Anxiety undermines quality of life in ALS patients and caregivers

Living beyond loss: a qualitative investigation of caregivers' experiences after the death of their relatives with amyotrophic lateral sclerosis

BACKGROUND

Caregivers of Amyotrophic Lateral Sclerosis (ALS) patients experience varying psychological responses following the patient's death, including sadness, loneliness, guilt, and a loss of purpose.

OBJECTIVES

This research aims to investigate the caregiver journey experienced from the time of diagnosis to the loss of a care recipient, with a specific focus on understanding the factors that contribute to improved coping with bereavement.

METHODS

The present study used the Interpretative Phenomenological Approach (IPA) to qualitatively explore the accounts of 41 Italian bereaved caregivers of people affected by ALS (Mean Age = 59.78; Female: 60.98%; Male: 39.02%).

RESULTS

Results revealed 5 overarching themes representing 5 macro areas that emerged from the analysis of the interviews ("Caregiver's perception of his/her life", "Caregiver's feelings", "Caregiver's life after patient's death", "Caregiver's disease description", "Caregiver's help resources"), these were further defined based on 12 main themes, which were, in turn, articulated into 30 subthemes. The transition from life before ALS ("a peaceful landscape") to caregiver life (compared to the color "black") was a "shock", during which caregivers had to change their needs. However, life after the person living with ALS' death was both characterized by a sense of "re-birth" and "emptiness", and a general need for "psychological assistance" and "social support".

CONCLUSIONS

Results emphasize the need to improve the psychological support offered to caregivers of person living with ALS after the patient's death, tailoring it to the specificity of the condition, to meet their emotional needs, reduce isolation and help them cope with practical challenges and plans.

Symptoms of anxiety and depression in patients with amyotrophic lateral sclerosis and their relatives during the disease trajectory

OBJECTS

The aim of this study was to describe the presence of anxiety and depression among patients with Amyotrophic Lateral Sclerosis (ALS) and their relatives from diagnosis and during the disease progression. An additional aim was to explore if the patient's physical function correlated with the patients' or relatives' anxiety and depression.

METHODS

A prospective and longitudinal study, including 33 patients with ALS and their relatives who filled out the Hospital Anxiety and Depression Scale (HADS) at the time of diagnosis and over a period of two years. The patient's physical function was measured with the revised Amyotrophic Lateral Sclerosis Functional and Rating Scale (ALS FRS-R).

RESULTS

The results showed that many patients (45%) and relatives (58%) had symptoms of anxiety and that 13% of the patients and 29% of the relatives had symptoms of depression soon after the patient had been diagnosed with ALS. The prevalence of anxiety decreased over time in the group of patients but remained stable in the group of relatives. Relatives had more symptoms of anxiety compared to patients. There was a correlation between the patient's physical function and HADS in the group of relatives; however, no correlation was found in the group of patients.

CONCLUSION

The results showed that many patients and relatives suffered from symptoms of anxiety quite soon after their diagnosis, and that many relatives had symptoms of anxiety during the disease trajectory. This highlights the need to continuously measure patients' anxiety/depression level but also to pay attention to symptoms among relatives.

A Palliative Care Approach to Amyotrophic Lateral Sclerosis

INTRODUCTION

Amyotrophic lateral sclerosis (ALS) is a degenerative disease characterized by motor dysfunction. Currently, treatment options are limited and management is based mostly on symptom control and quality of life optimization, so palliative care plays a fundamental role. Our objective was to characterize the ALS population in Madeira Island that was referenced and/or followed by a palliative care unit over a five-year period.

METHODS

Longitudinal, retrospective, descriptive, and observational study to analyze patients with ALS who were referred and/or followed by a palliative care unit during a five-year period, between 2017 and 2021. Patient's medical electronic and physical records were analyzed to gather data. Descriptive and inferential statistical analysis was done using Microsoft Excel and Statistical Package for the Social Sciences (version 28.0.1).

RESULTS

During this five-year period, a total of 38 patients were diagnosed with ALS in Madeira Island and 23 (60.53%) were referred to palliative care. Three patients died before assessment, so 20 (50.63%) were followed by the palliative care team. They had a median life expectancy of 425 days and the median time spent in palliative care was 137 days. Of this population, 56.52% (n=13) was male with an average age of 64 years. The median period from diagnosis to referral was 167 days, with most referrals being made by family medicine (39.13%; n=9) motivated by uncontrolled symptoms (95.65%; n=22). The median period from referral to first assessment by a palliative care physician was 19 days. The Palliative Performance Scale (PPS) and Confusion Assessment Method (CAM) applied on the first visit had a median score of 40% in the former and was negative in 95.00% (n=19) of patients in the latter. Advanced care directives were present in 55.00% (n=11) of patients and all provided care was in accordance with the patient's wishes. The most common symptoms were dysphagia, dyspnea, pain, anxiety, and sialorrhea. The most used drugs were morphine, riluzole, butylscopolamine, bisacodyl, and midazolam. As for other interventions, 55.00% (n=11) of patients underwent noninvasive ventilation (NIV), 15.00% (n=3) were submitted to percutaneous endoscopic gastrostomy (PEG), and one patient (5.00%) was nasogastrically intubated. The death rate was 95.00% (n=19) with 73.68% (n=14) of deaths occurring in the palliative care unit.

CONCLUSION

Literature has shown that there are many advantages to the early inclusion of palliative care in ALS management, achieving effective symptom control and greater quality of life, but also reducing caregiver burden. However, in this study, we found that referrals to palliative care were late and included mostly cases of advanced disease with uncontrolled symptoms.

When perfectionists adopt health behaviors: perfectionism and self-efficacy as determinants of health behavior, anxiety and depression

Background

The study aims to show interrelations between self-efficacy, perfectionism (adaptive and maladaptive), health behavior, and mental health outcomes such as anxiety and depression as an exponent in maintaining optimal health. In the analyses, we focused on one category of health behaviors – preventive practices.

Participants and procedure

Of the gathered data, 295 complete datasets were analyzed (age: M = 28.16, SD = 9.41; 72.8% participants female). We pro-posed two path models with personality traits (as exogenous variables) and health behaviors (as endogenous variables) in predicting depression and anxiety.

Results

Multiple regression analysis revealed that maladaptive perfectionism and generalized self-efficacy significantly predicted health behaviors in general and mental health outcomes whereas adaptive perfectionism and generalized self-efficacy were significant predictors of preventive practices. The path analyses showed that generalized self-efficacy and perfectionism are related directly to mental health outcomes as well as indirectly, through health behaviors. Interestingly, we found a negative indirect effect of an interaction between generalized self-efficacy and preventive practices as well as of an interac-tion between adaptive perfectionism and preventive practices on mental health outcomes. The model fitted well with the data.

Conclusions

The findings show that a balanced and more holistic approach to maintaining health is beneficial for people high in self-efficacy in comparison with high focus on disease prevention. Additionally, the results demonstrate that adaptive perfec-tionists and people high in self-efficacy may also be prone to anxiety and depression (not just maladaptive perfectionists) when their health focus is too narrow.

Alteration of interoceptive sensitivity: expanding the spectrum of behavioural disorders in amyotrophic lateral sclerosis

Background

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder with progressive loss of upper and lower motor neurons. Non-motor-symptoms, such as cognitive, emotional, autonomic, and somatosensory alterations, have been also described.

Interoception represents the link between the body and brain, since it refers to the ability to consciously perceive the physical condition of the inner body, including one’s heartbeat (i.e., interoceptive sensitivity, IS).

Objectives

To evaluate IS in ALS patients by means of a well-established task: the heartbeat perception task. Moreover, we evaluated possible correlations between IS and neuropsychological, affective, and disease-related characteristics.

Methods

Fifty-five ALS patients (mean-age = 60.3 ± 12.5 years; mean disease-duration = 20.9 ± 18.8 months) and 41 caregivers (CG) underwent the heartbeat perception task and an extensive evaluation of motor, cognitive, body awareness, affective, and emotion domains.

