Abstract
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive degeneration of both upper and lower motor neurons. A defining histopathological feature in approximately 97% of all ALS cases is the accumulation of phosphorylated trans-activation response (TAR) DNA-binding protein 43 protein (pTDP-43) aggregates in the cytoplasm of neurons and glial cells within the central nervous system. Traditionally, it was believed that the accumulation of TDP-43 aggregates and subsequent neurodegeneration primarily occurs in motor neurons. However, contemporary evidence suggests that as the disease progresses, other systems and brain regions are also affected. Despite this, there has been a limited number of clinical studies assessing the non-motor symptoms in ALS patients. These studies often employ various outcome measures, resulting in a wide range of reported frequencies of non-motor symptoms in ALS patients. The importance of assessing the non-motor symptoms reflects in a fact that they have a significant impact on patients' quality of life, yet they frequently go underdiagnosed and unreported during clinical evaluations. This review aims to provide an up-to-date overview of the current knowledge concerning non-motor symptoms in ALS. Furthermore, we address their diagnosis and treatment in everyday clinical practice.

Amyotrophic Lateral Sclerosis and Pain: A Narrative Review from Pain Assessment to Therapy. Behav Neurol 2024; 2024:1228194. [PMID: 38524401 PMCID: PMC10960655 DOI: 10.1155/2024/1228194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 02/11/2024] [Accepted: 03/06/2024] [Indexed: 03/26/2024] Open
Abstract
Amyotrophic lateral sclerosis (ALS) is the most frequent neurodegenerative disease of the motor system that affects upper and lower motor neurons, leading to progressive muscle weakness, spasticity, atrophy, and respiratory failure, with a life expectancy of 2-5 years after symptom onset. In addition to motor symptoms, patients with ALS have a multitude of nonmotor symptoms; in fact, it is currently considered a multisystem disease. The purpose of our narrative review is to evaluate the different types of pain, the correlation between pain and the disease's stages, the pain assessment tools in ALS patients, and the available therapies focusing above all on the benefits of cannabis use. Pain is an underestimated and undertreated symptom that, in the last few years, has received more attention from research because it has a strong impact on the quality of life of these patients. The prevalence of pain is between 15% and 85% of ALS patients, and the studies on the type and intensity of pain are controversial. The absence of pain assessment tools validated in the ALS population and the dissimilar study designs influence the knowledge of ALS pain and consequently the pharmacological therapy. Several studies suggest that ALS is associated with changes in the endocannabinoid system, and the use of cannabis could slow the disease progression due to its neuroprotective action and act on pain, spasticity, cramps, sialorrhea, and depression. Our research has shown high patients' satisfaction with the use of cannabis for the treatment of spasticity and related pain. However, especially due to the ethical problems and the lack of interest of pharmaceutical companies, further studies are needed to ensure the most appropriate care for ALS patients.

Abstract
Amyotrophic Lateral Sclerosis (ALS) is a complex and rare neurodegenerative disease given its heterogeneity. Despite being known for many years, few countries have accurate information about the characteristics of people diagnosed with ALS, such as data regarding diagnosis and clinical features of the disease. In Brazil, the lack of information about ALS limits data for the research progress and public policy development that benefits people affected by this health condition. In this context, this article aims to show a digital health solution development and application for research, intervention, and strengthening of the response to ALS in the Brazilian Health System. The proposed solution is composed of two platforms: the Brazilian National ALS Registry, responsible for the data collection in a structured way from ALS patients all over Brazil; and the Brazilian National ALS Observatory, responsible for processing the data collected in the National Registry and for providing a monitoring room with indicators on people diagnosed with ALS in Brazil. The development of this solution was supported by the Brazilian Ministry of Health (MoH) and was carried out by a multidisciplinary team with expertise in ALS. This solution represents a tool with great potential for strengthening public policies and stands out for being the only public database on the disease, besides containing innovations that allow data collection by health professionals and/or patients. By using both platforms, it is believed that it will be possible to understand the demographic and epidemiological data of ALS in Brazil, since the data will be able to be analyzed by care teams and also by public health managers, both in the individual and collective monitoring of people living with ALS in Brazil.

