Oxytocin's Role in Improving Empathy in Borderline Personality Disorder

This episode delves into a new study exploring the use of oxytocin as a potential treatment for Borderline Personality Disorder (BPD), a condition for which there is currently no specific medication, relying primarily on Dialectical Behavior Therapy (DBT). Dr. Tracey Marks highlights that individuals with BPD often struggle significantly in relationships, characterized by mistrust, fear of abandonment, anxiety, depressed mood, impulsivity, and self-harming behaviors. A central hypothesis discussed is that impaired empathy may lie at the core of these interpersonal difficulties, driving many of the disorder's manifestations.

The podcast details a German study that investigated three aspects of empathy—cognitive, emotional, and approach motivation—in women with and without BPD. Participants were shown pictures of people expressing emotions, and their ability to recognize, relate to, and desire social closeness with these individuals was measured. Initially, women with BPD scored lower across all three empathy measures compared to the control group, although they showed a better ability to recognize negative emotions, likely due to their more frequent experience with such states. The study then administered a single dose of oxytocin via nasal spray to a subset of both groups. Dr. Marks illustrates oxytocin's powerful role in social bonding and emotional connection with a personal anecdote, where her protective thoughts for a vulnerable man instantly triggered her breastfeeding letdown reflex, demonstrating the hormone's rapid and profound influence on emotional responses.

The study's significant finding was that women with BPD who received the oxytocin nasal spray showed improvements in their empathy scores, reaching levels comparable to those of the untreated non-BPD group. This included an enhanced ability to relate to both negative and positive emotions and an increased desire for social closeness, mirroring Dr. Marks' own experience of wanting to protect the sales associate. This positive outcome suggests that oxytocin could be a valuable add-on agent in future clinical trials for BPD therapy, potentially addressing a biological component that makes it challenging for individuals with BPD to navigate social interactions and emotional understanding on their own.

While the study offers promising insights into a biological mechanism, Dr. Marks emphasizes that medication cannot replace the essential skills taught in therapy, such as managing emotions, tolerating distress, and improving relationships. The drug is seen as potentially filling a biological gap, making therapeutic work more accessible. The discussion also broadens to acknowledge that empathy deficits are not exclusive to BPD, being present in other disorders like Narcissistic Personality Disorder, suggesting a wider potential application for such interventions, starting with focused research in specific areas.

"To date, we really don't have a medication treatment for the disorder."

"Some researchers believe that at the core of the disorder is impaired empathy, and that this is what causes the interpersonal problems."

"The women with BPD scored low on all three measures compared to the group of women without BPD..."

"Oxytocin is a hormone produced primarily in your brain, and it has a number of functions, but the main ones are social bonding, childbirth, and breast milk production."

"Oxytocin plays a role in recognizing and interpreting facial expressions and feeling close to people. Some people call it the love hormone."

"But it fascinated me just how my thoughts of wanting to protect him triggered oxytocin release, and it was instant, within seconds of the thoughts, and here my body was preparing me to nurse this man."

"The women with BPD who got one dose of oxytocin nasal spray had rises in their empathy scores that was equal to the women without BPD who didn't get any treatment."

"A drug can't teach you those things, but this study adds weight to the idea that biologically there's something missing in people with BPD that makes it hard for you to do these things on your own."

"If you're lacking empathy, it stands to reason that you're going to have problems misinterpreting people's intentions or meeting someone else's needs because you have trouble relating to what the needs are."

"This was studied in borderline personality disorder, but problems with empathy is present in other disorders like narcissistic personality disorder."