Results

ALS patients showed lower IS than CG (0.68 ± 0.24 vs 0.82 ± 0.16; p = 0.003). Significant correlations were found between IS and self-reported measures of alexithymia (subscale of Toronto Alexithymia scale-20 “difficulties in describing feelings”; rho =  − .391, p = .003) and interoceptive awareness (subscale of Multidimensional assessment of interoceptive awareness “not worrying about pain”; rho = .405, p = .002). No significant differences were found on questionnaires for depression and anxiety between patients with ALS and their caregivers (p > .05).

Conclusions

ALS patients show reduced interoceptive sensitivity that is associated with poorer ability to describe feelings and with lower focalization on pain, regardless of cognitive and motor impairment. Alteration of interoception may represent a specific behavioural sign within the spectrum of emotion processing deficits described in ALS patients.

Pain-Related Factors and Their Impact on Quality of Life in Chinese Patients With Amyotrophic Lateral Sclerosis

Objectives

Pain is considered a common symptom in amyotrophic lateral sclerosis (ALS). However, the results of studies on pain in ALS are limited and inconsistent. The aim of our study was to comprehensively evaluate the potential factors of pain and effects on quality of life (QoL) in patients with ALS from China.

Participants and Methods

Patients were eligible if they fulfilled the criteria of probable and definitive ALS according to the revised El Escorial criteria. Pain was assessed by the Brief Pain Inventory (BPI). Disease severity, sleep quality, fatigue, anxiety, depression, and quality of life (QoL) were evaluated in ALS patients by the ALS Functional Rating Scale-revised (ALSFRS-R) and ALS severity scale (ALSSS), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), Hamilton Anxiety Rating Scale (HARS), Hamilton Depression Rating Scale (HDRS) and McGill Quality of Life Questionnaire (MQOL). Then, the clinical characteristics of ALS patients with pain were compared with those without pain. Last, associated factors of pain, as well as impact on QoL in Chinese ALS patients, were assessed.

Results

A total of 86 ALS patients were included. ALS patients with pain tended to have higher FSS scores and poorer QoL. The FSS score and ALSSS [lower extremity (LE) + upper extremity (UE)] were associated with pain in ALS patients. The ALS Functional Rating Scale-revised (ALSFRS-R), Pain Severity Index (PSI), HARS and HDRS scores were significantly associated with both the physical and psychological domains of QoL.

Conclusion

Our study was the first to comprehensively evaluate factors associated with pain in Chinese ALS patients, finding that fatigue can be a risk factor for pain and ALSSS (LE + UE) score was related with pain intensity. Additionally, we identified the adverse effects of ALSSS (LE + UE), HARS and HDRS scores on QoL in Chinese ALS patients.

Home-Based Music Therapy to Support Bulbar and Respiratory Functions of Persons with Early and Mid-Stage Amyotrophic Lateral Sclerosis-Protocol and Results from a Feasibility Study

Respiratory failure, malnutrition, aspiration pneumonia, and dehydration are the precursors to mortality in ALS. Loss of natural communication is considered one of the worst aspects of ALS. This first study to test the feasibility of a music therapy protocol for bulbar and respiratory rehabilitation in ALS employs a mixed-methods case study series design with repeated measures. Newly diagnosed patients meeting the inclusion criteria were invited to participate, until the desired sample size (n = 8) was achieved. The protocol was delivered to participants in their homes twice weekly for six weeks. Individualised exercise sets for independent practice were provided. Feasibility data (recruitment, retention, adherence, tolerability, self-motivation and personal impressions) were collected. Bulbar and respiratory changes were objectively measured. Results. A high recruitment rate (100%), a high retention rate (87.5%) and high mean adherence to treatment (95.4%) provide evidence for the feasibility of the study protocol. The treatment was well tolerated. Mean adherence to the suggested independent exercise routine was 53%. The outcome measurements to evaluate the therapy-induced change in bulbar and respiratory functions were defined. Findings suggest that the protocol is safe to use in early- and mid-stage ALS and that music therapy was beneficial for the participants' bulbar and respiratory functions. Mean trends suggesting that these functions were sustained or improved during the treatment period were observed for most outcome parameters: Maximal Inspiratory Pressure, Maximal Expiratory Pressure, Peak Expiratory Flow, the Center for Neurologic Study-Bulbar Function Scale speech and swallowing subscales, Maximum Phonation Time, Maximum Repetition Rate-Alternating, Maximum Repetition Rate-Sequential, Jitter, Shimmer, NHR, Speaking rate, Speech-pause ratio, Pause frequency, hypernasality level, Time-to-Laryngeal Vestibule Closure, Maximum Pharyngeal Constriction Area, Peak Position of the Hyoid Bone, Total Pharyngeal Residue C24area. Conclusion. The suggested design and protocol are feasible for a larger study, with some modifications, including aerodynamic measure of nasalance, abbreviated voice sampling and psychological screening.

Fatigue in Chinese Patients With Amyotrophic Lateral Sclerosis: Associated Factors and Impact on Quality of Life

Objectives

Fatigue was considered as a common symptom in amyotrophic lateral sclerosis (ALS). Previous studies about the impact of fatigue on Quality of Life (QoL) in patients with ALS were limited and inconsistent. Besides, a systematic investigation of fatigue in Chinese patients with ALS was lacking. Therefore, this study aimed to comprehensively evaluate the frequency and associated factors of fatigue and impact on QoL in Chinese patients with ALS.

Participants and Methods

Probable and definitive patients with ALS and age- and gender-matched healthy controls (HCs) were consecutively recruited. The frequency of fatigue between both the groups was determined by the Fatigue Severity Scale (FSS). Disease severity, sleep quality, sleepiness, anxiety, depression, and QoL were evaluated in patients with ALS by the ALS Functional Rating Scale-revised (ALSFRS-R) and the ALS Severity Scale (ALSSS), the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Hamilton Anxiety Rating Scale (HARS), the Hamilton Depression Rating Scale (HDRS), and the McGill Quality of Life Questionnaire (MQOL). Then, clinical characteristics of patients with ALS with fatigue were compared with those without fatigue. Lastly, associated factors of fatigue and impact on QoL in Chinese patients with ALS were assessed.

Results

A total of 175 patients with ALS and 175 HCs were included. Fatigue was significantly more frequent in patients with ALS than in controls (32.6 vs. 17.7%, p = 0.001). Patients with ALS with fatigue scored lower on the ALSFRS-R, the ALSSS [lower extremity (LE) + upper extremity (UE)], the total ALSSS, higher in the HARS, HDRS, PSQI, ESS scores, and a poorer QoL. Daytime dysfunction and the ALSSS (LE + UE) score were associated with a higher risk of fatigue. The ALSSS (LE + UE), the FSS, age, the HARS, and the HDRS score were significantly associated with various aspects of QoL.

Conclusion

This study has described fatigue in Chinese patients with ALS and finding daytime dysfunction and the lower ALSSS (LE + UE) were associated with a higher risk of fatigue. Also, we identified an inverse relationship of fatigue intensity with the psychological domain of QoL.

Thick Mucus in ALS: A Mixed-Method Study on Associated Factors and Its Impact on Quality of Life of Patients and Caregivers

In this explorative mixed-method pilot study, we set out to have a closer look at the largely under-recognized and under-investigated symptom of thick mucus in patients with ALS and its impact on patients and relatives. Thick mucus is a highly distressing symptom for both patients and caregivers. It complicates the use of non-invasive ventilation and is therefore an important prognostic factor of survival. Methods: In our preliminary study, we used a cross-sectional design, including ten ALS patients with thick mucus who were matched to ten ALS patients without thick mucus. Lung function tests and laboratory and sputum analysis were performed and questionnaires administered in order to determine associated factors of thick mucus accumulation. In a qualitative study using semi-structured interviews, we analysed the impact of thick mucus on patients and caregivers. Results: Reduced respiratory parameters as well as a higher degree of bulbar impairment were associated with the presence of thick mucus. Quality of life of patients and caregivers was strongly impaired by thick mucus accumulation. Conclusions: Thick mucus in patients with ALS has a strong impact on quality of life. Reduced cough flow and severely impaired bulbar function appear to be indicative parameters. We suggest that healthcare providers actively explore the presence of thick mucus in their patients and that it becomes included in commonly used screening tools.

