Schizophrenia Risk May Start in Womb

Over the past several decades, a steady stream of studies has documented that people born in winter and spring have an increased risk for schizophrenia, a serious mental illness characterized by disordered thinking, hallucinations and other psychotic symptoms.
Explanations for the increased risk have ranged from the astrological -- different signs of the zodiac have been associated with various mental problems -- to accounts that suggested the risk came from seasonal variations in sunlight.
In recent months and years, scientists have developed a different explanation: Studies show the increased risk of schizophrenia appears linked to maternal infections during the first and second trimesters of pregnancy -- especially flu infections. Since the flu peaks in the fall, this might explain why babies born in the winter and spring have the higher risk.

A Local Example of Advocacy (Post Dispatch Story)

"What's really disturbing is it's the one form of mental retardation birth defect that is 100 percent preventable," says Melinda M. Ohlemiller, director of prevention and advocacy for St. Louis Arc, an agency that advocates for people with birth defects. So the fight against fetal alcohol syndrome can be won without compromise, Ohlemiller says. That's why health experts have increased their warnings about drinking while pregnant. Even that one glass of red wine at night or a couple of beers on the weekend can have consequences for your unborn child, says Dr. Mark Mengel, professor of family and community medicine at St. Louis University School of Medicine.
