| Summary | Psychological stress has been suggested to be relevant to the development of neurodegenerative disorders. This study sought to determine whether people with ALS have been subjected to more potentially stressful life events or occupations than others, and whether they had differences in resilience or trait anxiety that would affect their responses to these stressors. PALS reported no raised levels of potentially stressful premorbid life events or occupational stress, did not have reduced levels of resilience, or increased levels of anxiety. 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. |
