In the Project on Death in America ALS cohort, 121 patients were followed to examine the timing of key milestones in the course of the disease, such as tracheostomy and PEG placement. During the 2- to 4-year follow-up period, 26.5% of patients received PEG, yielding a cumulative incidence of 48%. PEG placement occurred, on average, 16 months after patients received confirmation of the diagnosis at our Center. Patients who received PEG were more likely to have tracheostomies than patients not using PEG (p<0.01). In multivariate proportional hazard models that included both sociodemographic and disease indicators, the strongest predictor of PEG use was a patient's baseline preference for PEG: 57.1% of patients "absolutely in favor" went on to have PEG, compared to only 9.3% of those "absolutely against" (p<0.01). PEG users were more likely to have initiated health care proxies. These findings suggest that patients who use PEG may be consistently proactive in the face of the disease. 相似文献

Considering the few studies published on the psychopathology of ALS patients, we carried out a preliminary study evaluating depression, anxiety, emotional reactions and coping strategies in such patients. Twenty-seven ALS patients were included and evaluated using a semi-structured interview, after which they were asked to complete a questionnaire. The rater asessed the DSM-IV criteria for a major depressive episode, dysthymia and generalized anxiety, using the MADRS scale for depression, the Covi anxiety scale and the Depressive Mood scale. Subsequently, patients completed the Ways of Coping checklist. Patients were neither anxious nor depressed. Patients whose diagnosis was recent (less than six months) presented greater emotional deficit. Patients younger than 50 years of age used problem focused strategies more frequently. Those having received the diagnosis in the preceeding six months used emotion focused strategies significantly more often.The absence of characterized depression and anxiety confirmed results of the literature. The significance of this study is found in the observation of specific emotional reactions present in the first six months following diagnosis disclosure. The results show that it is useful to continue the affective evaluation of these patients and to undertake longitudinal studies starting at the time of diagnosis disclosure. 相似文献

A prospective study of cognitive impairment in ALS 总被引:9,自引:0,他引:9
OBJECTIVE: To characterize prospectively the cognitive profile in ALS. METHODS: Clinically definite ALS patients (11 men, 2 women), age 39.9 to 74.0 years (mean age, 54.2 +/- 9.6 years; mean disease duration, 21.1 +/- 10.5 months) underwent neuropsychologic, language, and speech testing followed by MR 1H spectroscopy (4 T). Five spousal control subjects completed an identical protocol. Eight ALS patients participated in follow-up studies at a 6-month interval. RESULTS: Relative to control subjects, ALS patients showed mild impairment in word generation, recognition memory (faces), and motor-free visual perception. Bulbar-onset patients showed greater impairment in a number of measures (working memory, problem solving/cognitive flexibility, visual perception, and recognition memory for words and faces), and cognitive impairment appeared more progressive over time. ALS patients demonstrated anomia on a confrontation naming test, with no significant problems following commands or repeating. Speech motor performance scores and intelligibility scores were not significantly different. No significant declines in forced vital capacity, forced expiratory volume, or peak expiratory flow rates were observed. Although normal at initial testing (T1), MR 1H spectroscopy demonstrated a reduction of the N-acetylaspartate/creatine (NAA/Cr) ratio in the nondominant precentral motor strip across the two testing intervals. In contrast, the NAA/Cr ratio obtained from the anterior cingulate gyrus at T1 was already reduced in bulbar-onset patients (p < 0.001), whereas no deficits were observed in limb-onset individuals in the same region. CONCLUSIONS: Bulbar-onset ALS patients with cognitive impairments and neuronal loss in the anterior cingulate gyrus subsequently developed more profound neuropsychological dysfunction whereas both language and speech capabilities remained relatively preserved. Of note, the absence of bulbar signs did not predict an absence of cognitive decline. 相似文献

