A crossover 'placebo'-controlled, double-blind design was used to examine the effectiveness of an oligoantigenic diet in 49 children with hyperactive/disruptive behavior disorder. Effects of diet were compared with those yielded by stimulant medication (methylphenidate). The study was conducted in an inpatient unit at the Department of Child and Adolescent Psychiatry, Central Institute of Mental Health, Mannheim. Change in behavior was measured in standardized situations by trained raters, including behavior assessment when testing with CPT and PAT, during a free play situation, and at school. Twelve children (24%) showed significant behavioral improvement in two behavior ratings during diet relative to control diet conditions. Methylphenidate used in 36 children yielded more responders (44%) than diet. The amount of positive changes in behavior in those who received both treatments was about the same. Although only effective in a minority of children, dietary treatment cannot be neglected as a possible access to treating hyperactive/disruptive children and merits further investigation.

Varying levels of attention and impulsivity deficits are core features of the three subtypes of adult attention deficit-hyperactivity disorder (ADHD). To date, little is known about the neurobiological correlates of these subtypes. Development of a translational animal model is essential to improve our understanding and improve therapeutic strategies. The 5-choice continuous performance task (5C-CPT) in rats can be used to examine different forms of attention and impulsivity. Adult rats were trained to pre-set 5C-CPT criterion and subsequently separated into subgroups according to baseline levels of sustained attention, vigilance, premature responding and response disinhibition in the 5C-CPT. The behavioural subgroups were selected to represent the different subtypes of adult ADHD. Consequently, effects of the clinically used pharmacotherapies (methylphenidate and atomoxetine) were assessed in the different subgroups. Four subgroups were identified: low-attentive (LA), high-attentive (HA), high-impulsive (HI) and low-impulsive (LI). Methylphenidate and atomoxetine produced differential effects in the subgroups. Methylphenidate increased sustained attention and vigilance in LA animals, and reduced premature responding in HI animals. Atomoxetine also improved sustained attention and vigilance in LA animals, and reduced response disinhibition and premature responding in HI animals. This is the first study using adult rats to demonstrate the translational value of the 5C-CPT to select subgroups of rats, which may be used to model the subtypes observed in adult ADHD. Our findings suggest that this as an important paradigm to increase our understanding of the neurobiological underpinnings of adult ADHD-subtypes and their response to pharmacotherapy.
