Two-thirds of patients sick enough to land in a hospital intensive care unit come away from the experience with substantial mental deficits, a new study has found.
The new research, which quantifies a phenomenon long observed by critical-care physicians, found that three months after leaving the hospital, 4 in 10 patients continue to have cognitive problems on a par with those seen in cases of moderate traumatic brain injury. And more than a quarter experience a decline in mental function akin to that seen in patients with mild Alzheimer’s disease, the study says.
For 58% of patients who’ve experienced a stay in the ICU, those intellectual deficits are still there a year after they have been released from the hospital, the study found. More.
