Median age of participants was 10 years, the age range was between 32 and 289 months. They underwent psychiatric examinations and neuropsychological measurements using a comprehensive assessment battery. Additionally, parental information was gathered through standardized interviews and questionnaires. Findings were compared with those from the literature.<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold> All participants showed profound intellectual disability, amiable demeanour with minimal maladaptive behaviours, severe impairments of communication and language, and intense, frequent motor stereotypies. Impairments in all participants were beyond what would be expected for cognitive abilities, fitting a classification of ASD.<\/jats:p><jats:p><jats:bold>Interpretation\u2002<\/jats:bold> Patients with PTHS are characterized not only by specific physical and genetic manifestations but also by specific behavioural and cognitive characteristics. Studying behaviour and cognition may improve diagnosis and prognosis, allows recognition of comorbidities, and contributes to adequate counselling of families.<\/jats:p>","DOI":"10.1111\/j.1469-8749.2012.04339.x","type":"journal-article","created":{"date-parts":[[2012,6,19]],"date-time":"2012-06-19T16:21:46Z","timestamp":1340122906000},"page":"925-931","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["Development, cognition, and behaviour in Pitt\u2013Hopkins syndrome"],"prefix":"10.1111","volume":"54","author":[{"given":"INGRID D C","family":"VAN BALKOM","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PIETER JELLE","family":"VUIJK","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MARIJKE","family":"FRANSSENS","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HANS W","family":"HOEK","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"RAOUL C M","family":"HENNEKAM","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,6,19]]},"reference":[{"key":"e_1_2_8_2_2","first-page":"182","article-title":"A syndrome of mental retardation, wide mouth, and intermittent overbreathing","volume":"14","author":"Pitt D","year":"1978","journal-title":"Aust Paediatr J"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1754.1993.tb00472.x"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19980123)75:3<273::AID-AJMG9>3.0.CO;2-R"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1523"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.mcd.0000184973.14775.32"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1086\/515582"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/ddm099"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1086\/515583"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.2008.060129"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejmg.2007.12.002"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/humu.20859"},{"key":"e_1_2_8_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/humu.20935"},{"key":"e_1_2_8_14_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-0004.2010.01380.x"},{"key":"e_1_2_8_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.34070"},{"key":"e_1_2_8_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajhg.2009.10.004"},{"key":"e_1_2_8_17_2","doi-asserted-by":"publisher","DOI":"10.1093\/schbul\/sbq035"},{"key":"e_1_2_8_18_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2788.2011.01451.x"},{"key":"e_1_2_8_19_2","volume-title":"Bayley Scales of Infant Development \u2013 II","author":"Van der Meulen BF","year":"2002"},{"key":"e_1_2_8_20_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.PEP.0000136005.41585.FE"},{"key":"e_1_2_8_21_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02172145"},{"key":"e_1_2_8_22_2","author":"de Jonge M","year":"2007","journal-title":"Autisme Diagnostisch Interview \u2013 Revised"},{"key":"e_1_2_8_23_2","volume-title":"Autism Diagnostic Interview \u2013 Revised","author":"Rutter M","year":"2003"},{"key":"e_1_2_8_24_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10803-007-0448-3"},{"key":"e_1_2_8_25_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0010887"},{"key":"e_1_2_8_26_2","volume-title":"Vineland Adaptive Behaviour Scales","author":"Sparrow SS","year":"1984"},{"key":"e_1_2_8_27_2","volume-title":"Vineland\u2010Z.
