The exact cause of personality disorders is unclear. However, genetics, neurological differences, and environmental factors may contribute to the development of these complex mental health conditions.

Distinct psychiatric disorders have more in common biologically than previously believed, according to the largest and most detailed analysis to date of how genes influence mental illness. The study, ...

A massive global genetics study is reshaping how we understand mental illness—and why diagnoses so often pile up. By analyzing genetic data from more than six million people, researchers uncovered ...

Researchers have found that motor delay and low muscle tone were common signs of an underlying genetic diagnosis in children with neurodevelopment disorders. In a new study, UCLA Health researchers ...

At the genomic level, the researchers identified over 100 regions of the genome where genetic variants influence multiple disorders simultaneously. One region on chromosome 11 stood out as a "hotspot, ...

Psychiatric disorders can share common genetic influences, which means parts of DNA can be at the root of more than one mental condition, new research has found. The study, led by researchers at Texas ...

"It's a slow-moving train wreck," Mike Graglia says about his 12-year-old son Tony's rare genetic disease with no cure. Caused by a tiny fluke of nature—a mutation in a gene known as a SYNGAP1—the non ...

Researchers have uncovered shared genetic pathways that link multiple psychiatric disorders. These new findings have the potential to change the way psychiatric disorders are diagnosed and treated, ...
