Study: Married Couples Often Share Mental Health Patterns
Scientists looked at millions of married people in different countries to see if they had similar mental health problems.
They discovered that couples often share patterns of mental health issues, meaning if one person has a disorder, the other is more likely to have one too.
This happens because people tend to choose partners who are similar to them in many ways, including their mental health.
Also, couples who live together for a long time become more alike, and environmental factors can contribute to diagnoses.
The study shows that understanding how people choose their partners can help scientists study mental health disorders, genetics, and potential treatments.
Study found couples share patterns of psychiatric disorders across cultures and generations.
Data from over 14.8 million people in Taiwan, Denmark, and Sweden was analyzed.
Researchers examined nine psychiatric disorders, including schizophrenia, depression, and anxiety.
The study found non-random mating affects genetic studies of psychiatric disorders.
Children with both parents affected are twice as likely to develop the condition.