Abstract
Amyotrophic lateral sclerosis (ALS) is a rapidly progressive neurodegenerative condition characterized by loss of motor neurons, resulting in motor weakness of the limbs and/or bulbar muscles. Pain is a prevalent but neglected symptom of ALS, and it has a significant negative impact on the quality of life of patients and their caregivers. This review outlines the epidemiology, clinical characteristics, underlying mechanisms, and management strategies of pain in ALS to improve clinical practice and patient outcomes related to pain. Pain is a prevalent symptom among patients with ALS, with a variable reported prevalence. It may occur at any stage of the disease and can involve any part of the body without a specific pattern. Primary pain includes neuropathic pain and pain from spasticity or cramps, while secondary pain is mainly nociceptive, occurring with the progression of muscle weakness and atrophy, prolonged immobility causing degenerative changes in joints and connective tissue, and long-term home mechanical ventilation. Prior to treatment, the exact patterns and causes of pain must first be identified, and the treatment should be tailored to each patient. Treatment options can be classified into pharmacological treatments, including nonsteroidal anti-inflammatory drugs, antiepileptic drugs, drugs for cramps or spasticity, and opioid; and nonpharmacological treatments, including positioning, splints, joint injections, and physical therapy. The development of standardized and specific assessment tools for pain-specific to ALS is required, as are further studies on treatments to reduce pain, diminish suffering, and improve the quality of life of patients with ALS.

Abstract
For patients diagnosed with a rare musculoskeletal or neuromuscular disease, pain may transition from acute to chronic; the latter yielding additional challenges for both patients and care providers. We assessed the present understanding of pain across a set of ten rare, noninfectious, noncancerous disorders; Osteogenesis Imperfecta, Ehlers-Danlos Syndrome, Achondroplasia, Fibrodysplasia Ossificans Progressiva, Fibrous Dysplasia/McCune-Albright Syndrome, Complex Regional Pain Syndrome, Duchenne Muscular Dystrophy, Infantile- and Late-Onset Pompe disease, Charcot-Marie-Tooth Disease, and Amyotrophic Lateral Sclerosis. Through the integration of natural history, cross-sectional, retrospective, clinical trials, & case studies we described pathologic and genetic factors, pain sources, phenotypes, and lastly, existing therapeutic approaches. We highlight that while rare diseases possess distinct core pathologic features, there are a number of shared pain phenotypes and mechanisms that may be prospectively examined and therapeutically targeted in a parallel manner. Finally, we describe clinical and research approaches that may facilitate more accurate diagnosis, monitoring, and treatment of pain as well as elucidation of the evolving nature of pain phenotypes in rare musculoskeletal or neuromuscular illnesses.

Abstract
In this review, we discuss different aspects of pain syndrome in patients with amyotrophic lateral sclerosis: etiology, incidence, pathophysiology and main clinical features. Also we review the modern approaches to the treatment of pain in amyotrophic lateral sclerosis. Pain is actually not rare in this condition: it appears in 80% of patients, affecting their quality of life and functional activity, leading to the development of depressive and anxiety disorders. Pain in amyotrophic lateral sclerosis is often overlooked by clinicians, since their attention may focus on the motor symptoms of the disease. Thus, a more careful approach is needed to diagnose and treat pain in amyotrophic lateral sclerosis.

Abstract
Purpose: The aim was to explore personal experiences of pain in people with motor neuron disease.Materials and methods: Sixteen participants were individually interviewed on one occasion concerning their experiences of presentation, consequences, and management of pain. Qualitative content analysis with researcher triangulation was used to synthesize and interpret data.Results: Four themes emerged as the result of the analysis: (1) The multiple faces of pain, (2) The thin line between experience of pain and no pain, (3) The negative effects of pain on role functioning (4) Successful coping with pain requiring personal effort and competent engagement. The important findings were the experiences of unpredictability of pain breakthroughs, the efforts required to manage pain, consequences for activity and quality of life, and the suffering induced by diminishment and neglect of pain from both patients and staff.Conclusions: Pain in motor neuron disease seems to have certain and multiple characteristics, which is why there is a need to develop and implement pain assessment methods adapted to this population. Such methods may help make pain more predictable, and increase the possibilities to provide effective and individually tailored pain treatment.IMPLICATIONS FOR REHABILITATIONPain is a common, but often neglected, ailment in motor neuro disease, which deserves more attention from health care.Staff should provide information about the pain being possible to treat successfully with medication, by contrast to the possibility of curing the disease itself.Pain assessments should be implemented during the entire course of the disease, covering a time frame long enough to cover characteristic fluctuations of pain.Whenever possible, facilitate the performance of painful activities of daily living as much as possible to make room for engagement in other personally valued activities of importance for individual quality of life.