Quality of life and mental health in the locked-in-state-differences between patients with amyotrophic lateral sclerosis and their next of kin

For both patients with amyotrophic lateral sclerosis (ALS) and their next of kin (NOK), the maintenance of quality of life (QoL) and mental health is particularly important. First studies suggest significant discrepancies between QoL reports by patients and NOK, but little is known for advanced ALS stages. To address this issue, we screened 52 ALS patients in incomplete locked-in state (iLIS). Final results were obtained for 15 couples of iLIS patients and NOK. We assessed patients’ and NOK’s subjective QoL, depression and anxiety and NOK’s caregiver burden. Gaze controlled questionnaires allowed direct assessment of patients. Patients and NOK self-reported comparable, mostly moderate to high levels of QoL. Of note, NOK indicated stronger anxiety symptoms. Higher anxiety levels in NOK were associated with stronger caregiver burden and reduced QoL. No significant misjudgment of patient’s QoL by the NOK was evident, while patients overestimated NOK’s global QoL. However, NOK with severe caregiver burden and depression symptoms gave poorer estimations of patients’ QoL. This relationship is relevant, considering NOK’s impact on life critical treatment decisions. While the daily time NOK and patient spend together was positively correlated with NOK’s QoL and mental health, this was not reversely found for the patients. Our results suggest that NOK adapt less successfully to the disease and concomitant experience of loss and point to an urgent need for specialized psychosocial support. The findings emphasize the importance of direct psychological wellbeing assessment of both patients and NOK in clinical practice, enabled by eye-tracking technology for patients in iLIS.

Developments in the assessment of non-motor disease progression in amyotrophic lateral sclerosis

INTRODUCTION

The burden of non-motor symptoms is a major determinant of quality of life and outcome in amyotrophic lateral sclerosis (ALS) and has profound negative effect also on caregivers.

AREAS COVERED

Non-motor symptoms in ALS include cognitive impairment, neurobehavioral symptoms, depression and anxiety, suicidal ideation, pain, disordered sleep, fatigue, weight loss and reduced appetite, and autonomic dysfunctions. This review summarizes the measures used for the assessment of non-motor symptoms and their properties and recaps the frequency and progression of these symptoms along the course of ALS.

EXPERT OPINION

Non-motor symptoms in ALS represent a major component of the disease and span over several domains. These symptoms require a high level of medical attention and should be checked at each visit using ad hoc questionnaires and proactively treated. Several instruments assessing non-motor symptoms have been used in ALS. Specific screening questionnaires for non-motor symptoms can be used for monitoring patients during telehealth visits and for remote surveillance through sensors and apps installed on smartphones. Novel trials for non-motor symptoms treatment specifically designed for ALS are necessary to increase and refine the therapeutic armamentarium. Finally, scales assessing the most frequent and burdensome non-motor symptoms should be included in clinical trials.

Informal Caregiving in Amyotrophic Lateral Sclerosis (ALS): A High Caregiver Burden and Drastic Consequences on Caregivers' Lives

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that causes progressive autonomy loss and need for care. This does not only affect patients themselves, but also the patients’ informal caregivers (CGs) in their health, personal and professional lives. The big efforts of this multi-center study were not only to evaluate the caregivers’ burden and to identify its predictors, but it also should provide a specific understanding of the needs of ALS patients’ CGs and fill the gap of knowledge on their personal and work lives. Using standardized questionnaires, primary data from patients and their main informal CGs (n = 249) were collected. Patients’ functional status and disease severity were evaluated using the Barthel Index, the revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) and the King’s Stages for ALS. The caregivers’ burden was recorded by the Zarit Burden Interview (ZBI). Comorbid anxiety and depression of caregivers were assessed by the Hospital Anxiety and Depression Scale. Additionally, the EuroQol Five Dimension Five Level Scale evaluated their health-related quality of life. The caregivers’ burden was high (mean ZBI = 26/88, 0 = no burden, ≥24 = highly burdened) and correlated with patients’ functional status (r_p = −0.555, p < 0.001, n = 242). It was influenced by the CGs’ own mental health issues due to caregiving (+11.36, 95% CI [6.84; 15.87], p < 0.001), patients’ wheelchair dependency (+9.30, 95% CI [5.94; 12.66], p < 0.001) and was interrelated with the CGs’ depression (r_p = 0.627, p < 0.001, n = 234), anxiety (r_p = 0.550, p < 0.001, n = 234), and poorer physical condition (r_p = −0.362, p < 0.001, n = 237). Moreover, female CGs showed symptoms of anxiety more often, which also correlated with the patients’ impairment in daily routine (r_s = −0.280, p < 0.001, n = 169). As increasing disease severity, along with decreasing autonomy, was the main predictor of caregiver burden and showed to create relevant (negative) implications on CGs’ lives, patient care and supportive therapies should address this issue. Moreover, in order to preserve the mental and physical health of the CGs, new concepts of care have to focus on both, on not only patients but also their CGs and gender-associated specific issues. As caregiving in ALS also significantly influences the socioeconomic status by restrictions in CGs’ work lives and income, and the main reported needs being lack of psychological support and a high bureaucracy, the situation of CGs needs more attention. Apart from their own multi-disciplinary medical and psychological care, more support in care and patient management issues is required.

Prevalence of depression among amyotrophic lateral sclerosis (ALS) patients: A systematic review and meta-analysis

BACKGROUND

Amyotrophic lateral sclerosis (ALS) people have a high risk of severe mental disorders, like depression, which impacts their function, quality of life, and mobility. However, there are no estimates of depression based paper published. This study aimed conduct a systematic review and meta-analysis of the prevalence of depression in ALS patients around the world.

METHODS

PubMed/Medline, Web of science, Scopus, Embase, and Ovid are searched to identify papers that reporting the prevalence of depression. Studies are included in random-effects meta-analyses of the prevalence of depression. Subgroup analyses are performed on the severity of depression, instruments of depression, type of studies, and study regions.

RESULTS

46 eligible studies reported prevalence of depression. The pooled prevalence of depression among ALS people was 34% (27%-41%). According to the severity of depression, mild, moderate, and severe depression were 29%, 16%, and 8%, respectively. For studies using BDI, PHQ, and HADS, the pooled prevalence of depression was 50%, 20%, and 15%, respectively.

CONCLUSIONS

ALS people have a high prevalence of depression. The high prevalence of depression causes a reduction of quality of life and mobility. The study identifies a population group at high risk needing special attention in clinical practice.

Pathophysiology and Treatment of Non-motor Dysfunction in Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disease typically presenting with bulbar or limb weakness. There is increasing evidence that amyotrophic lateral sclerosis is a multisystem disease with early and frequent impacts on cognition, behaviour, sleep, pain and fatigue. Dysfunction of normal physiological and metabolic processes also appears common. Evidence from pre-symptomatic studies and large epidemiological cohorts examining risk factors for the future development of amyotrophic lateral sclerosis have reported a high prevalence of changes in behaviour and mental health before the emergence of motor weakness. This suggests that changes beyond the motor system are underway at an early stage with dysfunction across brain networks regulating a variety of cognitive, behavioural and other homeostatic processes. The full impact of non-motor dysfunction continues to be established but there is now sufficient evidence that the presence of non-motor symptoms impacts overall survival in amyotrophic lateral sclerosis, and with up to 80% reporting non-motor symptoms, there is an urgent need to develop more robust therapeutic approaches. This review provides a contemporary overview of the pathobiology of non-motor dysfunction, offering readers a practical approach with regard to assessment and management. We review the current evidence for pharmacological and non-pharmacological treatment of non-motor dysfunction in amyotrophic lateral sclerosis and highlight the need to further integrate non-motor dysfunction as an important outcome measure for future clinical trial design.

