Fluctuating salience in those living with genetic risk of motor neuron disease: A qualitative interview study

BACKGROUND

Motor neuron disease (MND) (also known as amyotrophic lateral sclerosis) is a life-limiting neurodegenerative condition. In up to 20% of people with MND, a pathogenic variant associated with autosomal dominant inheritance can be identified. Children of people carrying a pathogenic variant have a 50% chance of inheriting this and a higher, although harder to predict, chance of developing the disease compared to the general adult population. This paper explores the experience of living with the genetic risk of MND.

METHODS

We undertook a UK-based interview study with 35 individuals, including: 7 people living with genetically-mediated forms of MND; 24 asymptomatic relatives, the majority of whom had an increased risk of developing the disease; and 4 unrelated partners.

RESULTS

We explore how individuals make sense of genetic risk, unpacking the interplay between genetic knowledge, personal perception, experiences of the disease in the family, age and life stage and the implications that living with risk has for different aspects of their lives. We balance an emphasis on the emotional and psychological impact described by participants, with a recognition that the salience of risk fluctuates over time. Furthermore, we highlight the diverse strategies and approaches people employ to live well in the face of uncertainty and the complex ways they engage with the possibility of developing symptoms in the future. Finally, we outline the need for open-ended, tailored support and information provision.

CONCLUSIONS

Drawing on wider literature on genetic risk, we foreground how knowledge of MND risk can disrupt individuals' taken-for-granted assumptions on life and perceptions of the future, but also its contextuality, whereby its relevance becomes more prominent at critical junctures. This research has been used in the development of a public-facing resource on the healthtalk.org website.

PATIENT OR PUBLIC CONTRIBUTION

People with experience of living with genetic risk were involved throughout the design and conduct of the study and advised on aspects including the topic guide, sampling and recruitment and the developing analysis. Two patient and public involvement contributors joined a formal advisory panel.

Factors associated with grief in informal carers of people living with Motor Neuron Disease: A mixed methods systematic review

The purpose of this mixed methods systematic review was to identify factors associated with anticipatory grief, post-death grief, and prolonged grief in informal carers of people living with Motor Neuron Disease (MND) to inform future research and practice. Six electronic databases were searched and two quantitative and eight qualitative studies were identified. Five overarching themes were generated through thematic synthesis. The findings suggest that there are factors that may affect different grieving processes. It might be particularly important to target some factors prior and after the death of the person living with MND such as the knowledge about the progression of the disease, changes in relationships, anxiety and depressive symptoms of carers, and planning for death of the care recipient. Factors that may affect all three grieving processes were also identified such as negative experiences of caregiving, experiences of losses, end of life and psychological support, and emotional avoidance coping.

Exploring clinical management of cognitive and behavioural deficits in MND. A scoping review

OBJECTIVES

Little is known about how cognitive and behavioural decline in MND is managed clinically. This review aimed to summarise clinical management approaches of cognitive and behavioural decline in MND reported in peer-reviewed and grey literature.

METHODS

A scoping review was conducted across Embase, Medline, Psychinfo and Emcare in October 2022. Grey literature was also searched across Google Scholar and Google in October 2022.

RESULTS

A total of N = 26 studies and 8 documents were included. Thematic analysis revealed six key areas of clinical management: i. Assessment, ii. Education, iii. Advance Care Planning, iv. Adaptation of Care Plan, v. Communication and vi. Carer Support.

CONCLUSIONS

The literature on management of cognitive and behavioural decline in MND is sparse. Most peer-reviewed literature consists of expert commentary and there is a lack of primary data to guide practitioners and families on how to manage cognitive and behavioural change in MND.

PRACTICE IMPLICATIONS

Determining as early as practicable the presence of cognitive and behavioural changes in pwMND will enable practitioners to make adaptations to communication, provide education and supported decision-making for forward planning. This will enable individualised care, planned in partnership with families with MND, which incorporates personal needs and wishes.

Requested withdrawal of gastrostomy feeding in motor neurone disease

NICE (National Institute for Health & Care Excellence) guidance recommends that healthcare professionals with expertise in palliative care should be an integral part of the multidisciplinary team in managing patients with motor neuron disease (MND). Those in the poorest prognostic group may benefit from early referral to help manage rapidly progressive symptoms, psychological distress and offer additional support with complex decision-making and early robust advance care planning. Patients frequently develop dysphagia and gastrostomy feeding can be used to prolong survival and improve quality of life. As the disease progresses patients may request withdrawal of life-sustaining treatment such as gastrostomy feeding; however, a literature search found no evidence or guidance on how best to facilitate this. We present the case of a patient with MND admitted to the hospice inpatient unit requesting withdrawal of gastrostomy feeding, outline the challenges and need for further consensus guidelines to inform practice.

Methods for informing people with amyotrophic lateral sclerosis/motor neuron disease of their diagnosis

BACKGROUND

Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), causes increasing physical impairment and disability. People with ALS/MND face huge physical challenges, and the diagnosis can be a source of great psychological distress for both people with ALS/MND and their carers. In such a context, how news of the diagnosis is broken is important. At present, there are no systematic reviews of methods for informing people with ALS/MND of their diagnosis.

OBJECTIVES

To examine the effects and effectiveness of different methods for informing people of a diagnosis of amyotrophic lateral sclerosis/motor neuron disease (ALS/MND), including effects on the person's knowledge and understanding of their disease, its treatment, and care; and on coping and adjustment to the effects of ALS/MND, its treatment, and care.

SEARCH METHODS

We searched the Neuromuscular Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, and two trials registers (February 2022). We contacted individuals or organisations to locate studies. We contacted study authors to obtain additional unpublished data.

SELECTION CRITERIA

We planned to include randomised controlled trials (RCTs) and quasi-RCTs of techniques for informing people with ALS/MND of their diagnosis. We planned to include adults (aged 17 years or over) with ALS/MND, according to the El Escorial criteria.

DATA COLLECTION AND ANALYSIS

Three review authors independently reviewed the results of the search to identify RCTs, and three review authors identified non-randomised studies to include in the discussion section. We planned that two review authors would independently extract data, and three would assess the risk of bias in any included trials.

MAIN RESULTS

We did not identify any RCTs that met our inclusion criteria.

AUTHORS' CONCLUSIONS

There are no RCTs that evaluate different communication strategies for breaking the bad news for people diagnosed with ALS/MND. Focused research studies are needed to assess the effectiveness and efficacy of different communication methods.

