A new study indicates psychiatric illness could be triggered by abortion. However critics term it as an "post-abortion syndrome" tactic from the anti-abortion movement. Researchers found that 72% of women who terminated their pregnancies were more likely to be hospitalised for psychiatric problems in the first four years after their pregnancy than women who carried their pregnancies to term. The study also indicated that Women who had an abortion were nearly three times more likely to be admitted to hospital for mental health problems than women who delivered. But a strong opposition came from a professor of psychology at the University of California at Santa Barbara, who said psychiatric problems cause women who become pregnant to feel less capable of raising a child and to terminate their pregnancy, but the reverse may not be true.
