  • Applying polygenic risk scoring for psychiatric disorders to a large family with bipolar disorder and major depressive disorder
  • 2018
  • Ingår i: Communications Biology. - Nature Publishing Group. - 2399-3642. ; 1
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>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 (<em>n</em> ~ 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.</p>

  • 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

    • <p>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 &lt; .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.</p>

  • 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

    • <p>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.</p>

  • Major depression subtypes are differentially associated with migraine subtype, prevalence and severity.

    • <p><strong>OBJECTIVE:</strong> Migraine and major depressive disorder show a high rate of comorbidity, but little is known about the associations between the subtypes of major depressive disorder and migraine. In this cross-sectional study we aimed at investigating a) the lifetime associations between the atypical, melancholic, combined and unspecified subtype of major depressive disorder and migraine with and without aura and b) the associations between major depressive disorder and its subtypes and the severity of migraine.</p><p><strong>METHODS:</strong> A total of 446 subjects with migraine (migraine without aura: n = 294; migraine with aura: n = 152) and 2511 controls from the population-based CoLaus/PsyCoLaus study, Switzerland, were included. Associations between major depressive disorder subtypes and migraine characteristics were tested using binary logistic or linear regression.</p><p><strong>RESULTS:</strong> Melancholic, combined and unspecified major depressive disorder were associated with increased frequency of migraine with aura, whereas only melancholic major depressive disorder was associated with increased frequency of migraine without aura. Lifetime and unspecified major depressive disorder were associated with severe migraine intensity among subjects with migraine with aura but not migraine without aura, while combined major depressive disorder was associated with higher migraine frequency independently from migraine subtype.</p><p><strong>CONCLUSION:</strong> This study suggests that melancholic but not atypical major depressive disorder is associated with migraine and migraine subtypes. Future studies exploring pathophysiological mechanisms shared between melancholic depression and migraine are warranted.</p>
