Complex Attention-Deficit Hyperactivity Disorder in a 4-Year-Old With Repaired Critical Congenital Heart Disease and Autism Spectrum Disorder.

Abstract

Congenital heart disease (CHD) is a risk factor for developmental delay and for attention-deficit hyperactivity disorder (ADHD). The Cardiac Neurodevelopmental Outcome Collaborative has developed recommendations for ongoing monitoring of this at-risk population to be able to detect developmental, learning, and behavioral concerns, as they become apparent as a child ages. A 4-year-old boy with tetralogy of Fallot with a ventricular septal defect repaired in infancy was followed periodically in the cardiac neurodevelopmental follow-up clinic and diagnosed with autism spectrum disorder as well as additional developmental and medical issues. He received early childhood special education and therapeutic interventions as well as social skills training and applied behavior analysis. At age 4 years, Alex presented with symptoms of hyperactivity, inattention, impulsivity, and immediate safety concerns for elopement. The clinician diagnosed him with ADHD-combined type. He was recommended to start medication in addition to behavioral and developmental supports. Managing medications in a child with CHD and ADHD presents unique challenges, and medication decisions were carefully made in collaboration with the child's cardiologist. After some medication adjustments and ongoing behavioral therapy to address behaviors associated with ADHD and autism spectrum disorder, the child is doing well academically and socially. Attention-deficit hyperactivity disorder medications can be safely prescribed in patients with CHD. However, pharmacotherapy for co-occurring ADHD and CHD needs an additional level of oversight and collaboration between cardiology and prescribing clinicians. Behavioral therapies can be transdiagnostic and address challenges associated with autism and symptoms related to ADHD.
