Why does “Lao Lai Zi” grow up prone to depression?
According to the US MSNBC website reported on September 1, Swedish researchers have found that children born to middle-aged and older men are more likely to develop bipolar disorder when they grow up, and are more likely to become depressed and manic.
The study was published in the September issue of the Archives of Popular Psychiatry.
Researchers at the Karolinska Institute in Sweden analysed Swedish national demographics, including 13,428 people with bipolar disorder born between 1932 and 1991.
They found that people who were over 40 years old at birth were more likely to develop bipolar disorder when they grew up, and children born to fathers 55 and older were most likely to get the disease.
Compared with children born to fathers in their 20s, children born to middle-aged and elderly people are 37% more likely to suffer from bipolar disorder.
Not only that, the risk of these children doubling before the age of 20.
This “early-onset disease” is most closely linked to heredity.
Bipolar disorder can lead to severe mood swings. The peak age of onset is 15-19 years, and the first time is a depressive episode, and then the manic symptoms will appear.
The prevalence of this disease is 1% -4%, and 5 million people in the United States suffer from it.
The scientific community has generally agreed that the age and health of mothers have a major impact on newborn defects and other abnormalities.
But more and more evidence shows that the influence of fathers cannot be ignored.
Some studies have also found that the older a father is, the higher the risk of schizophrenia and autism in children.
Researchers believe that this may be related to the higher the age of men, the higher the possibility of sperm mutation.
However, Emma who led the research?
Frans pointed out that due to the low incidence of bipolar disorder, middle-aged and elderly men need not be afraid of becoming fathers.
