with ADHD and multiple needs that will not be self evident if the diagnosis is just ADHD or just DCD." Before the Scandinavian studies, recognition that individuals with attention problems may also have difficulties with movement, perception, and memory had received little attention in studies. According to various studies, half of the children with ADHD also have DCD. With the development of the ADHD concept, the previous, less precise, category of Minimal Brain Dysfunction (MBD), "a term almost universally employed in child psychiatry and developmental paediatrics from the 1950s to the early 1980s" was replaced. Gillberg began to study DAMP in the late 1970s, when ADHD was still called MBD and the DAMP concept has been adjusted as the term ADHD was introduced and became internationally used. Around 1990, DAMP had become a generally accepted diagnostic concept in two Nordic countries, but when the DSM-IV appeared in 1994, DAMP became considered a redundant term in many countries, since DAMP is essentially equivalent to ADHD in combination with DCD as defined by DSM-IV. Gillberg's four criteria for DAMP are: ADHD as defined in DSM-IV; Developmental Coordination Disorder as defined in DSM-IV; Condition not better accounted for by cerebral palsy; and IQ higher than about 50 [Gillberg, 2003: box 1]. According to Gillberg, clinically severe form DAMP (or ADHD+DCD) affects about 1.5% of the general population of school age children; another few per cent are affected by more moderate variants. Boys are overrepresented; girls are currently probably underdiagnosed. There are many overlapping conditions, including conduct disorder, depression/anxiety, and academic failure. There is a strong link with autism spectrum disorders in severe DAMP. Familial factors and pre- and perinatal risk factors account for much of the variance. Psychosocial risk factors appear to increase the risk of marked psychiatric abnormality in DAMP. Outcome in early adult age was psychosocially poor in one study in almost 60% of unmedicated cases. About half of all cases with ADHD have DCD, and conversely, ADHD occurs in about half of all cases of DCD. Gillberg has published around 80 papers on DAMP, ADHD and related conditions. Legal case One of Gillberg's research projects, the Gothenburg study, has become the center of a heated controversy. The controversy concerns the question to what extent the Principle of Public Access, which in Sweden supports transparency in publicly funded activities, can be applied to sensitive data collected in medical studies involving human
