Harris, Susan W.; Hessl, David; Goodlin-Jones, Beth; Ferranti, Jessica; Bacalman, Susan; Barbato, Ingrid; Tassone, Flora; Hagerman, Paul J.; Herman, Kristin; Hagerman, Randi J. – American Journal on Mental Retardation, 2008
Autism, which is common in individuals with fragile X syndrome, is often difficult to diagnose. We compared the diagnostic classifications of two measures for autism diagnosis, the ADOS and the ADI-R, in addition to the DSM-IV-TR in 63 males with this syndrome. Overall, 30% of the subjects met criteria for autistic disorder and 30% met criteria…

Levy, Yonata; Ebstein, Richard P. – Journal of Child Psychology and Psychiatry, 2009
The inherent imprecision of behavioral phenotyping is the single most important factor contributing to the failure to discover the biological factors that are involved in psychiatric and neurodevelopmental disorders (e.g., Bearden & Freimer, 2006). In this review article we argue that in addition to an appreciation of the inherent complexity at…

Leonard, Laurence B. – American Journal of Speech-Language Pathology, 2009
Purpose: To propose that the diagnostic category of "expressive language disorder" as distinct from a disorder of both expressive and receptive language might not be accurate. Method: Evidence that casts doubt on a pure form of this disorder is reviewed from several sources, including the literature on genetic findings, theories of language…

Studies into the prevalence of personality disorder in the population of people with an intellectual disability indicate significant variations, which have no clear explanation. Method: Work on personality disorder and personality…

Wheeler, Linda – Emotional & Behavioural Difficulties, 2010
This article seeks to evaluate and take further the discussion put forward by Visser and Jehan ("Emotional and Behavioural Difficulties" 14, no. 2: 127-40). It begins by focusing on the biomedical discourse, its dominance in the academic and professional literature and why the existence of Attention Deficit Hyperactivity Disorder (ADHD) as a…

Bjork, James M.; Chen, Gang; Smith, Ashley R.; Hommer, Daniel W. – Journal of Child Psychology and Psychiatry, 2010
Background: Opponent-process theories of externalizing disorders (ExD) attribute them to some combination of overactive reward processing systems and/or underactive behavior inhibition systems. Reward processing has been indexed by recruitment of incentive-motivational neurocircuitry of the ventral striatum (VS), including nucleus accumbens…

Sikora, Darryn M.; Hartley, Sigan L.; McCoy, Robin; Gerrard-Morris, Aimee E.; Dill, Kameron – Research in Autism Spectrum Disorders, 2008
Over the past few decades, the reported number of children identified as having one of the Autism Spectrum Disorders (ASD) has increased exponentially. One proposed reason for the dramatic increase in the prevalence of ASD is diagnostic substitution, whereby children with other disorders incorrectly receive a diagnosis of ASD. Little research has…

Matson, Johnny L.; Wilkins, Jonathan – Research in Autism Spectrum Disorders, 2008
The autism spectrum disorders (ASD) have generated great interest among clinicians and researchers. Once considered rare, recent epidemiological data now suggests rates of up to 1 in 150 people. One of the most frequent of the ASD, Asperger's syndrome (AS), has been known as a disorder for as long as autism, which is easily the most visible of…

Martel, Michelle M.; Gremillion, Monica; Roberts, Bethan; von Eye, Alexander; Nigg, Joel T. – Psychological Assessment, 2010
Attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) frequently co-occur. Comorbidity of these 2 childhood disruptive behavior domains has not been satisfactorily explained at either a structural or etiological level. The current study evaluated a bifactor model, which allows for a "g" factor in addition to…
