Retrograde Memory Deficits in Severe Closed-Head Injury Patients

Disruption of temporally extended self-memory system following traumatic brain injury

“…This global impairment, irrespective of the type of representation or temporal direction, suggests that the establishment of any form of self-representation is compromised in TBI, seemingly mirroring the results reported in patients suffering from frontotemporal dementia . The finding is also consistent with previous studies revealing in severe TBI both semantic and episodic AM deficits, which covered past period (Carlesimo et al, 1998;Coste et al, 2011). The novelty here is to extend this pattern to the future period, and to highlight the weakening of temporally extended conceptual self-knowledge in TBI (decline in strength of their identity across extended time) (see 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 Table 3 Correlations between the SMS components, neuropsychological testing data and injury characteristics.…”

“…According to the literature on AM after TBI (Carlesimo et al, 1998;Coste et al, 2011;Knight and O'Hagan, 2009;Piolino et al, 2007), and the high degree of similarity between recalling the past and imagining the future (Schacter et al, 2008;Suddendorf et al, 2009;Szpunar, 2010), even in TBI (Rasmussen and Berntsen, 2014), we expected deficits in TBI patients for the evocation of both semantic and episodic self-representations regardless of the time period tested (past, recent, future).…”

“…The cerebral injuries are multiple and not homogeneous in TBI (Bigler, 2001) but they frequently concern frontal regions (Eierud et al, 2014) and may also concern hippocampal dysfunction ( Ariza et al, 2006). Several studies have demonstrated AM dysfunction after TBI (Carlesimo et al, 1998;Knight and O'Hagan, 2009) characterized by an overgeneralization of recent and remote AMs and associated with personality changes (Bach and David, 2006;Nochi, 1998;Tyerman and Humphrey, 1984). The deficit of episodic AM in TBI has been linked to the disruption of search and construction processes mediated by executive functions .…”

Selective, age‐related autobiographical memory deficits in children with severe traumatic brain injury

“…Studies published to date included adults with TBI only. These studies found deficits in autobiographical memory for personally experienced events (Carlesimo et al ., ; Knight & O'Hagan, ; Piolino, Desgranges, et al ., ), memory for personal semantic information (Levin et al ., ), and semantic and episodic components of self‐memory system (Coste et al ., ). A selective deficit in recall of episodic, but not semantic, details was found in a study by Rasmussen and Berntsen ().…”

Amnésia pós-traumática: fatores relacionados e qualidade de vida pós-trauma

“…Não obstante, alguns autores afirmam que muitas vezes essas alterações não são identificadas devido à rotina da investigação clínica e neuropsicológica ser direcionada à aquisição de novas memórias (12,13) .…”
