Reminiscence group activities and discourse interaction in Alzheimer's disease.

Reminiscence is an enriching and complex experience having many purposes and functions when used with patients with Alzheimer's disease (AD). Discourse is a component of language that has been shown to decline in patients with AD (Mentis, Briggs-Whittaker, & Gramigna, 1995). This article represents one of the first studies to examine the effects of reminiscence group (RG) activities on discourse interactions in patients with AD. This article specifically addresses the AD population within a RG setting. Observations suggested that objective ratings of conversational discourse would be better (less impaired) in patients with AD when obtained in relatively unstructured environments (e.g., during RG activity) as compared to ratings obtained in conversational environments imposing more structure (e.g., a session in which language function was being evaluated). Comparisons made of conversational and narrative discourse skills observed during different testing environments in patients with AD revealed predicted outcomes. That is, discourse elicited in an environment that was less structured yielded qualitatively better discourse patterns, particularly related to selecting and maintaining a topic, requesting additional information about a topic, changing a topic during conversation, and turn-taking. Results are discussed in terms of their relevance to gerontological nurses managing patients with AD.
