- It may seem useless to propose preventive measures for a disease without established pathogenesis and successful therapy, such as amyotrophic lateral sclerosis (ALS). However, we will show that ALS shares essential molecular mechanisms with aging and that established anti-aging strategies, such as healthy diet or individually adjusted exercise, may be successfully applied to ameliorate the condition of ALS patients. These strategies might be applied for prevention if persons at ALS risk could be identified early enough. Recent research advances indicate that this may happen soon.

- Objective: To define an applicable dataset for ALS patient registries we weighted specific clinical items as scored by worldwide ALS experts.Methods: Sixty participants were invited based on relevant clinical work, publications and personal acquaintance. They rated 160 clinical items consensually agreed by the members of our project, incorporating specialists from five European Centres. Scoring scheme was defined as: 1 - essential; 2 - important; 3 - not very important. A mixed effect model was applied to rank items and to find possible correlations with geographical region (Europe vs. outside Europe).Results: We received 40 responses, 20 from Europe and 20 from outside; 42/160 data were scored as essential by >50% of the respondents, including: date of birth, gender, date of disease onset, date of diagnosis, ethnicity, region of onset, predominant upper neuron (UMN) or lower motor neuron (LMN) impairment, proximal versus distal weakness, respiratory symptoms, dysarthria, weight loss, signs of LMN/UMN involvement, emotional incontinence, cognitive changes, respiratory signs, neck weakness, body mass index, ALSFRS-R at entry, ALSFRS-R subscores at entry, timing and pattern of spreading and staging, electromyography, spirometry, MRI, CK level, riluzole intake, genetic background, history of physical exercise and previous and current main occupation. Four components were scored as non-relevant, including place of birth, blood pressure and pain at onset. There was no significant difference between regions (European vs. non-European countries).Conclusions: Our study identified a consensual set of clinical data with 42 specific items that can be used as a minimal data set for patient registers and for clinical trials.

- Introduction: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with loss of muscle function. The pathogenesis is still unclear and the heterogeneity of ALS phenotypes is huge. We investigated a large population of ALS patients and controls concerning comorbidities and medications to detect specific risk or protective factors regarding onset and progression of ALS.Methods: We investigated a cohort of 200 ALS patients pro- and retrospectively compared to a control group. For comparison of frequencies of comorbidities and medication intake, uni- and multivariate binary logistic regressions were performed. To analyze the influence of comorbidities and medication on the progression of ALS, we used linear regression analysis.Results: ALS patients showed a relevantly higher prevalence of strokes and depression compared to controls. Moreover, ALS patients reported relevantly more often regular physical activity and their BMI was lower. The coexistence of coronary heart disease was associated with a relevantly faster disease progression. Intake of contraceptives was relevantly higher in controls compared with ALS patients.Conclusions: Our results suggest stroke, lower BMI, and regular physical activity as risk factors for ALS. Strokes could be a possible trigger of the pathogenetic pathway of ALS and the lower BMI with consecutively lower rate of hyperlipidemia supports the hypothesis of premorbid hypermetabolism in ALS patients. Coexistence of coronary heart disease possibly has a negative influence on respiratory involvement. Contraceptives could be beneficial due to a protective effect of estrogen. Information on influencing factors can help to elucidate the pathogenesis of ALS or provide approaches for possible therapeutic options.

- Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease mainly affecting upper and lower motor neurons in the brain and spinal cord. Pathogenesis of ALS is still unclear, and a multifactorial etiology is presumed. The remarkable clinical heterogeneity between different phenotypes of ALS patients suggests that environmental and lifestyle factors could play a role in onset and progression of ALS. We analyzed a cohort of 117 ALS patients and 93 controls. ALS patients and controls were compared regarding physical activity, dietary habits, smoking, residential environment, potentially toxic environmental factors and profession before symptom onset and throughout the disease course. Data were collected by a personal interview. For statistical analysis descriptive statistics, statistical tests and analysis of variance were used. ALS patients and controls did not differ regarding smoking, diet and extent of physical training. No higher frequency of toxic influences could be detected in the ALS group. ALS patients lived in rural environment considerably more often than the control persons, but this was not associated with a higher percentage of occupation in agriculture. There was also a higher percentage of university graduates in the ALS group. Patients with bulbar onset were considerably more often born in an urban environment as compared to spinal onset. Apart from education and environment, ALS phenotypes did not differ in any investigated environmental or life-style factor. The rate of disease progression was not influenced by any of the investigated environmental and life-style factors. The present study could not identify any dietary habit, smoking, physical activity, occupational factor as well as toxic influences as risk factor or protective factor for onset or progression of ALS. Living in rural environment and higher education might be associated with higher incidence of ALS.
