraxia may relate to a language-related problem. Apraxia for movements of the left hand and arm may result from "disconnection" of the right motor cortex from the left hemisphere language processing system (e.g. due to a lesion affecting the corpus callosum).In this case comprehension would be intact but there is no means for that comprehension to trigger movements of the left side of the body (he had such a case). Geschwind proposed bilateral apraxia could result from disconnection of the association fibers linking the vicinity of Wernicke's area to both motor cortices. Again it is possible that comprehension could be intact (depending on the integrity of the posterior language area). Kind of like your computer "understanding" a print command but the printer not receiving the command due to a faulty cable.