Differential Neuropsychological Profile of Patients With Amyotrophic Lateral Sclerosis With and Without C9orf72 Mutation

OBJECTIVE

To determine whether the neuropsychological profiles of patients with amyotrophic lateral sclerosis (ALS) with (ALSC9+) and without (ALSC9-) C9orf72 expansion are different, we administered a battery of neuropsychological tests to 741 patients with ALS (68 ALSC9+ and 673 ALSC9-) and 129 controls.

METHODS

The study population includes 741 patients with ALS who were consecutively diagnosed at the Turin ALS expert center in the 2010-2018 period and who underwent both cognitive/behavioral and genetic testing. Patients' neuropsychological patterns were compared (1) at the same degree of cognitive and behavioral deficit according to the revised ALS-Frontotemporal Dementia Consensus Criteria and (2) at the same level of motor impairment according to the King staging system.

RESULTS

Despite being about 7 years younger, ALSC9+ patients had significantly lower scores in tests exploring executive function and verbal memory both when classified as cognitively normal and when diagnosed in the intermediate cognitive categories. Considering the clinical perspective, ALSC9+ patients showed significantly lower scores compared to ALSC9- patients at King stage 1 and 3 in almost all the examined neuropsychological domains; at King stage 2, ALSC9+ patients were more severely affected only in the verbal memory domain. Behavioral function was comparably impaired in the 2 cohorts.

CONCLUSIONS

ALSC9+ patients show a different neuropsychological profile compared to ALSC9- patients, being more impaired in executive functions and verbal memory domains at all King stages. Verbal memory emerged as a particularly vulnerable function in ALSC9+, with worse performances even when patients were still classified as cognitively normal.

Does a lack of social support and perceived stigma influence the relationship between motor neurone disease-related stress and psychological distress?

OBJECTIVES

This study aimed to investigate the mechanisms through which social support and felt stigma influence the relationship between motor neurone disease (MND)-related stress and psychological distress for people with MND. Although a lack of social support has been identified as a significant predictor of psychological distress for individuals with MND, the mechanisms through which this relationship exists have not been assessed, nor have the predictive nature of stigma. Furthermore, the theoretical model specifying the effects of enacted stigma on self-stigma has not been tested in individuals with MND.

DESIGN

A cross-sectional design utilizing an online survey method was used. It was hypothesized that social support would moderate the relationship between MND-related stress (operationalized as enacted stigma or physical functioning) and psychological distress (operationalized as depression, anxiety, and stress). Furthermore, felt stigma would significantly mediate the relationship between MND-related stress (enacted stigma) and psychological distress.

METHODS

Individuals with a diagnosis of MND were recruited internationally through social media and through various organizations and support services. Seventy-seven participants completed the online survey.

RESULTS

Significant correlations were identified between social support, felt, and enacted stigma and psychological distress. Moderation analysis was not significant. However, the mediation analyses identified felt stigma as a significant mediator of the relationship between enacted stigma and psychological distress. A direct relationship between enacted stigma and stress (but not depression and anxiety) was also evident.

CONCLUSIONS

A comprehensive approach to tackling stigma is important in ameliorating psychological distress for people with MND. Limitations of the current study are discussed, along with implications for clinical practice.

Do pain, anxiety and depression influence quality of life for people with amyotrophic lateral sclerosis/motor neuron disease? A national study reconciling previous conflicting literature

INTRODUCTION

The importance of elucidating the relationships between pain, mood and quality of life (QoL) amongst people with amyotrophic lateral sclerosis/motor neuron disease is evident to clinicians, yet the literature is limited and inconsistent. We explored the relationships between pain, depression, anxiety and QoL to reconcile the previous contrasting findings and inform future research and clinical practice.

METHODS

Patient-reported outcomes were obtained as part of the Trajectories of Outcomes in Neurological Conditions study. Mood and QoL scales underwent Rasch analysis. Correlation coefficients examined the strength of association between variables of interest. A bivariate regression model was developed to examine the effects of pain, depression and anxiety on joint psychological and physical QoL domains.

RESULTS

Of 636 people with ALS, 69% reported pain, of these most had mild pain. Seven percent (7%) of participants exceeded published cutoffs for probable depression and 14% had probable anxiety. Pain, depression and anxiety all influence quality of life; depression has a significant effect on both physical and psychological domains of QoL, whereas pain affects physical QoL and anxiety psychological QoL.

CONCLUSIONS

These results show the importance of expressing quality of life in a conceptually appropriate way, as failing to take account of the multidimensional nature of QoL can result in important nuances being overlooked. Clinicians must be aware that pain, depression and anxiety all worsen QoL across their ranges, and not just when pain is severe or when anxiety or depression reach case level.

Novel behavioural characteristics of the superoxide dismutase 1 G93A (SOD1G93A ) mouse model of amyotrophic lateral sclerosis include sex-dependent phenotypes

Amyotrophic lateral sclerosis (ALS) involves the rapid degeneration of upper and lower motor neurons leading to weakening and paralysis of voluntary movements. Mutations in copper-zinc superoxide dismutase 1 (SOD1) are a known genetic cause of ALS, and the SOD1 ^G93A mouse has been used extensively to investigate molecular mechanisms in ALS. In recent years, evidence suggests that ALS and frontotemporal dementia form a spectrum disorder ranging from motor to cognitive dysfunctions. Thus, we tested male and female SOD1 ^G93A mice for the first time before the onset of debilitating motor impairments in behavioural domains relevant to both ALS and frontotemporal dementia. SOD1 ^G93A males displayed reduced locomotion, exploration and increased anxiety-like behaviours compared with control males. Intermediate-term spatial memory was impaired in SOD1 ^G93A females, whereas long-term spatial memory deficits as well as lower acoustic startle response, and prepulse inhibition were identified in SOD1 ^G93A mice of both sexes compared with respective controls. Interestingly, SOD1 ^G93A males exhibited an increased conditioned cue freezing response. Nosing behaviours were also elevated in both male and female SOD1 ^G93A when assessed in social paradigms. In conclusion, SOD1 ^G93A mice exhibit a variety of sex-specific behavioural deficits beyond motor impairments supporting the notion of an ALS-frontotemporal spectrum disorder. Thus, SOD1 ^G93A mice may represent a useful model to test the efficacy of therapeutic interventions on clinical symptoms in addition to declining motor abilities.

Cognitive, Emotional and Psychological Manifestations in Amyotrophic Lateral Sclerosis at Baseline and Overtime: A Review

It is now well recognized that, in addition to motor impairment, amyotrophic lateral sclerosis (ALS) may cause extra-motor clinical signs and symptoms. These can include the alteration of certain cognitive functions, impaired social cognition, and changes in the perception and processing of emotions. Where these extra-motor manifestations occur in ALS, they usually do so from disease onset. In about 10% of cases, the cognitive and behavioral changes meet the diagnostic criteria for frontotemporal dementia. The timecourse of behavioral and cognitive involvement in ALS is unclear. Whereas longitudinal studies have failed to show cognitive decline over time, some cross-sectional studies have demonstrated poorer cognitive performances in the advanced stages of the disease. Neuroimaging studies show that in ALS, extra-motor signs and symptoms are associated with specific brain lesions, but little is known about how they change over time. Finally, patients with ALS appear less depressed than might be expected, given the prognosis. Moreover, many patients achieve satisfactory psychosocial adjustment throughout the course of the disease, regardless of their degree of motor disability. There are scant longitudinal data on extra-motor impairment in ALS, and to our knowledge, no systematic review on this subject has yet been published. Even so, a better understanding of patients' clinical trajectory is essential if they are to be provided with tailored care and given the best possible support. We therefore undertook to review the evidence for extra-motor changes and their time course in ALS, in both the cognitive, emotional and psychological domains, with a view to identifying mechanisms that may help these patients cope with their disease.

