Researchers at Washington University School of Medicine in St. Louis have found what may be a behavioral marker for obsessive-compulsive disorder (OCD) risk.
Young children with tendencies toward perfectionism and excessive self-control were twice as likely as others to develop OCD by the time they reach their teens.
MRI brain scans showed that the perfectionists had differences in a brain structure previously linked to OCD in adults.
The findings are published July 18 in the journal JAMA Psychiatry. Having a lot of self-control and striving for perfection often are considered by parents and society as good because they can eliminate mistakes, but excessive self-control and perfectionism raise a red flag, said Kirsten E. Gilbert, PhD, the study’s first author and an instructor in child psychiatry at Washington University.
In adolescents and adults, these characteristics are associated with OCD and other disorders, such as anorexia and social anxiety. We’ve now been able to link this to OCD risk in children.
OCD is a chronic mental health disorder that often involves uncontrollable, recurring thoughts, or obsessions such as a fear of germs or a need to have things in perfect order and behaviors that a person feels the urge to repeat over and over such as hand-washing, compulsive counting or repeatedly checking on whether doors are locked.
Gilbert said it is important to identify the disorder as early as possible because the condition often is chronic and recurs throughout life.
If very young children at risk can be identified, it may be possible to intervene earlier to prevent or at least lessen the intensity of obsessions and compulsions linked to OCD.
The researchers enrolled 292 children ages 4 and 5. Over the next 12 years, 35 kids went on to develop OCD. Among children the researchers determined were exercising excessive self-control and perfectionism, an OCD diagnosis was twice as likely as among those who didn’t care as much about performing a task absolutely correctly.
All of the children in the study were recruited more than a decade ago for a related study in which researchers evaluated young children for depression. The data for the new study was culled from the previous study’s videotaped interactions of children with a researcher>
