Nevertheless, there is a dearth of empirically supported interventions addressing family functioning and PTSD. In the Netherlands, it is considered good clinical practice to offer multi-family therapy(MFT) to veteran and refugee families. MFT for traumatized families aims to address the dysfunctional family patterns that have evolved to address the consequences with trauma.Methods: The aim of this study is to generate a common framework for the practical impact and active ingredients of MFT in families confronted with trauma. The Delphi method was used to study the expert opinion of 11 therapists in Dutch expert trauma institutes.Results: The results indicate that MFT is a promising treatment for families dealing with the consequences of trauma. According to experts, positive outcomes include an increased understanding between family members,particularly visible in the de-escalation of conflicts within the family, and improved parenting. One explanation for the effectiveness of MFT with these target groups is its defining feature of therapy with several families.Conclusions: The findings support the importance of considering family relationships and the family context in interventions for traumatized individuals.展开更多

Furthermore, mood has been shown to impact discourse processing. In these studies, a strong expectancy was evoked by a linguistic context. In the present study, a strong expectancy was induced by a visual (non-linguistic) context paired with a sentence. A spatial array was followed by a sentence that matched (□○—The square stands in front of the circle) or mismatched the picture (intra-dimensional mismatch: □○—The square stands behind the circle;extra-dimensional mismatch: □○—The square stands above the circle). The main question was whether mood effects on the processing of visually induced expectancies are similar or different from mood effects on the processing of linguistically induced expectancies. To this aim, we presented conceptual (mis)matches that differed in saliency: intra-dimensional vs. extra-dimensional mismatches which are both reported to elicit an N2b/N400 and P600, reflecting reanalysis. EEG was recorded while participants read for comprehension. Mood (happy vs. sad) was effectively induced by film clips. Neither for N2b/N400 nor for P600, an interaction between mood and match was observed. Thus, in contrast with studies investigating the effects of pure linguistic mismatches (linguistic context paired with unexpected lexical item), mood did not modulate the processing of conceptual mismatches. However, a main effect of match revealed different ERP patterns for the two mismatches. While an increase in N2b/ N400 occurred for the intra-dimensional and extra-dimensional mismatches, a P600 only occurred to the extra-dimensional (more salient) mismatches. This finding is taken as support that being in an emotional state (positive or negative mood) influences processes of reanalysis. That is, when being in an emotional state, a reanalysis (monitoring) process is exclusively triggered by salient mismatches.展开更多

They could also be part of the clinical picture in other cases such as psychosis or mood symptoms secondary to brucellosis or toxoplasmosis. Late-onset neuropsychiatric complications may also occur several years following the infection such as in the case of subacute sclerosing panencephalitis due to measles. Some Infectious diseases may have possible etiological role for major psychiatric disorders, based on yet unconfirmed reports for viral infectious diseases (e.g. Influenza virus and HSV-1) which are thought to have risk for developing schizophrenia and psychosis. Neuropsychiatric adverse effects can occur due to drugs (e.g. mefloquine, interferon-alpha) that are used for treatment of infectious diseases. Psychiatric symptoms can also be reactivated resulting from chronic, complicated and serious infections such as HIV that can lead to depression, anxiety or adjustment disorders, although CNS involvement can also be a possible etiological factor. Patients suffering from primary and severe psychiatric disorders are at increased risk of contracting infection;that is mainly related to high risk behaviors in patients with mania or schizophrenia. It is also important to consider that the co-occurrence of psychiatric symptoms and infection can be incidental (i.e. infectious diseases can occur in psychiatric patients regardless of the above mentioned factors). Early identification of the underlying etiology for organic/secondary psychiatric symptoms is essential for appropriate intervention and early treatment of the primary condition that could be the etiology of psychiatric symptoms so as to avoid unnecessary long-term psychiatric treatment and to avoid complications of possible misdiagnosis or delayed diagnosis of the primary condition.展开更多
