The clinical effectiveness of a self-management intervention for patients with persistent depressive disorder and their partners/caregivers: results from a multicenter, pragmatic randomized controlled trial. Trials 2024; 25:187. [PMID: 38481289 PMCID: PMC10938802 DOI: 10.1186/s13063-024-08033-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 03/04/2024] [Indexed: 03/17/2024] Open
Abstract
BACKGROUND Persistent depressive disorder (PDD) is prevalent and debilitating. For patients with PDD, psychiatric rehabilitation using self-management interventions is advised as the next therapeutic step after multiple unsuccessful treatment attempts. The "Patient and Partner Education Program for All Chronic Diseases" (PPEP4All) is a brief, structured self-management program that focuses on functional recovery for patients and their partners/caregivers. In chronic somatic disorder populations, PPEP4All has already been shown to be clinically effective. We examined whether PPEP4All adapted for PDD (PPEP4All-PDD, nine weekly group or individual sessions) is also clinically effective for adults/elderly with PDD and their partners/caregivers compared to care-as-usual (CAU) in specialized mental healthcare. METHODS In this mixed-method multicenter pragmatic randomized controlled trial, 70 patients with PDD and 14 partners/caregivers were allocated to either PPEP4All-PDD (patients, n = 37; partners/caregivers, n = 14) or CAU (patients, n = 33; partners/caregivers, not included) and completed questionnaires at 0, 3, 6, and 12 months regarding depressive symptoms, psychopathology, psychosocial burden, mental resilience, and happiness/well-being. Qualitative data were collected regarding treatment satisfaction. Data were analyzed using mixed model analyses and an intention-to-treat (ITT) approach. RESULTS There was no statistically significant difference in any outcome regarding clinical effectiveness between PPEP4All-PDD and CAU. Subgroup analysis for depressive symptoms did not show any interaction effect for any subgroup. Although 78% of participants recommended PPEP4All-PDD, there was no difference in treatment satisfaction between PPEP4All-PDD (score = 6.6; SD = 1.7) and CAU (score = 7.6; SD = 1.2), p = 0.06. CONCLUSION Although depressive symptoms did not improve relative to CAU, this only confirmed that treatment for patients with treatment-resistant PDD should move from symptom reduction to functional recovery. Also, functional recovery may be reflected in other outcomes than psychosocial burden, such as self-empowerment, in patients with treatment-resistant PDD. Future research on PPEP4All-PDD could focus on a longer-term program and/or online program that may also be offered earlier in the treatment process as an empowerment intervention.

Abstract
OBJECTIVES This study aims to provide more insight into possible barriers and facilitators caregivers of people with Huntington's disease (HD) encounter, and what their needs and wishes are regarding a remote support program. METHODS In total, 27 persons participated in four focus group interviews. Eligible participants were caregivers (n = 19) of a person with HD, and healthcare professionals (n = 8) involved in HD care. Qualitative data were analyzed by two researchers who independently performed an inductive content analysis. RESULTS Four major themes emerged from the data, including (1) a paradox between taking care of yourself and caring for others; (2) challenges HD caregivers face in daily life, including lack of HD awareness, taboo and shame, feelings of loneliness, concerns about heredity and children, and coping with HD symptoms; (3) facilitators in the caregiving process, including a social network, professional support, openness, talking in early phases, and daily structure; (4) needs regarding a support program. CONCLUSION These insights will be used to develop a remote support program for HD caregivers, using a blended and self-management approach. Newly developed and tailored support should be aimed at empowering caregivers in their role and help them cope with their situation, taking into account barriers and facilitators.

Abstract
INTRODUCTION Little is known about reducing the challenges for caregivers and patients with Huntington's disease (HD). HD creates behavioral disturbances, cognitive decline, and motor disorder progression over the lifetime requiring some individuals to need long-term facility care. AIMS There are concerns about safety and confidence of employees caring for residents with HD. METHODS Nursing staff, administrators, and auxiliary employees were recruited from a long-term care (LTC) facility in rural Iowa, from July 2020 to August 2020. A de-escalation training intervention was delivered. The 1-day intervention included resident behaviors, planning and safety, teamwork, communication, and included role play and simulation. A pre- and post-survey measured confidence and competence in caring for people with HD before and after a training intervention. A resident medical record audit explored challenging behaviors before and after the training intervention. RESULTS Of 25 participants, six were registered nurses/licensed practical nurses (RNs/LPNs; 24%), four administrators (16%), eight nursing assistants (32%), and seven auxiliary employees (28%). There was improvement in employees perceived safety (33.3%), co-workers enjoyment working with HD residents (54%), understanding symptoms of HD (44.4%), confidence in job abilities (21.0%), and confidence in ability to care for patients with HD (26.3%). A medical record audit showed decreased documentation of resident aggression and care refusal post-intervention. CONCLUSIONS These findings suggest de-escalation training in LTC facilities increased perception of job safety, co-workers' enjoyment, understanding HD symptoms, confidence in ability to care for patients with HD, and decreased resident agitation and care refusal.

