As people age, surgery becomes a greater risk to their overall health than the same surgery would be for younger people. Older people often have less robust immune systems so they are more at risk for general infections and they are more at risk for pneumonia. However, one of the most frightening risks for older people is post-surgical delirium. Delirium is described as an acute state of confusion that often affects older adults following surgery or serious illness. A recent study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) has found that inflammation most likely plays a key role in the onset on-set of delirium.
