Genetic and environmental factors associated with delirium severity in older adults with dementia.
To determine (1) whether delirium severity was associated with Apolipoprotein E (APOE) genotype status and occupational complexity, a measure of cognitive reserve, in individuals with delirium superimposed on dementia; and (2) whether decline in delirium severity was associated with these same factors over a post-acute care (PAC) stay. ⋯ Individual differences, including genetic factors and level of cognitive reserve, contribute to the severity of delirium in older adults with dementia.
