The current debate on the Attention Deficit Hyperactivity Disorder (ADHD) subtypes focuses on determining whether the similarities and differences found between them support the evidence to conceptualize both subtypes as manifestations of different disorders. The objective of this ex post facto retrospective study is to investigate the differences between ADHD-predominantly inattentive type (ADHD-I) (n = 20) and ADHD-combined type (ADHD-C) (n = 39) in prenatal, perinatal and medical history. Results indicate that both subtypes present high number of obstetrical complications and medical problems. The ADHD-I has higher correlation with prenatal haemorrhages, ear infections and allergies, while lactate's colic and wounds that require stitches are associated with the ADHD-C. The main conclusion suggests that problems with an effect which would be more continuous in time have higher incidence in the ADHD-I, while several characteristics presented during the first year as well as wounds that require stitches are more likely to be observed in the ADHD-C. © International Journal of Clinical and Health Psychology.
