Home ventilation has developed as a sufficient and safe method in many neurological diseases afflicting respiratory functions. To achieve an overview of the situation of these patients in Germany, a questionnaire was distributed by the manufacturer of the most commonly used ventilator in Germany. The patients were asked to send the form back, even anonymous, to the Department of Neurology, RWTH Aachen. 65 of 110 questionnaires were answered, most of patients with muscle dystrophy's (n = 14), Polio (n = 14) and spinal cord injuries (n = 11). Home ventilation in ALS was performed in 3 cases only. The majority of patients (n = 30) was aged between 20 and 49 years, but here were also 5 children younger than 10 years. Most patients were ventilated not more than 4 years, but there were also 5 patients ventilated for over 20 years, all of them Polio-patients. 70% of all lived at home with their relatives, who take care for them. Nevertheless, 13 were full- or part-time working.

To explore medical students' views of assisted death practices in patient cases that describe different degrees and types of physical and mental suffering, an anonymous survey was administered to all students at one medical school. Respondents were asked about the acceptability of assisted death activities in five patient vignettes and withdrawal of life support in a sixth vignette. In the vignettes, actions were performed by four possible agents: the medical student personally; a referral physician; physicians in general; or non-physicians. Of 306 medical students, 166 (54%) participated. Respondents expressed opposition or uncertainty about assisted death practices in the five patient cases that illustrated severe forms of suffering which were secondary to amyotrophic lateral sclerosis, treatment-resistant depressive and somatoform disorders, antisocial and sexually violent behavior, or AIDS. Students supported the withdrawal of life support in the sixth vignette depicting exceptional futility secondary to AIDS. Students were especially opposed to their own involvement and to the participation of non-physicians in assisted death activities. Differences in views related to sex, religious beliefs, and personal philosophy were found. Medical students do not embrace assisted death practices, although they exhibit tolerance regarding the choices of medical colleagues. How these attributes of medical students will translate into future behaviors toward patients and peers remains uncertain. Medical educators must strive to understand the perspectives of physicians-in-training. Expanded, empirically informed education that is attuned to the attitudes of medical students may be helpful in fulfilling the responsibility of imparting optimal clinical care skills.

Cannabis (marijuana) has been proposed as treatment for a widening spectrum of medical conditions and has many properties that may be applicable to the management of amyotrophic lateral sclerosis (ALS). This study is the first, anonymous survey of persons with ALS regarding the use of cannabis. There were 131 respondents, 13 of whom reported using cannabis in the last 12 months. Although the small number of people with ALS that reported using cannabis limits the interpretation of the survey findings, the results indicate that cannabis may be moderately effective at reducing symptoms of appetite loss, depression, pain, spasticity, and drooling. Cannabis was reported ineffective in reducing difficulties with speech and swallowing, and sexual dysfunction. The longest relief was reported for depression (approximately two to three hours).

This research examined the experience of Amyotrophic Lateral Sclerosis (ALS) patients who depend on an invasive mechanical ventilator in Japan. We investigated their difficulties in expressing their needs, their desires and wishes, and their sources of support and happiness. We examined the relationship between these factors and patient demographics, and hope as an indicator of successful adaptation to the illness experience (assessed by the Herth Hope Index). Interview results guided the formation of an anonymous questionnaire distributed to patients by mail. We interviewed 27 patients and their families and surveyed 157 respondents with a questionnaire. Most patients experienced multiple categories of difficulties, which correlated with reduced hope. More severe physical symptoms correlated with more emotional and social difficulties. Notable findings included a high prevalence of unalleviated pain, fear or experience of ventilator difficulties, and fear of burdening others. Having more sources of psychosocial support and happiness was associated with greater hope. Living at home was associated with fewer social difficulties. No patients claimed additional sources of support without claiming family or professional caregiver support, suggesting their mediation may be crucial in maintaining other social connections. Users of computer communication reported more sources of support and happiness and less frustration from difficulty expressing themselves. The most common reported desires, following a cure for ALS, related to the happiness of the patients' families, and a desire not to burden them. We also found that invasive mechanical ventilation (IMV) had been initiated emergently in 30.1% of patients without patient or family consent. Our results provide an insight into the world of this challenged population, elucidating the difficulties they face, and clarifying the role of support and other factors in maintaining hope. We identify concrete areas to which increased attention should be directed in patient care.

Amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD) and spinocerebellar degeneration (SCD) are included in the 45 intractable diseases" acknowledged by the Ministry of Health, Labour and Welfare of Japan. The registration of applicants is based on the attending doctors' diagnosis, and medical costs of registered patients are covered by the government. However, the accuracy of the diagnoses has not been investigated previously. The aim of the present study is to investigate the accuracy of the diagnoses of patients registered as PD, SCD and ALS in Mie prefecture of Japan. The study design was cross-sectional and the survey was carried out using an anonymous questionnaire. We asked the attending doctors the most probable clinical diagnosis in each applicant for PD, SCD or ALS at the annual renewal of application form of the specified diseases by the Ministry. The questionnaires were sent to the 57 neurologists in 20 general hospitals and 2 neurology clinics in Mie prefecture, Japan. The survey was carried out from July to September, 2003. For each disorder (PD, ALS, SCD), the accuracy rates were calculated as the ratio of the number of patients with the most probable diagnosis of the consistent disease to the number of all patients registered each disease. Questionnaires on 678 patients replied from 31 neurologists, 27 of whom were the neurology specialists approved by the Japanese Society of Neurology, were retrieved and analyzed. They covered 41.1% of the total registered PD cases, 45.4% of total SCD cases, and 54.0% of total ALS cases in Mie prefecture. The final clinical diagnosis were made by such specialists in 641 cases (94.5%). The accuracy rate of PD was 97.3% for all degenerative parkinsonisms and 90.2% for idiopathic PD, 96.0% for SCD, and 77.8% for typical ALS and 81.5% for ALS and Kennedy-Alter-Sung syndrome. Although the most probable diagnoses were performed by the attending physicians without verification by other raters, the accuracy rates were excellently high in these diseases, partly because most of the attending physicians were neurology specialists. The relatively low accuracy rate in ALS may be caused partly by the difficulty in differentiating it from spine diseases, neuropathies or myopathies at the early stage of the disease when the patients had been registered, or by inclusion of other motor neuron diseases such as Kennedy-Alter-Sung syndrome.

In March 2009 we sent out the questionnaire to the 4,478 board certified neurologist to ask about the palliative care in ALS. 1,495 anonymous responses (33%) have been returned. 21% of the respondents prescribe morphine, which shows a drastic increase from the 14% in the 2007 survey. However, 77% of them had only less than 5 patients, 47% of them studied and trained themselves. It illustrates that most of the neurologists are not well experienced with morphine, and that they are isolated in practice. However, 47% of the respondents answer that they would prescribe morphine whether or not the national insurance pays. As for the withdrawal of the permanent ventilation, 21% of the respondents were asked by their patients to turn off the ventilation. While 24% of the respondents believe that the withdrawal right not should be promoted, 46% believe that such right should be granted if the decision made by the patient and/or his/her family members can explicitly be recognized. The result illustrates that the physicians are also divided. It may be the time to lay the foundation for the Japanese ALS physicians to discuss openly and candidly together to deal with the wants and wishes of their patients.

Brain-machine interfaces (BMIs) may provide new communication channels and motor function to individuals with severe neurodegenerative diseases, but little is known about their interests in such devices. We investigated the interests of severely affected ALS patients in BMIs, and examined factors that might influence these interests. We conducted an anonymous, mail-back questionnaire survey of severely disabled ALS patients diagnosed using the revised El Escorial criteria. Thirty-seven patients responded to the questionnaire. Twenty-nine (78.4%) had undergone tracheostomy positive pressure ventilation. More than 80% of the patients were interested in communication support. Thirty-three (89.2%) felt stressed during communication. Among those using assistive communication devices (17 patients), 15 (88.2%) were not satisfied with them. More than 50% of the patients expressed an interest in BMIs. Their expectations of BMIs ranged widely from emergency alarm to postural change. The frequent use of personal computers tended to be correlated with an interest in invasive BMIs (p = 0.07). In conclusion, this was the first questionnaire survey demonstrating that severely affected ALS patients have broad and high expectations for BMIs. Communication was the most desired support from BMIs for such patients. We need to meet their widely ranging expectations of BMIs.