The impact of communication on healthcare involvement for people living with motor neurone disease and their carers: A longitudinal qualitative study

BACKGROUND

Communication and cognitive impairments are known barriers to shared decision-making. Most people diagnosed with motor neurone disease (MND) will develop a motor speech impairment over the disease course. Some will develop cognitive, linguistic or behavioural disturbance. Despite this, the impact of communication and cognitive impairment on personal healthcare decision-making in MND is not well known.

AIMS

This exploratory, longitudinal study aimed to capture the perspectives of people living with MND (plwMND) and family members on managing their healthcare with, or in anticipation of, a communication impairment.

METHODS & PROCEDURES

Semi-structured interviews and functional assessments were conducted with plwMND and family members over one to three time points between December 2017 and January 2020. Participants were recruited from a specialist MND clinic using a maximum variation sampling approach. Interview transcripts were analysed using trajectory data analysis: a matrix-based approach for thematic analysis of longitudinal data. The study was underpinned by interpretive descriptive methodology.

OUTCOMES & RESULTS

A total of 19 plwMND with a range of MND phenotypes and 15 family members were recruited. Disease progression and participant withdrawal resulted in attrition, however 12 plwMND and seven family members participated at all three time points. Consistent cognitive screening was not feasible, which limited the opportunity to explore the impact of cognitive change. An overarching theme 'Communicating takes effort' was identified and illustrates the efforts required to compensate for, or circumnavigate, impairments to maintain involvement in healthcare. Assistance from family and accommodation from healthcare professionals (HCPs) was needed for ongoing engagement. Where plwMND were dependent on alternative communication devices, this assistance was essential and primarily carried out by family members. Despite these efforts, the quality, quantity and accuracy of communication were sometimes compromised. Participants equated good communication with receiving good healthcare, and some expressed anxiety in the anticipation of being unable to express their needs to healthcare workers.

CONCLUSION & IMPLICATIONS

Communication impairment has a direct impact on healthcare involvement. This study demonstrates the effort required by plwMND and their carers to maintain or maximize ongoing involvement. This effort may not always be visible to HCPs. This information may prompt clinicians to consider the best ways to conduct clinical consultations to accommodate patients' abilities. Compromised communication experiences can be moderated by accommodations and support from HCPs and appropriate adjustments in the health system. Asking patients about their communication preferences and needs, allowing extra time and conducting multidisciplinary sessions are examples of such support.

WHAT THIS PAPER ADDS

What is already known on this subject? Communication and cognitive impairments are known contributors to negative health outcomes and barriers to shared decision-making generally. The existing literature in decision-making in MND does not address the specific impact of these impairments on personal healthcare involvement for plwMND and their carers. What this paper adds to existing knowledge? This paper reports the findings of a research project that interviewed 19 plwMND and 15 carers on one to three occasions over a 26-month period to obtain their perspectives of the impact of communication on healthcare involvement. Whilst a priori the intention was to look at both communicative and cognitive decline, only the former was achieved. The effort and often 'invisible' activity undertaken to manage or maintain involvement in healthcare is identified. Communication impairment requires support and accommodation, otherwise healthcare involvement can be compromised. Results show participants may associate effective communication with good healthcare. What are the potential or actual clinical implications of the work? Clinicians may wish to use these insights from plwMND and their carers to guide adjustments to their professional practice to maximize healthcare involvement for their patients. Tailored education for different healthcare groups is needed to improve understanding of MND-related communication impairments and supportive strategies so that involvement in healthcare is not compromised.

Structural and functional brain connectome in motor neuron diseases: A multicenter MRI study

OBJECTIVE

To investigate structural and functional neural organization in amyotrophic lateral sclerosis (ALS), primary lateral sclerosis (PLS), and progressive muscular atrophy (PMA).

METHODS

A total of 173 patients with sporadic ALS, 38 patients with PLS, 28 patients with PMA, and 79 healthy controls were recruited from 3 Italian centers. Participants underwent clinical, neuropsychological, and brain MRI evaluations. Using graph analysis and connectomics, global and lobar topologic network properties and regional structural and functional brain connectivity were assessed. The association between structural and functional network organization and clinical and cognitive data was investigated.

RESULTS

Compared with healthy controls, patients with ALS and patients with PLS showed altered structural global network properties, as well as local topologic alterations and decreased structural connectivity in sensorimotor, basal ganglia, frontal, and parietal areas. Patients with PMA showed preserved global structure. Patient groups did not show significant alterations of functional network topologic properties relative to controls. Increased local functional connectivity was observed in patients with ALS in the precentral, middle, and superior frontal areas, and in patients with PLS in the sensorimotor, basal ganglia, and temporal networks. In patients with ALS and patients with PLS, structural connectivity alterations correlated with motor impairment, whereas functional connectivity disruption was closely related to executive dysfunction and behavioral disturbances.

CONCLUSIONS

This multicenter study showed widespread motor and extramotor network degeneration in ALS and PLS, suggesting that graph analysis and connectomics might represent a powerful approach to detect upper motor neuron degeneration, extramotor brain changes, and network reorganization associated with the disease. Network-based advanced MRI provides an objective in vivo assessment of motor neuron diseases, delivering potential prognostic markers.

Supporting access to activities to enhance well-being and reduce social isolation in people living with motor neurone disease

PURPOSE

People living with Motor Neurone Disease (plwMND) have emphasised the importance of psychological support and well-being in helping them manage their condition. Social prescribing is a formal process of referring patients with largely socioeconomic and psychosocial issues to a link worker to co-design a plan to improve their health and well-being. Intervention involves supporting engagement in meaningful activities based within the individual's local community. This pilot project aimed to explore the application of social prescribing with plwMND.

METHODS

A cohort of plwMND were supported by an occupational therapist and link worker to identify and access community-based activities. Qualitative interviews were completed post-intervention with the plwMND and the link workers. Findings were analysed using thematic analysis.

RESULTS

A total of nine plwMND took part in this pilot service, and five plwMND and four link workers were interviewed. PlwMND valued participation and wanted to engage in community-based activities. Those with mild symptomatology were able to access activities and reported a positive impact on their well-being. Those with more complex needs, particularly reduced mobility, experienced significant barriers to participation. Barriers included transport, equipment provision, lack of company to support participation and lack of confidence using mobility aids in a community environment. Link workers valued joint working with an occupational therapist.

CONCLUSION

Social prescribing aims to address the health inequalities of those living with long-term conditions, although currently it likely excludes plwMND. Future work needs to quantitatively evaluate the effects of the service on the well-being of plwMND.

