Traumagedächtnis bei Kindern mit Posttraumatischer Belastungsstörung
Eine kritische Bestandsaufnahme
Abstract
Das Gedächtnis spielt eine wichtige Rolle bei der Entstehung und Behandlung von Posttraumatischer Belastungsstörung (PTBS). Die vorliegende Überblicksarbeit beschäftigt sich mit der Frage nach dem empirischen Nachweis von traumabezogenen Gedächtnisstörungen im Kindesalter. Die bisherigen Untersuchungen zeigen ein heterogenes Bild. Es gibt Hinweise auf eine Beeinträchtigung der Hirnreifungsprozesse sowie der Erinnerungsqualität bei Kindern und Jugendlichen mit PTBS. Jedoch im Gegensatz zu Befunden im Erwachsenenalter wiesen traumatisierte Kinder ein größeres Hippocampusvolumen im Vergleich zur Kontrollgruppe auf. Die Zusammenschau der Befunde macht den großen Bedarf an weiterführenden Untersuchungen deutlich.
The memory processes play an important role in understanding the development and treatment of posttraumatic stress disorder (PTSD). This review critically examines the empirical evidence concerning the trauma-memory argument in children. The studies show a mixed picture. There are some indications of adverse brain development and poor quality of memory in children and adolescents with PTSD. However, in contrast to adults, children with PTSD showed greater hippocampal volumes compared with control subjects. More research is needed before meaningful conclusions can be drawn about the relation between traumatic memory and PTSD in children.
