  • APOE influences on neurosychological function after mild head injury : within-person comparisons
  • 2004
  • Ingår i: Neurology. - Minneapolis, Minn : Lancet Publications Inc.. - 0028-3878 .- 1526-632X. ; 62:11, s. 1963-1966

    • Objective: To examine the relationship between neuropsychological outcome following mild head injury (MHI) and APOE genotype. Methods: Data from a population-based longitudinal study (n = 3,500) were used to identify 34 adults who experienced MHI during the course of the study. Their pre- and postinjury performances on a battery of nine neuropsychological tests were compared within person, and the postinjury performance was compared with that of age- and gender-matched control subjects. Results: The within-person comparisons showed that participants with at least oneAPOE ε4 allele (n = 11) had a significantly decreased postinjury performance on three of the tests, whereas the postinjury performance for APOE ε4-negative participants (n = 23) was unchanged. There was no significant difference in postinjury performance between participants with/without the ε4 allele, and neither group was impaired relative to controls. Conclusions: APOE genotype may influence the outcome following an MHI. Pre/postinjury within-person comparisons seem more sensitive than control group comparisons for detecting injury-related effects.

  • Cognitive Status in Persons with Amalgam-related Complaints
  • 2010
  • Ingår i: Journal of Dental Research. - : SAGE Publications. - 0022-0345 .- 1544-0591. ; 89:11, s. 1236-1240
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Fatigue before and after mild traumatic brain injury: Pre- and post-comparisons in relation to ApolipoproteinE
  • 2007
  • Ingår i: Brain Injury. - London : Informa UK Limited. - 0269-9052 .- 1362-301X. ; 21:10, s. 1049-1054
  • Tidskriftsartikel (refereegranskat)abstract
    • Primary objective: To assess the incidence of fatigue for persons following a mild traumatic brain injury (MTBI) and to evaluate the relationship between fatigue and APOE genotype. As fatigue is often found to be influenced by anxiety, depression and sleep disturbance, these factors were also measured. Methods and procedures: Thirty-one persons who sustained a MTBI were drawn from a population-based longitudinal study. Each person who sustained a MTBI was matched by age, gender, education and APOE genotype with two non-head injury controls. Self-reported pre- and post-injury incidence of fatigue, anxiety, depression and sleep disturbance was compared within-group and between groups. Results: For the MTBI group, incidence of fatigue was almost twice as common post- than pre-injury, whereas there was no corresponding change in a non-injured control group. Within the MTBI-group, post-injury fatigue was particularly common for carriers of the APOE ε4 allele. Conclusions: Fatigue is common sequela after a MTBI and especially pronounced for carriers of the APOE ε4 allele.

  • Increased risk of dementia following mild head injury for carriers but not for non-carriers of the APOE ε4 allele.
  • 2007
  • Ingår i: International Psychgeriatrics. ; 19
  • Tidskriftsartikel (populärvet., debatt m.m.)abstract
    • Background: The є4-allele of Apolipoprotein-E (APOE) and head injury are risk factors for dementia diseases, and these factors may act synergistically to further increase the risk. The aim of the present study was to examine the association between mild head injury, APOE, and dementia.Methods: Data were obtained from the Betula prospective population-based study of aging, memory, and health. The study included 543 participants in the age range 40-85 years, free of dementia at baseline, who were followed-up within a 5-year interval. Dementia was classified using the Diagnostic and Statistical Manual of Mental Disorders Criteria. Information of previous head injury was done through screening of the participants’ answers to health questionnaires both at baseline and at following test occasions.Results: We found that subjects with head injury but without APOE є4 had no increased risk of dementia. Subjects with APOE є4 had elevated risk and those with both APOE є4 and head injury had the highest risk (OR = 5.2).Conclusions: This study confirms that APOE ε4 constitutes a risk factor of dementia, that mild injury in isolation does not increase the risk, but that head injury in combination with the APOE ε4 lead to increased risk of dementia.

    • Background: The ε4 allele of apolipoprotein E (APOE) and head injury are risk factors for dementia diseases, and may act synergistically to further increase the risk. The aim of this study was to examine the association between mild head injury, APOE and dementia.Methods: Data were obtained from the Betula prospective population-based study of aging, memory, and health. The study included 543 participants in the age range 40–85 years, free of dementia at baseline, who were followed up within a 5-year interval. Dementia was classified using DSM-IV criteria. Information on previous head injury was obtained through screening of the participants' answers to health questionnaires at baseline and at follow-up.Results: Subjects with head injury but without APOE ε4 had no increased risk of dementia. Subjects with APOE ε4 had an increased risk and those with both APOE ε4 and head injury had the highest risk of dementia (odds ratio = 5.2).Conclusions: APOE ε4 constitutes a risk factor for dementia, mild injury in isolation does not increase the risk, but head injury in combination with the APOE ε4 leads to increased risk of dementia.

  • Stressful negative life events and amalgam-related complaints
  • 2011
  • Ingår i: Community Dentistry and Oral Epidemiology. - : Wiley. - 0301-5661 .- 1600-0528. ; 39:1, s. 12-18
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Effects of perceived long-term stress on health and memory functioning
  • 2010
  • Ingår i: Abstracts of the Psychonomic Society. ; , s. 78-78
  • Konferensbidrag (refereegranskat)abstract
    • The study examined effects of perceived long-term stress on health and memory functioning in middle-aged individuals (40–60 years). Participants in the Betula study (Nilsson et al., 1997) describing themselves as being stressed in general over three measurement occasions (10 years in total) were compared with a matched (sex and education) group (n = 98) reporting no stress. The results revealed a higher incidence of depressive symptoms, flus, and not-healthy-ratings over time for the stress group. In addition, the stress group provided more negative subjective memory ratings, whereas time-related change in memory performance, indicative of a high degree of cognitive stability, did not differ from that of controls. Degree of perceived stress is discussed as a factor underlying variations in regard to the outcome of studies of perceived stress.
