An Unquiet Mind by Kay R. Jamison (1997, Paperback)

For anyone who has a family member or loved one who suffers with Bi-Polar disorder this is a must read. Ms. Jamison herself is a Psychologist and Bi-Polar. She has written a very clear and understandible explanation of this disorder: how behaviors are effected, how thought processes can be different from normal, possible and likely triggers for mood changes and how medication effects the disorder.

Having a son with Bi-Polar disorder and many many discussions with Doctors and Psychologists, this book painted a very clear picture of the challenge.