Giving and receiving a diagnosis of a progressive neurological condition: A scoping review of doctors' and patients' perspectives

OBJECTIVE

Delivering a life changing diagnosis can be a distressing experience for patients and a challenging task for professionals. Diagnosis delivery can be especially difficult for individuals with neurodegenerative diseases such as motor neurone disease (MND), multiple sclerosis (MS) and Parkinson's disease (PD). This review aims to scope the literature on doctors' and patients' perspectives on diagnosis delivery for these conditions in order to enhance our understanding in this area and identify potential research gaps.

METHODS

A scoping review methodology was used, and data were summarised using content analysis.

RESULTS

47 studies fulfilled the inclusion criteria. Studies showed that although patients were generally satisfied with diagnosis delivery, a considerable proportion was still dissatisfied with aspects of the consultation, especially the information and time provided and the doctor's approach. Only six studies addressed doctors' perspectives, which focused more on doctors' practice.

CONCLUSION

There was a significant research gap in professionals' perspectives. The review also found that although basic standards of good practice were being met, a significant proportion of patients were dissatisfied with diagnosis communication.

PRACTICE IMPLICATIONS

Professionals delivering such diagnoses need to assess and respond to patients' information needs, provide time for questions and maintain an empathic attitude.

Living with motor neurone disease: an insider's sociological perspective

This article is a discussion between two former colleagues and longstanding friends about the lived experience of illness and disability. In January 2013, Kirsten Harley, a promising early career sociologist was diagnosed with motor neurone disease (MND), a degenerative neurological condition with a typical life expectancy of 2-3 years. In this article, which is part interview and part shared reflection, we consider how Kirsten's knowledge of sociology has shaped her responses to the illness. We 'discuss' the process of meaning making, health system navigation, interactions with health professionals, advocacy, becoming a 'passive activist', the role of technology and what we, as sociologists, might learn from a life so dramatically changed.

Gastrostomy uptake in motor neurone disease: a mixed-methods study of patients' decision making

OBJECTIVES

Gastrostomy decision making is a complicated, multifaceted process for people with motor neuron disease (MND). This study explored demographic and disease-related factors that may impact on gastrostomy uptake; and reasons why people with MND accepted or declined gastrostomy, with a focus on how perceptions of swallowing and nutrition may influence decision making.

DESIGN

Prospective, cross sectional, mixed methods.

SETTING

An Australian multidisciplinary, specialty MND Service.

PARTICIPANTS

33 patients were recommended gastrostomy by the treating medical specialist. 16 of 33 were invited to participate in the prospective decision making study; of whom 10 provided informed consent.

PRIMARY AND SECONDARY OUTCOME MEASURES

Demographic and disease-related factors contributing to uptake are described. A stepped approach was applied to gain a comprehensive understanding of why people with MND accept or decline gastrostomy. Instruments included standardised assessments, nutrition survey and semistructured interview. Data were collected at three separate appointments, spanning a 3-week period.

RESULTS

Gastrostomy uptake was 73% following medical specialist recommendation. Participants took days, weeks or months to consider their preferences, with lengthy hospital waiting times for the procedure. Gender, site of onset and rate of disease progression were observed to contribute to uptake. Age and symptom duration did not. Integration of quantitative and qualitative data suggests that patient perceptions of swallowing and nutrition contribute to gastrostomy acceptance; however, the decision making process is heterogeneous and these factors may not be the sole or primary reasons for acceptance. Other reported factors included: reducing carer burden, improving quality of life, increasing independence, continuing participation in social outings and gaining control.

CONCLUSIONS

Future research may give greater insight into how healthcare organisations can better facilitate gastrostomy decision making, to meet the needs of people living with MND. Larger, prospective, multisite studies may build on these findings to better inform clinical guidelines and minimise the impacts of delayed gastrostomy insertion.

Developing a web-based patient decision aid for gastrostomy in motor neuron disease: a study protocol

INTRODUCTION

Motor neuron disease (MND) is a progressive, incurable disease, characterised by degeneration of the nerves in the brain and spinal cord. Due to the multisystem effects of the disease, patients are faced with many complex, time-sensitive decisions, one of which is the decision on gastrostomy feeding. There are currently no published decision aids (DAs) to support patients making this decision in the UK. This study will develop and pilot a patient DA to provide evidence-based information on gastrostomy placement and feeding that is relevant to people with MND; communicate the risks and benefits associated with each option; check understanding and clarify personal values and preferences, enabling patients to make a decision congruent with their values and appropriate for them.

METHODS AND ANALYSIS

A two-phase process, observing the International Patient Decision Aid Standards, will be used to develop the DA, over 24 months starting January 2019. Phase 1 will use literature reviews and stakeholder interviews and surveys to identify essential content for the DA, and explore the best way to present this. In the second phase, a prototype DA will be developed and revised using stakeholder feedback in an iterative process. Stakeholders will include individuals with MND, their carers and the healthcare professionals working with them.

ETHICS AND DISSEMINATION

Ethical approval for the study has been granted by West of Scotland Research Ethics Service, reference 19/WS/0078. Study findings will be disseminated through academic and non-academic publications, conference presentations, stakeholder websites and social media. A feasibility study will follow to explore the acceptability and practicality of the DA for patients, carers and HCPs in practice and to assess whether the DA shows promise of being beneficial for the intended population.

A licence to drive? Neurological illness, loss and disruption

The sense of freedom and independence that being able to drive generates may be taken for granted by many until it is threatened by illness. Drawing on the 'mobility turn' in social sciences that emphasises the social and emotional significance of the car (Sheller and Urry , ), this article presents secondary analysis of narratives of driving and its significance across four neurological conditions (epilepsy, Parkinson's disease, transient ischaemic attack and motor neurone disease). Taking an interactionist approach we explore how the withdrawal of a driving licence can represent not just a practical and emotional loss of independence, but also loss of enjoyment; of a sense and feeling of 'normal' adulthood and social participation; and of an identity (in some cases gendered) of strength and power. Conversely the ability to keep driving can maintain an unbroken thread of narrative, for example enabling people with speech difficulties to feel and look normal behind the wheel. Moments of pleasure and normality illuminate the importance of examining the micro-strands of disruption illness can cause.

Prefrontal cortical thickness in motor neuron disease

Objective

To examine whether the distribution of prefrontal cortical thickness in patients with motor neuron disease is normal or bimodal and how it compares to the normal population.

Methods

158 patients with motor neuron disease (MND) and 86 healthy controls (HC) were enrolled in a prospective, two-center study with a common structural MRI protocol. Cortical thickness measures were extracted for the prefrontal cortex, premotor cortex, motor cortex, and occipital cortex using FreeSurfer, adjusted for age and sex, and tested for normality of distribution.

