Meaningful conversation with individuals in the later stages of Alzheimer's disease (AD) has been considered difficult if not impossible. Limiting communication to simple concrete subjects and closed-ended questions is frequently recommended. Thirty-five 30 minute conversations with individuals with advanced AD (mean Mini-Mental State Examination [MMSE] = 10) were transcribed and the interactions examined. No significant differences in length or relevance of response by type of question was found indicating that subjects were able to respond to open-ended questions. Use of broad opening statements or questions, establishing commonalities, speaking as equals, and sharing of self-facilitated expression of feeling; recognizing themes with salience for the individual helped to maintain the discussion.

Evidence suggests the persistence of awareness of self into the middle and late stages of Alzheimer's disease. Failure to recognize the continuing awareness of self and the human experience of the person in the middle and late stages can lead to task-oriented care and low expectations for therapeutic interventions. The bafflement noted in respondents suggests that people should be told their diagnosis and offered an explanation of what this diagnosis means.
