4. Wall Street Journal THE INFORMED PATIENT By LAURA LANDRO Hospitals Combat an Insidious Complication Delirium in ICU Patients, October 17, 2007; Page D1 “Gravely ill with pneumonia and sepsis, SBM was heavily sedated on a ventilator for 10 days in 2002. She suffered several complications in the ICU -- including delirium, a state of temporary confusion and disorientation that frequently occurs in critically ill patients. But after she returned to work, Ms. Miller, now 54 years old, was unable to concentrate or organize her thoughts. She had to retire early...”

5. Anecdote: Sepsis Patient 64 y/o female executive: Previously healthy Community-acquired pneumonia, sepsis ARDS and on vent for 10 days Had ICU delirium Lungs, heart, kidneys recovered without complications Head CT and MRI normal, neuro exam non-focal Debilitating “executive dysfunction” syndrome

6. Anecdote: Sepsis Patient 1 year follow-up letter Dear Doctor, you remember my sister, who is a 64 year old CEO with many employees. After she developed delirium, we couldn’t seem to get her mental clouding cleared for quite some time. She has tried to go back to work, and driving, and functioning although she can not seem to fully bounce back. I saw her for the first time about a month ago, when she came out for my daughter's Bat Mitzvah. She seems to have lost her "spark". She was such a personality pre-illness, so gregarious and really the life of the party. She is very flat now, and has memory problems. She doesn't remember anything about her illness or her hospitalization. Some long term, but mostly short term memory problems. She looks much older, and is walking very slowly, always holding onto railings, etc. She looks like a very elderly woman now. The illness really changed her. ref: Tremendous deterioration in cognitive and functional capacity (Kiely & Marcantonio, J Gerontol 2006;61:204-08)
