JERONIMO, Gislaine Machado  and  HUBNER, Lilian Cristine. Discourse production and communication in Alzheimer's disease: a systematic review. Neuropsicologia Latinoamericana [online]. 2014, vol.6, n.3, pp.4-15. ISSN 2075-9479.

The most frequent complaint in relation to Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD) are memory deficits. However, we know that cognition as a whole is affected in AD. And the more the disease progresses, more prominent cognitive impairment seems to be present. Since it is a disease whose cure is still unknown, scholars from different fields - by means of an interdisciplinary approach - are engaged to work in its early diagnoses and prevention. Recently, language studies have started to be conducted in AD, aiming at searching for linguistics evidence indicating the onset and the progression of the disease. The present article aims at analyzing how language is impaired in AD, especially regarding discourse production. To this end, we conducted a systematic literature review, in the databases SciELO, LILACS, SCOPUS, and PubMed, between the years 1995 and 2013, including national Brazilian and international research data. We found that the number of studies in the area is still reduced, being international studies more common than national ones. In terms of main common findings, the characteristic verified in the majority of the studies is the reduced informative character of discourse.

Keywords : Language; Discourse production; Alzheimer's disease; Differential diagnostics.
