Show moreBackground: Huntington's disease (HD) is a genetic, neurodegenerative disease. Due to the progressive nature of HD and the absence of a cure, (health-related) quality of life ((HR)QoL) is an important topic. Several studies have investigated (HR)QoL in HD, yet a clear synthesis of the existing literature is lacking to date. We performed a systematic review on self-reported (HR)QoL, and factors and intervention effects associated with (HR)QoL in premanifest and manifest HD gene expansion carriers (pHDGECs and mHDGECs, respectively). Methods: PubMed, EMBASE, Web of Science, and PsycINFO were searched systematically from September 17th, 2021, up to August 11th, 2022. Methodological and conceptual quality of the included studies was assessed with two appraisal tools.Results: 30 out of 70 eligible articles were included. mHDGECs experienced lower (HR)QoL compared to pHDGECs and controls, whereas mixed findings were reported when compared to other neurological diseases. Several factors were associated with (HR)QoL that might contribute to lower (HR)QoL in mHDGECs, including depressive symptoms, physical and psychological symptoms, lower functional capacity, lower support, and unmet needs. Multidisciplinary rehabilitation programs and a respiratory muscle training were beneficial for (HR)QoL in mHDGECs. Discussion: (HR)QoL is experienced differently across the course of the disease. Although (HR)QoL is key for understanding the impact of HD and the effect of symptomatic treatment, there is a need to improve the methodological and conceptual shortcomings that were found in most studies, especially regarding the conceptual clarity when reporting on QoL and HRQoL. Suggestions for strengthening these shortcomings are provided in this review. Show less

Show moreThe thesis reports about the effects of music therapy with patients in the late stage of Huntington's disease. A literature review, a focus group study, a randomized controlled trial, an evaluation for complex interventions and a case report study are integrated in the thesis. The beneficial effects of music therapy could not be proven with the RCT-design and outcome measures that have been used. The beneficial effects of music therapy could not be proven with the RCT-design and outcome measures that have been used in the effect study. This outcome could imply that either music therapy is not effective in HD, or that the chosen study design or the primary endpoints (communication and expressive skills and behavior) were not appropriate to show the effectiveness of music therapy. A process evaluation of the RCT was executed to elucidate the results and to investigate how the study was performed. Show less

Show moreThe general aim of this thesis was to assess the effectiveness of a standardized psychosocial education program. The first studies of this thesis were aimed to assess the effectiveness of the Patient Education Program for Parkinson__s disease (PEPP), as the original program was directed at Parkinson__s disease. Thereafter, it was aimed to assess the program__s feasibility in other diseases. A second step in the thesis was an evaluation of the feasibility of the program adapted to a new disease-specific form for Huntington__s disease (PEP-HD). The third step was to evaluate a generic form of the program in a heterogeneous group of patients with chronic diseases and co-morbid psychiatric problems (PEP-CD). Show less