Abstract
People with Huntington's disease (HD) face difficult emotional and practical challenges throughout their illness, including in the pre-symptomatic stage. There are, however, extremely limited psychosocial interventions adapted to or researched for HD. We adapted and piloted an 8-week mindfulness-based stress reduction (MBSR) program in people with pre-symptomatic HD to determine if the program (i) was feasible and acceptable to participants, (ii) resulted in increased mindfulness understanding and skills, and (iii) led to improved psychological adjustment. Quantitative measures of mindfulness, emotion regulation, mood, and quality of life were administered pre and post the MBSR program and at 3-month follow-up. Measures of mindfulness practice and session clarity were administered weekly. Qualitative participant feedback was collected with a post-program interview conducted by independent clinicians. Seven participants completed the 8-week course. The program's feasibility and acceptability was supported by excellent retention and participation rates and acceptable rates of home practice completion. In addition, qualitative feedback indicated participant satisfaction with the program structure and content. Two core mindfulness skills (observing and non-judgment) showed significant improvement from pre- to post-assessment. Participant qualitative feedback indicated increased confidence and capacity to use mindfulness techniques, particularly in emotionally challenging situations. Participant questionnaire data showed good psychological adjustment at baseline, which did not change after treatment. Psychological benefits of the program identified in qualitative data included fewer ruminations about HD, reduced isolation and stigma, and being seen by others as calmer. These findings justify expansion of the program to determine its efficacy in a larger, controlled study.

Quality of life, health-related quality of life, and associated factors in Huntington's disease: a systematic review. J Neurol 2023; 270:2416-2437. [PMID: 36715747 PMCID: PMC10129943 DOI: 10.1007/s00415-022-11551-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 12/23/2022] [Accepted: 12/24/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND 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.

Abstract
People who are aware that they are gene-positive for Huntington's disease (HD) may face an array of personal, relationship, social, financial and employment challenges prior to the onset of the disease. These challenges have been associated with increased psychological problems such as anxiety and depression. Information and support for people with pre-symptomatic HD is indicated, but there is a scarcity of research and service models to inform psychological interventions. We trialled an intervention strategy involving psychoeducation forums designed specifically for pre-symptomatic HD. In phase I of the study, we asked people with pre-symptomatic HD to identify their uppermost needs for information. Phase II involved the delivery of this information via a series of forums. The forums also provided an opportunity for interaction among the participants. Three forums were attended by 88 people with pre-symptomatic HD and significant others. Analysis of post-forum feedback questionnaires indicated high levels of satisfaction with the forums' structure, content and relevance, and notably, the pre-symptomatic specificity of focus. Additional qualitative data from recordings of forum discussion groups revealed that participants greatly valued the opportunity to meet similar others, and share their concerns and strategies for addressing these concerns. There was an abundance of requests for more forums on a wide range of relevant topics. It is recommended that this model of intervention may be of value for implementation in other HD services or community groups.

Abstract
BACKGROUND After regular treatment, patients with persistent depressive disorder (PDD) may remain in specialized psychiatric outpatient care without achieving remission. Lacking other options, these patients often receive long-term, non-protocolized care as usual (CAU) that does not involve the partner/caregiver of the patient. Although the revised depression treatment guidelines suggest focusing on psychiatric rehabilitation and self-management as the next treatment step for PDD, an evidence-based cost-effective self-management protocol for PDD is lacking. This study investigates the "Patient and Partner Education Program for All Chronic Illnesses" (PPEP4All) as a brief self-management protocol that could lead to lower costs, higher quality of life, and less disease burden in PDD patients and their partners/caregivers. METHODS Presented is the rationale and methods of a multicenter pragmatic randomized controlled trial to evaluate the clinical efficacy and cost-effectiveness of PPEP4All for patients with PDD and their partners/caregivers. In accordance with current recommendations, a mixed methods research approach is used with both quantitative and qualitative data. A total of 178 eligible outpatients with PDD and their partners/caregivers are recruited and randomized to either PPEP4All or CAU. Those assigned to PPEP4All receive nine weekly self-management sessions with a trained PPEP4All therapist. Primary and secondary outcome measurements are at 0, 3, 6, and 12 months. DISCUSSION This project will result in the implementation of a self-management intervention for patients with PDD, meeting an urgent need in mental healthcare. Using PPEP4All can optimize the quality and efficiency of care for both patients with PDD and their partners/caregivers. TRIAL REGISTRATION Netherlands Trial Register Identifier NTR5973 .

