The author, Professor of Psychiatry at Johns Hopkins University School of Medicine, is an authority on manic depressive illness. With this powerful, well-written memoir she "came out of the closet," publicly declaring that she herself had suffered from manic depressive illness for years. Jamison describes the manifestations of her illness, her initial denial and resistance to treatment with medication, attempted suicide, and her struggle to maintain an active professional and satisfying personal life.The author was "intensely emotional as a child," (p.4) and in high school first experienced "a light lovely tincture of true mania" (p.37) during which she felt marvelous, but following which she was unable to concentrate or comprehend, felt exhausted, preoccupied with death, and frightened. (pp. 36-40) Interested in medicine as an adolescent, she pursued her goal in spite of mood swings and periods of mental paralysis. Jamison completed graduate work in clinical psychology; shortly after obtaining a faculty appointment "I was manic beyond recognition and just beginning a long, costly personal war against a medication that I would, in a few year’s time, be strongly encouraging others to take [lithium]." (p. 4)Jamison eventually, through strong support from friends and colleagues, excellent psychiatric care, and her own acceptance of illness, has been able to reach a state of relative equilibrium--tolerable levels of medication (fewer side effects) and dampened mood swings. But she makes clear that she must stay on lithium and remain vigilant.
