Brain problems can linger months after ICU stay
New york: Critically-ill people who end up spending days in an intensive care unit (ICU) often develop thinking and memory problems,according to a new study. Even when people recover from their physical illness,those problems can persist for more than a year after their hospital stay,researchers said. They found ICU patients who were delirious severely confused and unable to focus were especially likely to go on to have thinking and memory problems. Doctors have known for years that certain patients are prone to some degree of thinking problems after hospital procedures. What is new about this study is that cognitive problems were seen among patients with a wide range of illnesses. However,the people were alike in one way: they were all very sick.