Abstract
Our objective was to systematically analyse the first series of cases of amyotrophic lateral sclerosis (ALS) in Minas Gerais and to review the Brazilian literature about clinical studies in ALS. This was a cross-sectional and descriptive study of a consecutive series of patients with probable or defined sporadic ALS according to the Awaji criteria, followed at two referral centres of Belo Horizonte (South-east Brazil). Patients underwent full clinical assessment. Comparisons of patient subgroups according to disease duration and initial presentation were performed. A systematic review was performed about Brazilian clinical studies in ALS. Results showed that of the 61 enrolled patients the male/female ratio was 1.6:1. The mean age at onset of symptoms was 54.9 years (SD ± 11.4). Mean age at diagnosis was 56.3 years (SD ± 11.1). Regarding the initial form of presentation, 43 cases (70.5%) were spinal, 12 cases (19.7%) were generalized and six cases (9.8%) were bulbar. Eight studies were found in the systematic review. In conclusion, the profile of our sample was similar to other national and international series, except for fewer cases of bulbar ALS in our series. There are few clinical studies of ALS in Brazil. The national data of prevalence and incidence are still uncertain.

Abstract
Chronic pain is a debilitating condition with major socioeconomic impact, whose neurobiological basis is still not clear. An involvement of the neurovascular unit (NVU) has been recently proposed. In particular, the blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB), two NVU key players, may be affected during the development of chronic pain; in particular, transient permeabilization of the barrier is suggested by several inflammatory- and nerve-injury-based pain models, and we argue that the clarification of molecular BBB/BSCB permeabilization events will shed new light in understanding chronic pain mechanisms. Possible biases in experiments supporting this theory and its translational potentials are discussed. Moving beyond an exclusive focus on the role of the endothelium, we propose that our understanding of the mechanisms subserving chronic pain will benefit from the extension of research efforts to the NVU as a whole. In this view, the available evidence on the interaction between analgesic drugs and the NVU is here reviewed. Chronic pain comorbidities, such as neuroinflammatory and neurodegenerative diseases, are also discussed in view of NVU changes, together with innovative pharmacological solutions targeting NVU components in chronic pain treatment.

Abstract
BACKGROUND Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is the most common neurodegenerative disorder of the motor system in adults. Pain in ALS is a frequent symptom especially in the later stages of disease and can have a pronounced influence on quality of life and suffering. Treatment of pain therefore should be recognised as an important aspect of palliative care in ALS. This is an update of a review first published in 2008. OBJECTIVES To systematically review the evidence for the efficacy of drug therapy in relieving pain in ALS. We also aimed to evaluate possible adverse effects associated with the different drugs and their influence on survival and quality of life. SEARCH METHODS On 2 July 2012, we searched the following databases: 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), CINAHL (January 1982 to June 2012), AMED (January 1985 to June 2012) and LILACS (January 1982 to June 2012). We checked the bibliographies of trials identified and contacted other disease experts to identify further published and unpublished trials. SELECTION CRITERIA We searched for randomised or quasi-randomised controlled trials on drug therapy for pain in amyotrophic lateral sclerosis. DATA COLLECTION AND ANALYSIS We collected data using a specially designed form and analysed them using the Cochrane Review Manager software. MAIN RESULTS We found no randomised or quasi-randomised controlled trials on drug therapy for pain in ALS or MND. AUTHORS' CONCLUSIONS There is no evidence from randomised controlled trials about the management of pain in ALS. Further research on this important aspect of palliative care in ALS is needed. Randomised controlled trials should be initiated to determine the effectiveness of different analgesics for treatment of pain in ALS.

