Spend enough time with someone and you start picking up their habits. You might steal their favorite slang, mirror their laugh, or even start looking weirdly alike in photos. According to a massive new study in Nature Human Behaviour<\/a>, the overlap can go much deeper than quirks. Couples are significantly more likely to share psychiatric disorders than random chance would predict.<\/p>\n

Researchers analyzed health data from over six million couples in Taiwan, Denmark, and Sweden. Across all three countries, partners were more likely to have conditions like depression, anxiety, ADHD, schizophrenia, OCD, bipolar disorder, anorexia, substance use issues, or autism. \u201cWe found that a majority of psychiatric disorders have consistent spousal correlations across nations and over generations,\u201d the researchers wrote.<\/p>\n

The pattern is known as spousal correlation, and it\u2019s usually studied in contexts like education level, political beliefs, or religion. With psychiatric conditions, the causes are a bit murkier. Part of it may be \u201cassortative mating\u201d\u2014choosing partners with traits similar to our own. <\/p>\n

Another part is the simple fact of sharing an environment for years, which can blur the line between nature and nurture. And then there\u2019s the reality that dating pools are limited. As the researchers put it, these three influences overlap, making it hard to tease apart the strongest driver.<\/p>\n

\"Couples<\/p>\n

Long-Term Partners Often Develop the Same Mental Health Struggles\u2014Here\u2019s Why<\/p>\n

Interestingly, the similarities weren\u2019t tied to cultural context. Despite differences in healthcare systems and social structures, the results were nearly identical across the three nations. \u201cSpousal resemblance within and between psychiatric disorder pairs is consistent across countries and persistent through generations, indicating a universal phenomenon,\u201d the team wrote.<\/p>\n

There are caveats. The study didn\u2019t account for whether people met before or after a diagnosis, and some conditions\u2014like OCD, bipolar disorder, and anorexia\u2014showed variation between countries. Still, the scale of the data makes the overall trend hard to ignore.<\/p>\n

The findings also cause concern for genetics. Many studies assume that people mate randomly, which helps scientists separate environmental and genetic risk factors. But if couples with psychiatric conditions are more likely to pair up, then kids born into those relationships may face compounded risks. <\/p>\n

\u201cGiven the ubiquitousness of spousal correlation, it is important to take non-random mating patterns into consideration when designing genetic studies of psychiatric disorders,\u201d the researchers wrote.<\/p>\n

Couples trade inside jokes and bad habits until they can\u2019t tell whose is whose. According to this study, the same may go for psychiatric disorders.<\/p>\n","protected":false},"excerpt":{"rendered":"Spend enough time with someone and you start picking up their habits.
