Dementia increases the risk of 30-day readmission to the hospital after discharge
(PHYSorg.com Medicine & Health)

About 25 percent of older adults admitted to hospitals have dementia and are at increased risk for serious problems like in-hospital falls and delirium (the medical term for an abrupt, rapid change in mental function). As a result, older adults with dementia are more likely to do poorly during hospital stays compared to older adults without dementia.