Abstract
BACKGROUND Little is known about the benefits, and barriers and facilitators to providing psychosocial support to caregivers to a loved one with a rare disease. OBJECTIVE The aim of our scoping review was to map evidence on (1) perceived benefits and (2) barriers and facilitators of establishing and maintaining services. METHODS The CINAHL and PubMed databases were searched in December 2018. Qualitative and quantitative studies in any language that described perceived or tested benefits of participating in psychosocial interventions for caregivers, or the barriers and facilitators of providing these interventions, were eligible. RESULTS Thirty-four studies were included. Interventions were behavioural or psychological, supportive, educational, or multicomponent. All included studies reported on the benefits of participating in psychosocial interventions; 14 (41%) studies also reported on facilitators and 19 (56%) reported on barriers. Benefits that were most commonly found included statistically significant improvements in emotional states (e.g. stress) and caregiver burden and narrative reports of intervention helpfulness. Statistically significant improvements in mental health outcomes (e.g. depression symptoms) were rarely detected. Four themes for facilitators were identified, including intervention characteristics, intervention delivery characteristics, provision of necessary resources, and support provided outside of the intervention. Four barrier themes were also identified: misalignment of intervention to caregiver needs, inability to make time for intervention, practical barriers, emotional barriers. CONCLUSIONS Psychosocial interventions for caregivers to a loved one with a rare disease may be helpful in reducing stress, burden, and feelings of isolation among caregivers. Future research should design interventions for caregivers that take into account facilitators and barriers to establishing and maintaining such interventions.

Abstract
Neuropsychiatric manifestations of Huntington's disease (HD) can present years before motor symptoms. Nurses with specialized training provide superior care for HD patients, but HD exposure in nursing education is limited. Here we aimed to describe the historical neuropsychiatric burden in 50 HD patients and discuss implications for psychiatric nurses. Fifty patients with HD were assessed by a board-certified psychiatrist and completed surveys about symptoms, social history, medication use, and quality of life outcomes. Descriptive statistics were used to summarize patient characteristics, and correlation analyses assessed the relationships between neuropsychiatric symptoms and quality of life outcomes. Most patients (72%) reported a history of neuropsychiatric symptoms prior to their HD diagnosis. Prodromal anger/irritability was most common (52%), though few patients received treatment for this. Anxiety was the most common current symptom (78%), yet 40% of patients had never been prescribed an SSRI. Anxiety was associated with poorer patient-reported quality of life outcomes (p < .01). HD patients in this sample experienced frequent, early-onset neuropsychiatric symptoms. In coming years, psychiatric nurses in community settings will be more likely to encounter gene-positive HD patients before they develop motor symptoms. Psychiatric nurses can address identified gaps through enhanced screening and encouraging early intervention in those at risk.

Abstract
BACKGROUND Psychological difficulties such as anxiety, depression, and irritability are common in Huntington's disease, even for premanifest individuals. However, very little evidence exists of psychological approaches to manage this distress. We have conducted a feasibility study with an embedded qualitative component to investigate the possibility of using mindfulness-based cognitive therapy (MBCT) and present here the findings from the qualitative data. OBJECTIVE To investigate the experience of premanifest individuals learning and practising mindfulness through completing a course of MBCT. METHODS Twelve premanifest individuals completed a course of MBCT and attended three follow up reunion meetings over the following year. Eleven participants agreed to be interviewed post-course and ten participants one year post-course about their experience of the course and any impact on their lives. Seven participants nominated a friend or relative (supporter) to be involved in the research, of whom six agreed to be interviewed post-course and two at one year about the impact of the course on the participants. Data were analysed using reflexive thematic analysis. RESULTS Four themes were constructed from the data: 1) A meeting of minds: the group facilitating learning and support; 2) Mindfulness is hard, but enables more effective emotional management; 3) Mindfulness can change the relationship with self and others; and 4) Benefiting from mindfulness: the importance of persistence. CONCLUSION The participants who completed the course found it beneficial. Some participants reported reductions in psychological distress, a greater sense of calm and better emotion regulation, with some of these positive changes also noticed by supporters. MBCT is worthy of further investigation for this population.