Noninvasive positive pressure ventilation prolongs survival in ALS but its effect on quality of life is unknown. The authors prospectively studied quality of life using the SF-36 questionnaire in a cohort of 16 ventilated patients with ALS. Noninvasive positive pressure ventilation improved scores in the "Vitality" domain by as much as 25%, for periods of up to 15 months, despite disease progression. Noninvasive positive pressure ventilation did not cause reduced quality of life, as any fall in scores in the ventilated group were comparable to those seen in a control group. In conclusion, noninvasive positive pressure ventilation enhances quality of life when used to treat sleep-disordered breathing in patients with ALS. 相似文献

OBJECTIVE: To determine whether ALS patients' preferences for ameliorative or life-extending technologies elicited early in the disease were related to later treatment choices. METHODS: In this prospective cohort study, 121 patients were seen at a tertiary ALS care center and followed for a median of 12 months. At baseline, patient preferences for use of tracheostomy and percutaneous endoscopic gastrostomy (PEG) placement were elicited. All patients received the same educational information before being interviewed about treatment preferences. Patients were then followed to determine if patients who viewed the interventions favorably at baseline were significantly more likely to use the interventions over follow-up. RESULTS: Six to twelve percent of patients were certain they wanted tracheostomy and 28.2% wanted PEG. Preferences were related to later treatment choices: 20% of patients who found tracheostomy acceptable had one in the follow-up period, compared with 3.4% of those not in favor (p < 0.001). For PEG, similar findings were obtained: 48.5% who initially found it acceptable had PEG, versus 8.1% of those not in favor of this treatment (p < 0.001). Patients who found the interventions acceptable were more likely to be recently diagnosed, expressed greater attachment to life, and showed greater declines in pulmonary function over follow-up. CONCLUSIONS: Patients with ALS were able to express their preferences for life-extending or ameliorative technologies and made choices consistent with these preferences. However, patient preferences may change over time, and clinical education efforts are required throughout the course of disease. 相似文献

Bipap improves survival and rate of pulmonary function decline in patients with ALS. 总被引:9,自引:0,他引:9

Amyotrophic Lateral Sclerosis (ALS) is a progressive motor neuron disease that frequently causes death within five years of diagnosis. The majority of deaths are due to pulmonary complications resulting from respiratory muscle weakness and bulbar involvement. A promising respiratory intervention is the recently introduced bi-level intermittent positive pressure (Bipap), which is a noninvasive ventilator modality shown to reduce the work of breathing and improve not only gas exchange, but also exercise tolerance and sleep quality. The aim of this study was to assess the utility of Bipap in prolonging survival in ALS. We retrospectively analyzed the results of Bipap use in 122 patients followed at Hahnemann University. All patients in this study were offered Bipap when their forced vital capacity (FVC) dropped below 50% of predicted value. Group 1 (n=38) accepted Bipap and used it more than 4 h/day. Group 2 (n=32) did not tolerate Bipap well and used it less than 4 h/day. Group 3 (n=52) refused to try Bipap. There was a statistically significant improvement in survival from initiation of Bipap in Group 1 (14.2 months) compared to Group 2 (7.0 months, P=0.002) or 3 (4.6 months, P<0.001) respectively. Furthermore, when the slope of vital capacity decline was examined, the group that used Bipap more than 4 h/day had slower decline in vital capacity (-3.5% change/month) compared to Group 2 (-5.9% change/month, P=0.02) and Group 3 (-8.3% change/month, P<0.001). We conclude that Bipap can significantly prolong survival and slow the decline of FVC in ALS. Our results suggest that all patients with ALS be offered Bipap when their FVC drops below 50%, at the onset of dyspnea, or when a rapid drop in %FVC is noted. 相似文献

