Complex ADHD in a Child With Tic Disorder

Jaxon is a healthy 12-year-old boy who is referred to your clinic for medication management. He was diagnosed with ADHD using a validated questionnaire at age 9 years. He is currently prescribed OROS methylphenidate 54 mg capsules once daily in the morning, which he has taken for 3 years. This has generally worked well to improve his attention, focus, task persistence, and task completion. However, his parents now report increasing disruptive behaviors over the past 18 months, both at home and at school. There have been no major stressors over this period nor significant life changes or trauma in Jaxon's history.Jaxon's teachers report that although he remains in his seat, he constantly "squirms" and moves about. He also makes quick, jerky movements with his hands several times each class period. They report no specific trigger or activity for when this movement occurs, but report it being more intense when Jaxon is working hard to concentrate and stay focused. His mother also reports noticing the frequency increase if Jaxon thinks he is in trouble or when he is very excited (e.g., when he is playing video games). His parents share home videos to support these concerns.His teachers report problems with attention, fidgeting, and talking out of turn. They also report that his movements distract and disrupt the class. These reports are most often from his afternoon classes. Academically, he is doing well. He turns in most of his work, but his grades have dropped this semester. His teacher reports that he seems to lack the focus to complete his assignments and he rushes through them to go to the next activity.When you talk to Jaxon, he reports that he likes school, but he does not like how often he gets into trouble. He admits he gets embarrassed during quiet time when his hands randomly "move without me moving them."When observing Jaxon, you notice that he fidgets in his seat, often moving his hands over anything that is holding his attention (toys, papers). He is also verbally impulsive, interrupting the discussion with his mother multiple times during the visit. Twice, you witness a brisk single jerk of his right hand. It originates at the wrist and rotates away from his body with his hand closed. There was no accompanying vocalization with this movement.His parents are requesting a medication adjustment or change.
