Conclusions
impulsivity, predominantly inattentive
The results of this study demonstrated improvements in performance in the core symptom inattention, after given one single-dose placebo. This implies that knowledge of the effect of placebo can be useful when treating patients with predominantly inattentive presentation. In addition, we noted that activity problems increased during baseline and after placebo intake during the QbTest while inattention and impulsivity difficulties remained at the same level during the QbTest. This finding could be relevant in the interpretation of results from the QbTest with new patients.
