Kay Redfield Jamison is a clinical psychologist with a rare insight. She is a world leader in the study of bipolar (manic-depressive) illness, a condition that she herself has had since adolescence. As a highly regarded clinician with direct experience of the illness she treats, she has a special perspective on the debilitating nature of this psychiatric disorder and its seductive but disastrous highs, depressions and disordered thinking. She tells A.C.Grayling and an audience at Wellcome Collection in London about mania, creativity and the best medicine for an extraordinary condition. Show less