Factors associated with disease-specific quality of life in Taiwanese patients with ankylosing spondylitis: a cross-sectional study

OBJECTIVE

The aim of this study was to assess the factors associated with disease-specific quality of life in Taiwanese patients with ankylosing spondylitis.

DESIGN

A cross-sectional study.

SETTING

A regional teaching hospital in southern Taiwan.

PARTICIPANTS

Adult patients with ankylosing spondylitis recruited from the outpatient rheumatology clinics of the study hospital.

PRIMARY OUTCOME MEASURE

Disease-specific quality of life assessed by the Evaluation of Ankylosing Spondylitis Quality of Life (EASi-QoL).

RESULTS

Of the 265 patients, 57% were 20-49 years of age, with a male preponderance (75.5%). Multiple stepwise linear regression analysis indicated that a higher disease activity, assessed by the Ankylosing Spondylitis Disease Activity Score, was significantly and independently associated with a lower quality of life in all four domains (physical function, disease activity, emotional well-being and social participation) of the EASi-QoL. In addition, various independent factors, including educational level, nature of occupation, disease duration, dietary habit and body mass index, were significantly associated with different domains of the EASi-QoL.

CONCLUSIONS

Our findings indicated that, in addition to disease activity and perceived health status, a number of other factors could significantly impact the different aspects of quality of life in patients with ankylosing spondylitis, which warrant special consideration and support from healthcare providers.

Assessing anxiety and its correlates in amyotrophic lateral sclerosis: The state-trait anxiety inventory

INTRODUCTION

We evaluated: (1) psychometric properties of State-Trait Anxiety Inventory Form Y (STAI Form Y); (2) clinical correlates of state and trait anxiety; (3) associations of anxiety with quality of life (QoL) dimensions.

METHODS

We assessed 159 patients with amyotrophic lateral sclerosis (ALS) on STAI Form Y and on tests and questionnaires for depression, apathy, QoL, and cognitive abilities.

RESULTS

Clinically diagnosed anxiety (by Mini International Neuropsychiatric Inventory) occurred in 30 (19%) patients. STAI Form Y fitted a 2-factor structure and showed good psychometric properties. State and trait anxiety were weakly associated with female sex, bulbar functional decay, and cognitive decline in language and memory; trait anxiety was associated with lower educational attainment and poorer scores on visuospatial tasks. State and trait anxiety were associated with poorer physical and psychosocial QoL dimensions.

CONCLUSIONS

Anxiety is tightly associated with QoL in ALS, and can be reliably assessed by STAI Form Y. Muscle Nerve, 2019.

Disease progression impacts health-related quality of life in amyotrophic lateral sclerosis

OBJECTIVES

To determine the impact of disease progression on health-related quality of life in amyotrophic lateral sclerosis (ALS).

METHODS

A total of 161 patients with ALS were enrolled. Assessments included the revised ALS Functional Rating Scale and the ALS Assessment Questionnaire (ALSAQ-40). Data analysis comprised linear regression and multivariate analyses.

RESULTS

ALSFRS-R score (β = 0.75, p < 0.001), depression (β = 0.08, p < 0.001), pain (β = 0.07, p < 0.001), hopelessness (β = 0.07, p = 0.001), and progression rate (β = 0.02, p = 0.02) explained 76% of the ALSAQ-40 summary index variance. Progression rate alone explained 7% of the ALSAQ-40 summary index variance. The subdomains of emotional well-being, followed by ADL, and finally communication and eating were most strongly influenced by progression rate.

CONCLUSION

Our study demonstrates the importance of physical health for emotional well-being. In particular, slower disease progression is associated with higher levels of emotional well-being in ALS.

Death Anxiety and Depression in Amyotrophic Lateral Sclerosis Patients and Their Primary Caregivers

Background: Given the lethal severity of amyotrophic lateral sclerosis (ALS), the aim of this study was to illuminate the coherence of depression and death anxiety in both ALS patients and caregivers and in how far patients and caregivers are influenced by the mindset of their respective counterpart. Methods: 30 couples of patients (mean age 60.57; 13 women, 17 men) and primary caregivers (mean age 57.33; 16 women, 14 men) were included into the study. Death anxiety was assessed using the newly developed BOFRETTA scale, depression via Beck Depression Inventory, anxiety by means of State Trait Anxiety Inventory and caregivers' exertion using the Caregiver Strain Index. Patients' impairment was assessed with the ALS functional rating scale. Results: We found that while death anxiety was related to depression in both patients and caregivers, death anxiety was related to anxiety only in patients. Caregiver strain correlated with both caregiver's depression and anxiety. Moreover, patients' and caregivers' depression, anxiety and death anxiety correlated to the ones of their counterpart. Conclusion: These results suggest that despite little depressive symptoms in ALS patients the fatal prognosis of the disease takes into account, depression and death anxiety influence each other and might be addressed together in pharmacological and especially psychotherapeutic interventions to the benefit of the patient. Medical professionals should not forget to offer sufficient support to caregivers tending patients affected by depression and death anxiety as they are likely to mirror their patient's feelings.

Caregiver experience, health-related quality of life and life satisfaction among informal caregivers to patients with amyotrophic lateral sclerosis: A cross-sectional study

AIMS AND OBJECTIVES

This study set out to describe caregiver experience, health-related quality of life and life satisfaction among informal caregivers to patients with amyotrophic lateral sclerosis and to explore factors associated with caregivers' health-related quality of life and life satisfaction.

BACKGROUND

Knowledge about factors related to caregivers' health-related quality of life and life satisfaction is important for identification of those at risk for ill health and for development of support and care.

DESIGN

A cross-sectional study.

METHODS

Forty-nine informal caregivers and 49 patients were included. Standardised and study-specific questionnaires were used for data collection on caregiver experience (Caregiver Reaction Assessment), health-related quality of life (EuroQol Visual Analogue Scale, SF-36), life satisfaction (Life Satisfaction Checklist) and caregiver- and patient-related factors. Associations were explored by regression analyses.

RESULTS

Both positive and negative caregiver experience were reported, and health-related quality of life and life satisfaction were below national reference values. Positive experience was associated with better and negative with worse mental health-related quality of life. Factors related to informal caregivers (sex, age, living conditions) and patients (anxiety and/or depression) were related to caregivers' health-related quality and life satisfaction.

CONCLUSION

The results indicate the need to consider the individual caregiver's experience when planning services, care and support. It is important to adopt person-centred care, not only for patients but also for their informal caregivers, as factors related to both parties were associated with the informal caregivers' health-related quality of life and life satisfaction.

RELEVANCE TO CLINICAL PRACTICE

Our study suggests that promoting positive experience and providing services and support to reduce negative aspects of caregiving might be important strategies for healthcare personnel to improve informal caregivers' health.

Mutual support groups for family caregivers of people with amyotrophic lateral sclerosis in Italy: A pilot study

Family caregivers of people with amyotrophic lateral sclerosis (ALS) live stressful lives in which they spend most of their time caring for their loved ones and managing difficult situations, thereby reducing the time spent in taking care of themselves. This situation may last several years. Previous literature has widely highlighted that this situation reduces caregivers' quality of life and increases their psychological distress and risk of health problems, but there is a lack of studies that focus on psychological interventions for these situations. This qualitative study examined a pilot experience of two mutual support groups for family caregivers of people with ALS. The aim was to identify caregivers' needs, the prominent aspects of their experience, and to understand whether and how this intervention strategy might help them. Six partners (four men and two women) and six adult children (five women and one man) participated in the groups, which were conducted in northern Italy. After the support groups finished, participants underwent semi-structured interviews. The authors conducted a content analysis of the transcripts of the interviews and the 20 group sessions. The thematic areas identified were "caregiving," "being the son/daughter of a person with ALS," "being the partner of a person with ALS," "group experience" and "group evaluation." The caregiving experience was profoundly different depending on whether the caregiver was a son/daughter or a partner of a patient with ALS. Moreover, comparison with peers and mutual support helped participants to better cope with ALS and its consequences, to improve their care for their relatives and to overcome typical caregiver isolation. These results suggest the usefulness of involving communities in caregiver support in order to create new networks and activate personal and social resources for well-being.

