A Pentagon study from 2008 claimed that Russian President Vladimir Putin has Asperger's syndrome, giving him a need to exert "extreme control" when faced with crises, according to the report released on February 5, 2015. Experts studying his movements and facial expressions in video footage theorized Putin's neurological development was disrupted in infancy, giving him a sense of physical imbalance and a discomfort with social interaction, according to the report by the Pentagon's internal think tank, the Office of Net Assessment.