Maximizing placebo response in neurological clinical practice. INTERNATIONAL REVIEW OF NEUROBIOLOGY 2020; 153:71-101.

Abstract
The placebo effect is a widely recognized phenomenon in clinical research, with a negative perception that it could hide the "true" drug effect. In clinical care its positive potential to increase known drug effects has been neglected for too long. The placebo and nocebo responses have been described in many neurologic disorders such as Parkinson's, Huntington's and Alzheimer's diseases, restless leg syndrome, tics, essential tremor, dystonia, functional movement disorders, neuropathic pain, headaches, migraine, amyotrophic lateral sclerosis, myasthenia gravis, chronic inflammatory demyelinating polyneuropathy, multiple sclerosis and epilepsy. Knowledge regarding placebo mechanisms and their consequences on clinical outcome have greatly improved over the last two decades. This evolution has led to reconsiderations of the importance of placebo response in the clinic and has given several clues on how to improve it in daily practice. In this chapter, we first illustrate "why," e.g. the reasons (relevance to clinical practice, help in differential diagnosis/treatment of psychogenic movements, clinical impact, proven neurobiological grounds, health economic potential), and "how," e.g. the means (increase patients' knowledge, increase learning, improve patient-doctor relationship, increase Hawthorne effect, increase positive/decrease negative expectations (the Rosenthal effect), personalize placebo response), the placebo should be maximized (and nocebo avoided) in neurological clinical practice. Future studies regarding more specific neurobiological mechanisms will allow a finer tuning of placebo response in clinical practice. The use of placebo in clinical practice raises ethical issues, and a recent expert consensus regarding placebo use in the clinic is a first step to future guidelines necessary to this field.

Therapeutic patient education in Alzheimer's disease and related disorders: Clinical experience and perspectives. Rev Neurol (Paris) 2020; 176:200-207. [PMID: 31916975 DOI: 10.1016/j.neurol.2019.07.028] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2019] [Revised: 06/17/2019] [Accepted: 07/15/2019] [Indexed: 01/15/2023]
Abstract
Therapeutic patient education (TPE) is the process by which health professionals impart information to help patients self-manage their chronic disease: it is an essential part of treatment of long-term diseases and conditions. Memory loss and other cognitive disorders are usually considered as obstacles to TPE for patients with Alzheimer's disease or related disorders (ADRD). Over 100 patients with different forms of ADRD and caregivers have benefited from TPE programs since 2011 at the Limoges University Clinical and Research Memory Center. Participants report better understanding of the disease and improved relationships. TPE may prevent anxiety and depression in patient and in caregivers, and reduce burden of caregivers. General guidelines and perspectives for TPE in ADRD are outlined.

Abstract
BACKGROUND Although Huntington's disease (HD) can cause a wide range of psychological difficulties, no review has ever been carried out on the range of psychological interventions adopted with this population. OBJECTIVE To scope the literature on psychological interventions for psychological difficulties in people affected by HD. METHODS A systematic scoping review was performed across MEDLINE, PsycINFO, CINAHL, Academic Search Ultimate, and Cochrane Library up to 1 March 2020. RESULTS From an initial return of 1579 citations, a total of nine papers were considered eligible for review. These included a qualitative investigation, three case studies, two case series, two uncontrolled pretest-posttest designs, and only one randomised control trial (RCT). Despite the wide range of psychological difficulties which can be experienced by people affected by the HD gene expansion, the adopted interventions only accounted for five main psychological outcomes (anxiety, apathy, depression, irritability, and coping). Further discussion and suggestions for future research are provided for each outcome. CONCLUSION The current literature on psychological interventions in people affected by HD is extremely limited both in terms of methods and addressed clinical outcomes. Consequently, no conclusions can be offered yet as to which psychological therapy may help this population. As further more comprehensive research is urgently needed for this group, the ultimate aim of the present review is to act as a call to arms for HD researchers worldwide to help shed light on the most effective way to translate psychological theory into practice for the benefit of people affected by HD.