Abstract
Chronic pain is a frequent component of many neurological disorders, affecting 20-40% of patients for many primary neurological diseases. These diseases result from a wide range of pathophysiologies including traumatic injury to the central nervous system, neurodegeneration and neuroinflammation, and exploring the aetiology of pain in these disorders is an opportunity to achieve new insight into pain processing. Whether pain originates in the central or peripheral nervous system, it frequently becomes centralized through maladaptive responses within the central nervous system that can profoundly alter brain systems and thereby behaviour (e.g. depression). Chronic pain should thus be considered a brain disease in which alterations in neural networks affect multiple aspects of brain function, structure and chemistry. The study and treatment of this disease is greatly complicated by the lack of objective measures for either the symptoms or the underlying mechanisms of chronic pain. In pain associated with neurological disease, it is sometimes difficult to obtain even a subjective evaluation of pain, as is the case for patients in a vegetative state or end-stage Alzheimer's disease. It is critical that neurologists become more involved in chronic pain treatment and research (already significant in the fields of migraine and peripheral neuropathies). To achieve this goal, greater efforts are needed to enhance training for neurologists in pain treatment and promote greater interest in the field. This review describes examples of pain in different neurological diseases including primary neurological pain conditions, discusses the therapeutic potential of brain-targeted therapies and highlights the need for objective measures of pain.

Abstract
Serotonin (5-HT) has been intimately linked with global regulation of motor behavior, local control of motoneuron excitability, functional recovery of spinal motoneurons as well as neuronal maturation and aging. Selective degeneration of motoneurons is the pathological hallmark of amyotrophic lateral sclerosis (ALS). Motoneurons that are preferentially affected in ALS are also densely innervated by 5-HT neurons (e.g., trigeminal, facial, ambiguus, and hypoglossal brainstem nuclei as well as ventral horn and motor cortex). Conversely, motoneuron groups that appear more resistant to the process of neurodegeneration in ALS (e.g., oculomotor, trochlear, and abducens nuclei) as well as the cerebellum receive only sparse 5-HT input. The glutamate excitotoxicity theory maintains that in ALS degeneration of motoneurons is caused by excessive glutamate neurotransmission, which is neurotoxic. Because of its facilitatory effects on glutaminergic motoneuron excitation, 5-HT may be pivotal to the pathogenesis and therapy of ALS. 5-HT levels as well as the concentrations 5-hydroxyindole acetic acid (5-HIAA), the major metabolite of 5-HT, are reduced in postmortem spinal cord tissue of ALS patients indicating decreased 5-HT release. Furthermore, cerebrospinal fluid levels of tryptophan, a precursor of 5-HT, are decreased in patients with ALS and plasma concentrations of tryptophan are also decreased with the lowest levels found in the most severely affected patients. In ALS progressive degeneration of 5-HT neurons would result in a compensatory increase in glutamate excitation of motoneurons. Additionally, because 5-HT, acting through presynaptic 5-HT1B receptors, inhibits glutamatergic synaptic transmission, lowered 5-HT activity would lead to increased synaptic glutamate release. Furthermore, 5-HT is a precursor of melatonin, which inhibits glutamate release and glutamate-induced neurotoxicity. Thus, progressive degeneration of 5-HT neurons affecting motoneuron activity constitutes the prime mover of the disease and its progression and treatment of ALS needs to be focused primarily on boosting 5-HT functions (e.g., pharmacologically via its precursors, reuptake inhibitors, selective 5-HT1A receptor agonists/5-HT2 receptor antagonists, and electrically through transcranial administration of AC pulsed picotesla electromagnetic fields) to prevent excessive glutamate activity in the motoneurons. In fact, 5HT1A and 5HT2 receptor agonists have been shown to prevent glutamate-induced neurotoxicity in primary cortical cell cultures and the 5-HT precursor 5-hydroxytryptophan (5-HTP) improved locomotor function and survival of transgenic SOD1 G93A mice, an animal model of ALS.