Results

Cortical thickness measures of the bilateral prefrontal, premotor, motor, and occipital cortex were normally distributed in patients and healthy controls. MND-related cortical thinning was observed in the right motor cortex (p = 0.002), reflected in a significantly higher proportion of MND cases being worse than −1 standard deviation of the healthy control mean: 29.1% in the right motor cortex (p = 0.002). Cortical thinning of the left motor cortex was a function of clinical phenotype and physical disability. Left prefrontal cortical thickness was reduced in patients with additional cognitive and/or behavioural deficits compared to MND patients without cognitive deficits. Prefrontal, premotor, motor, and occipital cortical thickness was related to patients' general cognitive abilities.

Conclusion

The study shows that prefrontal cortical thickness in MND is normally distributed but shifted towards thinner cortex in MND patients with cognitive and/or behavioural impairment. The distribution of thickness values did not indicate the assumption of a bimodal distribution although patients with comorbid cognitive deficits are more likely to suffer from prefrontal cortical thinning.

•

There is an increased prevalence of prefrontal cortical thinning in MND patients with cognitive and/or behavioural impairment.

•

Distribution of thickness values among different MND subgroups appear unimodal.

•

Thinning is dependent of clinical phenotype, disease severity, and cognitive impairment.

Cognitive and motor performance in Congolese children with konzo during 4 years of follow-up: a longitudinal analysis

BACKGROUND

Konzo is an irreversible upper-motor neuron disorder affecting children dependent on bitter cassava for food. The neurocognitive ability of children with konzo over time has yet to be fully documented.

METHODS

We did a longitudinal study in a konzo outbreak zone continuously affected by konzo since 1990, in the district of Kahemba, southern Bandundu Province, Congo. We enrolled children with a record of neurological diagnosis of konzo in Kahemba town. For all study children with konzo enrolled in the final sample for the baseline assessment, a neurological exam was done by neurologists to confirm konzo diagnosis using the 1996 WHO criteria at 2 years and 4 years. In the initial baseline sample for each child with konzo, we attempted to get consent from a comparison child without konzo (1996 WHO criteria) within 2 years of age, from a neighbouring household who met inclusion criteria. The neuropsychological assessments were the Kaufman Assessment Battery for Children, second edition (KABC-II), and the Bruininks-Oseretsky Test of Motor Proficiency, second edition (BOT-2).

FINDINGS

Data collection occurred between Oct 12, 2011, and Aug 14, 2015, in the town of Kahemba. 123 children from the Congo with konzo and 87 presumably healthy children without konzo from neighbouring households were enrolled. The planned assessments were completed by 76 children with konzo and 82 children without konzo at 2-year follow-up, and by 55 children with konzo and 33 children without konzo at 4-year follow-up. Boys with konzo did worse than those without konzo on the KABC-II Learning (p=0·0424) and on the Mental Processing Index (MPI; p=0·0111) assessments at 2-year follow-up, but girls did not. These differences observed in boys might have been caused by stunting. At 4-year follow-up, the difference in KABC-II MPI score between boys or girls with or without konzo was not significant. Both boys and girls with konzo had lower scores on BOT-2 than children without konzo at both follow-up times (p<0·0001). These differences were not attenuated when controlling for physical growth. Boys with and without konzo declined on BOT-2 fine motor proficiency at 2-year follow-up (boys with konzo p=0·0076; boys without konzo p=0·0224) and KABC-II MPI performance at 2-year follow-up and 4-year follow-up (2 years: boys with konzo p<0·0001, boys without konzo p=0·0213; 4 years: boys with konzo p=0·0256, boys without konzo p=0·10), but that was not the case for the girls with scores remaining stable regardless of konzo status. For boys, increases in urinary thiocyanate concentration was significantly associated with reductions in BOT-2 motor proficiency (p=0·0321), but was not significantly associated in girls and urinary thiocyanate concentration was not associated with KABC-II MPI score for either boys or girls.

INTERPRETATION

Motor and cognitive performance continues to be significantly impaired in boys with konzo at 2-year follow-up compared with boys without konzo. Because these impairments are associated in part with exposure to poorly processed cassava as measured by urinary thiocyanate, interventions are urgently needed to ensure improved processing of cassava to detoxify this food source.

Structural and functional brain signatures of C9orf72 in motor neuron disease

This study investigated structural and functional magnetic resonance imaging abnormalities in hexanucleotide repeat expansion in chromosome 9 open reading frame 72 (C9orf72) motor neuron disease (MND) relative to disease severity-matched sporadic MND cases. We enrolled 19 C9orf72 and 67 disease severity-matched sporadic MND patients, and 22 controls. Sporadic cases were grouped in patients with: no cognitive/behavioral deficits (sporadic-motor); same patterns of cognitive/behavioral impairment as C9orf72 cases (sporadic-cognitive); shorter disease duration versus other sporadic groups (sporadic-early). C9orf72 patients showed cerebellar and thalamic atrophy versus all sporadic cases. All MND patients showed motor, frontal, and temporoparietal cortical thinning and motor and extramotor white matter damage versus controls, independent of genotype and presence of cognitive impairment. Compared with sporadic-early, C9orf72 patients revealed an occipital cortical thinning. C9orf72 patients had enhanced visual network functional connectivity versus sporadic-motor and sporadic-early cases. Structural cerebellar and thalamic damage and posterior cortical alterations are the brain magnetic resonance imaging signatures of C9orf72 MND. Frontotemporal cortical and widespread white matter involvement are likely to be an effect of the disease evolution rather than a C9orf72 marker.

The frontotemporal dementia-motor neuron disease continuum

Early reports of cognitive and behavioural deficits in motor neuron disease might have been overlooked initially, but the concept of a frontotemporal dementia-motor neuron disease continuum has emerged during the past decade. Frontotemporal dementia-motor neuron disease is now recognised as an important dementia syndrome, which presents substantial challenges for diagnosis and management. Frontotemporal dementia, motor neuron disease, and frontotemporal dementia-motor neuron disease are characterised by overlapping patterns of TAR DNA binding protein (TDP-43) pathology, while the chromosome 9 open reading frame 72 (C9orf72) repeat expansion is common across the disease spectrum. Indeed, the C9orf72 repeat expansion provides important clues to disease pathogenesis and suggests potential therapeutic targets. Variable diagnostic criteria identify motor, cognitive, and behavioural deficits, but further refinement is needed to define the clinical syndromes encountered in frontotemporal dementia-motor neuron disease.

