Thirty percent of adults with ADD report childhood physical abuse

March 6, 2014 by Michael Kennedy

(Medical Xpress)—Thirty percent of adults with Attention Deficit Disorder or Attention Deficit Hyperactivity Disorder (ADD/ADHD) report they were physically abused before they turned 18. This compares to seven per cent of those without ADD/ADHD who were physically abused before 18. The results were in a study published in this week's online Journal of Aggression, Maltreatment, and Trauma.

"This strong association between abuse and ADD/ADHD was not explained by differences in or other early adversities experienced by those who had been abused," says lead author Esme Fuller-Thomson, Professor and Sandra Rotman Chair at University of Toronto's Factor-Inwentash Faculty of Social Work. "Even after adjusting for different factors, those who reported being physically abused before age 18 had seven times the odds of ADD/ADHD."

Investigators examined a representative sample of 13,054 adults aged 18 and over in the 2005 Canadian Community Health Survey including 1,020 respondents who reported childhood physical abuse and 64 respondents who reported that they had been diagnosed by a health professional with either ADHD or ADD.

"Our data do not allow us to know the direction of the association. It is possible that the behaviors of children with ADD/ADHD increase parental stress and the likelihood of abuse," says co-author Rukshan Mehta, a graduate of the University of Toronto's Master of Social Work program. "Alternatively, some new literature suggests early childhood abuse may result in and/or exacerbate the risk of ADD/ADHD."

According to co-author Angela Valeo from Ryerson University, "This study underlines the importance of ADD/ADHD as a marker of abuse. With 30 per cent of adults with ADD/ADHD reporting childhood abuse, it is important that health professionals working with children with these disorders screen them for ."

Children who have ADHD likely also have parents with ADHD or genetically related disorder (ASD, BPD, Depression, Schizophrenia) and are probably on a neuro developmental disorder spectrum themselves, but never diagnosed or treated. People raised in households with abuse are themselves more likely to be abusive. All of these same disorders are known to have both genetic and environmental components, but the genes associated with these disorders are also rather common in the population. Epigenetics, cycles of abuse (exposure to "stress" if you follow the studies in mice)... there is your answer. Except it can't be wiped out in just one generation, unfortunately.
