Background: This study aimed to identify the mathematical domains affected in adults with neurofibromatosis 1 (NF1) and the impact of the numerical difficulties on the patients' activities of daily living. Methods: We assessed 28 adult patients with NF1 and 28 healthy control participants. All participants completed the standardised battery of…

Jacola, L. M.; Byars, A. W.; Hickey, F.; Vannest, J.; Holland, S. K.; Schapiro, M. B. – Journal of Intellectual Disability Research, 2014
Background: Previous studies have documented differences in neural activation during language processing in individuals with Down syndrome (DS) in comparison with typically developing individuals matched for chronological age. This study used functional magnetic resonance imaging (fMRI) to compare activation during language processing in young…

Lanfranchi, S.; Baddeley, A.; Gathercole, S.; Vianello, R. – Journal of Intellectual Disability Research, 2012
Background: Recent studies have shown that individuals with Down syndrome (DS) are poorer than controls in performing verbal and visuospatial dual tasks. The present study aims at better investigating the dual task deficit in working memory in individuals with DS. Method: Forty-five individuals with DS and 45 typically developing children matched…

Baker, S.; Hooper, S.; Skinner, M.; Hatton, D.; Schaaf, J.; Ornstein, P.; Bailey, D. – Journal of Intellectual Disability Research, 2011
Background: Working memory problems have been targeted as core deficits in individuals with Fragile X syndrome (FXS); however, there have been few studies that have examined working memory in young boys with FXS, and even fewer studies that have studied the working memory performance of young boys with FXS across different degrees of complexity.…

Lanfranchi, S.; Carretti, B.; Spano, G.; Cornoldi, C. – Journal of Intellectual Disability Research, 2009
Background: Recent studies have demonstrated that individuals with Down syndrome (DS) present both central and verbal working memory deficits compared with controls matched for mental age, whereas evidence on visuospatial working memory (VSWM) has remained ambiguous. The present paper uses a battery of VSWM tasks to test the hypothesis that…

Adams, D.; Oliver, C.; Kalsy, S.; Peters, S.; Broquard, M.; Basra, T.; Konstandinidi, E.; McQuillan, S. – Journal of Intellectual Disability Research, 2008
Background: Behavioural changes associated with dementia in Down syndrome are well documented, yet little is known about the effect of such behaviours on carers and referral. By comparing the behavioural and cognitive profiles of individuals referred for a dementia assessment with those of individuals not referred, some insight can be gained into…

Pyo, G.; Curtis, K.; Curtis, R.; Markwell, S. – Journal of Intellectual Disability Research, 2009
Background: Decline in orientation skill has been reported as an early indicator of Dementia of Alzheimer's Type (DAT). Orientation subtest of the Working Group's Test Battery was examined whether this test is useful to identify DAT patients among adults with moderate to severe ID. Methods: Sixteen DAT patients and 35 non-demented normal controls…
