METHOD: ADHD-concordant pairs (21 probands and their affected siblings), ADHD-discordant pairs (18 probands and their nonaffected siblings), and a group of unrelated, demographically balanced, healthy individuals (N=24) were compared on measures of response inhibition, ADHD behavior, impairment, and environmental risk. RESULTS: Concordant-pair probands, their affected siblings, and discordant-pair probands exhibited inhibitory control impairment relative to healthy comparison subjects. The performance of nonaffected siblings was intermediate between that of ADHD children and the healthy comparison subjects. Group differences persisted after age was controlled, and performance was not correlated with the number of ADHD symptoms. In ADHD-concordant sibling pairs, there was a significant relationship between proband and sibling inhibition deficit. In ADHD-discordant sibling pairs, inhibition deficit was evident in half of the nonaffected siblings of probands with an inhibition deficit. Groups did not differ in exposure to environmental risks. CONCLUSIONS: Impaired inhibitory control aggregates in the family members of individuals with ADHD and may serve as an indicator of genetic vulnerability to the disorder.","is_dataset_classified":null,"base_score":4.48863636973214,"endowment":4.48863636973214,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"15930055","pmcid":null,"openalex_id":"https://openalex.org/W2111832122","authors":[],"funders":[],"total_grants":0,"fwci":3.517,"citation_percentile":0.92698447,"influential_citations":0,"citation_trend":[{"year":2012,"count":1},{"year":2013,"count":3},{"year":2014,"count":12},{"year":2015,"count":5},{"year":2016,"count":4},{"year":2017,"count":5},{"year":2018,"count":2},{"year":2019,"count":1},{"year":2020,"count":5},{"year":2021,"count":4},{"year":2022,"count":3},{"year":2023,"count":1},{"year":2025,"count":1},{"year":2026,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://psychiatryonline.org/doi/10.1176/appi.ajp.162.6.1076","host_type":"publisher"},{"url":"https://doi.org/10.1176/appi.ajp.162.6.1076","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/15930055","host_type":"repository"}],"fields_of_study":["Attention Deficit Hyperactivity Disorder","Neural and Behavioral Psychology Studies","Historical and Modern Theater Studies","Attention Deficit Disorder with Hyperactivity","Genetic Markers","Genetic Predisposition to Disease","Humans","Inhibition, Psychological","Phenotype","Psychomotor Performance","Reaction Time","Risk Factors","Siblings"],"mesh_terms":["Attention Deficit Disorder with Hyperactivity","Genetic Markers","Humans","Inhibition, Psychological","Phenotype","Psychomotor Performance","Reaction Time","Risk Factors","Genetic Predisposition to Disease","Siblings"],"keywords":["Proband","Sibling","Concordance","Attention deficit hyperactivity disorder","Psychology","Endophenotype","Medicine","Clinical psychology","Psychiatry","Developmental psychology","Internal medicine","Genetics","Biology","Cognition","Gene"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-06T17:44:12.285893Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
