“…However, it is not always the case that the generation of fewer internal details is accompanied by a greater number of external details. For example, individuals diagnosed with bipolar disorder and even cases of MTL amnesia have been found to produce prospective narratives that are significantly impoverished in terms of number of internal details, yet the number of external details produced was found to be similar to that of controls (King et al, 2011;Race et al, 2011, respectively). A paucity of internal details and an increase in number of external details may reflect two distinct clinical features.…”

Previous reports of episodic prospection impairment in medial temporal lobe (MTL) amnesia might misrepresent an individual case's true prospective abilities Specific cues drawn from a patient's everyday life have greater ecological validity than the more typical generic cues used to elicit episodic prospection and can aid some individuals with MTL amnesia in the ability to imagine future experiences Assessment and rehabilitation tools for MTL amnesic populations should attempt to minimize broad, open-ended questions and instead provide more structured and personally meaningful cues to guide responses Further research is needed to determine case-specific characteristics that best predict benefit from specific, personal cues. These might include extent of MTL damage and overall severity of episodic memory and prospection impairment.

“…In BD, autobiographical memory research has found both a negative and an over‐general memory bias in euthymic individuals which is associated with social problem‐solving ability . Extending this notion further, King and colleagues discovered that depressed and manic patients with BD included significantly less detail when generating future events in response to a cue word compared to controls, irrespective of the valence of the cue word, indicating the constraint placed by over‐general encoding on the ability to generate solutions for future events. This was most prominent in those who were symptomatic (mania or depression) at the time of testing, and those with a greater number of past manic episodes , suggesting once again that in BD, cognitive compromise is both trait‐ and state‐related.…”

The proposed Bipolar Suicidality Model (BSM) highlights the psychosocial precursors to suicidality in BD, while recognizing the key role of cognitive deficits and underlying functional neurobiological abnormalities. It usefully integrates our knowledge, and provides a novel perspective that is intended to meaningfully inform future research initiatives, and can lead to a better understanding of suicidality in bipolar disorder. Ultimately, it is hoped that it will facilitate the development of targeted interventions that diminish the risk of suicide in bipolar disorder.

“…For example, clinical studies have found that patients suffering episodic memory impairment also experienced difficulty imagining personal future events (Addis et al, 2009; Lind and Bowler, 2010; Matthew and Lori-Anne, 2011; de Vito et al, 2012a; Brown et al, 2013). Additionally, extensive neuroimaging research suggests that a common brain network including the medial temporal lobe, prefrontal cortex, and posterior parietal cortex underlies both episodic memory and EFT (Okuda et al, 2003; Addis et al, 2007; Schacter et al, 2007, 2008, 2012; Szpunar et al, 2007).…”

Episodic and Semantic Memory Contribute to Familiar and Novel Episodic Future Thinking

Increasing evidence indicates that episodic future thinking (EFT) relies on both episodic and semantic memory; however, event familiarity may importantly affect the extent to which episodic and semantic memory contribute to EFT. To test this possibility, two behavioral experiments were conducted. In Experiment 1, we directly compared the proportion of episodic and semantic memory used in an EFT task. The results indicated that more episodic memory was used when imagining familiar future events compared with novel future events. Conversely, significantly more semantic memory was used when imagining novel events compared with familiar events. Experiment 2 aimed to verify the results of Experiment 1. In Experiment 2, we found that familiarity moderated the effect of priming the episodic memory system on EFT; particularly, it increased the time required to construct a standard familiar episodic future event, but did not significantly affect novel episodic event reaction time. Collectively, these findings support the hypothesis that event familiarity importantly moderates episodic and semantic memory's contribution to EFT.
