“…These sites form part of a broader cognitive control network, which supports sustained attention and goal-directed cognition, as well as a range of cognitively demanding tasks such as planning and problem-solving [67]. Recent studies indicate that disruption of this frontoparietal cognitive control network in AD adversely impacts episodic memory performance [68]. Our finding of bilateral angular gyri involvement irrespective of PM subtype in AD is therefore notable.…”

“…Such an analysis may partially emphasize some regions and ignore others. Two studies were ruled out, because their stereotactic results were not reported (Dhanjal et al, 2013; Dhanjal and Wise, 2014). Another two studies were excluded because they did not reveal any differences in activation between individual with aMCI and normal controls (Parra et al, 2013; Nicholas et al, 2014).…”

The present study conducted a quantitative meta-analysis aiming at assessing consensus across the functional neuroimaging studies of episodic memory in individuals with amnestic mild cognitive impairment (aMCI) and elucidating consistent activation patterns. An activation likelihood estimation (ALE) was conducted on the functional neuroimaging studies of episodic encoding and retrieval in aMCI individuals published up to March 31, 2015. Analyses covered 24 studies, which yielded 770 distinct foci. Compared to healthy controls, aMCI individuals showed statistically significant consistent activation differences in a widespread episodic memory network, not only in the bilateral medial temporal lobe and prefrontal cortex, but also in the angular gyrus, precunes, posterior cingulate cortex, and even certain more basic structures. The present ALE meta-analysis revealed that the abnormal patterns of widespread episodic memory network indicated that individuals with aMCI may not be completely “mild” in nature.

“…These higher order executive functions are based on more fundamental frontal lobe functions, such as attention. Attention, is required for conscious recollection of autobiographic episodic memories (Dhanjal and Wise, 2014) and is diminished in AD (Kim et al, 2011). Therefore, attentional deficits in AD may contribute to autobiographical memory dysfunction.…”

Autobiographical memory, or memory for personal experiences, allows individuals to define themselves and construct a meaningful life story. Decline of this ability, as observed in Alzheimer’s disease (AD), results in an impaired sense of self and identity. In our model (AMAD: Autobiographical Memory in Alzheimer’s Disease), we present a critical review of theories and findings regarding cognitive and neuroanatomical underpinnings of autobiographical memory and its decline in AD and highlight studies on its clinical rehabilitation. We propose that autobiographical recall in AD is mainly characterized by loss of associated episodic information, which leads to de-contextualization of autobiographical memories and a shift from reliving past events to a general sense of familiarity. This decline refers to retrograde, but also anterograde amnesia that affects newly acquired memories besides remote ones. One consequence of autobiographical memory decline in AD is decreased access to memories that shape self-consciousness, self-knowledge, and self-images, leading to a diminished sense of self and identity. The link between autobiographical decline and compromised sense of self in AD can also manifest itself as low correspondence and coherence between past memories and current goals and beliefs. By linking cognitive, neuroanatomical, and clinical aspects of autobiographical decline in AD, our review provides a theoretical foundation, which may lead to better rehabilitation strategies.