Development of patient decision support tools for motor neuron disease using stakeholder consultation: a study protocol

INTRODUCTION

Motor neuron disease (MND) is a terminal, progressive, multisystem disorder. Well-timed decisions are key to effective symptom management. To date, there are few published decision support tools, also known as decision aids, to guide patients in making ongoing choices for symptom management and quality of life. This protocol is to develop and validate decision support tools for patients and families to use in conjunction with health professionals in MND multidisciplinary care. The tools will inform patients and families of the benefits and risks of each option, as well as the consequences of accepting or declining treatment.

METHODS AND ANALYSIS

The study is being conducted from June 2015 to May 2016, using a modified Delphi process. A 2-stage, 7-step process will be used to develop the tools, based on existing literature and stakeholder feedback. The first stage will be to develop the decision support tools, while the second stage will be to validate both the tools and the process used to develop them. Participants will form expert panels, to provide feedback on which the development and validation of the tools will be based. Participants will be drawn from patients with MND, family carers and health professionals, support association workers, peak body representatives, and MND and patient decision-making researchers.

ETHICS AND DISSEMINATION

Ethical approval for the study has been granted by Macquarie University Human Research Ethics Committee (HREC), approval number 5201500658. Knowledge translation will be conducted via publications, seminar and conference presentations to patients and families, health professionals and researchers.

Motoneuron diseases: impact on health professionals

The approach to patients affected by motor neuron disease (MND) and their caregivers requires specific training for the care-team. In fact, the progression of the disease, with the decline of physical--and sometimes cognitive--function, the increasing difficulties in speaking, breathing, and swallowing and the need of invasive choices, as the artificial nutrition and tracheostomy, constitute a challenge for the health professionals, often generating distress. For this reason, their cohesion and sharing abilities are fundamental. Psychologist assumes a strategic role in supporting and facilitating the analysis of clinical cases and of the team's intra/interpersonal dynamics. For this aim, he/she needs specific training and instruments. We here present a semi-structured interview--the Motor Neuron Disease-Psychological Interview (MoNeDi-PI)--which may guide in the psychological assessment of patients affected by MNDs and their caregivers. It can also be a handy reference tool for other members of the healthcare team providing necessary information about the patient and caregiver in order to optimize clinical decision making about which health interventions to apply.

Unstable terminality: negotiating the meaning of chronicity and terminality in motor neurone disease

This paper explores the meaning of chronicity and terminality in motor neurone disease (MND), also known as amyotrophic lateral sclerosis (ALS). There is no known cause or cure for MND, and expected survival is 2-5 years, but several interventions may improve or prolong life. This study draws on qualitative interview data with health professionals in hospitals and primary care, and family carers, in Norway. The actors emphasised chronic and terminal aspects in subtly different ways along the entire illness trajectory, also when recounting the trajectory in retrospect. As a consequence of improved health services and medical technology the distinction between chronicity and terminality has become more vague and sometimes ambiguous. We suggest the concept unstable terminality to describe this ambiguity. While MND is a fatal diagnosis; it may be contested, as contingencies and interventions create an indefinite time scope. The instability creates challenges for primary care which is dependent on prognostic information to organise their effort; hospitals tackle the instability by pre-scheduled consultations allowing for avoidance of an explicit prognosis. Some carers experienced what we understand as a disruption within the disruption, living with chronic and terminal illness simultaneously, which made the limbo phase more challenging to overcome.

Dying with motor neurone disease, what can we learn from family caregivers?

BACKGROUND

Increasingly, people with neurodegenerative illness are cared for at home until close to death. Yet, discussing the reality of dying remains a social taboo.

OBJECTIVE

To examine the ways, family caregivers of people living with motor neurone disease (MND) experienced the dying of their relative and to identify how health practitioners can better prepare families for end-of-life care.

DESIGN

Secondary analysis was undertaken on data sets generated from two longitudinal qualitative studies employing similar data collection and analysis methods. Combining data sets increased participant numbers in a low incidence disease group.

SETTING AND PARTICIPANTS

Primary studies were undertaken with family caregivers in England and Australia. Interview and observational data were collected mostly in home. Participants who discussed dying and death formed the sample for secondary analysis.

RESULTS

Combined data revealed four major themes: planning for end of life, unexpected dying, dignity in the dying body and positive end to MND. Despite short survival predictions, discussions among family members about dying were often sporadic and linked to loss of hope. Effective planning for death assisted caregivers to manage the final degenerative processes of dying. When plans were not effectively communicated or enacted, capacity to preserve personhood was reduced.

DISCUSSION AND CONCLUSION

Returning death and dying to social discourse will raise the level of community awareness and normalize conversations about end-of-life care. Strategies for on-going, effective communication that facilitates advance care planning among patients, their families and practitioners are essential to improve dying and death for people with MND and their family caregivers.

Touching moments: phenomenological sociology and the haptic dimension in the lived experience of motor neurone disease

Currently, there is a relative research lacuna in phenomenological research into the lived experience of motor neurone disease. Based on a sociological research project in the UK, involving 42 participants diagnosed with MND, this article explores the potential of a phenomenological sociology for analysing experiences of this drastically life-limiting neurological disorder. Calls have been made for sociological researchers to analyse more fully and deeply the sensory dimension of the lived body, and this article also contributes to this newly developing body of literature. While the social sciences have been accused of a high degree of ocularcentrism, here we take forward the literature by specifically focusing upon the haptic dimension, given that touch - and particularly the loss of key elements of the haptic dimension- emerged as salient in MND patients' accounts. To illustrate the potential of our phenomenologically inspired theoretical perspective, we consider two specific haptic themes: (i) being out of touch: the loss of certain forms of touch within MND and (ii) unwelcome touch by medical staff.

Feasibility, acceptability, and potential effectiveness of dignity therapy for people with motor neurone disease

Background

Motor neurone disease (MND) practice guidelines suggest developing interventions that will promote hope, meaning, and dignity to alleviate psychological distress, but very little research has been done. This study begins to address this need by exploring the use of dignity therapy with people with MND. Dignity therapy is a brief psychotherapy that promotes hope, meaning and dignity, and enhances the end of life for people with advanced cancer. The aims of this study are to assess the feasibility, acceptability, and potential effectiveness of dignity therapy for people with MND.

Methods/design

This cross-sectional feasibility study used a one-group pre-test post-test design with 29 people diagnosed with MND. Study participants completed the following self-report questionnaires: Herth Hope Index, FACIT-sp, Patient Dignity Inventory, ALS Assessment Questionnaire, ALS Cognitive Behavioural Screen, and a demographic and health history questionnaire. Acceptability was measured with a 25-item feedback questionnaire. Feasibility was assessed by examining the length of time taken to complete dignity therapy and how symptoms common in MND affected the intervention. Generalised linear mixed models and reliable change scores were used to analyse the data.

