Factors associated with level of intellectual functioning and adaptive behaviour were analysed.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Eight\u2010six per cent (\n n<\/jats:italic>\n \u00a0=\u200936) of the children fulfilled DSM\u20105 criteria for intellectual disability (29% [\n n<\/jats:italic>\n \u00a0=\u200912] mild intellectual disability, 24% [\n n<\/jats:italic>\n \u00a0=\u200910] moderate intellectual disability, 33% [\n n<\/jats:italic>\n \u00a0=\u200914] severe intellectual disability, 0% profound intellectual disability) and 93% (\n n<\/jats:italic>\n \u00a0=\u200939) had an adaptive behaviour composite more than two standard deviations below the mean. Communication was a significant weakness compared with daily living skills (\n p<\/jats:italic>\n \u00a0<\u20090.001; mean difference 95% confidence interval [CI] \u20138.193 to \u22124.092) and socialization (\n p<\/jats:italic>\n \u00a0=\u20090.001; mean difference 95% CI 6.511 to \u22121.775) on the Vineland Adaptive Behavior Scales, Second Edition. The only factors significantly associated with both decreased adaptive behaviour and presence of severe intellectual disability was the presence of increased autistic symptoms and younger age.\n <\/jats:p>\n <\/jats:sec>\n \n Interpretation<\/jats:title>\n Children with Dravet syndrome have a very high level of intellectual disability and almost all have significant deficits in adaptive behaviour. Greater deficits in adaptive behaviour and greater severity of intellectual disability are associated with the presence of increased autistic symptoms, highlighting the need for comprehensive neurodevelopmental assessment for all affected children.<\/jats:p>\n <\/jats:sec>\n \n What this paper adds<\/jats:title>\n \n \n \n \n Eighty\u2010six per cent (\n n<\/jats:italic>\n \u00a0=\u00a036)
