Antidepressant drugs, already known to cause sexual side effects, may also suppress the basic human emotions of love and romance. That SSRIs, or selective serotonin reuptake inhibitors — the most common type of antidepressant — cause sexual dysfunction is common knowledge. Of the 31 million adults in the United States who take the SSRIs, about 30 percent are believed to experience sexual dysfunction.
But a new theory suggests that SSRI antidepressants may also subtly alter the fundamental chemistry of love and romance, snuffing the first sparks between two people otherwise destined to become lovers, and preventing couples from bonding.
"There's every reason to think SSRIs blunt your ability to fall and stay in love," said Helen Fisher, a Rutgers University biological anthropologist who has pioneered the modern science of love.
For some people, of course, sexual side effects are an acceptable price to pay for curing debilitating depression. But as antidepressant use becomes more common, extending beyond full-blown clinical depression to disorders like anxiety and, in some cases, insomnia, the possibility of love-stunting is troubling.
SSRI antidepressants work by boosting circulating levels of serotonin, a mood-regulating neurotransmitter that also inhibits desire. The drugs also decrease dopamine, a neurotransmitter involved in a wide range of cognitive and behavioral processes, among them desire and arousal. The new research suggests that dopamine may also play a part in romance.
During sex, a cocktail of hormones is released that appears to play important roles in fostering romantic attachment within the brain. Take away sex, and romantic love can dwindle. But this is just part of the problem, say Fisher and University of Virginia psychiatrist James Thomson.
Dopamine also appears central to the neurobiology of romantic love and attachment, conditions that Fisher believes to be affected by — but ultimately distinct from — sexual love and its effects. She and Thomson say that SSRIs may do more than cause sexual dysfunction: They also suppress romance. READ MORE.
