Chapter 26: Bipolar Disorders in Mental Health Care

Bipolar Disorders in Mental Health Care details the diagnostic criteria for Bipolar I, which requires at least one full manic episode, and Bipolar II, characterized by hypomanic states and major depression without the intensity of a full manic peak. The text also covers cyclothymic disorder, a chronic but less severe oscillation between low-level depression and mild elation. From a biological perspective, the chapter explores the roles of neurotransmitter imbalances, particularly involving dopamine and norepinephrine, genetic predispositions with high twin concordance, and cellular dysfunctions such as ion regulation issues within the sodium-potassium pump. Psychosocial theories are also examined, suggesting that mania may serve as a psychological shield against underlying depressive states. Clinical manifestations are discussed thoroughly, highlighting pressured speech, racing thoughts, and impaired judgment that often lead to professional and interpersonal devastation. Nursing management is a core focus, emphasizing the need for a therapeutic relationship defined by a neutral, matter-of-fact communication style, firm limit-setting to handle manipulative behaviors, and the maintenance of a low-stimulus environment. Pharmacological interventions include mood stabilizers like lithium, which requires careful blood monitoring, and anticonvulsants such as divalproex sodium, alongside atypical antipsychotics. The chapter concludes with strategies for managing co-occurring substance use disorders, improving medication adherence, and utilizing assessment tools like the Young Mania Rating Scale to measure symptom severity.
