Peritraumatic Reactions and Posttraumatic Psychopathology

Abstract

Although not every trauma-exposed individual develops a mental health problem, a considerable proportion experience conditions such as posttraumatic stress disorder, depression, and anxiety disorders. This review aims to examine the relationship between peritraumatic reactions, defined as acute psychological and physiological responses that occur during or immediately after a traumatic event, and posttraumatic stress symptoms as well as related mental health problems. Within this scope, core peritraumatic responses including peritraumatic distress, peritraumatic dissociation, tonic immobility, mental defeat, and peritraumatic somatoform dissociation are discussed. Findings indicate that these reactions are critical determinants of long-term psychological outcomes and can influence the processing of traumatic experiences through their effects on memory encoding, threat appraisal, and emotion regulation mechanisms. In particular, high levels of peritraumatic distress and dissociation may contribute to the persistence of traumatic memories in a fragmented, decontextualized, and intrusive form. Tonic immobility and mental defeat, on the other hand, may intensify symptom severity by reinforcing secondary cognitive and emotional processes such as perceived loss of control, helplessness, shame, and self-blame. At the neurobiological level, alterations in networks involved in emotion regulation and contextual memory, particularly those associated with the amygdala, hippocampus, and prefrontal cortex, are emphasized as potential mechanisms increasing vulnerability to posttraumatic psychopathology. Early assessment of peritraumatic reactions and the development of response-sensitive intervention strategies are therefore crucial for the prevention of trauma-related psychological disorders.

Peritravmatik Tepkiler ve Travma Sonrası Psikopatoloji

Öz

Travmaya maruz kalan her birey bir ruh sağlığı sorunu geliştirmese de, önemli bir kısmı travma sonrası stres bozukluğu, depresyon ve anksiyete bozuklukları gibi sorunlar yaşamaktadır. Bu derleme çalışması, travmatik olay sırasında ya da hemen sonrasında ortaya çıkan ve akut psikolojik ile fizyolojik tepkiler olarak tanımlanan peritravmatik tepkilerin, travma sonrası stres belirtileri ve ilişkili ruh sağlığı sorunları ile olan ilişkisini incelemeyi amaçlamaktadır. Bu gözden geçirme kapsamında peritravmatik sıkıntı, peritravmatik disosiyasyon, tonik hareketsizlik, zihinsel yenilgi ve peritravmatik somatoform disosiyasyon gibi temel peritravmatik tepkiler ele alınmıştır. Bulgular, bu tepkilerin uzun vadeli psikolojik sonuçlar açısından kritik belirleyiciler olduğunu; travmatik yaşantının işlenmesini bellek kodlama süreçleri, tehdit değerlendirmeleri ve duygusal düzenleme mekanizmaları üzerinden etkileyebildiğini göstermektedir. Özellikle yüksek düzeyde peritravmatik sıkıntı ve disosiyasyonun, travmatik anıların daha parçalı, bağlamdan kopuk ve intruzif biçimde sürmesine zemin hazırladığı; tonik hareketsizlik ve zihinsel yenilginin ise kontrol kaybı, çaresizlik, utanç ve kendini suçlama gibi ikincil bilişsel-duygusal süreçleri güçlendirerek belirtilerin şiddetini artırabildiği değerlendirilmektedir. Nörobiyolojik düzeyde, amigdala, hipokampus ve prefrontal korteks başta olmak üzere duygu düzenleme ve bağlamsal bellekle ilişkili ağlarda ortaya çıkabilen değişimlerin, travma sonrası psikopatoloji riskini artıran mekanizmalardan biri olabileceği vurgulanmaktadır. Peritravmatik tepkilerin erken dönemde değerlendirilmesi ve tepki türüne duyarlı müdahalelerin planlanması, travma sonrası psikolojik bozuklukların önlenmesine yönelik stratejilerin geliştirilmesi açısından önem taşımaktadır.
