Attention‐deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder. Symptoms often persist into adulthood, with a prevalence of 2.5–5% in adult populations. Twin studies in childhood consistently report high heritabilities of 70–80%, while studies in adult samples show only moderate heritability of 30–40% when estimated from self‐ratings. This review summarizes the available research on the heritability of ADHD in adults. Three key findings are outlined: (i) self‐ratings… Expand
Insights into attention-deficit/hyperactivity disorder from recent genetic studies
TLDR
Recent advances in quantitative and molecular genetic research from the past 5-10 years are summarized to anticipate further success with gene discovery, characterization of how the ADHD phenotype relates to other human traits and growing potential to use genomic risk factors for understanding clinical trajectories and for precision medicine approaches. Expand
Shared genetic background between children and adults with attention deficit/hyperactivity disorder
TLDR
It is confirmed that persistent ADHD in adults is a neurodevelopmental disorder and the existing hypothesis of a shared genetic architecture underlying ADHD and different traits to a lifespan perspective is extended. Expand

It is confirmed that persistent ADHD in adults is a neurodevelopmental disorder and the existing hypothesis of a shared genetic architecture underlying ADHD and different traits to a lifespan perspective is extended. Expand
Using an epidemiological approach to investigate sex differences in the manifestation of ADHD in youth and adulthood
TLDR
The findings suggest that females’ ADHD symptoms may need to be made more prominent by additional behavioural and emotional problems for them to receive clinical recognition for their ADHD, and that in the absence of prominent externalising problems females may be more easily missed in the ADHD diagnostic process. Expand
Self-report of ADHD shows limited agreement with objective markers of persistence and remittance
TLDR
The findings show that self-reported ADHD outcome is not as well reflected by cognitive-neurophysiological and movement correlates as the authors previously found for parent- reported ADHD. Expand
Genetics of attention-deficit/hyperactivity disorder: an update
TLDR
Recent findings from molecular genetics studies on both child and adult ADHD are presented and challenges and future directions for ADHD genetic studies are reviewed and discussed. Expand
Genetic and environmental contribution to the overlap between ADHD and ASD trait dimensions in young adults: a twin study
TLDR
Evidence is found for dimension-specific phenotypic and aetiological overlap between ADHD and ASD traits in adults and future studies investigating mechanisms underlying comorbidity may benefit from exploring several symptom-dimensions, rather than considering only broad diagnostic categories. Expand
Live fast, die young? A review on the developmental trajectories of ADHD across the lifespan
TLDR
A severe lack of knowledge on lifespan aspects in ADHD still exists for nearly every aspect reviewed, and it is encouraged that large-scale research efforts to overcome those knowledge gaps through appropriately granular longitudinal studies are encouraged. Expand
Attention-deficit hyperactivity disorder in adults: A systematic review and meta-analysis of genetic, pharmacogenetic and biochemical studies
TLDR
There were not enough genetic, pharmacogenetic and biochemical studies of ADHD in adults and that more investigations are needed, which confirmed a significant role of BAIAP2 and DHA in the etiology of ADHD exclusively in adults. Expand
Genetics of attention deficit hyperactivity disorder
TLDR
From studies of copy number variants, it is learned that the rare insertions or deletions account for part of ADHD’s heritability, which has implicated new biological pathways that may eventually have implications for treatment development. Expand

Efficacy of retrospective recall of attention-deficit hyperactivity disorder symptoms: A twin study.
TLDR
Assessing ADHD in adult probands may be less accurate than with children or adolescents, but since it demonstrates several characteristics in common with other assessment techniques it remains a viable diagnostic and research strategy, even with population samples. Expand
Different heritabilities but shared etiological influences for parent, teacher and self-ratings of ADHD symptoms: an adolescent twin study
TLDR
There were shared genetic influences for parent, teacher and self-ratings of ADHD symptoms, indicating that different informants rated some of the same aspects of behavior. Expand

TLDR
Heritability for ADHD features in adults is present, but is substantially lower than it is in children, with some evidence for assortative mating. Expand
Phenotypic and measurement influences on heritability estimates in childhood ADHD
TLDR
Findings from population-based twin studies regarding the influence of subtypes, assessment instruments, rater effects, sex differences, and comorbidity rates on ADHD heritability estimates are reported. Expand

TLDR
Progress in identifying aADHD risk genes may provide tools for the prediction of disease progression in the clinic and better treatment, and ultimately may help to prevent persistence of ADHD into adulthood. Expand
The heritability of clinically diagnosed attention deficit hyperactivity disorder across the lifespan
TLDR
The finding of high heritability for clinically diagnosed ADHD in adults indicates that the previous reports of low heritability are best explained by rater effects, and that gene-identification studies of ADHD in adult need to consider pervasiveness and developmentally informative data. Expand

TLDR
Estimates of ADHD prevalence and correlates in the World Health Organization World Mental Health Survey Initiative should be considered more seriously in future epidemiological and clinical studies than is currently the case. Expand
Contrast Effects and Sex Influence Maternal and Self-Report Dimensional Measures of Attention-Deficit Hyperactivity Disorder
TLDR
Heritability difference between maternal and self- report ADHD was due to greater variance of male specific environment in self-report data, and broad-sense heritability was equal across sex for maternal-report inattention, hyperactivity-impulsivity and combined ADHD. Expand
Genetic influences on the stability of attention-deficit/hyperactivity disorder symptoms from early to middle childhood
TLDR
Parents' ratings of ADHD symptoms showed moderate stability across the ages, which was mainly due to shared genetic influences, and estimates of genetic and environmental influences were obtained for girls and boys. Expand
Genetic and environmental influences on adult attention deficit hyperactivity disorder symptoms: a large Swedish population-based study of twins
TLDR
The findings of moderate broad heritability estimates are consistent with previous literature onSelf-rated ADHD symptoms in older children, adolescents and adults and retrospective reports of self-rated childhood ADHD by adults but differ from studies of younger children with informant ratings.