Results

There were no significant pre-test post-test changes for hopefulness, spirituality or dignity on the group level, but there were changes in hopefulness on the individual level. The results of the feedback questionnaire indicates dignity therapy is highly acceptable to people with MND, who report benefits similar to those in the international randomised controlled trial on dignity therapy, a population who primarily had end-stage cancer. Benefits include better family relationships, improved sense of self and greater acceptance. Dignity therapy with people with MND is feasible if the therapist can overcome time and communication difficulties.

Conclusions

Dignity therapy for people with MND is feasible and acceptable. Further research is warranted to explore its ability to diminish distress.

Using joint interviews in a narrative-based study on illness experiences

Researchers are increasingly recognizing the usefulness of using joint interviews in research on illness experiences. However, there is limited discussion of joint interviews as a data collection method and of the factors that influence the choice to conduct individual or joint interviews. Although there are several advantages and disadvantages of both methods, the reasons that underpin the choice to use joint interviews are often not discussed in detail in the literature. Drawing from a narrative-based study on the experiences of living with motor neuron disease, we present joint interviews as a method sensitive both to the shared experience of illness and to the multiple perspectives around illness. Using interview excerpts, we discuss how through the use of joint interviews researchers can explore the intersubjective and heteroglossic nature of illness experiences. We argue that using joint interviews can offer valuable information about how couples coconstruct meaning and share experiences.

Resting state functional connectivity alterations in primary lateral sclerosis

Resting state functional connectivity of the sensorimotor and extramotor brain networks was studied in 24 patients with primary lateral sclerosis (PLS) relative to 26 healthy controls. The relationships of RS functional connectivity with patient clinical and cognitive status and white matter tract damage (i.e., corticospinal tracts, corpus callosum, and superior longitudinal fasciculus) were investigated. Compared with controls, PLS patients showed an increased functional connectivity within the sensorimotor, frontal, and left frontoparietal networks spanning the pre- and postcentral, medial and dorsal frontal, insular, and superior temporal regions. Patients with more severe physical disability and a more rapid rate of disease progression had increased sensorimotor connectivity values. The increased functional connectivity within the frontal network was associated with executive dysfunction. In addition, higher functional connectivity correlated with greater structural damage to network-specific white matter tracts. This study shows clinically meaningful increased resting state functional connectivity in PLS.

Assessing social isolation in motor neurone disease: a Rasch analysis of the MND Social Withdrawal Scale

OBJECTIVE

Social withdrawal is described as the condition in which an individual experiences a desire to make social contact, but is unable to satisfy that desire. It is an important issue for patients with motor neurone disease who are likely to experience severe physical impairment. This study aims to reassess the psychometric and scaling properties of the MND Social Withdrawal Scale (MND-SWS) domains and examine the feasibility of a summary scale, by applying scale data to the Rasch model.

METHODS

The MND Social Withdrawal Scale was administered to 298 patients with a diagnosis of MND, alongside the Hospital Anxiety and Depression Scale. The factor structure of the MND Social Withdrawal Scale was assessed using confirmatory factor analysis. Model fit, category threshold analysis, differential item functioning (DIF), dimensionality and local dependency were evaluated.

RESULTS

Factor analysis confirmed the suitability of the four-factor solution suggested by the original authors. Mokken scale analysis suggested the removal of item five. Rasch analysis removed a further three items; from the Community (one item) and Emotional (two items) withdrawal subscales. Following item reduction, each scale exhibited excellent fit to the Rasch model. A 14-item Summary scale was shown to fit the Rasch model after subtesting the items into three subtests corresponding to the Community, Family and Emotional subscales, indicating that items from these three subscales could be summed together to create a total measure for social withdrawal.

CONCLUSION

Removal of four items from the Social Withdrawal Scale led to a four factor solution with a 14-item hierarchical Summary scale that were all unidimensional, free for DIF and well fitted to the Rasch model. The scale is reliable and allows clinicians and researchers to measure social withdrawal in MND along a unidimensional construct.

Therapeutic exercise for people with amyotrophic lateral sclerosis or motor neuron disease

BACKGROUND

Despite the high incidence of muscle weakness in individuals with amyotrophic lateral sclerosis (ALS) or motor neuron disease (MND), the effects of exercise in this population are not well understood. This is an update of a review first published in 2008.

OBJECTIVES

To systematically review randomised and quasi-randomised studies of exercise for people with ALS or MND.

SEARCH METHODS

We searched The Cochrane Neuromuscular Disease Group Specialized Register (2 July 2012), CENTRAL (2012, Issue 6 in The Cochrane Library), MEDLINE (January 1966 to June 2012), EMBASE (January 1980 to June 2012), AMED (January 1985 to June 2012), CINAHL Plus (January 1938 to June 2012), LILACS (January 1982 to June 2012), Ovid HealthSTAR (January 1975 to December 2012). We also searched ProQuest Dissertations & Theses A&I (2007 to 2012), inspected the reference lists of all papers selected for review and contacted authors with expertise in the field.

SELECTION CRITERIA

We included randomised or quasi-randomised controlled trials of people with a diagnosis of definite, probable, probable with laboratory support, or possible ALS, as defined by the El Escorial criteria. We included progressive resistance or strengthening exercise, and endurance or aerobic exercise. The control condition was no exercise or standard rehabilitation management. Our primary outcome measure was improvement in functional ability, decrease in disability or reduction in rate of decline as measured by a validated outcome tool at three months. Our secondary outcome measures were improvement in psychological status or quality of life, decrease in fatigue, increase in, or reduction in rate of decline of muscle strength (strengthening or resistance studies), increase in, or reduction in rate of decline of aerobic endurance (aerobic or endurance studies) at three months and frequency of adverse effects. We did not exclude studies on the basis of measurement of outcomes.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted the data. We collected adverse event data from included trials. The review authors contacted the authors of the included studies to obtain information not available in the published articles.

