RINALDI, Juciclara; SBARDELLOTO, Gabriela; KRISTENSEN, Christian Haag  and  PARENTE, Maria Alice de Mattos Pimenta. Textual reading comprehension and naming in Alzheimer's disease patients. Dement. neuropsychol. [online]. 2008, vol.2, n.2, pp.131-138. ISSN 1980-5764.

Among linguistic-cognitive failures, the retelling of stories and lexical disorders occur from the onset of AD. Recent studies have discussed whether lexical failures in AD patients include naming actions.


The aims of this study were to verify naming and reformulation of action difficulties in AD patients and their relationship with the retelling of stories. Our main questions were: Are there two linguistic abilities impaired in the early stages of AD? Is there some correlation between the capacity of naming actions and the retelling of stories?


We assessed 28 elderly participants: 17 with probable AD and 11 control subjects, with schooling ³4 years. The textual reading comprehension was measured using four stories with descriptive and narrative textual structure. The lexical production was verified by 17 actions on video, assessed by the participants' first and second verbal emissions.


The results showed that the retelling of stories is a task that discriminates patients with AD from healthy individuals. The naming and reformulation of actions tasks did not show significant differences among the patients and their controls. A positive correlation was found between the difficulties in retelling stories and the reformulation of the naming of actions.


These results confirm previous findings that show the preservation of naming actions in patients with AD, which involve familiar actions, and that the retelling of short stories is an instrument that discriminates patients with AD from healthy elders. Results also suggest that the difficulties in retelling are related a breakdown in reformulating information, perhaps stemming from mechanisms of decreased memory work.
