- Self-reported cognitive symptoms are frequent in persons with amalgam-related complaints, but few studies have focused on their cognitive function. The aim was to examine a symptom profile and whether participants with amalgam-related complaints have cognitive deficits in comparison with control individuals. We drew 342 participants with amalgam-related complaints and 342 one-to-one matched control individuals from a longitudinal population-based study. For 81 of the participants with amalgam-related complaints and controls, data were available approximately five years before the onset of complaints, making a longitudinal analysis possible. All participants were assessed by a self-reported health questionnaire and a comprehensive cognitive test battery. The participants with amalgam-related complaints reported more symptoms, mainly musculoskeletal and neuropsychological, compared with control individuals (p < 0.001). The results revealed no significant difference between the amalgam and control group, either cross-sectionally or longitudinally, for any of the cognitive tests. These results suggest that cognitive decline is not associated with amalgam-related complaints.

- Objectives: The role of stressful life events in the onset of self-reported amalgam-related complaints is unclear. The aim of this study was to examine the relationship between life events and amalgam-related complaints. Method: The participants were selected from a longitudinal population-based study. One-to-one matching of 337 participants with amalgam-related complaints to 337 participants without such complaints was performed. For 81 of the participants with amalgam-related complaints and their matched controls, data was also available approximately 5 years before the onset of complaints, making longitudinal analysis possible. All participants completed questionnaires assessing the occurrence of 55 life events. Results: The results showed that many participants with amalgam-related complaints experienced negative life events before and at the onset of amalgam-related complaints. They also reported more unexpected and uncontrollable events difficult to adjust to in comparison with controls. The groups did not differ on positive or neutral life events. Somatic illness or surgical operation was the most common life event. Death of a very close family member and a major change in financial situation were also commonly reported. Conclusions: This study indicates that adverse negative life events could play a vital role in understanding and explaining amalgam-related complaints.