MAIN RESULTS

We identified two randomised controlled trials that met our inclusion criteria, and we found no new trials when we updated the searches in 2012. The first, a study with overall unclear risk of bias, examined the effects of a twice-daily exercise program of moderate load endurance exercise versus "usual activities" in 25 people with ALS. The second, a study with overall low risk of bias, examined the effects of thrice weekly moderate load and moderate intensity resistance exercises compared to usual care (stretching exercises) in 27 people with ALS. After three months, when the results of the two trials were combined (43 participants), there was a significant mean improvement in the Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS) measure of function in favour of the exercise groups (mean difference 3.21, 95% confidence interval 0.46 to 5.96). No statistically significant differences in quality of life, fatigue or muscle strength were found. In both trials adverse effects, investigators reported no adverse effects such as increased muscle cramping, muscle soreness or fatigue

AUTHORS' CONCLUSIONS

The included studies were too small to determine to what extent strengthening exercises for people with ALS are beneficial, or whether exercise is harmful. There is a complete lack of randomised or quasi-randomised clinical trials examining aerobic exercise in this population. More research is needed.

Juvenile-onset motor neuron disease caused by novel mutations in β-hexosaminidase

A 12 year-old female presented with a seven-year history of progressive muscle weakness, atrophy, tremor and fasciculations. Cognition was normal. Rectal biopsy revealed intracellular storage material and biochemical testing indicated low hexosaminidase activity consistent with juvenile-onset G(M2)-gangliosidosis. Genetic evaluation revealed compound heterozygosity with two novel mutations in the hexosaminidase β-subunit (c.512-3 C>A and c.1613+15_1613+18dup). Protein analysis was consistent with biochemical findings and indicated only a small portion of β-subunits were properly processed. These results provide additional insight into juvenile-onset G(M2)-gangliosidoses and further expand the number of β-hexosaminidase mutations associated with motor neuron disease.

Rehabilitation of motor neuron disease

Amyotrophic lateral sclerosis (ALS), the most common adult motor neuron disease, is an acquired disorder that results in loss of function in multiple domains. Although there is no treatment that can halt or reverse this progressive condition, there are many opportunities for interventions that can lead to improved quality of life for the patient and caregiver. Physical and occupational therapy can assist with mobility and activities of daily living. Interventions by speech pathology can optimize nutrition and communication. Respiratory function can be managed noninvasively or invasively. Depression, hopelessness, anxiety, and other mental health issues can and should be aggressively addressed and treated. Many symptoms such as pseudobulbar affect, sialorrhea, constipation, spasticity, and cramps can be treated effectively with medications. Spirituality and religion are important issues to address, as are end-of-life concerns, including advance directives, hospice, and the dying process. In contrast to the discouraging view that "there is nothing we can do," a broad approach to management, through collaboration with a multidisciplinary team, will permit the ALS physician to make a meaningful difference in the lives of individuals living with ALS.

Terminal sedation: an emotional decision in end-of-life care

A patient with end-stage motor neurone disease was admitted for hospice care with worsening bulbar symptoms. Although he initially walked onto the ward he became very distressed and asked for sedation. After much discussion, this man was deeply sedated, and after some harrowing days, died. Was it right to provide terminal sedation? What should the threshold be for such treatment? How should our personal reservations affect how we approach the distressed patient in an end-of-life situation?

Unsolicited written narratives as a methodological genre in terminal illness: challenges and limitations

Stories about illness have proven invaluable in helping health professionals understand illness experiences. Such narratives have traditionally been solicited by researchers through interviews and the collection of personal writings, including diaries. These approaches are, however, researcher driven; the impetus for the creation of the story comes from the researcher and not the narrator. In recent years there has been exponential growth in illness narratives created by individuals, of their own volition, and made available for others to read in print or as Internet accounts. We sought to determine whether it was possible to identify such material for use as research data to explore the subject of living with the terminal illness amyotrophic lateral sclerosis/motor neuron disease--the contention being that these accounts are narrator driven and therefore focus on issues of greatest importance to the affected person. We encountered and sought to overcome a number of methodological and ethical challenges, which is our focus here.

Acquired dysarthria in conversation: methods of resolving understandability problems

BACKGROUND

People with acquired progressive dysarthria typically experience increased problems with intelligibility in everyday conversation as their disease progresses. Such problems are likely to impact on both the person with dysarthria and those with whom they interact. If this is the case then we may ask questions not just about the nature of these problems but how it is that such problems are dealt with by participants when they occur.

AIMS

To investigate ways through which problems resulting from dysarthria in everyday conversation are resolved by participants. Further, to examine some of the features of repair resolution, particularly where understanding of self-repair attempts themselves prove difficult.

METHODS & PROCEDURES

Video data of natural conversation from two dyads were selected for this paper. One dyad features a 58 year-old man with multiple sclerosis and moderate intelligibility problems, the other a 79 year-old woman with motor neurone disease with mild to moderate intelligibility problems. Both elected to be recorded in conversation with their spouses. The dyads were video-recorded at home with no researcher present. Using the methods of Conversation Analysis (CA) a collection of sequences was identified and transcribed. The sequences were analysed with reference to how the participants resolve problems in the understanding of dysarthric speech.

OUTCOMES & RESULTS

It is shown how some problems resulting from dysarthria in conversation can be resolved relatively quickly, particularly where a specific element of a prior turn is highlighted by the recipient as problematic. In other instances, the recipient's understanding problem may be more global. These result in longer repair sequences in which problematic elements are addressed individually. Such a resolution method is ultimately successful but may also be characterised by additional understanding problems. These findings draw attention to an important distinction between intelligibility and understandability.

CONCLUSIONS & IMPLICATIONS

It is concluded that problems resulting from dysarthria in conversation can require extensive repair work involving both parties. This has implications for the assessment of dysarthria in everyday conversation and also the promotion of intervention strategies that encompass the activities of both participants when dealing with dysarthria in interaction. These findings may be usefully employed in informing both direct clinical work and through training those who work with this client group and their significant others.

Neuropsychological functioning in PLS: a comparison with ALS

OBJECTIVE

In order to characterize the nature and extent of neuropsychological dysfunction in primary lateral sclerosis (PLS), we studied prospectively cognitive, emotional, and behavioral functioning in PLS, and compared performances to functioning in amyotrophic lateral sclerosis (ALS).

METHODS

Eighteen patients with PLS and 13 patients with ALS completed a neuropsychological test battery assessing both cognitive skills and emotional/behavioral functioning.

RESULTS

Both PLS and ALS groups scored broadly within normal limits (mean T-scores greater than 40) on all cognitive measures and no significant between-group differences were found with the exception of one variable. However, when examined on a case by case basis, the data revealed considerable heterogeneity amongst patients in both groups. Overall, 39% of PLS patients and 31% of ALS patients were considered cognitively impaired. Ahigher than expected frequency of abnormal scores was noted for several tests of executive function in both groups, and a majority of PLS patients also exhibited abnormal behavioural symptoms. There was no relationship in PLS or ALS groups between cognitive functioning and disease duration, current site of disease, site of onset, functional status, and respiratory variables. Comparison between the PLS and ALS groups indicated virtually no differences in cognitive test scores and overall emotional/behavioural symptoms.

