“…Moreover, it has been suggested that the degree of impairment of semantic ABM may depend on the stage of the disease. While episodic autobiographical memory can be affected in early AD, semantic components may be preserved, becoming impaired only in more severe stages of the condition (Seidl et al, 2011;Kirk and Berntsen, 2018). The temporal gradient is also evident from the early stages of dementia for episodic ABM, while semantic ABM seems to be characterized by a flatter distribution across lifetime periods (Seidl et al, 2011).…”

The Petrified Self 10 Years After: Current Evidence for Mnemonic anosognosia

Lack of awareness about disease, its symptoms and consequences, also termed anosognosia, is a common feature of Alzheimer's disease (AD). It has been hypothesized that memory disorder may be a key contributing factor to anosognosia, with people with AD not being able to update their personal information about performance and relying on older consolidated material about ability. This potentially outdated sense of self has been named, as a metaphor, the petrified self. In the current review, evidence from the past 10 years in relation to this concept is critically appraised. In particular, focus is given to empirical evidence produced on anterograde memory deficits about performance, the profile of autobiographical retrograde memory loss and the role of frontal lobes in anosognosia in AD. Finally, wider consequences of this metaphor for the understanding of selfhood in dementia are discussed.

“…Specifically, retrieval of remote material seems to be better preserved than recent memories. Overall, it has been highlighted that in AD ABM impairments are characterized by a temporal gradient for both episodic and semantic components (Leyhe et al, 2009;Thomann et al, 2012;De Simone et al, 2016;Kirk and Berntsen, 2018).…”

“…Barnabe et al . () and more recently Kirk and Berntsen () highlighted that the presence/absence of TG in different studies may be due to the different number of retrieved epochs and events assessed by the two tests. In particular, the AMI requires three events to be retrieved from three different periods of life (childhood, early adult life, and recent adult life; conversely, the AI requires that a single event be recalled from five periods of life (early childhood, adolescence–teenage years, early adulthood, middle age, and the previous year).…”

“…Some studies have reported a significant TG for personal episodic (but not for semantic) memories in patients with preclinical AD (a condition known as Mild Cognitive Impairment [MCI]; Greene et al ., ; Leyhe et al ., ) and fully developed AD (Greene et al ., ; Irish, Lawlor, et al ., ). Moreover, TG for semantic information in patients with AD has been documented either in isolation (Gilboa et al ., ; Irish et al ., ; Ivanoiu et al ., ) or in association with TG for personal episodic memories (Kirk & Berntsen, ; Kopelman, ; Leyhe et al ., ). Finally, autobiographical episodic memory deficits have also been documented in the absence of any gradient (Irish, Hornberger, et al ., ; Murphy et al ., ).…”

“…The Autobiographical Memory Interview (AMI; Kopelman, Wilson, & Baddeley, 1989) and the Autobiographical Interview (AI; Levine, Svoboda, Hay, Winocur, & Moscovitch, 2002) have frequently been used to assess the many aspects of the rABM (Barnabe et al, 2012). Barnabe et al (2012) and more recently Kirk and Berntsen (2018) highlighted that the presence/absence of TG in different studies may be due to the different number of retrieved epochs and events assessed by the two tests.

The role of the hippocampus and neocortical areas in the retrieval of past memories in pre‐dementia Alzheimer's disease (AD) patients was investigated. The aim was to assess whether the hippocampus has a temporary role in memory trace formation, according to the Cortical Reallocation Theory (CRT), or whether it continuously updates and enriches memories, according to the Multiple Trace Theory. According to the former theory, hippocampal damage should affect more recent memories, whereas the association cortex is expected to affect memories of the entire lifespan. In the second case, damage to either the hippocampus or the association cortices should affect memories of the entire lifespan. Seventeen patients with amnestic Mild Cognitive Impairment due to AD were submitted to autobiographical (i.e., episodic and semantic personal) memory assessment. Patients underwent MRI for the acquisition of T1‐weighted brain volumes. Voxel‐based morphometry was used to assess correlations between grey matter (GM) volumes and autobiographical memory. Correlation analyses revealed a strict association between GM volumes in the hippocampus and patients’ ability to retrieve the most recent but not the oldest autobiographical memories in both aspects, episodic and semantic. Moreover, patients’ GM volumes in the pre‐frontal and temporal polar areas were associated with recollection of episodic and semantic events, respectively. Finally, GM volumes in the precuneus and occipital cortex were associated with retrieval of the most recent episodic events. These findings indicate that the hippocampus has a specific time‐dependent role; thus, they support the CRT.

In healthy adults, autobiographical memories (AMs) evoked by music appear to have unique cognitive characteristics that set them apart from AMs evoked by other cues. If this is the case, we might expect music cues to alleviate AM deficits in clinical disorders. This systematic review examines music-evoked autobiographical memories (MEAMs) in clinical populations, focusing on cognitive characteristics, and whether MEAMs differ from AMs evoked by other stimuli.We identified 15 studies featuring participants with Alzheimer's disease (AD), behavioral variant -Frontotemporal dementia (bv-FTD), acquired brain damage, and depression. We found that music evokes AMs in these disorders, and that familiar music was more likely to evoke AMs. Compared with healthy controls, AD participants had a relative advantage for MEAMs over picture-evoked AMs. People with damage to the medial prefrontal cortex showed preserved access to MEAMs in terms of frequency, but a relative disadvantage regarding the episodic richness for MEAMs, but not for memories cued by pictures, compared to controls. Participants with bv-FTD had fewer AMs evoked after both music and pictures than healthy controls. Across conditions, MEAMs were generally specific and retrieved fast, suggesting little retrieval effort. MEAMs were also positive, except in depression, where as many negative as positive AMs were produced. These findings suggest several underlying cognitive and affective mechanisms of MEAMs, including anxiety reduction, increased fluency, musicevoked emotions, reminiscence, and involuntary retrieval, and that these might be moderated by musical abilities and memory for music. In conclusion, MEAMs appear to be relatively well preserved, especially in AD.