Discussing edaravone with the ALS patient: an ethical framework from a U.S. perspective

The recent approval of edaravone by the United States Food and Drug Administration has generated a mix of hope tempered by reality. The costs of the drug, both monetarily and with regard to intensity of treatment, are high. The benefits, while modest, will be viewed through a very different lens by individuals depending on their goals of care. By virtue of our training and experience, physicians are ideally suited to understand and explain new treatments to our patients. As healthcare providers with a fiduciary responsibility to our patients, we must make sure they are fully informed about both the costs and benefits of non-curative therapies such as edaravone, and be prepared to discuss these in the context of their goals of care and potential impact on quality of life. Respect for our patients' autonomy is critical when discussing these issues, but we should always be guided by the ethical principles of beneficence and non-maleficence.

A prospective study of quality of life in amyotrophic lateral sclerosis patients

OBJECTS

The aim of this prospective and longitudinal study was to describe individual quality of life in patients with amyotrophic lateral sclerosis (ALS) and its correlations with physical function and emotional well-being from diagnosis and over time.

MATERIALS AND METHODS

Thirty-six patients were included in the study. Individual quality of life was measured with the Schedule of Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW), illness severity was assessed using the Amyotrophic Lateral Sclerosis Functional Rating Scale (ALS FRS-R), and emotional distress was measured using the Hospital Anxiety and Depression Scale (HADS). Data were collected from diagnosis and thereafter, every six months for a period of two years. Twelve patients completed the 24-month follow-up.

RESULTS

Family, friends and own physical health were important for overall quality of life, from diagnosis and during the disease progression. Most patients had good quality of life, which remained stable, despite changed physical functions. Several patients scored above the cut-off score for doubtful and clinical anxiety and depression early on after diagnosis, and there was a significant decrease in anxiety over time. Soon after diagnosis, there was a correlation between depression and quality of life.

CONCLUSION

The family, social relations and own physical health are important for overall quality of life in patients with ALS. Thus, supporting the family and facilitating so that patients can continue to stay in contact with friends are important aspects during the disease. Conducting an early screening for depression can be important for preventing decreased quality of life.

Care management in amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is a relentlessly progressive and fatal neurodegenerative disease characterized by progressive weakness of voluntary muscles of movement as well as those for swallowing, speech and respiration. In the absence of curative treatment, care can improve quality of life, prolong survival, and support ALS patients and their families, and also help them to anticipate and prepare for the end of life. Multidisciplinary management in tertiary centers is recommended in close collaboration with general practitioners, home carers and a dedicated health network. Patients' follow-up deals mainly with motor impairment and physical disability, adaptation, nutrition and respiratory function. Involvement of palliative care as part of the multidisciplinary team management offers patients the possibility of discussing their end of life issues. This review summarizes the different aspects of ALS care, from delivering the diagnosis to the end of life, and the organization of its management.

Coping strategies and psychological distress in caregivers of patients with Amyotrophic Lateral Sclerosis (ALS)

BACKGROUND

Amyotrophic lateral sclerosis (ALS) causes distress in caregivers. The present study aims to examine the association between coping strategies and psychological distress in caregivers of ALS patients.

METHODS

Coping strategies were assessed in 96 ALS informal caregivers by means of the Coping Inventory for Stressful Situations. Data about caregivers' demographic characteristics, levels of burden, depression and anxiety (psychological distress) were also gathered by standardised questionnaires. Patients' clinical, cognitive and behavioural disturbances were evaluated by ALS specific assessment tools.

RESULTS

Sequential logistic regression analysis showed that emotion-oriented coping strategy was significantly associated with high levels of depressive (p < 0.01) and anxiety (p < 0.05) symptoms and high levels of burden (p < 0.05), after controlling for all other variables. Moreover, a significant relationship of patients' functional dependence levels with burden experienced by caregivers was observed. No relationships were detected between task-oriented and avoidance-oriented coping strategies and caregivers' levels of psychological distress.

CONCLUSIONS

The present study supported the mediating effects of coping strategies on intensity of burden, depression and anxiety experienced by ALS caregivers. These findings suggest that interventions aimed at reducing utilisation of maladaptive coping strategies may improve well-being in ALS caregivers, and, possibly, management of symptoms in ALS patients.

Predictors of health-related quality of life in people with amyotrophic lateral sclerosis

BACKGROUND

Knowledge of factors influencing health-related quality of life (HRQL) in people with amyotrophic lateral sclerosis (ALS) is important because some factors might be amenable to intervention.

OBJECTIVES

The aim was to describe and explore the effects of disease severity, fatigue, anxiety, depression, frequency of social and lifestyle activities, coping capacity and mechanical ventilator use on HRQL in people with ALS.

METHODS

Sixty people with ALS were enrolled in this cross-sectional study. Data were collected with questionnaires during home visits. The Sickness Impact Profile and the EuroQol Visual Analogue Scale were used to assess HRQL. Multivariate regression analyses explored associations between HRQL and independent factors.

RESULTS

Low frequency of social and lifestyle activities, and severe disease, were associated with worse HRQL, explaining 57% of total variance in the Sickness Impact Profile physical score. Severe disease, weak coping capacity and anxiety and/or depression were associated with worse HRQL, explaining 33% of total variance in Sickness Impact Profile psychosocial score. Fatigue and mechanical ventilator use were associated with worse HRQL, explaining 17% of variance in the EuroQol Visual Analogue Scale.

CONCLUSION

Knowledge and understanding of how frequency of social and lifestyle activities, disease severity, coping capacity, anxiety and/or depression, fatigue and ventilator use contribute to and predict self-rated HRQL can optimize person-centred care and support.

Associations between psychological factors and health-related quality of life and global quality of life in patients with ALS: a systematic review

OBJECTIVE

To systematically identify and appraise evidence on associations between psychological factors (moods, beliefs, personality) and Health-related QoL (HRQoL) and/or global QoL in patients with Amyotrophic Lateral Sclerosis (ALS).

METHODS

A systematic review was conducted in several online databases (PsycINFO, EMBASE, PubMed and CINAHL) up to October 2015. Articles were included if they reported associations between psychological factors (moods, beliefs and personality) and HRQoL and/or global QoL in an ALS population. The search was limited to empirical studies, published in English, which provided quantitative data. The methodological quality of the included articles was assessed.

RESULTS

In total, 22 studies were included. Mood was investigated in 14 studies, beliefs in 11 studies and personality in one study. Fifteen different psychological factors were extracted and assessed using 24 different measures. Twelve different QoL measures were used in the selected studies, subdivided into seven different HRQoL measures and five different global QoL measures. Higher levels of anxiety and depression appeared to be related to a poorer HRQoL, whereas a higher level of religiosity seemed to be associated with better global QoL. No conclusive associations were found for confusion-bewilderment (mood), spirituality, mindfulness, coping styles, hopelessness, perception of burden, cognitive appraisal (beliefs), neuroticism, extraversion, openness, agreeableness and conscientiousness (personality), due to insufficient or inconsistent evidence. Religiosity and spirituality appeared to become more positively associated over time.

CONCLUSIONS

Our results suggest that higher levels of anxiety and depression are related to a poorer HRQoL, whereas higher levels of religiosity appeared to be related to better global QoL. Associations might change during the disease course. This review supports the importance of psychological factors with regard to ALS care. Further research is needed to supplement the available evidence and to investigate how psychological factors can be modified to improve QoL.

Symptom Management and End-of-Life Care in Amyotrophic Lateral Sclerosis

The number of available symptomatic treatments has markedly enhanced the care of patients with amyotrophic lateral sclerosis (ALS). Once thought to be untreatable, patients with ALS today clearly benefit from multidisciplinary care. The impact of such care on the disease course, including rate of progression and mortality, has surpassed the treatment effects commonly sought in clinical drug trials. Unfortunately, there are few randomized controlled trials of medications or interventions addressing symptom management. In this review, the authors provide the level of evidence, when available, for each intervention that is currently considered standard of care by consensus opinion.

