Mental abilities decline sooner than thought

A Swedish psychology study shows a person's mental capabilities begin deteriorating much earlier than scientists had previously suspected. In a study of more than 2,000 women showing very early signs of labor, doctors gave half of them intravenous Epsom salt and the other half a placebo infusion. Those given the Epsom salt cut their babies risk for cerebral palsy by 45 percent.

One-third of all cases of cerebral palsy are linked to premature birth.
