It is pleasing to see the volume of research taking place in the field of attention deficit hyperactivity disorder (ADHD) and especially pleasing to see it being conducted across many countries and cultures. In this edition of abstract watch, we summarise a study by Bihlar Muld et al, which highlights the importance of identifying and treating comorbid substance use disorders. We also explore a trial of the relatively new treatment method of trigeminal nerve stimulation by McGough et al, and Moëll et al build a good case for utilising smartphones in the management of adult ADHD. We finish with a study by Kanazawa on the importance of electroencephalogram readings as part of the screening protocol for ADHD, a topic that is likely to raise some debate.
