Is there an association between perinatal complications and attention-deficit/hyperactivity disorder-inattentive type in children and adolescents?

Objective: The objective of the present study is to investigate the association between attention deficit/hyperactivity disorder (ADHD), predominantly inattentive type (ADHD-I) and prenatal, delivery and early postnatal complications (PDPC).

Method: In a case-control design, we assessed a sample of 124 children and adolescents with ADHD-I and 124 non-ADHD controls (6-17 years old) from both a non-referred (n = 200) and a clinical sample (n = 48). Cases and controls, matched by gender and age, were systematically evaluated through structured diagnostic interviews.

Response to methylphenidate in children and adolescents with ADHD: does comorbid anxiety disorders matters?

There are controversial evidence in the literature on the role of comorbid anxiety disorders (ANX) in the improvement of attention-deficit/hyperactivity disorder (ADHD) symptoms with methylphenidate (MPH) treatment. Our main objective was to assess differences in the response to MPH treatment in children and adolescents with ADHD with and without comorbid ANX. We extensively evaluated response to MPH in a naturalistic study of 280 children and adolescent with ADHD according to DSM-IV criteria.
