Summary

Story summary

A Copenhagen study shows brain serotonin activity, measured with Loudness Dependence of Auditory Evoked Potentials (LDAEP), predicts sexual side effects from SSRI antidepressants in 90 depressed patients.
Higher pretreatment serotonin activity correlated with a greater likelihood of sexual dysfunction, especially orgasm difficulty, at 87% accuracy.
The LDAEP test could help doctors tailor antidepressant prescriptions to minimize side effects.
Further research with a larger sample is planned to validate these findings.
