A condition where the behaviour of politicians, business leaders, and other people in power, changes for the worse as they come to enjoy increasing power and influence. The syndrome causes certain changes to the brains of these leaders which in turn makes them suffer from a number of undesirable qualities; including losing touch with reality, taking excessive pride in their actions, displaying lesser empathy towards other people, and taking arrogant decisions or actions without sufficient thought. The term was coined by former British Foreign Secretary David Owen, who has studied behavioural changes in various world leaders, in his 2007 book by the same name.
