Kay Redfield Jamison’s An Unquiet Mind is a memoir of bipolar disorder written by a clinical psychologist, professor of psychiatry and mood-disorders researcher. In this text, Jamison publicly described her own experience of mania, depression, psychosis, suicidality and lithium. We believe that this book remains a useful training text in psychiatry for three core reasons: what it reveals about treatment refusal, about professional stigma attached to psychiatric illness within medicine, and about the things that syndromic diagnosis can miss. Read critically, An Unquiet Mind remains helpful for thinking about ambivalence, clinician stigma, shared decision-making, and the limits of diagnosis without abandoning clinical precision.