Abstract
BACKGROUND Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is the most common neurodegenerative disorder of the motor system in adults. Pain in ALS is a frequent symptom especially in the later stages of disease and can have a pronounced influence on quality of life and suffering. Treatment of pain therefore should be recognised as an important aspect of palliative care in ALS. OBJECTIVES To systematically review the evidence for the efficacy of drug therapy in relieving pain in ALS. We also aimed to evaluate possible adverse effects associated with the different drugs and their influence on survival and quality of life. SEARCH STRATEGY The authors searched the following databases: the Cochrane Neuromuscular Disease Group Trials Register (October 2007), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 1), MEDLINE (January 1966 to October 2007), EMBASE (January 1980 to October 2007), CINAHL (January 1982 to October 2007), AMED (January 1985 to October 2007) and LILACS (January 1982 to October 2007). We checked the bibliographies of trials identified and contacted other disease experts to identify further published and unpublished trials. SELECTION CRITERIA We searched for randomised or quasi-randomised controlled trials on drug therapy for pain in amyotrophic lateral sclerosis. DATA COLLECTION AND ANALYSIS Data were collected using a specially designed form and analysed using the Cochrane Review Manager software. MAIN RESULTS No randomised or quasi-randomised controlled trials on drug therapy for pain in ALS or MND were found. AUTHORS' CONCLUSIONS There is no evidence from randomised controlled trials about the management of pain in ALS. Further research on this important aspect of palliative care in ALS is needed. Randomised controlled trials should be initiated to determine the effectiveness of different analgesics for treatment of pain in ALS.

Abstract
OBJECTIVE: To establish correlations between nutritional, functional and respiratory indices of patients with amyotrophic lateral sclerosis (ALS). METHOD: Twenty patients (13 appendicular - GA and 7 bulbar - GB) were included in the multidisciplinary study at the Neurological Clinic Ambulatory of the University of Campinas Hospital. RESULTS: Among the GA type significant correlation was observed between maximal inspiratory (MIP) and expiratory (MEP) pressure (r= -0.76), MEP and pulse oxymetry (r=0.58), MIP and percent weight loss (%WL; r=0.59), and between MIP, total and subscale respiratory scores (ALSFRS-R) with %WL. With regard to the GB, correlation was found between MEP and body mass index (BMI) (r=0.97). In both GA and GB correlations were noticed between the BMI and the variables mass (kg), fat (%), arm and wrist circumference (cm), and tricipital, subscapular and supra-iliac skinfolds (mm), as well as the arm muscle circumference (cm) and fatty arm muscular area (mm²). CONCLUSION: It is suggested that the application of simple anthropometric measurements could be useful in routine monitoring of patients with ALS.

Abstract
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects the corticospinal tract. ALS functional rating scale (ALSFRS) is a questionnaire that quantifies motor deficits, while diffusion tensor imaging (DTI) evaluates the integrity of fibers through the fractional anisotropy (FA). In the present study, seven ALS patients were evaluated by ALSFRS and immediately submitted to DTI, getting FA values in the following regions: cerebral peduncle (PC), internal capsule (CI) and the white matter under the primary motor cortex (M1), secondary motor cortex (M2) and somesthetic cortex (SI). A control group was constituted by twelve healthy individuals. FA values in patients were significantly lower when compared with controls, with a tendency to higher reductions in the right hemisphere and more inferior regions. Interestingly, FA values were reduced in somesthetic area. No correlation was observed between symptoms duration and FA values. Despite the correlation observed between ALSFRS scores and degeneration in PC and CI, our results suggest that this subjective scale is not a good parameter for the evaluation of the structural damage in encephalic portions of the corticospinal tract.

Abstract
OBJECTIVE To study the clinical forms of amyotrophic lateral sclerosis (ALS) and the possible presence of risk factors in order to verify if there is any difference between cases in Paraná, Brazil. METHOD We studied 251 cases, all of which fulfilled the diagnosis criteria proposed in El Escorial (WFN). Between 1977 and 2004, 157 male and 94 female patients were examined. RESULTS 220 cases were classified as ALS-Spinal Onset (ALS-SO), 24 as ALS-Bulbar Onset (ALS-BO) and 7 as Familial ALS. The mean age at time of evaluation was 54.4+/-12.3 years, and symptoms had started 17.9+/-15.7 months previously. In the group studied, statistical relationships were found between heavy occupations and males; previous surgeries and females; ALS-BO and dysphagia and dysarthria in females; and ALS-SO and males, cramps, weakness, muscle atrophy, hypertonia, increased deep tendon reflex and abnormal gait. CONCLUSION The average age at time of evaluation was lower than that registered in the literature but similar to the Brazilian series. Domestic work and heavy occupations appear to be related to precocious perception of the symptoms by interference with daily functions. The socioeconomically higher classes seek medical care early. There was no relationship with exposure to toxic agents or trauma.