The dynactin p150glued subunit, encoded by the gene DCTN1 is part of the dynein–dynactin motor protein complex responsible for retrograde axonal transport. This subunit is a candidate modifier for neurodegenerative diseases, in particular motoneuron and extrapyramidal diseases. Based on an extensive screening effort of all 32 exons in more than 2,500 ALS/MND patients, patients suffering from Parkinsonian Syndromes and controls, we investigated 24 sequence variants of p150 in cell-based studies. We used both non-neuronal cell lines and primary rodent spinal motoneurons and report on cell biological abnormalities in five of these sequence alterations and also briefly report on the clinical features. Our results suggest the presence of biological changes caused by some p150 mutants pointing to a potential pathogenetic significance as modifier of the phenotype of the human disease. 相似文献

OBJECTIVE: To evaluate sensory nerve conduction studies in ALS in a prospective multicentre study involving 7 neurophysiologists from 6 European countries. METHODS: Bilateral sural potentials were obtained in 35 ALS patients and 35 age-matched controls according to a standardised examination protocol using antidromic surface technique. The recordings from the right sural nerve of the controls were used for reference values. A reduction from the mean of controls greater than 2 SDs was considered abnormal. RESULTS: Reduced sensory nerve action potential (SNAP) amplitude or reduced conduction velocity (CV), or both, was found in 6 ALS patients (17%). Decrease in CV was the most frequent finding, and was observed in 8 nerves from 5 patients. Reduced SNAP amplitude was found in 2 nerves from 2 patients. All changes were minor ranging from -2.1 to -3.2 SDs. CONCLUSIONS: This is the first standardised multicentre study on sensory potentials in ALS. It confirms that although normal sensory findings should be expected in the majority of ALS patients, minor abnormalities are not uncommon. SIGNIFICANCE: Mild sensory abnormalities do not necessarily exclude a diagnosis of ALS. 相似文献

Needle electromyography (EMG) of the tongue is difficult to perform because of frequent uncontrollable movement. We chose the sternocleidomastoid (SCM) muscle as a possible alternative for assessing the involvement of the rostral neuraxis in amyotrophic lateral sclerosis (ALS). We prospectively studied 21 ALS patients during our initial diagnostic evaluation. EMG parameters that we recorded included the presence of abnormal spontaneous activity, pattern of motor unit potential recruitment, and configuration of motor unit action potentials. For the six patients with bulbar-onset ALS, three had abnormalities in the SCM and three had abnormalities in the tongue. In contrast, for the 15 patients with limb-onset ALS, 9 had abnormalities in the SCM, and only 3 had abnormalities in the tongue. Our results demonstrate the utility of needle EMG of the SCM in the evaluation of ALS. EMG of the SCM carries a similar sensitivity as the tongue in ALS patients with bulbar symptoms, but is more sensitive than the tongue in patients without bulbar symptoms. SCM innervation includes the rostral cervical cord and brainstem, and EMG abnormalities in this muscle support a diffuse involvement, which is unique to ALS. 相似文献

Although there is good evidence that emotions are associated with chronic airways obstruction, evidence for the influence
of psychological factors on the level and decline of pulmonary function is sparse. Optimism has been linked to enhanced well-being,
whereas pessimism has been identified as a risk factor for poor physical health. This investigation examines prospectively
the effects of optimism versus pessimism on pulmonary function. Data are from the Veterans Administration Normative Aging
Study, an ongoing cohort of older men. In 1986, 670 men completed the revised Minnesota Multiphasic Personality Inventory
from which we derived the bipolar Revised Optimism-Pessimism Scale. During an average of 8 years of follow-up, an average
of 3 pulmonary function exams were obtained. Men with a more optimistic explanatory style had significantly higher levels
of forced expiratory volume in 1 sec (FEV1) and forced vital capacity (both p > .01). Interactions between time and optimism
suggested that rate of decline in FEV1 over time was slower in men with a more optimistic explanatory style relative to men
who were more pessimistic. These data are the first to link optimism with higher levels of pulmonary function and slower rate
of pulmonary function decline in older men, a protective effect that is independent of smoking.

