Neuropsychological disorders are frequently associated with obstructive ventilatory disorders (OVD).
Aim: To analyze the incidence of neuropsychological disorders in Brazilian children with OVD, using a screening questionnaire and to compare the answers given before and after surgery.
Patients and methods: We studied 30 children with clinical diagnosis of OVD. The children were divided into 3 groups: group I, children aged 4 to 7; group II, from 8 to 10; and group III, children over 11. The applied questionnaires were answered by the parents or tutors, and comprised 30 questions, 10 for each disorder: attention deficit, hyperactivity and impulsivity. The children were diagnosed with one of the disorders when presented 3 or more positive answers. The follow up interview occurred 6 months after adenotonsillectomy.
Results: There was a predominance of male gender (60.6%) over female gender (39.4%). Group II presented the highest number of significant changes, with reductions raging from 87.5% to 33.3% of patients with attention deficit, 75% to 50% of the hyperactive patients, and 50% to 33% of the impulsive patients.
Conclusion: There was neuropsychological improvement after the surgery, which occurred mainly in the children from group II. More interaction among health professionals is necessary when diagnosing and following up similar cases.
