L'image spéculaire chez les sujets souffrant d'une lésion hémisphérique droite et présentant une anosognosie

Abstract : An historical and critical reading of the theorical material and the confrontation of left hemiplegic individuals with their own mirror picture are going to be two complementary ways methodically used for understanding anosognosia. The main purpose of theorical and clinical approach is, by the use of a mirror, to provide the patient who "disregards" his affection with the opportunity to "regard" himself as a bodily struck individual. The first aim is to compare both verbal and behavioral reactions of the person towards his paralysis, before he sees himself in the mirror, with while he is seeing himself in that mirror. What do we observe at the outcome of this mirror trial? Does it make left hemiplegic individual change his opinion about his pathology (anosognosia or anosodiaphoria) and or does it make him change his attitude towards the left half of his body (hemiasomatognosia or left half motor spontaneity) ? We record that the individual in front of his mirrored picture takes it into consideration. the mirror trial brings evidences confronted with that cannot be observed (since the left half of his body doesn't respond to the orders o his brain) the person wonders about his health and starts to be aware of his state... he finally discovers a strife between what he perceives of his motioning body and what he feels inside his left arm and leg. From this appreciation of his deficiency he switches then to admission of his own pathology. Among various theories concerning anosognosia the considered etiology is whether an organically or a psychological one. However none takes into consideration that realization of left hemiplegic and its repercussions on the body varies according to the visual self perception of his motor deficiency by the hemiplegic person. This deficiency being the sole outwards consequence of the disease and that's what has been tried to be demonstrated.