Eighty-two women with complaints of moderate to severe premenstrual symptoms were recruited for a double-blind, controlled trial of a triphasic oral contraceptive (o.c.). Subjects made daily ratings of symptoms for at least one baseline cycle and were then randomly assigned to receive either placebo or o.c. for three months. Twenty-three women dropped out of the study (18 o.c., 5 placebo), 13 failed to show prospective confirmation of moderate to severe premenstrual symptoms, and one placebo subject had an anovulatory cycle. Forty-five women with prospectively-confirmed premenstrual changes (20 o.c., 25 placebo) completed the study. Premenstrual breast pain and bloating were significantly reduced with active treatment compared to placebo (p less than 0.03) but there were no beneficial effects of the o.c. over placebo for any of the mood symptoms. Women who received o.c.s reported decreased sexual interest after starting treatment and this effect was independent of any adverse influence on mood. 相似文献

This pilot study aimed at exploring the effects of intrathecally administered brain derived neurotrophic factor (BDNF) on autonomic functions in patients with ALS. A battery of autonomic sympathetic and parasympathetic tests was performed at baseline and after nine months of treatment in 10 ALS patients participating in a double-blind placebo-controlled phase II/III study of intrathecally administered BDNF. Results of patients treated with BDNF (25 or 150 microg/day) were compared to those receiving placebo. Sudomotor function and blood pressure response to handgrip significantly worsened during the treatment period (55.4+/-26.1 vs. 38.9+/-23.9 g/m(2)h, p<0.05; 20+/-6 vs. 13+/-4 microHg, p<0.05) whereas other sympathetic and all parasympathetic function tests only tended to be more abnormal at follow-up. Serum norepinephrine levels increased significantly during the nine-months observation period. The results of autonomic function tests were not different between patients treated with BDNF and placebo, but norepinephrine levels were higher in the BDNF group. We conclude that autonomic nervous system function deteriorates along with poorer motor performance independently from treatment with BDNF. The elevation of norepinephrine levels might reflect a non-specific up-regulation, and its association with BDNF an autocrine effect. 相似文献

We developed a new ALS scale which is characterized by inclusion of as many check items as 77 which range from cranial nerve region to extremities and trunk. Despite of large number of items, it is neither time-consuming, nor poses much burden on patients or examiners as the activity tests are so devised and most of them can be done while the patient remains in supine position. In addition, an attempt is made that the total score obtained by the scale reflects not only the degree of disability of the patients but also the extent of motor neuron loss. Using the scale, ALS progression was prospectively studied in 13 patients and it was found that in older patients ALS progresses more rapidly than in younger patients. 相似文献

OBJECTIVE: The authors report results from a 7-year prospective study of depression and mortality in 2,558 Medicare recipients age 65 and older. METHODS: This report is based on a secondary data analysis of a randomized controlled trial that evaluated the cost-effectiveness of preventive services for older enrollees in an HMO. RESULTS: Subjects with mild-to-moderate depression at baseline did not have an increased risk of mortality compared with those without significant depression. The 3% of older adults with the most severe depressive syndromes, however, had significant increases in mortality, even after adjusting for demographics, health risk behaviors, and chronic medical disorders. CONCLUSION: The increase in mortality in this group of older adults was comparable to that in participants with chronic medical disorders such as emphysema or heart disease. 相似文献

Thirty healthy young women volunteered to complete questionnaires concerning physical and psychological symptoms during a full menstrual cycle. A maximal incidence of minor physical and psychological symptoms was observed in the first few days of menstruation. This was preceded by a gradual rise in the level of symptomatology during the premenstruum. 相似文献

The authors prospectively examined the prevalence of somatization symptoms among community respondents after a natural disaster in Puerto Rico. Exposure to the disaster was related to a higher prevalence of medically unexplained physical symptoms, particularly gastrointestinal ones (abdominal pain, vomiting, nausea, excessive gas) and pseudoneurological ones (amnesia, paralysis, fainting, unusual spells/double vision). 相似文献
