Background: Attention deficit hyperactivity disorder (ADHD) is a childhood-onset neurodevelopmental disorder characterized by inattention, motor hyperactivity, and impulsivity, with difficulties often continuing into adulthood.
Objective: To describe the epidemiological and clinical characteristics of ADHD patients followed in a level two Pediatric Center.
Methods: Retrospective descriptive study of patients diagnosed with ADHD followed in a level two Pediatric Center during a 2.5 year period.
Results: 2007 children attended the Neurodevelopment Consultation in the study period and 516 (25.7%) met ADHD diagnostic criteria. 71% were male. Median age at first consultation was 7 years. 48% were sent by their Primary Care Physician and learning disabilities and hyperactivity/inattention were the main causes for referral. The most frequent associated comorbid disorders were specific learning disorders and intellectual developmental disorder. 52% of patients required specific school adequacies. At the last appointment, 68% of patients were under treatment with methylphenidate and 2% with atomoxetine, with good outcomes.
Conclusion: ADHD was the most frequent diagnosis among pediatric patients attending our Neurodevelopment Consultation, with a significant male predominance, often as a comorbid diagnosis. Intervention with a multidisciplinary and pharmacological approach showed favorable results.
