Ptsd Symptoms

Impairments in declarative memory have been reported in posttraumatic stress disorder (PTSD). Fragmentation of explicit trauma-related memory has been assumed to impede the formation of a coherent memorization of the traumatic event and the integration into autobiographic memory. Together with a strong non-declarative memory that connects trauma reminders with a fear response the impairment in declarative memory is thought to be involved in the maintenance of PTSD symptoms. Fourteen PTSD patients, 14 traumatized subjects without PTSD, and 13 non-traumatized healthy controls (HC) were tested with the California Verbal Learning Test (CVLT) to assess verbal declarative memory. PTSD symptoms were assessed with the Clinician Administered PTSD Scale and depression with the Center of Epidemiological Studies Depression Scale. Several indices of the CVLT pointed to an impairment in declarative memory performance in PTSD, but not in traumatized persons without PTSD or HC. No group differences were observed if recall of memory after a time delay was set in relation to initial learning performance. In the PTSD group verbal memory performance correlated significantly with hyperarousal symptoms, after concentration difficulties were accounted for. The present study confirmed previous reports of declarative verbal memory deficits in PTSD. Extending previous results, we propose that learning rather than memory consolidation is impaired in PTSD patients. Furthermore, arousal symptoms may interfere with successful memory formation in PTSD.

Neural Signature

A recent study used functional neuroimaging and cognitive tasks to identify posttraumatic stress disorder (PTSD) subtypes. Specifically, this study found that a subgroup of patients with verbal memory impairment had a unique neural signature, namely, decreased ventral attention network (VAN) resting-state functional connectivity, and these same individuals responded poorly to psychotherapy. Although this represents one of the first studies to propose a neurocognitive subtype of PTSD and has far-reaching translational potential, the generalizability and specificity of the observed neural network and cognitive domain remain unclear. We attempted to conceptually replicate and extend these findings in a similar cohort of combat-exposed veterans (n = 229) tested using a standardized battery of neuropsychological tests and a priori criteria for cognitive impairments. First, we conducted identical and complementary analyses to determine whether subjects with PTSD and neuropsychologically defined verbal memory deficits exhibited the VAN connectivity biomarker. Second, we examined whether cognitive deficits in other domains implicated in PTSD (executive functioning and attention) exhibited the VAN signature. Across multiple measures of verbal memory, we did not find that the subgroup of individuals with PTSD and memory impairments had lower VAN connectivity. However, a subgroup of individuals with PTSD and attentional impairments did have lower VAN connectivity, suggesting that the original subtype could have been related to attention and not memory impairments. Overall, our findings suggest that the previously identified memory-impaired PTSD subtype may not generalize. Further consideration of neuropsychological methods will be important for neurocognitive markers to be implemented clinically.

Magnitude Improvement

AbstractIntravenous (IV) subanesthetic doses of ketamine have been shown to reduce psychiatric distress in both major depressive (MDD) and posttraumatic stress disorder (PTSD). However, the effect of ketamine on cognitive function in these disorders is not well understood. To address this gap, we examined the effect of a single dose of IV ketamine on cognition in individuals with MDD and/or PTSD relative to healthy controls (HC). Psychiatric (n = 29; 15 PTSD, 14 MDD) and sex- age- and IQ matched HC (n = 29) groups were recruited from the community. A single subanesthetic dose of IV ketamine was administered. Mood and cognitive measures were collected prior to, 2 h and 1 day post-ketamine administration. MDD/PTSD individuals evidenced a large-magnitude improvement in severity of depressive symptoms at both 2-hours and 1 day post-ketamine administration (p’s < .001, Cohen d’s = 0.80–1.02). Controlling for baseline performance and years of education, IV ketamine induced declines in attention (ATTN), executive function (EF), and verbal memory (VM) 2 h post-administration, all of which had resolved by 1 day post-ketamine across groups. The magnitude of cognitive decline was significantly larger in MDD/PTSD relative to HC on attention only (p = .012, d = 0.56). Ketamine did not affect working memory (WM) performance. Cognitive function (baseline, change from baseline to post-ketamine) was not associated with antidepressant response to ketamine. Results suggest that while ketamine may have an acute deleterious effect on some cognitive domains in both MDD/PTSD and HC individuals, most notably attention, this reduction is transient and there is no evidence of ketamine-related cognitive dysfunction at 1 day post-administration.

The aim of this study was to examine the effect of posttraumatic stress disorder (PTSD) on (a) neuropsychological test performance and (b) self-reported emotional complaints within individuals suffering from postconcussional disorder (PCD) after a mild traumatic brain injury (MTBI). A two-group comparative research design was employed. Two MTBI samples with and without PTSD were assessed with a neuropsychological test battery and the Ruff Neurobehavioral Inventory (RNBI). On the neurocognitive test performances no significant between group differences were found, but the MTBI group with PTSD endorsed a significantly greater number of emotional complaints, especially in the RNBI subscales of anxiety and depression. The patients with PTSD also endorsed a significantly greater number of premorbid sequelae in the RNBI emotional composite scale as well as the RNBI premorbid subscales of pain, anxiety and abuse. In sum, PTSD has a negative impact on emotional but not cognitive functioning within individuals suffering from PCD after a mild TBI.

Kognitive Funktionen

Die in mehreren Studien gefundenen kognitiven Störungen bei Tumorpatienten nach Chemotherapie werden zumeist mit der Zytostatikaneurotoxizität assoziiert. In der vorliegenden Arbeit wird der Zusammenhang von Angst, Depression und Posttraumatischer Belastungsstörung mit der kognitiven Leistungsfähigkeit bei Frauen mit Mammakarzinom untersucht. Insgesamt wurden 76 Brustkrebspatientinnen fünf Jahre nach Abschluss der onkologischen Behandlung mit neuropsychologischen Testverfahren sowie mit der Hospital Anxiety and Depression Scale – Deutsche Version (HADS-D) und der Posttraumatic Stress Disorder Checklist – Civilian Version (PCL-C) untersucht: 23 nach Standard- und 24 nach Hochdosistherapie sowie 29 nach Brustoperation und Strahlentherapie als Vergleichsgruppe. Signifikante Zusammenhänge sind vor allem zwischen kognitiven Funktionen und Intrusionssymptomen einer Posttraumatischen Belastungsstörung (PTBS) festzustellen. Bei Patientinnen nach Standardtherapie weisen Intrusionen der PTBS einen moderaten Zusammenhang mit der globalen kognitiven Beeinträchtigung auf. Die Ergebnisse der Studie deuten auf multidimensionale Einfluss- und moderierende Faktoren bei der Entwicklung kognitiver Defizite bei Brustkrebspatientinnen nach onkologischer Therapie hin.
