Allocentric Spatial Memory in Major Depressive Disorder
Major depressive disorder (MDD) is associated with small hippocampal volume (Campbell et al, 2004). This structural change does not appear to be limited to later stages of the illness, but has been found in patients suffering their first episode (Frodl et al, 2002) and in healthy individuals at risk of depression (Chen et al, 2010). This suggests that small hippocampal volume may represent a vu...
متن کاملImpaired allocentric spatial processing in posttraumatic stress disorder
A neurobiological dual representation model of PTSD proposes that reduced hippocampus-dependent contextual processing contributes to intrusive imagery due to a loss of control over hippocampus-independent sensory and affective representations. We investigated whether PTSD sufferers show impaired allocentric spatial processing indicative of reduced hippocampal functioning. Trauma-exposed individ...
متن کاملThe role of memory in posttraumatic stress disorder: A review of memory impairments and memory-based theories
Post-traumatic stress disorder (PTSD) is a psychiatric syndrome caused by exposure to threatening events such as war, car accidents, and physical and sexual assault. The experience of psychological trauma can have long-term cognitive effects. The symptoms of PTSD include changes in cognitive processes such as memory, attention, planning, and problem-solving and destructive effects on a person's...
متن کاملMemory mechanisms in posttraumatic stress disorder.
The authors present a new theory of the neurobiological mechanisms mediating the memory processes involved in posttraumatic stress disorder (PTSD). The current fear-conditioning model accounts for learning that underlies certain central features of PTSD, but it fails to account for peritraumatic memory disturbances, episodic memory phenomena that also are characteristic of the disorder. A more ...
متن کاملSubjective Premorbid Memory in Posttraumatic Stress Disorder
Background: It is unclear whether memory deficits found in patients with PTSD (posttraumatic stress disorder) precede the traumatic event and may thus represent a vulnerability factor or a consequence of the trauma. Objective: The aim of this study was to shed light on this question. Method: A newly developed neurocognitive interview to estimate premorbid memory performance was administered alo...
