In a study of the discourse of 100 people with Alzheimer’s disease treated for 12 months with donepezil, we observed that, as a group, they used a form of tag, described here as a self-referential tag (SRT), 14 times more frequently than did caregivers. Patients use SRTs to check propositions dependent on episodic memory as in I haven’t seen the doctor recently, have I? and to monitor information Xow as in I told you that already, didn’t I? Based on criteria developed for distinguishing checking from monitoring tags, we document the type and frequency of patients’ SRT use in the ACADIE corpus and analyze these in relation to standard measures of cognitive function (Mini Mental State Exam and Alzheimer’s Disease Assessment Scale—cognitive sub-scale) at baseline and 12 months. Patients using monitoring SRTs (ND31), with or without checking SRTs, show signiWcantly better cognitive test scores at 12 months, than are seen in patients who never use tags (ND29), or who only use checking tags (ND40). SRT use may be an independent measure of potential treatment responsiveness.
