Infection-Associated Delirium in Older Adults

Research into infection-associated delirium in older adults shows how infections, autoimmune responses, and other immune-mediated processes can drive inflammation in the brain, potentially triggering or worsening neuropsychiatric or neurocognitive symptoms.

Delirium and urinary tract infections: A misattribution in older adults?

Authors: Hughes, C., & Smith, M.

Journal: Age and Ageing, 2007

DOI: 10.1093/ageing/afm115
