AbstractObjectiveTheory of mind and destination memory are social abilities that require processing the attributes of interlocutors. Empirical research has demonstrated a relationship between performance on both abilities in normal aging and Alzheimer’s disease (AD). We therefore investigated whether processing attributes of interlocutors would result in better destination memory in AD.MethodsTwenty-six mild AD participants and 28 controls were tested on two occasions. On the first one, participants had to tell proverbs to celebrities’ faces. Following that, they decided whether they previously told that proverb to that celebrity or not. The same procedures were repeated on the second occasion; however, after telling the proverbs, participants had to introspect about what the celebrities might think about the proverbs (e.g., “what do you think that the celebrities would think about the proverbs?”).ResultsGroup comparisons showed a beneficial effect of introspection on destination memory in controls (Z = −2.57, p < .05) but not in AD participants (Z = −1.05, p = .29). However, analyzes of individual profiles demonstrated that 15 AD participants demonstrated better destination memory after introspection.ConclusionsOur findings show a beneficial effect of introspection on destination memory in normal aging, and at least in some mild AD cases. Future research should investigate the influence of social cognition on memory in AD and how introspection may provide a potential treatment for AD.

Scientific Advances

Public debate on dementia has intensified recently with scientific advances being scrutinised in the media, the genetics of Alzheimer's disease regularly portrayed as inextricably linked with the personal agony of whether to have ‘the test’ (which exists only for a small number of people) and the announcement by ex US President Ronald Reagan that he suffers from the disease. Several different areas provoke interest and speculation and this brief article attempts to highlight some, based on a recent meeting on the subject.

Destination memory is the ability to remember the receiver of transmitted information. By means of a destination memory directed forgetting task, we investigated whether participants with Alzheimer’s Disease (AD) were able to suppress irrelevant information in destination memory. Twenty-six AD participants and 30 healthy elderly subjects were asked to tell 10 different proverbs to 10 different celebrities (List 1). Afterwards, half of the participants were instructed to forget the destinations (i.e., the celebrities) whereas the other half were asked to keep them in mind. After telling 10 other proverbs to 10 other celebrities (List 2), participants were asked to read numbers aloud. Subsequently, all the participants were asked to remember the destinations of List 1 and List 2, regardless of the forget or remember instructions. The results show similar destination memory in AD participants who were asked to forget the destinations of List 1 and those who were asked to retain them. These findings are attributed to inhibitory deficits, by which AD participants have difficulties to suppress irrelevant information in destination memory.

Cognitive Control

Abstract Cognitive control constrains retrieval processing and so restricts what comes to mind as input to the attribution system. We review evidence that older adults, patients with Alzheimer's disease, and people with traumatic brain injury exert less cognitive control during retrieval, and so are susceptible to memory misattributions in the form of dramatic levels of false remembering.

Information on the conformation of paired helical filaments (PHF) and the neurofilamentous (NF) network is essential for an understanding of the mechanisms involved in the formation of the primary lesions of Alzheimer's disease (AD): tangles and plaques. The structural and chemical relationships between the NF and the PHF have to be clarified in order to discover the etiological factors of this disease. We are investigating by stereo electron microscopic and biochemical techniques frontal lobe biopsies from patients with AD and squid giant axon preparations. The helical nature of the lesion in AD is related to pathological alterations of basic properties of the nervous system due to the helical symmetry that exists at all hierarchic structural levels in the normal brain. Because of this helical symmetry of NF protein assemblies and PHF, the employment of structure reconstruction techniques to determine the conformation, particularly the handedness of these structures, is most promising. Figs. 1-3 are frontal lobe biopsies.
