A First-Rate Madness: Uncovering the Links Between Leadership and 
Mental Illness

 From the product description:

[T]he very qualities that mark those with mood disorders- realism, 
empathy, resilience, and creativity-also make for the best leaders in 
times of crisis.  ... Though sane people are better shepherds in good 
times, sanity can be a severe liability in moments of crisis.   ... 
[T]he most common types of insanity can confer vital benefits on 
individuals and society at large-however high the price for those who 
endure these illnesses."