CONCLUSIONS

We observed deficits in cognition and behaviour in a significant proportion of PLS patients which were comparable to those observed in ALS cases. Although deficits were not in the range of frontotemporal dementia, both ALS and PLS cases demonstrated deficits most prominently on tests of executive functioning.

Discussing sexuality with patients in a motor neurone disease clinic

Sexual relationships remain an important aspect of life for people living with motor neurone disease. This article explores the use of the Extended-PLISSIT model when discussing relationships and sexual function with patients and their partners in a motor neurone disease clinic. The model provides a structured approach to assist discussions with patients as well as promoting reflection and exchange of knowledge in the multidisciplinary team. It is a useful model when addressing issues that are sometimes difficult to discuss.

'Daddy is going to be sick'. Interview by Catherine Quinn

Motor neurone disease is a devastating diagnosis at any age, but for people with young children there is an added dimension. Now there is accessible information that can help.

Biographical disruption, abruption and repair in the context of motor neurone disease

Concepts of biographical disruption and repair have been widely applied to chronic illness, but not terminal illness. This paper examines the relevance of these concepts to motor neurone disease (MND), a progressive neurological condition characterised by loss of mobility, speech and ability to breathe or swallow. Survival is usually between two and five years, and some die within a few months. The condition thus lies at the boundary between chronic and terminal illness. Narrative interviews were conducted with 35 people living with MND and 11 family carers; analysis explored how people constructed their accounts as well as what they said. As well as accounts of biographical disruption, we identified a distinctive sense that the diagnosis is a 'death sentence' and life is already over, which we term 'biographical abruption'. We also found instances of biographical repair, as participants sought to make sense of their remaining life, restore normality and control, and find new meaning and identity.

[Survey of cognitive function in motor neuron disease]

OBJECTIVE

The aim of the study is to investigate the prevalence of cognitive impairment 100 and frontotemporal dysfunction in Chinese patients with motor neuron disease (MND).

METHODS

patients diagnosed as MND underwent a series of survey including mini mental state examination (MMSE), neuropsychiatry inventory (NPI), Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA).Demographics, site of onset, and disease severity-functional rating scale (FRS) were also investigated.

RESULTS

The prevalence of mild cognitive impairment determined with MMSE score was 24.2%. Comparison between patients with normal and abnormal MMSE showed statistic differences in depression state and FRS score. Since patients with anxiety and depression would also have abnormal NPI, a follow up study after 3-month antidepressive therapy for the depression patients was made and 2 patients were found to have probably frontotemporal dysfunction lasting for more than 6 months.

CONCLUSION

MND patients might have mild impairment of cognitive function and some of the patients were neuroethologically abnormal. 2 of the patients might have frontotemporal dysfunction.

The impact of neurological illness on marital relationships

The current study investigated the impact of neurological illness on marital relationship satisfaction. Participants numbered 423 patients and 335 carers from motor neurone disease (MND), Huntington's disease (HD), Parkinson's, and multiple sclerosis (MS). The results demonstrated that patients and carers with HD had a significantly lower level of relationship satisfaction and sex life satisfaction than the other three illness groups. Further, patients with HD indicated a significantly higher level of relationship satisfaction than their carers. For MS and MND patients, social support predicted marital relationship satisfaction, and for Parkinson's patients, social support and sex life satisfaction predicted marital relationship satisfaction.

Caregiver bodywork: family members' experiences of caring for a person with motor neurone disease

AIM

This paper reports a study of how family members caring for people living with motor neurone disease managed the deteriorating body, their own bodywork and the associated emotional labour.

BACKGROUND

People living with the neurodegenerative condition of motor neurone disease face the prospect of dying in 3-5 years from progressive loss of voluntary muscle mass and function, culminating in respiratory failure. Theories concerning the body in illness have been used to illustrate patient perspectives; however, family caregivers' experiences of the body have been neglected.

METHOD

An ethnographic case study was undertaken with 18 primary family caregivers and six peripheral caregivers. Primary caregivers participated over 10 months in three face-to-face, semi-structured interviews which included mapping their support networks using ecomaps. Observational data were also recorded as field notes. Peripheral caregivers were interviewed once during the same time period. The data were generated between 2003 and 2004.

FINDINGS

Informal caregiving requires engagement in various aspects of bodywork. Three body concepts were identified: the visible body--how the disease affected the patient and caregivers; the dependent body--the resulting care requirements; and the social body--how living with motor neurone disease affected their social support networks. The visible body is a continual reminder of the ravages of the disease, while the dependent body demands physical and emotional care. Social interactions decline over time, depriving family caregivers of the much needed support for sustaining their commitment to the bodywork required in caregiving.

CONCLUSION

The demands of bodywork for family caregivers are increased by the continual presence of emotional labour as they seek to implement the best way to support their relative with motor neurone disease. Nurses and allied healthcare workers need to assess each family situation, asking appropriate questions to establish the most appropriate interventions to facilitate supportive care.

Fatigue and activity dependent changes in axonal excitability in amyotrophic lateral sclerosis

BACKGROUND

While patients with amyotrophic lateral sclerosis (ALS) may complain of fatigue, the underlying mechanisms appear complex, with dysfunction of central and peripheral nervous systems independently reported as contributing factors. The aim of the present study was to further delineate the mechanisms underlying increased fatigability in ALS by measuring activity dependent changes in axonal excitability following a maximum voluntary contraction (MVC).

METHODS

Nerve excitability changes were recorded before and after an MVC of the abductor pollicis brevis in 16 patients with ALS and 25 controls.

RESULTS

In patients with ALS, there was a greater increase in threshold (36.5 (5.9)%; controls 19.6 (3.5)%; p<0.05) as a result of MVC, with reduction in the amplitude of the compound muscle action potential generated by a submaximal stimulus (ALS 49 (7.6)%; controls 41.0 (5.4)%). These changes were associated with an increase in superexcitability (ALS 65.1 (25.4)%; controls 42.3 (5.7)%) and reduction in strength-duration time constant (ALS 20 (4.9)%; controls 10 (2.5)%; p<0.01), indicative of axonal hyperpolarisation. The increase in threshold was more pronounced in patients with ALS with predominantly lower motor neuronal involvement.

CONCLUSIONS

Higher firing rates of surviving motor axons attempting to compensate for neurogenic weakness are likely to explain the greater activity dependent changes in ALS. As such, the present study suggests a further peripheral factor underlying the development of fatigue in ALS.