The objective of this study was to describe muscle cramps in an US sample of amyotrophic lateral sclerosis (ALS) patients. Utilizing an anonymous web based questionnaire we queried ALS patients regarding the severity, frequency, time-course, treatment of muscle cramps and their relationship to pain. The survey had 282 respondents with 92% reporting that they had cramps. For 20% of the sample, cramps were stated to be the presenting ALS symptom. Cramp severity was rated at a mean of 5.2/10 and the mean cramp frequency was 5.3 cramps per day. Cramp intensity and frequency did not correlate with duration or severity of ALS. Pain as measured with the Patient Reported Outcome Measurement Information System (PROMIS) pain scales was not statistically different from the US general population. Cramp severity and frequency significantly and positively correlated with the PROMIS pain scales. Patients with more severe cramps were more likely to use prescription medications for their cramps compared to patients with milder symptoms. Treatments directed at cramps were tried by 57%. In conclusion, cramps are a common symptom in ALS and it does not correlate with disease duration or severity. The severity of cramps is on average moderate and many patients try treatments.

Despite the fatal outcome and progressive loss of physical functioning in amyotrophic lateral sclerosis (ALS), many patients maintain contentment in life. It has been shown that non-professionals tend to underestimate the well-being of patients with ALS, but professionals' perspective is yet to be studied. In total, 105 neurologists with varying degrees of experience with ALS were included in an anonymous survey. They were asked to estimate the quality of life and depressiveness of ALS patients with artificial ventilation and nutrition. Physicians' estimations were compared with previously reported subjective ratings of ALS patients with life-prolonging measures. Neurologists with significant experience on ALS and palliative care were able to accurately estimate depressiveness and quality of life of ALS patients with life-prolonging measures. Less experienced neurologists' estimation differed more from patients' reports. Of all life-prolonging measures neurologists regarded invasive ventilation as the measure associated with lowest quality of life and highest depressiveness of the patients. Experienced neurologists as well as neurologists with experience in palliative care are able to better empathize with patients with a fatal illness such as ALS and support important decision processes.

Psychological stress has been suggested to be relevant to the pathogenesis of neurodegenerative disorders, possibly via the generation of oxygen free radicals. We therefore sought to determine whether people with amyotrophic lateral sclerosis (ALS) had been subjected to more potentially stressful life events or occupations than controls, and whether they had differences in resilience or trait anxiety that would moderate their responses to these stressors. An online anonymous multilingual questionnaire was used to collect data on significant life events from people with and without ALS, using items from a modified Social Readjustment Rating Scale and from self-described significant events, which were combined to create a Life Events Inventory. Inventory scores were subdivided into 0-20 years and 21-40 years age ranges, and for the preceding 2, 5 and 10 years. Respondents also rated levels of stress experienced during different occupations. Resilience was measured using the Connor-Davidson Resilience Scale, and trait anxiety with a modified Geriatric Anxiety Inventory. Scores were compared using nonparametric statistics. Data from 400 ALS (251 male, 149 female) and 450 control (130 male, 320 female) respondents aged 40 years and over showed that Life Events Inventory scores were similar in male ALS respondents and controls, but lower in female ALS respondents than female controls for the preceding 5-year and 10-year periods. Occupational stress did not differ between ALS respondents and controls. Both male and female ALS respondents had higher resilience scores than controls. Anxiety scores did not differ between ALS and control groups. In conclusion, people with ALS reported no raised levels of potentially stressful premorbid life events or occupational stress, and did not have reduced levels of resilience, or increased levels of anxiety, that would augment the deleterious effects of stressors. On the contrary, ALS respondents had higher resilience than controls, though this conclusion relies on ALS respondents recalling their premorbid status. These results do not support the hypothesis that psychological stress from significant life events or occupational stress plays a role in the pathogenesis of ALS.
