MENTAL HEALTH AND LEADERSHIP

Dr. Nassir Ghaemi, psychiatrist, published a book about the links between leadership capacities and the mental health ("A first rate madness").
His thesis is that in times of crisis it might be possible that an excess of "normality" may hinder the special leadership skills required.
I still didn't read the book but in the meantime we can have a hint by reading his blog:
