Two weeks after their first Botox injections, 40 women took an average of about one-quarter of a second longer to read sentences describing angry and sad situations than they did immediately before the procedure, Havas and his colleagues found.
Critically, Botox patients show no decline in the speed with which they read sentences about happy situations, Havas’ team reports in an upcoming Psychological Science.
“These findings suggest that facial expressions are involved in assessing specific emotions or emotional situations,” Havas says.
Havas hypothesizes that Botox-induced paralysis of the frown muscle — which runs across the forehead just above the eyes, allowing it to pull the eyebrows inward and down — may gradually weaken brain circuits that coordinate negative emotions.
A 2009 fMRI study, led by German neurologist Andreas Hennenlotter, supports that idea. Women attempting to mimic images of angry and sad facial expressions displayed weaker activity in emotion-related brain areas two weeks after receiving Botox injections to the frown muscle, Hennenlotter’s group found.
Banishing frown lines with Botox can indeed have social repercussions, remarks psychologist Nicolas Vermeulen of Catholic University of Louvain in Belgium. Previous studies indicate that mimicry of facial expressions critically aids in understanding others’ emotions, intentions and behaviors, he points out.
“Botox patients who are interacting with others behind a locked face might be at risk to react in the wrong way to, say, an angry driver or an angry customer in a pub,” Vermeulen says.

The study, published Monday in the journal Obstetrics & Gynecology, is the largest to date examining the effectiveness of acupuncture to treat depression in pregnant women. It was funded by a grant from the government's Agency for Healthcare Research and Quality. "Acupuncture that we have tested works for pregnant, depressed women," said Rachel Manber, a study author and professor at Stanford University. However, "no single study is enough to make policy recommendations," she said.
Depression in pregnancy is a risk factor for postpartum depression. Postpartum depression is associated in some studies with poorer cognitive and emotional development in children. Some have linked depression in pregnancy and low birth weight.
As many as 14% of pregnant women are thought to develop a significant depression at some point during their pregnancy, according to the study authors, comparable to numbers who suffer from postpartum depression. Antidepressants are generally considered safe for use in pregnancy, but research has been limited and concerns continue to grow, according to the National Institute of Mental Health. One study showed that the risk of persistent pulmonary hypertension, a potentially serious lung condition, is significantly greater in newborns whose mother took antidepressants later in pregnancy. The Food and Drug Administration recommends that patients and physicians "carefully consider and discuss together" the benefits and risks taking antidepressants during pregnancy."Antidepressants are not an attractive option for many women," said Dr. Manber. "Many women are concerned about using antidepressant medication during pregnancy."