Improving follow up after predictive testing in Huntington's disease: evaluating a genetic counselling narrative group session. J Community Genet 2019; 11:47-58.

Abstract
Recently updated Huntington’s disease (HD) predictive testing guidelines emphasise clinicians’ responsibility to facilitate emotional support following testing, regardless of the result. Yet models of post-test counselling support are poorly defined. Moreover, it is unclear how these might be best delivered. In this project, a genetic counsellor and clinical psychologist developed standalone group sessions using collective narrative practices for individuals post-predictive testing. Here we present an evaluation of the experiences of one group of six people who have tested mutation positive for HD and remain pre-symptomatic. Two partners also attended the session. Observations, evaluation forms and telephone interviews were used in data collection. Interview data was available from five mutation-positive individuals and one partner. Qualitative data were analysed using a thematic framework approach. Responses were overwhelmingly positive, emphasising the importance of a specifically arranged time and space to share experiences in a structured way. This was typically the first time participants had spoken openly with someone in their situation. Narrative facilitation of discussion encouraged participants to re-discover their strengths and resiliences, with similar experiences being discovered through connections with others. The evaluation was successful in implementing group narrative interventions as part of the predictive test counselling support for Huntington’s disease. Participants suggested that the approach could be extended and adopted for other genetic conditions.

Abstract
OBJECTIVES This study sought to investigate how people who had tested positive for the Huntington's disease (HD) gene mutation understood and experienced psychological distress and their expectations of psychological therapy. DESIGN A qualitative methodology was adopted involving semi-structured interviews and interpretative phenomenological analysis (IPA). METHOD A total of nine participants (five women and four men) who had opted to engage in psychological therapy were recruited and interviewed prior to the start of this particular psychological therapeutic intervention. Interviews were transcribed verbatim and analysed using IPA whereby themes were analysed within and across transcripts and classified into superordinate themes. RESULTS Three superordinate themes were developed: Attributing psychological distress to HD: 'you're blaming everything on that now'; Changes in attributions of distress over time: 'in the past you'd just get on with it'; and Approaching therapy with an open mind, commitment, and hope: 'a light at the end of the tunnel'. CONCLUSION Understandings of psychological distress in HD included biological and psychological explanations, with both often being accepted simultaneously by the same individual but with biomedical accounts generally dominating. Individual experience seemed to reflect a dynamic process whereby people's understanding and experience of their distress changed over time. Psychological therapy was accepted as a positive alternative to medication, providing people with HD with hope that their psychological well-being could be enhanced. PRACTITIONER POINTS People with the Huntington's disease gene mutation have largely biomedical understandings of their psychological distress. This largely biomedical understanding does not, however, preclude them for being interested in the potential gains resulting from psychological therapy. The mechanisms of psychological therapy should be explained in detail before therapy and explored along with current attributions of distress.

Abstract
CONTEXT Patients with pituitary disease report impairments in Quality of Life (QoL) despite optimal biomedical care. Until now, the effects of a self-management intervention (SMI) addressing psychological and social issues for these patients and their partners have not been studied. OBJECTIVE To examine the effects of a SMI i.e. Patient and Partner Education Programme for Pituitary disease (PPEP-Pituitary). DESIGN AND SUBJECTS A multicentre randomized controlled trial included 174 patients with pituitary disease, and 63 partners were allocated to either PPEP-Pituitary or a control group. PPEP-Pituitary included eight weekly sessions (90 min). Self-efficacy, bother and needs for support, illness perceptions, coping and QoL were assessed before the intervention (T0), directly after (T1) and after six months (T2). Mood was assessed before and after each session. RESULTS Patients in PPEP-Pituitary reported improved mood after each session (except for session 1). In partners, mood only improved after the last three sessions. Patients reported higher self-efficacy at T1 (P = 0.016) which persisted up to T2 (P = 0.033), and less bother by mood problems directly after PPEP-Pituitary (P = 0.01), but more bother after six months (P = 0.001), although this increase was not different from baseline (P = 0.346). Partners in PPEP-Pituitary reported more vitality (P = 0.008) which persisted up to T2 (P = 0.034). At T2, partners also reported less anxiety and depressive symptoms (P ≤ 0.014). CONCLUSION This first study evaluating the effects of a SMI targeting psychosocial issues in patients with pituitary disease and their partners demonstrated promising positive results. Future research should focus on the refinement and implementation of this SMI into clinical practice.

