Mindfulness and associations with symptoms of insomnia, anxiety and depression in early adulthood: A twin and sibling study

MRI‐visible dilated perivascular spaces in healthy young adults: A twin heritability study

“…We implemented the classical twin study design, in which narrow‐sense heritability ( h 2 ) was defined as the ratio of variance from a phenotypic measurement, which can be shown as additive genetic variation [A]/total observed variation (genetics [A] + shared environment [C] + unique environment [E]). Since the common or shared environment is considered to be the same within a family, [C] was set as 1 for all twins and nontwin siblings (Patel et al, 2017; Schneider et al, 2019). The genetic variation [A] was set as 1 for MZ twin pairs and 0.5 for DZ twins and nontwin siblings based on previous literature assuming that DZ twins and nontwin siblings share on average 50% of their genes (Patel et al, 2017, 2018).…”

Efeitos da meditação associada a educação em neurociências da dor em adultos com fibromialgia: ensaio clínico controlado e randomizado

“…A técnica também consistia no treino de deixar de ser menos reativos a emoções negativas do dia a dia bem como condicionar os momentos de O Mindfulness atualmente tem ganhado destaque no âmbito das neurociências por suas contribuições, dentre elas a de nível cerebral (29)(30) . As pesquisas que envolvem intervenções baseadas em Mindfulness têm mostrado consideráveis melhorias nos níveis de insônia, depressão, ansiedade e manejo da fibromialgia, o que sugere um papel importante em teorias cognitivas do sono e em comportamentos mal adaptativos em relação a dor (15,(30)(31) . Em consonância com a literatura, nosso estudo demonstrou tais benefícios.…”

Comparison of the Differences in State-Trait Anxiety Inventory Scores and Insomnia Histories between Monozygotic and Dizygotic Twins: A Cross-Sectional Study Using KoGES HTS Data

“…Multiple candidate genes for gene–environmental interactions in anxiety have been suggested [ 5 ]. Insomnia is one of the associated factors for anxiety, which also has heritability [ 6 , 7 , 8 ]. In a meta-analysis of twin studies, approximately 40% of heritable factors contributed to the occurrence of insomnia [ 6 ].…”
