We studied the relationship between patients with attention-

deficit/hyperactivity disorder (ADHD) and those with pervasive

developmental disorders (PDD), using the High-Functioning Autism

Spectrum Screening Questionnaire (ASSQ) and ADHD Rating Scale-IV. The

ASSQ scores of the PDD group and the ADHD group were significantly

higher than the control group. Furthermore, the PDD group scored

higher than the ADHD group. Both groups also showed higher scores

than the control group in all three domains, that is, restricted and

repetitive behavior, social interaction, and communication problem.

The PDD and the ADHD group showed no significant difference in the

domains of communication problem, and restricted and repetitive

behavior. The PDD group had a higher score than the ADHD group only

in the social interaction domain. In total score, inattention score,

and hyperactivity/impulsivity score on the ADHD Rating Scale-IV, both

groups were significantly higher than the control group. Between the

ADHD and the PDD groups, there was no significant difference in the

three scores. The patients with strictly diagnosed ADHD had many PDD-

related symptoms, and the patients with PDD had many ADHD-related

symptoms. It therefore seems difficult to make a distinction between

ADHD and PDD by using the present diagnostic criteria in the DSM-IV.

We should evaluate each patient in terms of both sets of criteria.

Well this is very interesting! Especially considering how many

people are diagnosed with ADHD.
