The present invention relates to an improved apparatus for self-administering audio- visual stimulation therapies comprising at least one horizontally-extending curved screen (11,11') for delivering visual stimuli spatially distributed in an angular range substantially equal to the angular portion of extension of the screen (11,11'); at least one acoustic source (12, 12') for delivering acoustic stimuli spatially distributed in an angular range at least in part coinciding with the angular range of spatial distribution of the visual stimuli, the at least one curved screen (11,11') and the at least one acoustic source (12,12') being connected to an electronic central processing unit (20) implementing at least activation means of the visual and/or acoustic stimuli; at least one signalling interface (21) able to be actuated by the patient to indicate the detection of at least one delivered stimulus connected to means for collecting data relative to the activation of the visual and/or acoustic stimuli and of the actuation of said signalling interface, characterized in that the curved screen (11,11') is suitable for providing a visual signal suitable for guiding the gaze of the patient so as to take it in a condition in which it looks centrally with respect to the curved horizontal extension of the screen (11,11').La présente invention concerne un appareil amélioré d'auto-administration de thérapies de stimulation audio-visuelle comprenant au moins un écran incurvé s'étendant horizontalement (11, 11') pour fournir des stimuli visuels distribués dans l'espace dans une plage angulaire sensiblement égale à la partie angulaire d'extension de l'écran (11, 11') ; au moins une source acoustique (12, 12') pour fournir des stimuli acoustiques distribués dans l'espace dans une plage angulaire coïncidant au moins en partie avec la plage angulaire de la distribution spatiale des stimuli visuels, le ou les écrans incurvés (11, 11') et la ou les sources acoustiques (12, 12') étant racc
