Could guide personalized treatment. Researchers from Copenhagen University Hospital have identified a potential brain test that predicts which patients taking antidepressants may experience antidepressant side effects, including difficulty achieving orgasm. The findings were presented at the European College of Neuropsychopharmacology (ECNP) conference in Amsterdam. The study focused on patients with depression treated with selective serotonin reuptake inhibitors (SSRIs), a common class of antidepressants that includes drugs such as Prozac and escitalopram. These medications can improve mood but are known to cause antidepressant side effects like sexual dysfunction in up to 70 percent of users.
