Love Addiction & Heartbreak

Biomarker research has identified measurable differences in stress hormone profiles and dopamine sensitivity in people with addictive attachment patterns: elevated baseline cortisol, blunted oxytocin response to non-romantic social bonding, and altered dopamine receptor density. These biological signatures exist on a spectrum, not as a binary disease/non-disease distinction. The challenge now is translating lab biomarkers into clinical utility—determining what cortisol level or dopamine profile actually warrants intervention versus normal attachment variation.
