3 Introduction -Language comprehension between Alzheimer’s patients and their caregivers has to be efficient in order to have better understanding. -It is very important to research the lexical items that are more preserved in the discourse of the patients. - Few studies of language comprehension of Alzheimer’s disease patients have stressed the importance to manage adequate communication with sociolinguistic, cultural and ideological lexicon in the oral interaction. 3

4 -For this study, we used Stablex - a program for lexical textual and discursive analysis for the patients and controls productions. -Therefore, it is necessary to research the sociolinguistic, ideological cultural underpinnings to avoid more stressful situations with patients and caregivers. 4

5 Objective To verify if Alzheimer’s disease patients have preserved lexical items with historical, ideological and cultural meanings in order to create a guide of oral communication between patients and caregivers. 5

6 Methods Participants - Eight Alzheimer’s disease patients from PROTER- Old Age program – Ambulatory Care, Institute of Psychiatry, Hospital das Clinicas, School of Medicine of the University of Sao Paulo. - Patients were four male and four female aged 80 to 86 - Six healthy elderly controls aged 75 to 86, - Three male and three female, their relatives or caregivers of the patients. -All native Portuguese speakers 6

7 - Patients and controls had 4 to 11 years of education -MMSE- Mini-Mental State Exams 13 to 30. -All patients had clinical exams, neuroimages, CAMGOG- Cambridge Cognitive Test, NPI- Neuropsychiatry Inventory and several neuropsychological tests. - Besides MMSE, the controls answered to the SRQ-20 Self Reporting questionnarie. 7

Demographic and clinical data 8

9 Material - STABLEX- method of lexical, textual and discursive analysis, developed by André Camlong from the University of Toulouse, Le Mirail- France. -The method permits the construction of lexicon, tables, graphics and specific vocabularies. -It is based on mathematical-statistical-computer assisted program. - Stablex mainly distinguishes and separate the results of preferential, basic and differential vocabularies. 9

10 Procedure We talked with all the patients and controls during 15 minutes, free conversation with the themes: Education, familiy, health, food and religion. They were after transcribed and thereafter analysed by Stablex. Data analysis The results of the frecuencies of the preferential, basic and differential vocabularies of the patients and controls correlated by Chi- square. Demographic data of sex, profession and education were also analyzed and did not significat values. 10

11 Results There was a significant statistical correlation with the preferential words used by the patients. The patients expressed more preferential words because they have more lexical items preserved with historical, ideological, cultural and sociolinguistic items. 11

17 Conclusions/ Discussion -This study suggests that the word choice done by the people is not by guessing or randomized, It just does not show the character of the basic idea how the discurse is formed, but it also shows the used resources that are capable of determine the ideological, historical and cultural characteristics. - The study also showed that besides Alzheimer’s disease patients have progressive lexical lose, their preferential lexicon is still preserved and the oral communication with caregivers and relatives may be possible and rehabilitated until they reach a severe stage. 17
