BACKGROUND Many patients with Posttraumatic Stress Disorder (PTSD) feel overwhelmed in situations with high levels of sensory input, as in crowded situations with complex sensory characteristics. These difficulties might be related to subtle sensory processing deficits similar to those that have been found for sounds in electrophysiological studies. (More)

The(More)
BACKGROUND Prevalence rates of child maltreatment (CM) can differ substantially between countries and ethnicities. Reasons, however, are complex and not sufficiently understood. METHOD This epidemiological study examined prevalence and risk factors of various types of CM in a population-based representative sample of native and immigrant adolescents in(More)
BACKGROUND Refugees can suffer many experiences that threaten their trust in others. Although models of refugee mental health have postulated that attachment securities may be damaged by refugee experiences, this has yet to be empirically tested. This study aimed to understand the relationship between the nature of traumatic experiences sustained by(More)

The aim of the study is to explore, which role the interpreters assign to themselves and which role they actually take in the clinical setting. METHODS In the quantitative part of the study, the interpreters evaluated their role in the clinical(More)
OBJECTIVE The case of a schizoaffective patient suffering from a malignant catatonic syndrome following combined lithium-risperidone therapy is explored. METHOD A case report and relevant deliberations regarding pathophysiology of the catatonic dilemma are discussed. CONCLUSIONS There are two critical transitions in the development of a malignant(More)