Abstract
Phenotypic manifestations of Huntington disease (HD) can be detected at least 15 years prior to the time when a motor diagnosis is given. Advances in clinical care and future research will require consistent use of HD definitions and HD premanifest (prodromal) stages being used across clinics, sites, and countries. Cognitive and behavioral (psychiatric) changes in HD are summarized and implications for ongoing advancement in our knowledge of prodromal HD are suggested. The earliest detected cognitive changes are observed in the Symbol Digit Modalities Test, Stroop Interference, Stroop Color and Word Test-interference condition, and Trail Making Test. Cognitive changes in the middle and near motor diagnostic stages of prodromal HD involve nearly every cognitive test administered and the greatest changes over time (i.e., slopes) are found in those prodromal HD participants who are nearest to motor diagnosis. Psychiatric changes demonstrate significant worsening over time and remain elevated compared with healthy controls throughout the prodromal disease course. Psychiatric and behavior changes in prodromal HD are much lower than that obtained using cognitive assessment, although the psychiatric and behavioral changes represent symptoms most debilitating to independent capacity and wellness.

Abstract
Changes in mental state and behaviour have been acknowledged in Huntington's disease since the original monograph in 1872 provided evidence of disinhibition and impaired social cognition. Behavioural problems can manifest before obvious motor symptoms and are frequently the most disabling part of the illness. Although pharmacological treatments are used routinely for psychiatric difficulties in Huntington's disease, the scientific evidence base for their use is somewhat sparse. Moreover, effective treatments for apathy and cognitive decline do not currently exist. Understanding the social cognitive impairments associated with Huntington's disease can assist management, but related therapeutic interventions are needed. Future research should aim to design rating scales for behaviour and mental state in Huntington's disease that can detect change in clinical trials. Generally, communication and understanding of behaviour and mental state in Huntington's would be enhanced by a clear conceptual framework that unifies ideas around movement, cognition, emotion, behaviour, and mental state, reflecting both the experience of the patient and their underlying neuropathology.

Abstract
BACKGROUND REGISTRY is the largest European observational study of Huntington's disease (HD). The Leiden University Medical Center (LUMC) in The Netherlands is the largest recruiting site. OBJECTIVE The aim of this paper is to give an overview of the baseline characteristics of all Leiden participants from the start of the study in 2005 until the close of REGISTRY at the LUMC in September 2014. METHODS The Leiden cohort is described in two different ways: CAG repeat length and presence of motor signs. RESULTS Division into groups based on prolonged CAG length revealed that the cohort consists of 4 intermediate - (27-35 CAG), 22 reduced penetrance - (36-39 CAG), 465 full penetrance - (>39 CAG) and 60 control participants (<27 CAG). The second way of dividing the participants based on present or absent of motor signs, showed that 170 pre-motormanifest - and 317 motormanifest participants were enrolled. CONCLUSION The Leiden REGISTRY cohort at baseline is mainly characterized by full penetrance gene expansion carriers who have been clinically diagnosed with HD but who remain relatively functionally independent. For the majority of these participants, disease onset was based on motor signs followed by psychiatric and cognitive signs.

Abstract
INTRODUCTION Depression and anxiety are common in Huntington's disease, a genetic neurodegenerative disorder. There is a need for measurement tools of mood to be validated within a Huntington's disease population. The current study aimed to analyze the factor structure of the Hospital Anxiety and Depression Scale in Huntington's disease. METHODS Data from the European Huntington's Disease Network study REGISTRY 3 were used to undertake a factor analysis of the scale among a sample of 492 Huntington's disease mutation carriers. The sample was randomly divided into two equal subsamples and an exploratory factor analysis conducted on the first subsample suggested a two-factor interpretation, using eight of the items. A confirmatory factor analysis was then performed to test six possible models for goodness of fit. RESULTS A bifactor model, with all items loading onto a general distress factor, with two group factors, comprising four depression and four anxiety items, provided the best fit of the data. The salience of loadings on the bifactor model suggested that loadings were high on the general factor (accounting for 64% of the variance) and low on the group factors (21% for anxiety and 15% for depression). CONCLUSIONS The findings suggest that eight items from the scale perform well among the sample. Consistent with recent developments in modeling the Hospital Anxiety and Depression Scale, a bifactor interpretation for an eight-item version outperformed other extant models. Our findings provide support for an eight-item version of the scale to be used as a measure of general distress within Huntington's disease populations.
