The current state of science on aphasia

Abstract

We very often come across agraphy as a complication in any form of rupture disorder. This even in some forms of verbal speech is a direct consequence of it. For most people, even for many who have been, the right hand has the ability to write; it, therefore, is located under the influence of the center, which innervates the movements of the right hand. The paralysis of the right hand, in the face of a lesion in the center of the upper limb (the middle third of both central gyri), will, of course, destroy the careful movement necessary for writing. Sometimes, on the other hand, agraphia without the slightest damage to the motor function of the hand is subject to even greater doubt. Even Pitres's remarkable case showed mild motor and sensory disorders. Such disorders, perhaps, are easier to detect on the hands, than similar disorders with local aphasia on the lips, tongue, etc., since there can be corrected in the result of external infiltration from the opposite hemisphere, which is impossible here. But in any case, there is a connection on one side of the r between the normal state of the hand and the ability to write on the other side between agraphia and paralysis of the right hand.
