One of the aspects affected by AD is the language. The nature and manifestations of the difficulties on it. Are closely related with the way in which AD patients perceive and understand the world that surrounds them. This research analyzed the perception of images and a scene in motion as static and dynamic events, observing the relationship perception-language, in a sample of seven patients with AD and their respective controls. In the same way we explored a sample of language produced by patients telling the dynamic event. The results indicated significant differences in visual search, in which for the group with AD the speed decreased. In scan tasks is evidence that people with AD identified fewer elements in an image made less fixations with ineffective exploration strategies. On the Boston tests image "Theft Cookie", visual fixation parameters were similar to the control group. As for the dynamic event, the visual tracking was similar between the two groups but the linguistic expression of what is observed is affected in the group with AD revealing the relationship between perception and language as though watching the events within a moving scene, these are not subsequently recovered to be expressed linguistically. These results have important implications in identifying the nature of language difficulties in AD and in the fonoaudiological evaluation and subsequent treatment