A Qualitative Study of Multidisciplinary ALS Clinic Use in the United States

OBJECTIVES

The multidisciplinary clinic (MDC) has become the standard of care for individuals with amyotrophic lateral sclerosis (ALS) in the United States, yet many patients choose not to receive care at MDCs. We undertook a qualitative study of individuals with ALS to explore patients' perceptions of this form of service delivery.

METHODS

Participants completed an online survey that posed open-ended questions about their attitudes and behaviors surrounding MCDs. Qualitative analysis was performed whereby response data was evaluated and grouped into themes.

RESULTS

The unique aspect of MDCs most commonly cited by patients was integrated care. Other reasons for attending MDC included those common to specialist centers, such as expertise, access to clinical trials, and participation in research. Perceived disadvantages unique to the MDC model were long and tiring visits. In common with many specialist centers, long travel times were cited as a disadvantage of MDCs.

CONCLUSIONS

This information provides a foundation for improving ALS care. For those able to travel, the MDC model has much to offer, but patients' time should be respected. For those patients who cannot travel, alternative models of care should be devised to provide integrated care, clinical expertise, and access to research.

Hypnosis-based psychodynamic treatment in ALS: a longitudinal study on patients and their caregivers

Background: Evidence of psychological treatment efficacy is strongly needed in ALS, particularly regarding long-term effects.

Methods: Fifteen patients participated in a hypnosis treatment and self-hypnosis training protocol after an in-depth psychological and neurological evaluation. Patients' primary caregivers and 15 one-by-one matched control patients were considered in the study. Measurements of anxiety, depression and quality of life (QoL) were collected at the baseline, post-treatment, and after 3 and 6 months from the intervention. Bayesian linear mixed-models were used to evaluate the impact of treatment and defense style on patients' anxiety, depression, QoL, and functional impairment (ALSFRS-r), as well as on caregivers' anxiety and depression.

Results: The statistical analyses revealed an improvement in psychological variables' scores immediately after the treatment. Amelioration in patients' and caregivers' anxiety as well as caregivers' depression, were found to persist at 3 and 6 months follow-ups. The observed massive use of primitive defense mechanisms was found to have a reliable and constant buffer effect on psychopathological symptoms in both patients and caregivers. Notably, treated patients decline in ALSFRS-r score was observed to be slower than that of control group's patients.

Discussion: Our brief psychodynamic hypnosis-based treatment showed efficacy both at psychological and physical levels in patients with ALS, and was indirectly associated to long-lasting benefits in caregivers. The implications of peculiar psychodynamic factors and mind-body techniques are discussed. Future directions should be oriented toward a convergence of our results and further psychological interventions, in order to delineate clinical best practices for ALS.

Patient-Perceived Outcomes and Quality of Life in ALS

A variety of outcome measures are used in clinical practice and in research to assess patients with amyotrophic lateral sclerosis (ALS). However, there may be discordance between traditional outcome measures such as strength and physical function, and patient-perceived measures of well-being. One such self-perceived measure, reflecting the patient's view, is quality of life (QOL). QOL in patients with severe medical disorder is often underestimated by others. Patients with ALS often have high QOL, and this may persist throughout the disease due to shifting expectations and to reprioritization of factors contributing to QOL. QOL instruments can measure health-related QOL (HRQOL) or global QOL, and can be generic or disease-specific. HRQOL refers primarily to physical and mental health. Global QOL is much broader, and is also determined by non-health-related factors. The choice of a QOL instrument depends on whether the setting is routine patient care or clinical research, whether or not the outcome of a specific intervention is being assessed, and upon the expected efficacy or toxicity of the intervention. Global QOL instruments are best for individual clinical patient care or for comparing groups. HRQOL or a combination of HRQOL and global QOL instruments are most appropriate for assessing specific interventions.

Depression and anxiety in amyotrophic lateral sclerosis: correlations between the distress of patients and caregivers

INTRODUCTION

Depression and anxiety are common in amyotrophic lateral sclerosis (ALS) patients and caregivers.

METHODS

In this study we investigated 93 ALS patients and their 93 caregivers. Depression and anxiety were quantified by the Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale, respectively.

RESULTS

Very strong correlations between depression and anxiety were found among patients and their caregivers. The severity of depression and anxiety of patients correlated moderately with that of their caregivers. No correlations were found between the severity of depression and anxiety and ALS Functional Rating Scale-Revised (ALSFRS-R) score or for disease duration among patients and caregivers. However, severity of depression and anxiety in caregivers correlated with their age.

CONCLUSIONS

Depression and anxiety in ALS patients and their caregivers were associated closely with each other but not with physical disability or disease duration in our Chinese population.

Frequency and risk factor analysis of cognitive and anxiety-depressive disorders in patients with amyotrophic lateral sclerosis/motor neuron disease

OBJECTIVES

To examine the frequency and risk factors of cognitive and anxiety-depressive disorders in patients with amyotrophic lateral sclerosis/motor neuron disease (ALS/MND).

METHODS

This was an observational study of 100 ALS/MND patients treated at our hospital outpatient and inpatient departments between January 2009 and April 2010 and 100 matched healthy controls. Subjects were surveyed using Mini Mental State Examination (MMSE), Zung Self-Rating Anxiety Scale (SAS), and Zung Self-Rating Depression Scale (SDS). Patient neurological status was graded by the ALS Functional Rating Scale (ALSFRS). Multivariate linear regression was used to identify factors associated with the MMSE, SAS, SDS, and ALSFRS scores.

RESULTS

Patients had significantly lower MMSE scores than controls (P<0.05). MMSE score did not differ by sex or age (<50/≥50 years) (P>0.05). Patients with higher educational level (college and above), shorter disease course (<2 years), and lower ALSFRS score (<20) had significantly higher MMSE scores (all P<0.05). Multivariate analysis revealed that higher education, shorter disease course, and lower ALSFRS score were independent predictors of better cognitive function (higher MMSE score). Patients had significantly higher mean SAS and SDS total scores than controls (both P<0.05), indicating higher subjective anxiety and depression. Female patients, patients with higher education, and those with higher ALSFRS scores had significantly higher SAS and SDS scores (all P<0.05). Age, occupation, diagnostic classification, disease duration, and disease awareness did not influence SAS or SDS scores. Multivariate analysis indicated that lower education and lower ALSFRS were protective factors against anxiety and depression.

CONCLUSION

The frequency of anxiety-depressive disorders was high among patients with ALS/MND. High educational level, short course of disease, and lower ALSFRS were associated with preserved cognitive function. Female sex, higher education, and lower ALSFRS score conferred a greater risk of anxiety and depression. Tailored pharmacotherapy and psychological interventions may help in reducing anxiety and depression in these patients.

A longer diagnostic interval is a risk for depression in amyotrophic lateral sclerosis

Objective:

Recognizing depressive symptoms in patients with amyotrophic lateral sclerosis (ALS) remains problematic given the potential overlap with the normal psychological responses to a terminal illness. Understanding mental health and disease-related risk factors for depression is key to identifying psychological morbidity. The present study aimed to determine the prevalence of depressive symptoms in ALS and to explore mental health and disease-related risk factors for depression.

Method:

Structured medical and psychiatric history questionnaires and a validated depression scale (Depression, Anxiety, Stress Scale–21) were completed by 27 ALS patients (60% female; 59% limb onset; age 65.11 ± SE 2.21) prior to their initial review at a multidisciplinary clinic. Physical function was assessed with the Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS–R).

Results:

At the time of initial assessment, 44% of patients had a previous psychiatric history, although the majority (62%) reported no symptoms of depression. The mean ALSFRS–R score was 37.78 ± SE 1.22, with an average diagnostic interval of 16.04 ± SE 2.39 months. Logistic regression analysis revealed that the length of the diagnostic interval alone predicted depressive symptoms (χ2(3, n = 26) = 9.21, Odds Ratio (OR) = 1.12, p < 0.05.

