Why Some Breakups Feel Like Trauma

At a glance

Breakups can mimic trauma in the brain: Romantic breakups, especially those perceived as traumatic, triggered brain activity similar to that seen after physical or sexual assault.
Emotional intensity varies by breakup factors: Feelings of betrayal, not initiating the breakup, or lingering attachment were linked to stronger responses in emotion-related brain areas.
Heartbreak has real neurological impact: For some young adults, romantic loss activates trauma-related brain regions, underscoring the need to take emotional pain seriously.

A recent study published in the Journal of Affective Disorders has found that romantic breakups can trigger brain activity similar to that seen in people who’ve experienced physical or sexual assault, especially among emerging adults who perceive the breakup as traumatic.

Researchers observed heightened activity in the hippocampus and amygdala, areas involved in emotional memory and threat detection, when participants viewed breakup-related images, including photos of their actual ex-partners. This response varied based on specific breakup characteristics, such as who initiated the breakup or whether participants felt betrayed.

“RRDs [romantic relationship dissolutions] should be considered as potentially traumatic events. Breakup characteristics are risk factors for experiencing RRDs as traumatic,”

the study authors concluded.

The study involved 94 participants aged 18 to 25 who reported post-traumatic stress symptoms. Of these, 42 identified a breakup as their most traumatic experience, while others cited physical or sexual assault or another stressful event. During an fMRI scan, participants viewed a combination of neutral, positive, and trauma-related images. Breakup-related brain activity was comparable to that of individuals shown assault-related images, suggesting similar emotional processing.

The researchers also found that “greater hippocampal and amygdala activation was associated with being the person who did not initiate the breakup, feeling betrayed, or still holding positive thoughts about the ex-relationship.” Factors like attachment style, childhood neglect, and sexual orientation also influenced neural responses.

While the sample size was relatively small, the study highlights how intensely romantic loss can affect young adults, sometimes neurologically mirroring trauma. The authors note the need for more research but make a compelling case for recognising that, for some, heartbreak is more than just emotional; it’s biologically impactful too.
