The client's family is questioning the nurse about bipolar disorder. Which statements about the etiology of bipolar disorder do most psychoanalytical theories subscribe to? Select all that apply.

Psychoanalytical theory views bipolar disorder as a psychodynamic struggle between internal personality structures rather than purely biological factors. These theories emphasize unconscious conflicts where manic behaviors serve as a psychological ego defense mechanism to ward off intense feelings of worthlessness and intrapsychic pain. Rationale: A. The role of acetylcholine is a neurochemical hypothesis rather than a psychoanalytical one. Research into cholinergic transmission focuses on the biological imbalance of neurotransmitters, which contradicts the focus on childhood development and the unconscious mind found in psychoanalysis. B. Elevated norepinephrine levels are associated with the biological etiology of mood disorders. Psychoanalytical theories generally ignore biogenic amines, focusing instead on the symbolic meaning of behaviors and the internal dynamics of the personality components during a manic shift. C. In mania, the id is theorized to bypass the regulatory functions of the ego. This results in the hedonistic and impulsive behaviors seen in the client, as the primitive drives for immediate gratification are no longer restrained by reality-based or moral boundaries. D. Psychoanalysts describe mania as a denial of depression. The hyperactive and euphoric state acts as a defense mechanism to prevent the individual from experiencing the underlying psychological despair and low self-esteem that characterize the depressive phase of the illness.
