  • Applying polygenic risk scoring for psychiatric disorders to a large family with bipolar disorder and major depressive disorder
  • 2018

    • Psychiatric disorders are thought to have a complex genetic pathology consisting of interplay of common and rare variation. Traditionally, pedigrees are used to shed light on the latter only, while here we discuss the application of polygenic risk scores to also highlight patterns of common genetic risk. We analyze polygenic risk scores for psychiatric disorders in a large pedigree (n ~ 260) in which 30% of family members suffer from major depressive disorder or bipolar disorder. Studying patterns of assortative mating and anticipation, it appears increased polygenic risk is contributed by affected individuals who married into the family, resulting in an increasing genetic risk over generations. This may explain the observation of anticipation in mood disorders, whereby onset is earlier and the severity increases over the generations of a family. Joint analyses of rare and common variation may be a powerful way to understand the familial genetics of psychiatric disorders.

  • Anxiety Disorders are Associated with Low Socioeconomic Status in Women but Not in Men
  • 2017
  • Ingår i: Women's health issues. - 1049-3867 .- 1878-4321. ; 27:3, s. 302-307

    • Objectives: We investigated to what extent the lifetime prevalence of anxiety disorders relates to negative economic changes, taking important lifestyle factors and unexpected life events into consideration. Methods: We included 3,695 participants recruited in the city of Lausanne (Switzerland), from the population-based CoLaus/PsyCoLaus study. The association between anxiety disorders, lifestyle factors, and life events related to income was investigated using binary logistic regression analyses correcting for demographic and clinical confounders. Results: Compared with men, women with anxiety disorders showed a significantly lower socioeconomic status (Mann-Whitney U = 56,318; p < .001) and reported a higher negative impact of substantial reduction of income (Mann-Whitney U = 68,531; p = .024). When performing adjusted analyses, low socioeconomic status (odd ratio, 0.87; p = .001) and negative impact of reduction of income (odd ratio, 1.01; p = .004) were associated significantly with anxiety disorders in women but not in men. Conclusion: Our results suggest that anxiety disorders aggravate already existing gender differences in economic conditions, and that women with anxiety need additional support to attain socioeconomic security similar to that of men.

  • A genetic risk score is differentially associated with migraine with and without aura
  • 2017
  • Ingår i: Human Genetics. - 0340-6717 .- 1432-1203. ; 136:8, s. 999-1008

    • Although a number of migraine-associated single-nucleotide polymorphisms (SNP) with small effect size have been identified, little is known about the additive impact of these variants on migraine risk, frequency and severity. We investigated to what extent a genetic risk score (GRS) based on recently published, novel migraine-associated SNPs is associated with migraine prevalence, subtypes and severity in a large population-based sample. The sample comprised 446 subjects with migraine and 2511 controls from the CoLaus/PsyCoLaus study. Fifty-four SNPs earlier associated with migraine were selected. SNPs with a low impact on migraine prevalence in our sample were excluded using random forest. We combined the remaining 21 SNPs into a GRS and analyzed the association with migraine using logistic regression models. The GRS was significantly associated with migraine (OR = 1.56, p = 0.02) and migraine without aura (MWOA) (OR = 2.01, p = 0.003), but not with migraine with aura (MWA). The GRS was not associated with migraine frequency, intensity or interference with daily activities. We show that a GRS combining multiple genetic risk variants is associated with MWOA but not MWA, suggesting a different genetic susceptibility background underlying the two forms of migraine.

  • High leptin levels are associated with migraine with aura
  • 2017
  • Ingår i: Cephalalgia. - 0333-1024 .- 1468-2982. ; 37:5, s. 435-441

    • BACKGROUND: Migraine is a prevalent disorder characterised by recurrent headache attacks preceded or accompanied by aura in a subgroup of patients. Migraine often occurs together with major depressive disorder (MDD). Alterations of adipokine levels have been reported both in migraine and in MDD. In this cross-sectional study, we aimed to assess the associations between serum leptin and adiponectin levels and migraine or migraine subtypes. Analyses were adjusted for a lifetime history of MDD in order to investigate the association between adipokines and migraine under consideration of depression status.METHODS: We included 3025 participants from the CoLaus/PsyCoLaus study. The impact of leptin and adiponectin levels on a diagnosis of migraine was analysed by binary regression analyses, adjusting for variables known to influence adipokine levels. Subgroup analyses were conducted based on the presence of aura.RESULTS: Crude leptin levels were significantly higher in subjects with migraine than controls (Mann-Whitney U = 515,102, p = 6 × 10(-7)). When performing adjusted analyses, leptin levels were found to be significantly higher in subjects with migraine (odds ratio = 1.22, p = 0.024) and migraine with aura (odds ratio = 1.34, p = 0.004).CONCLUSION: High leptin levels might play a role in the pathogenesis of migraine and migraine with aura.
