Emotion and recollective experience in Alzheimer’s disease
(English)Manuscript (preprint) (Other academic)
Emotional changes are common in Alzheimer’s disease (AD). In addition, damage to brain regions involved in emotion is abundant in AD. Although these finding imply that emotion memory is severely compromised in AD, absolute or relative sparing of emotional memory has occasionally been reported. Hence, we wanted to clarify how well AD patients can remember emotion words. Eighteen AD patients and fifteen healthy older persons participated in the experiment. Participants studied neutral, positive, and negative words. Implicit and explicit memory was assessed in two tasks: a word-fragment completion task and a recognition task, respectively. In the latter task, participants were asked to provide recollective judgments when they indicated that they recognized a word from previous study. Results indicated that AD patients responded to valence, and in particular negative valence, similar to controls, that AD patients evidenced severe deficits as to recollective experience, and that implicit memory remained intact in AD.
