Bipolar disorder, previously known as manic depression, is estimated to affect more than 1 in 45 adults and is characterised by episodes of pathological mood states. The two poles are mania (with a predominant elated or irritable mood) and depression (with feelings of sadness, anxiety, guilt or hopelessness), but mixed states, with both mania and depression, frequently occur. Psychotic symptoms such as delusions and hallucinations are also frequent. The condition is associated with significant societal and personal burden, and can damage mental and physical health, relationships, careers and quality of life.<BR><BR>Both the diagnosis and management of bipolar disorder are difficult, even for mental health professionals. This practical guide therefore provides an overview of the disorder and detailed guidance for treating various aspects of the illness throughout its stages, from authors internationally renowned for their work in bipolar disorder. Also reviewed are theories of aetiopathogenesis and key clinical trials, as well as chapters devoted to psychosocial treatments, quality of life, substance misuse and insights from the `lived experience'. in-depth analyses of selected population groups, including youth, the elderly and women, complement clinical approaches to managing bipolar disorder.<BR><BR>Comprehensive and detailed, this guide will prove invaluable to clinicians, general practitioners, psychiatrists, psychiatric nurses and psychologists.
