In a new study published Feb. 26 in JAMA, psychiatry researchers found a child born to a 45- year-old dad was 25 times more likely to have bipolar disorder, 13 times more likely to have ADHD, 3.5 times more likely to have autism, 2.5 times more likely to exhibit suicidal behavior or a substance abuse problem, and twice as likely to have a psychotic disorder like schizophrenia when compared to kids born to a 24-year-old father. That’s in addition to the increased risk for academic problems, low IQ scores and failing grades.
“We were shocked by the findings,” study author Dr. Brian D’Onofrio, an associate professor in the department of psychological and brain sciences at Indiana University Bloomington, said in a statement. His research team explained that men continue to produce new sperm throughout their lives, and each time they replicate, there’s a chance a DNA mutation might occur. Women meanwhile have a set number of eggs they are born with.
According to Dr. Harold Levinson, this fascinating study highlights the importance of genetic defects in determining a wide range of mental and behavioral disorders. And for the first time, male vs female aging factors were recognized.
