Older fathers are more likely than younger ones to have children with schizophrenia and autism, according to a new study released on Wednesday in the journal Nature. Researchers in Iceland have found that older fathers pass on more genetic mutations to their offspring, which can give rise to the two conditions. With each year they age, men are likely to develop as many as two new mutations that can be passed to their children. Analysts say the groundbreaking study could help explain the rise of autism spectrum disorder in the U.S., which has climbed steadily in recent decades and now affects 1 in 88 children.