Abstract
There are few reports describing young-onset amyotrophic lateral sclerosis (ALS). Age at onset is a prognostic factor in ALS, and thus it is relevant to investigate the clinical features of very young ALS patients. We describe three young-onset ALS cases and review the literature. SOD1 mutations were not identified. Our cases and 24 others from the literature indicate that young-onset ALS is characterized by slowly progressive symmetrical weakness; nevertheless, progression is variable. Young-onset ALS seems to be a distinct clinical syndrome but its aetiological background is largely unknown.

Abstract
In this retrospective (1980-1998) study, we have analyzed clinico-demographically, from the records of the University Hospital of Fortaleza (Brazil), a group of 87 patients showing signs and symptoms of motor neuron diseases (MNDs). Their diagnosis was determined clinically and laboratorially. The WFN criteria were used for amyotrophic lateral sclerosis (ALS) diagnosis. The clinico-demographic analysis of the 87 cases of MNDs showed that 4 were diagnosed as spinal muscular atrophy (SMA), 5 cases as ALS subsets: 2 as progressive bulbar paralysis (PBP), 2 as progressive muscular atrophy (PMA) and 1 as monomelic amyotrophy (MA), and 78 cases of ALS. The latter comprised 51 males and 27 females, with a mean age of 42.02 years. They were sub-divided into 4 groups according to age: from 15 to 29 years (n= 17), 30 to 39 years (n= 18), 40 to 69 years (n= 39) and 70 to 78 years (n= 4). From the 78 ALS patients, 76 were of the classic sporadic form whilst only 2 were of the familial form. The analysis of the 87 patients with MNDs from the University Hospital of Fortaleza showed a predominance of ALS patients, with a high number of cases of juvenile and early onset adult sporadic ALS.

Abstract
OBJECTIVES To assess the epidemiologic characteristics of amyotrophic lateral sclerosis (ALS) in Brazil in 1998. METHOD Structured Clinical Report Forms (CRFs) sent to 2,505 Brazilian neurologists from January to September 1998 to be filled with demographic and clinical data regarding any ALS patient seen at any time during that year. RESULTS Five hundred and forty CRFs were returned by 168 neurologists. Data on 443 patients meeting the criteria of probable or definite ALS according to El Escorial definition were analysed: 63 probable (14.2%) and 380 definite (85. 8%). Two hundred and fifty-nine (58.5%) of the patients were male, mean age of onset was 52. Spinal onset occurred in 306 patients (69%); bulbar onset in 82 (18.5%), and both in 52 (11.7%). Twenty-six (5.9%) had a family history of ALS. Two hundred and fifty-nine (58.6%) were seen by private practitioners, and 178 (40. 2%) at a hospital clinic. Age-ajusted incidence shows a peak incidence at the 65-74 years old range. CONCLUSIONS The disease's characteristics are similar to those described in international studies, except for age of onset (Brazilian patients are younger). This difference is not confirmed when figures are age-adjusted.

Abstract
Objetivo: verificar se as informações dadas pela ABRELA permitem acesso aos recursos disponíveis (informativos, humanos, de suporte e material); se as expectativas foram atingidas e se há diferença de acesso aos recursos entre São Paulo (SP) e outros Estados. Método: 30 pacientes foram cadastrados na ABRELA (15 do estado de SP e 15 dos demais estados), com diagnóstico de esclerose lateral amiotrófica (ELA) confirmado há pelo menos um ano. Não foram avaliados pacientes com a forma de paralisia bulbar progressiva. Aplicou-se um questionário semi-estruturado com identificação pessoal, questões sobre a doença e, pertinentes ao acesso a recursos. Resultados: Eram 83,3% casados, 60% do sexo masculino e média de idade de 56,2 ± 2,180 anos. Mais da metade possui até dois cuidadores (63%), sendo o cônjuge o principal cuidador (31,6%). O suporte da comunidade está presente em 80% dos casos; porém 76,7% relatam a necessidade de outras assistências terap êuticas (hidroterapia, sede regional da ABRELA e atendimento domiciliar). Conclusões: apesar dos recursos estarem disponíveis, o acesso é maior por parte daqueles residentes no estado de SP, onde está localizada a sede da Associação. Justifica-se, assim, a necessidade de maiores investimentos para implantação de ABRELAs regionais bem como para formação e orientação de profissionais.
