Hooper, Stephen R.; Curtiss, Kathleen; Schoch, Kelly; Keshavan, Matcheri S.; Allen, Andrew; Shashi, Vandana – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
The present study sought to examine the longitudinal psychoeducational, neurocognitive, and psychiatric outcomes of children and adolescents with chromosome 22q11.2 deletion syndrome (22q11DS), a population with a high incidence of major psychiatric illnesses appearing in late adolescence/early adulthood. Little is known of the developmental…

Osorio, Ana; Cruz, Raquel; Sampaio, Adriana; Garayzabal, Elena; Martinez-Regueiro, Rocio; Goncalves, Oscar F.; Carracedo, Angel; Fernandez-Prieto, Montse – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
Williams syndrome is characterized by impairments in executive functions (EFs). However, it remains unknown how distinct types of EFs relate to intelligence in this syndrome. The present study analyzed performance on working memory, inhibiting and shifting, and its links to IQ in a sample of 17 individuals with WS, and compared them with a group…

Duijff, Sasja; Klaassen, Petra; Beemer, Frits; Swanenburg de Veye, Henriette; Vorstman, Jacob; Sinnema, Gerben – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
The purpose of this study was to explore the relationship between intelligence and visual motor integration skills in 5-year-old children with 22q11-deletion syndrome (22q11DS) (N = 65, 43 females, 22 males; mean age 5.6 years (SD 0.2), range 5.23-5.99 years). Sufficient VMI skills seem a prerequisite for IQ testing. Since problems related to…

Howley, Sarah A.; Prasad, Sarah E.; Pender, Niall P.; Murphy, Kieran C. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
22q11.2 Deletion Syndrome (22q11DS) is a common microdeletion disorder associated with mild to moderate intellectual disability and specific neurocognitive deficits, particularly in visual-motor and attentional abilities. Currently there is evidence that the visual-motor profile of 22q11DS is not entirely mediated by intellectual disability and…

Van Aken, Katrijn; Swillen, Ann; Beirinckx, Marc; Janssens, Luc; Caeyenberghs, Karen; Smits-Engelsman, Bouwien – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
To examine whether children with a 22q11.2 Deletion syndrome (22q11.2DS) are able to use prospective control, 21 children with 22q11.2DS (mean age=9.6 [plus or minus] 1.9; mean FSIQ=73.05 [plus or minus] 10.2) and 21 control children (mean age=9.6 [plus or minus] 1.9; mean FSIQ=73.38 [plus or minus] 12.0) were asked to perform a visuo-manual…

Perez-Garcia, D.; Granero, R.; Gallastegui, F.; Perez-Jurado, L. A.; Brun-Gasca, C. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Williams-Beuren syndrome (WBS) is a genetically determined neurodevelopmental disorder caused by a heterozygous deletion of 26-28 genes on chromosome band 7q11.23. During the past few years, researchers and clinicians have significantly contributed to define the phenotype of the syndrome, including its cognitive and behavioral aspects. However, it…

Niklasson, Lena; Gillberg, Christopher – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
The primary objective of this study was to study the impact of ASD/ADHD on general intellectual ability and profile, executive functions and visuo-motor skills in children and adults with 22q11 deletion syndrome (22q11DS). A secondary aim was to study if gender, age, heart disease, ASD, ADHD or ASD in combination with ADHD had an impact on general…
