[Rehabilitation of language processing disorders in bilingual patients with Alzheimer disease]

We studied the levels of language production processing of bilingual subjects with Alzheimer's disease (AD). The results focus on the deficit of levels of language production processing of bilingual patients with AD at the semantic level of the first language in two aspects, which are the procedure based on the lexical implications of the terms and the continuity. While the grammatical level seems rather affected in the second language (L2) and relatively spared in the first language (L1). Consequently, the cognitive-language stimulation protocol for bilingual patients with AD is developed to offer cognitive training adapted to this deficit. The present study aims at assessing the effectiveness of PSCLAB in the rehabilitation of disturbed levels of language production processing in bilingual patients with AD from early to medium stage, by analyzing the discourse of 30 bilingual patients before and after the administration of the protocol. The results of this study suggest a cognitive language training. The PSCLAB seems effective in the rehabilitation of disturbed levels of language production processing in these patients, although controlled studies with larger samples may be necessary in order to conclude to a therapeutic efficacy of this protocol.
