According to new research, new mothers are far more likely than others to report mild-to-moderate symptoms of obsessive-compulsive disorder (OCD) after childbirth. The study, published in the March/April issue of the Journal of Reproductive Medicine, found that 11 percent of women reported significant obsessive-compulsive symptoms at two weeks and six months after delivery, compared to the 2 to 3 percent of individuals in the general population diagnosed with OCD.

This, the first large-scale study of post-partum OCD, found that affected mothers reported classic signs of the disease – intrusive thoughts, compulsive behaviors, and fears and rituals related to the baby. Though the survey used self-reported data from 461 moms (329 of which provided information six-months after childbirth), none were clinically diagnosed with OCD. In more than half of the mothers, symptoms of OCD went away after six months.

Researchers posit that being obsessive and compulsive when caring for a newborn may actually be an appropriate psychological development, saying that problems only develop when the symptoms start interfering with the mother’s daily life.

About 70 percent of the women who had OCD symptoms also suffered from depression, supporting the idea that postpartum depression is its own disease, as the anxiety and obsessive symptoms are not typical for a major depressive episode.
A recent study provides insight into how obsessive compulsive disorder (OCD) develops. Led by Claire Gillan and Trevor Robbins at the University of Cambridge and Sanne de Wit at the University of Amsterdam, the study suggests that compulsive behavior may not be a response to obsessive fears, but instead may be a precursor to those fears (American Journal of Psychiatry, July 2011). That is, compulsions such as repetitive hand-washing may lead to an obsessive fear of germs—rather than the other way around.

“It has long been established that humans have a tendency to ‘fill in the gaps’ when it comes to behavior that cannot otherwise be logically explained,” said Gillan in a recent issue of Cambridge’s Research News. “In the case of OCD, the overwhelming urge to senselessly repeat a behavior might be enough to instill a very real obsessive fear in order to explain it.”

The study, which involved 20 patients suffering from OCD and 20 control subjects, measured patients’ tendency to develop habit-like behavior. Participants were required to learn simple associations among stimuli, behaviors, and outcomes in order to win points on a task. The researchers found that patients suffering from OCD were much more likely to continue to respond with a learned behavior, even when that behavior did not produce the desired outcome; that is, they quickly formed habits, or irresistible urges, to perform a task. These behaviors, initiated and observed in a laboratory setting and in the absence of any related obsessions, suggest that the compulsions themselves may be the critical feature of OCD.

This finding seems to support the approach of exposure and response prevention (ERP) as a treatment for OCD. ERP is a therapy that challenges patients to discontinue compulsive responding and learn that the feared consequence does not occur. Proponents of ERP say that once the compulsion is stopped, the obsession tends to diminish or disappear.
