Neurocognitive deficits persist in up to 75% of ICU patients 6-12 months after ICU discharge and presumably may be higher in ICU patients who develop delirium (30). Cognitive deficits are global (31-33), including deficits in processing speed, memory, and attention. (31) Hopkins concludes that the most consistent deficit across studies is decreased memory. (30) This pattern of deficits, as well as the consistent findings of impaired social and occupational functioning in ICU survivors (32, 34) suggests impaired executive function. Executive function refers to the capacity to plan, initiate, organize, inhibit, and monitor thought and behavior. It is a pattern of impairment which is thought to represent diffuse frontal lobe damage. Executive function is typically poorly assessed in medically ill patients and yet has potentially substantial impact on overall functioning. Functional incapacity includes everyday issues such as difficulty buying groceries, keeping appointments or adhering to medication regimens. (34, 35) For geriatric patients treated in the ICU, only 3% have normal post-ICU functional capacity. (36) It remains unclear if there is a change in anxiety and depressive symptoms among patients who develop delirium and those that do not.
