Addiction Linked to Disruption of ‘Love Hormone’

Addiction Linked to Disruption of ‘Love Hormone’New research from Australia links addictive behavior, such as drug and alcohol abuse, to the poor development of oxytocin, known as the “love hormone,” in early childhood.

“We know that newborn babies already have levels of oxytocin in their bodies, and this helps to create the all-important bond between a mother and her child,” said Dr. Femke Buisman-Pijlman from the University of Adelaide’s School of Medical Sciences.

“But our oxytocin systems aren’t fully developed when we’re born — they don’t finish developing until the age of three, which means our systems are potentially subject to a range of influences, both external and internal.”

Buisman-Pijlman, who has a background in both addiction studies and family studies, noted the main factors affecting our oxytocin systems are genetics, gender, and environment.

“You can’t change the genes you’re born with, but environmental factors play a substantial role in the development of the oxytocin system until our systems are fully developed,” she said.

“Previous research has shown that there is a high degree of variability in people’s oxytocin levels. We’re interested in how and why people have such differences in oxytocin, and what we can do about it to have a beneficial impact on people’s health and wellbeing.”

For her study, Buisman-Pijlman reviewed worldwide research into oxytocin, known as the “love hormone” or “bonding drug” because of its role in enhancing social interactions, maternal behavior, and partnership.

“Some of those studies show that some risk factors for drug addiction already exist at four years of age,” she said.

“And because the hardware of the oxytocin system finishes developing in our bodies at around age three, this could be a critical window to study,” she said. “Oxytocin can reduce the pleasure of drugs and feeling of stress, but only if the system develops well.”

Her theory is that adversity in early life is key to the impaired development of the oxytocin system.

“This adversity could take the form of a difficult birth, disturbed bonding or abuse, deprivation, or severe infection, to name just a few factors,” she said.

“Understanding what occurs with the oxytocin system during the first few years of life could help us to unravel this aspect of addictive behavior and use that knowledge for treatment and prevention.”

The study was published in the journal Pharmacology, Biochemistry and Behavior.
