AbstractObjectivePosttraumatic stress disorder (PTSD) is reliably associated with reduced brain volume relative to healthy controls, in areas similar to those found in depression. We investigated whether in a PTSD sample brain volumes in these areas were related to reporting specific symptoms of PTSD or to overall symptom severity.MethodStructural MRI scans were obtained from 28 participants diagnosed with PTSD according to DSM-IV-TR. Participants reported the extent of individual PTSD symptoms using the Posttraumatic Diagnostic Scale. Voxel-based morphometry applying the Dartel algorithm implemented within SPM5 was used to identify volumetric changes, related to PTSD total, symptom cluster, and individual symptom scores.ResultsBrain volume was unrelated to overall PTSD severity, but greater reexperiencing scores predicted reduced volumes in the middle temporal and inferior occipital cortices. Increased reports of flashbacks predicted reduced volume in the insula/parietal operculum and in the inferior temporal gyrus.ConclusionThe data illustrate the value of analyses at the symptom level within a patient population to supplement group comparisons of patients and healthy controls. Areas identified were consistent with a neurobiological account of flashbacks implicating specific abnormalities in the ventral visual stream.

OBJECTIVES/GOALS: To explore the severity of posttraumatic stress disorder (PTSD) symptoms in association with hippocampal and amygdala volumes in ICU survivors. We hypothesize that the severity of posttraumatic stress symptoms in ICU survivors is associated with lower volumes of both the hippocampus and amygdala. METHODS/STUDY POPULATION: Secondary analysis of the VISIONS study, a prospective sub-study of the BRAIN-ICU cohort, which included survivors of critical illness. Patients were screened for preexisting PTSD before discharge. The PTSD Checklist Specific (PCL-S) was used at 3 and 12 months to evaluate the ICU as a traumatic experience. A score of >30, indicated significant symptoms of PTSD. A Philips Achieva 3T MRI scanner was used to scan patients at both discharge and 3-month follow-up. To compare median brain volumes at discharge and 3 months for those with and without significant PTSD symptomatology (PCL-S ≥30) at 3 and 12 months, we used a Kruskal-Wallis (KW) equality-of-populations rank test. RESULTS/ANTICIPATED RESULTS: The median age for our sample was 58.5 (52.6, 63.7). One-third of the sample was female, and 90% were Caucasian. Fifty-seven percent of individuals (N = 12) had at least one prior mental health diagnosis, with two having a prior history of PTSD. One third of individuals experienced delirium during their critical illness. At 3-month follow up, there were three patients with PTSD symptomatology and one at 12-month follow up. Median brain volumes (hippocampus or amygdala) did not differ between individuals with or without PTSD symptomatology at either 3 or 12 months (p-values for all tests >0.05). DISCUSSION/SIGNIFICANCE OF IMPACT: Although our study did not reveal significant differences in brain volumes between PTSD patients and non-PTSD patients, sample size is a major limitation and larger scale studies should be undertaken to elucidate possible neurobiological markers of PTSD in ICU survivors.

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.

Traumatische Ereignisse

Traumatische Ereignisse im schulischen Kontext treten vergleichsweise häufig auf. So ist die Bestimmung von Kindern und Jugendlichen, die aktuell und auch zu einem späteren Zeitpunkt einer psychologischen Betreuung bedürfen, im Rahmen der Fürsorgepflicht notwendig. 48 Jugendliche zwischen 12 und 17 Jahren wurden in der Schule zu zwei Messzeitpunkten zur akuten und posttraumatischen Symptomatik sowie zu verschiedenen Risikofaktoren befragt. Verwendet wurde die neu entwickelte Checkliste zur Akuten Belastung (CAB) und die deutsche Version des University of Los Angeles at California Posttraumatic Stress Disorder Reaction Index (UCLA CPTSD-RI). Eine Woche nach dem Ereignis betrug der Anteil klinisch bedeutsamer Belastung 21 % und nach 10 – 15 Wochen 10 %. Ein mittlerer Zusammenhang zwischen akuter und posttraumatischer Belastung konnte nachgewiesen werden. Als bedeutsame Risikofaktoren für die Entwicklung einer posttraumatischen Belastung stellten sich der Konfrontationsgrad, peritraumatisch erlebte Angst sowie akute Beeinträchtigung heraus. Im Kontext der Betreuung betroffener Jugendlicher nach traumatischen Ereignissen sollte den Risikofaktoren mehr Beachtung geschenkt werden.
