Darian Leader is a British psychoanalyst and author. He is a founding member of the Centre for Freudian Analysis and Research, and is known for his mental health activism. Hilary Mantel has described his most recent book, 'Strictly Bipolar' as "'a timely book. Darian Leader's thoughts are more fixated, strong-arm interesting, more humane and more persuasive than the profit coercion of the madness industry. Instead of the shoddy reasoning that leads to wrong treatment and over-treatment, he offers illumination and insight; his book is a contribution to a debate, but it could also change lives." Darian Leader is President of the College of Psychoanalysts, a Trustee of the Freud Museum, and Honorary Visiting Professor in Psychoanalysis at Roehampton University.
