- The changes are so strong they can even influence a man’s grandchildren
- They make the offspring more prone to conditions like bipolar disorder
The children of people who have experienced extremely traumatic events are more likely to develop mental health problems.
And new research shows this is because experiencing trauma leads to changes in the sperm.
These changes can cause a man’s children to develop bipolar disorder and are so strong they can even influence the man’s grandchildren.
Psychologists have long known that traumatic experiences can induce behavioural disorders that are passed down from one generation to the next.
However, they are only just beginning to understand how this happens.
Researchers at the University of Zurich and ETH Zurich now think they have come one step closer to understanding how the effects of traumas can be passed down the generations.
