Association of Attention Deficit Hyperactivity Disorder with the Use of Oral Propranolol in Infantile Haemangiomas: An Ambispective Comparative Study.

Previous studies have raised concerns about the effects of oral propranolol on the central nervous system in infants, the exact measure and mechanism and the long-term follow-up of which is less well studied. This was an ambispective comparative study of children with infantile haemangioma (IH) followed by a repeat visit 4-10 years after completion of propranolol therapy. Parents were asked about psychologic functioning along with an initial screening examination. All patients were evaluated by a paediatric psychiatrist. After evaluation by the Strength and Difficulties Questionnaire, and subsequently by the paediatric psychiatrist, 2 of 12 patients (16.67%) showed features of attention deficit hyperactivity disorder in comparison to 0 of 40 subjects in the control group (0.0498; α = 0.05). These results indicate an increased risk of neuropsychiatric illnesses such as attention deficit hyperactivity disorder (ADHD) in patients given propranolol for IH, as supporting evidence to previous claims.
