“…There is a partial overlap of its symptoms with those of another important childhood disorder, ADHD. The questions that have arisen are 1., whether PDD (broadly defined) and ADHD are really discrete syndromes (Hattori et al 2006), and 2., if this is so, whether a combined diagnosis of PDD-NOS and ADHD is ever justified (Luteijn et al 2000). To shed more light on these questions, we investigated whether children diagnosed as having PDD-NOS or ADHD, and children meeting the criteria for both diagnoses could be distinguished on the basis of their intelligence profiles.…”

Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) and Attention Deficit/ Hyperactivity Disorder (ADHD) have partly overlapping symptoms. It can also be debated whether a third diagnostic category exists: children with a combined diagnosis. In this study an attempt was made to distinguish among the three groups on the basis of intelligence (WISC-III) profiles. It was found that the PDD-NOS group had higher verbal and performance IQ's, as well as higher WISC-III index scores than the ADHD group. Subtests Block Design and Mazes discriminated best. It was concluded that based on intelligence scores, only PDD-NOS and ADHD emerged as distinct categories, whereas the combined diagnosis did not. Future research on the distinctiveness of these diagnostic groups, however, should include variables other than IQ.

“…There has been recent interest in the diagnostic overlap and similarities between ADHD and ASD (Hattori et al 2006;Luteijn et al 2000;Reiersen et al 2007;Ronald et al 2008). It has long been acknowledged that children with ADHD have social and communication difficulties as part of the ADHD complex (Greene et al 1996;Hoza 2007;Hoza et al 2005;Nijmeijer et al 2008;Pelham and Bender 1982).…”

It is hypothesised that autism symptoms are present in Attention-Deficit/Hyperactivity Disorder (ADHD), are familial and index subtypes of ADHD. Autism symptoms were compared in 821 ADHD probands, 1050 siblings and 149 controls. Shared familiality of autism symptoms and ADHD was calculated using DeFriesFulker analysis. Autism symptoms were higher in probands than siblings or controls, and higher in male siblings than male controls. Autism symptoms were familial, partly shared with familiality of ADHD in males. Latent class analysis using SCQ-score yielded five classes; Class 1(31%) had few autism symptoms and low comorbidity; Classes 2-4 were intermediate; Class 5(7%) had high autism symptoms and comorbidity. Thus autism symptoms
