“Postoperative delirium (POD) is frequently under diagnosed and more often than not, under treated. It is the final common manifestation of multiple neurotransmitter abnormalities; with features of impaired cognition, fluctuating consciousness and a disturbed sleep-awake cycle. At least 15% of elderly patients undergoing major procedures have POD, with an associated increase in mortality. Various risk factors and batteries of clinical examination have been devised to diagnose delirium, followed by a multifaceted approach to treatment, using biopsychological along with pharmacological intervention.”
