The study aimed to investigate whether involvement in a stable romantic partnership is associated with differences in peripheral brain-derived neurotrophic factor (BDNF) levels. In a cross-sectional study, 60 healthy adults (32 women; mean age 27.4 ± 4.1 years) were classified as in a stable relationship ( Participants in a relationship showed higher PLT-BDNF (4.36 ± 1.22 vs 2.85 ± 0.67 ng/mg; t(58) = 5.90, Our results would indicate that a stable romantic partnership is associated with higher intraplatelet and serum BDNF levels. These findings support an association between current committed romantic relationship status and peripheral BDNF measures in healthy adults. Show less
