Children who lose a parent before the age of 3 are 84% more likely to experience psychosis as adults, according to research published in the British Journal of Psychiatry. In a dose-dependent relationship, the increased risk for children aged 3 to 7 drops to 47%, and 32% for children aged 7 to 13. Data was drawn from nearly 947,000 children born in Sweden between 1973 and 1985.