Significance of Results:

The illness experiences of ALS patients rather than established mental health risk factors influence the manifestation of depressive symptoms in the early stages of the disease, with clinical implications for the assessment and treatment of psychological morbidity. Patients with lengthy diagnostic intervals may be prime targets for psychological assessment and intervention, especially in the absence of ALS-specific tests and biomarkers.

Dysfunctions within limbic-motor networks in amyotrophic lateral sclerosis

Previous studies have shown that affective symptoms are part of the clinical picture in amyotrophic lateral sclerosis (ALS), the most common motor neuron disorder in elderly people. Diffuse neurodegeneration of limbic regions (e.g., prefrontal cortex [PFC], amygdala) was demonstrated in ALS post-mortem, although the mechanisms of emotional dysregulation in ALS in vivo remain unclear. Using functional imaging, we assessed the brain responses to emotional faces in 11 cognitively unimpaired ALS patients and 12 healthy controls (HCs). We tested whether regional activities and connectivity patterns in the limbic system differed between ALS patients and HCs and whether the variability in clinical measures modulated the neuroimaging data. Relative to HCs, ALS patients displayed greater activation in a series of PFC areas and altered left amygdala-PFC connectivity. Anxiety modulated the right amygdala-PFC connectivity in HCs but not in ALS patients. Reduced right premotor cortex activity and altered left amygdala-supplementary motor area connectivity were associated with longer disease duration and greater disease severity, respectively. Our findings demonstrate dysfunctions of the limbic system in ALS patients at early stages of the disease, and extend our knowledge about the interplay between emotional brain areas and the regions traditionally implicated in motor control.

A 10-year literature review of family caregiving for motor neurone disease: moving from caregiver burden studies to palliative care interventions

BACKGROUND

There is growing awareness that different terminal diseases translate into different family caregiver experiences, and the palliative and supportive care needs of these families are both similar and unique. Family members caring for people with motor neurone disease may experience exceptional strain due to the usually rapid and progressive nature of this terminal illness.

AIM

The purpose of this review is to synthesize contemporary research and provide a comprehensive summary of findings relevant to motor neurone disease family caregivers, as well as highlight some of the suggested interventions to alleviate burden and improve quality of life for this group.

DESIGN

We conducted a comprehensive review of empirical research on family caregiving for people with motor neurone disease in peer-reviewed journals published in English, January 2000-April 2011. Fifty-nine studies met the inclusion criteria.

RESULTS

This comprehensive literature review was consistent with previous research documenting the substantial burden and distress experienced by motor neurone disease family caregivers and revealed important points in the trajectory of care that have the potential for negative effects. The diagnosis experience, assisted ventilation, cognitive changes and end-of-life decision making create challenges within a short time. This review has also implicated the need for improvements in access to palliative care services and highlighted the absence of interventions to improve care.

CONCLUSIONS

Caregiver burden and quality-of-life studies on motor neurone disease family caregivers have so far dominated the research landscape .The focus needs to be on developing interventions that provide direct practical and psychosocial supports for motor neurone disease family caregivers.

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.

Psychische Störungen und individuelle Lebensqualität bei der chronisch progredient-terminalen Erkrankung „Amyotrophe Lateralsklerose (ALS)”

Theoretischer Hintergrund: Die Krankheitsbewältigung spielt eine wichtige Rolle für die psychische Gesundheit und das Wohlbefinden von Patienten mit amyotropher Lateralsklerose (ALS). Fragestellung: Die vorliegende Studie untersuchte Angst, Depression und individuelle Lebensqualität sowie assoziierte Faktoren bei ALS. Methode: Die Stichprobe umfasste 39 ALS-Patienten (20 Frauen, Durchschnittsalter 58 Jahre, Durchschnitts-Erkrankungsdauer 2.4 Jahre). Eingesetzt wurden die Sektionen A, D, F und teilweise J des SKID-I, das ALS-Depressionsinventar (ADI-12), der Schedule for the Evaluation of Individual Quality of Life–Direct Weigthening (SEIQoL-DW) und die Liste zur Erfassung von Verstärkern (LEV). Ergebnisse: Auftretenshäufigkeiten für eine Major Depression Episode: 10 %, für depressive Störungen insgesamt: 23 %, für Angststörungen: 21 %. Die Erstmanifestation einer Major Depression lag bei 4 von 9 Patienten vor der ALS-Diagnose. Nur die Hälfte der Patienten mit der Depressions-Lebenszeitdiagnose erlebte nach der ALS-Diagnose eine weitere Episode. Depressionen waren assoziiert mit weiblichem Geschlecht, einem geringeren Bildungsniveau, geringerer Lebensqualität und einer geringeren Anzahl positiv verstärkender Aktivitäten. Die individuelle Lebensqualität (iLQ) lag bei 72 von 100. Depressive Patienten zeigten dabei eine stärkere Orientierung auf die Gesundheit als nicht depressive Patienten. Schlussfolgerung: Trotz hoher individueller Lebensqualität traten Depressionen und Angststörungen gehäuft auf. Psychotherapeutische Unterstützung ist angezeigt, vor allem im Sinne einer Einstellungs- und Werteveränderung, beim Aufbau oder Erhalt von Verstärkern sowie als kognitive Therapie bei erlebtem Kontrollverlust.

Caregiver burden in amyotrophic lateral sclerosis is more dependent on patients' behavioral changes than physical disability: a comparative study

Background

Behavioral changes in patients with amyotrophic lateral sclerosis (ALS) mirror those found in frontotemporal dementia (FTD). Considering the high rate of neuropsychiatric symptoms found in ALS patients, this paper examines whether caregiver burden is associated with behavioral changes over and above the physical disability of patients with ALS, and if the presence of caregivers’ depression, anxiety and stress also impacts on caregiver burden.

Methods

140 caregivers of patients with ALS participated in a postal survey investigating patients’ neuropsychiatric symptoms (Cambridge Behaviour Inventory Revised CBI-R), motor function (Amyotrophic Lateral Sclerosis Functional Rating Scale Revised - ALSFRS-R), caregiver burden (Zarit Burden Interview), and caregiver mood (Depression, Anxiety and Stress Scale- DASS21). Seventy four percent of them were caregivers of patients with limb onset and 25.7% were caregivers of patients with bulbar onset.

Results

Moderate to severe behavioral changes were reported in 10-40% of patients with ALS. The levels of depression, anxiety and stress in the caregivers reached 20%. Burden was high in 48% of the caregivers. The strongest predictor of high caregiver burden was ALS patients’ abnormal behavior rather than physical disability, with an odds ratio of 1.4, followed by caregivers’ stress.

Conclusions

Our study has identified that behavioral changes (e.g. disinhibition, impulsivity) and caregiver stress have greater impact on caregiver burden than level and pattern of physical disability.

Social support associated with quality of life in home care patients with intractable neurological disease in Japan

The aim of the present study was to investigate what kinds of social supports contribute to the higher quality of life (QOL) of home care patients with intractable neurological disease. We investigated the World Health Organization Quality of Life-BREF (WHOQOL-BREF) and social supports to 74 patients with intractable neurological disease in a city of the Aichi prefecture, Japan. Association between WHOQOL and social supports was examined using multiple logistic regression analyses adjusting activities of daily living (ADL). High WHOQOL scores were associated with “attending patient gatherings held by the public health center,” “having someone who will listen empathically to anxieties or troubles,” and ADL. Physical health was associated with ADL, while psychological well-being was related to “having a hobby,” “having someone who will listen,” and “having a hospital for admission in emergencies.” Patients not having someone who will listen were more likely to participate in the gatherings. The present findings suggest that having someone who will provide emotional support is important for home care patients with neurological diseases. Patient gatherings held by the public health center were expected to provide patients with emotional support.
