A newly released Pentagon report from 2008 claims Russian President Vladimir Putin has Asperger's syndrome, "which affects all of his decisions," according to USA Today.
The report, which was obtained by the news outlet, was created by a Pentagon think tank and theorizes that Putin's "neurological development was significantly interrupted in infancy."
The report was written by Brenda Connors, an expert in movement pattern analysis at the U.S. Naval War College in Newport, R.I., according to USA Today.
Connors reportedly wrote that studies of Putin's movements show he "carries a neurological abnormality."
Asperger's syndrome is a form of autism marked by difficulties in social interaction and nonverbal communication.
The 2008 report acknowledges the suspected diagnosis cannot be confirmed because researchers were not able to perform a brain scan on Putin.
The study was conducted by Connors and her colleagues, contractors for an internal Pentagon think tank known as the Office of Net Assessment (ONA).
USA Today reports that it obtained the study through a Freedom of Information Act request.
