Besides, delirium is a common condition associated with adverse outcomes, including increase in morbidity, mortality, and need of health services utilization. Even though the etiology of cognitive impairment is multifactorial, drugs also are known to be an important cause of delirium. In this study, we present a patient manifesting a bisoprolol-induced acute delirium, for whom the delirium symptoms completely disappear after bisoprolol was ceased. Bisoprolol is widely used in cardiology for the treatment of hypertension and arrhythmia. Beta-blocking agents have been recognized for some time to have central nervous system effects, which could adversely cause common psychiatric syndromes.eninfo:eu-repo/semantics/closedAccessAtrial FibrillationBisoprololDeliriumArticle1819295Q4WOS:000352641100016Q4
