Kravariti, Eugenia; Jacobson, Clare; Morris, Robin; Frangou, Sophia; Murray, Robin M.; Tsakanikos, Elias; Habel, Alex; Shearer, Jo – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
The 22q11.2 deletion syndrome (22qDS) and schizophrenia have genetic and neuropsychological similarities, but are likely to differ in memory profile. Confirming differences in memory function between the two disorders, and identifying their genetic determinants, can help to define genetic subtypes in both syndromes, identify genetic risk factors…

Biswas, Parthasarathy – Journal of Indian Association for Child and Adolescent Mental Health, 2008
In the last decade there has been an exponential increase in studies on neurobiological measures in childhood-onset schizophrenia (COS). There seems to be a consensus that structural changes in COS are more marked than in adolescence-onset (AdOS) or adult-onset schizophrenia (AOS). Atrophy of total brain volume is progressive throughout the course…

Dumontheil, Iroise; Burgess, Paul W.; Blakemore, Sarah-Jayne – Developmental Medicine & Child Neurology, 2008
Information on the development and functions of rostral prefrontal cortex (PFC), or Brodmann area 10, has been gathered from different fields, from anatomical development to functional neuroimaging in adults, and put forward in relation to three particular cognitive and behavioural disorders. Rostral PFC is larger and has a lower cell density in…

Studies of Visual Information Processing in Schizophrenic Children.
Peer reviewed Peer reviewed
Asarnow, Robert F.; Sherman, Tracy – Child Development, 1984
Results of three experiments suggest that groups of schizophrenic, younger normal, and older normal children used a serial information-processing strategy while performing on a partial report version of a span of apprehension task. Impairment of schizophrenic children on the partial report versions seemed to reflect inefficiencies in the…

Banaschewski, Tobias; Brandeis, Daniel – Journal of Child Psychology and Psychiatry, 2007
Background: Monitoring brain processes in real time requires genuine subsecond resolution to follow the typical timing and frequency of neural events. Non-invasive recordings of electric (EEG/ERP) and magnetic (MEG) fields provide this time resolution. They directly measure neural activations associated with a wide variety of brain states and…

Clegg, J.; Hollis, C.; Mawhood, L.; Rutter, M. – Journal of Child Psychology and Psychiatry, 2005
Background: Little is known on the adult outcome and longitudinal trajectory of childhood developmental language disorders (DLD) and on the prognostic predictors. Method: Seventeen men with a severe receptive DLD in childhood, reassessed in middle childhood and early adult life, were studied again in their mid-thirties with tests of intelligence…
