ABSTRACT

Background: Posttraumatic stress disorder (PTSD) is considered an independent risk factor for dementia. Despite the (clinical) evidence that PTSD is associated with neuropsychiatric symptoms in people with dementia, studies on its prevalence and clinical manifestation are limited, and their quality is affected by the lack of a structured method to diagnose PTSD in this population. The primary aim of the current study is to validate the ‘TRAuma and DEmentia’ interview as a diagnostic tool for PTSD in people with dementia and to test feasibility of EMDR treatment for people with PTSD and dementia.

Methods: This prospective multi-centre study is divided into two parts. In study A, 90 participants with dementia will be included to test the criterion validity, inter-rater reliability and feasibility of the ‘TRAuma and DEmentia’ interview. In study B, 29 participants with dementia and PTSD will receive eye movement desensitisation and reprocessing therapy by a trained psychologist, and 29 participants with dementia and PTSD will be placed on the waiting list control group.

Conclusion: This study aims to improve the diagnostic process of PTSD and to assess the effects of eye movement desensitisation and reprocessing treatment in people with dementia living in Dutch care facilities.

HIGHLIGHTS

  • This study protocol describes a two-part study on posttraumatic stress disorder in people with dementia in Dutch care facilities.

  • The primary aim of the study is to validate the ‘TRAuma and DEmentia’ interview as a diagnostic tool for posttraumatic stress disorder in people with dementia.

  • This study aims to test the feasibility of an evidence-based treatment for people with dementia and posttraumatic stress disorder in the form of eye movement desensitisation and reprocessing therapy.

Antecedentes: El trastorno de estrés postraumático (TEPT) es considerado un factor de riesgo independiente para la demencia. A pesar de la evidencia (clínica) de que el TEPT está asociado con síntomas neuropsiquiátricos en personas con demencia, los estudios sobre su prevalencia y manifestación clínica son limitados, y su calidad se ve afectada por la falta de un método estructurado para diagnosticar el TEPT en esta población. El objetivo principal del presente estudio es validar la entrevista ‘TRAuma and Dementia’ como herramienta de diagnóstico para el trastorno de estrés postraumático en personas con demencia y probar la viabilidad del tratamiento EMDR para personas con TEPT y demencia.

Métodos: Este estudio prospectivo multicéntrico se divide en dos partes. En el estudio A, se incluirán 90 participantes con demencia para probar la validez de criterio, la confiabilidad entre evaluadores y la viabilidad de la entrevista ‘TRAuma and Dementia’. En el estudio B, 29 participantes con demencia y trastorno de estrés postraumático recibirán terapia de reprocesamiento y desensibilización por movimientos oculares por parte de un psicólogo capacitado, y 29 participantes con demencia y trastorno de estrés postraumático se incluirán en el grupo de control de lista de espera.

Conclusión: Este estudio tiene como objetivo mejorar el proceso de diagnóstico del TEPT y evaluar los efectos del tratamiento de reprocesamiento y desensibilización por movimientos oculares en personas con demencia que viven en centros de atención holandeses.
