A big study looked at how smart someone is and how much school they had affects their mental health later in life. Researchers gathered data from over 272, 000 Norwegian men. When these men were around 18, they took intelligence tests. Then, when they were between 36 and 40, the researchers checked their medical records for any mental health problems.

The results showed that men with higher IQs were less likely to have mental health issues as adults. This was true for most conditions, except bipolar disorder. Even when comparing brothers from the same family, the link between intelligence and mental health remained strong. This means that growing up in the same home didn't explain the connection.

Education also played a significant role. Men with more schooling had better mental health. However, the impact of intelligence on mental health was much stronger for men with less education. This suggests that men who are smart but didn't get much schooling might be at higher risk for mental health problems.

The study highlights that both brainpower and education are crucial for mental well-being. It also points to a group that might need more support: smart men who didn't finish much school. Helping these men could be a key way to prevent mental health issues.

This study is important because it shows that mental health is not just about genes or upbringing. It also depends on how smart someone is and how much education they get. This could help doctors and policymakers create better ways to support mental health.
