Serotonin transporter in attention-deficit hyperactivity disorder – preliminary results from a positron emission tomography study

Abstract The serotonin transporter (SERT) in attention-deficit hyperactivity disorder (ADHD) patients has not been explored by earlier positron emission tomography (PET) studies. We measured SERT availability in female ADHD patients ( n =8) and healthy controls ( n =14) with PET and [ 11 C]MADAM as a tracer. No significant group differences in [ 11 C]MADAM binding potential were noted.
