Slide 2
Population: 1960 to 2050 (in millions)
WHY ARE THE ELDERLYAN IMPORTANT POPULATION?
• 20th century:<65-year-olds tripled>65-year-olds increased 11
• 35% of surgeries
• 20 million surgeries/year
• Present later for care
• More comorbidities
• Tend to need more emergent care

CORTICAL FUNCTIONS
• Level of consciousness• Orientation/perceptual ability• Memory• Attention/concentration• Language• Motor functions/praxis • Visuospatial skills• Executive function• Judgment/abstraction
Slide 5
WHAT IS DEMENTIA?
• Acquired syndrome of decline in 2 or more cognitive functions
• Decline in function from baseline
• Different from normal cognitive lapses; not due to delirium, psychiatric illness, or other medical diagnoses
• Not an inherent aspect of aging 1 in 10 persons aged 65+ have dementia 1 in 2 persons aged 85+ have dementia
Slide 6
CONSENSUS STATEMENT
First International Workshop on Anesthetics and Alzheimer’s Disease
• University of Pennsylvania, University of California at San Francisco, Harvard University, University of Wisconsin, University of Virginia, Columbia University, Mount Sinai School of Medicine
• May, 2008
• Interest in onset of Alzheimer’s and exposure to anesthetics
Slide 7
SCREENING FORCOGNITIVE DECLINE
• Mini-Cog 3-item recall
Clock drawing test
• MMSE
• Animal naming
• Digit span
• Orientation questions
Slide 8
DELIRIUM VS. DEMENTIA
• Delirium and dementia often occur together in older hospitalized patients
• The distinguishing signs of delirium are: Acute onset Cognitive fluctuations over hours or days Impaired consciousness and attention Altered sleep cycles
Slide 9
MORTALITY OF DELIRIUM
In medical units at YaleNew Haven Hospital:• Mortality of in-hospital delirium: 25%33%• Unrecognized by physicians in 30%50% of cases
Inouye et al. Am J Med. May 1999.Slide 10
POST-OP DELIRIUM (1 of 2)
• Incidence 10%15% after age 65
• Increases risk of mortality and longer hospital stay
• Numerous risk factors besides advanced age: Dementia Depression Anemia Alcohol and drug withdrawal Metabolic derangement Acute MI Infection Emergency surgery
Slide 11
POST-OP DELIRIUM (2 of 2)
Often due to:
• Medications
• Hypoxia
• Pain
• Infection
• Sleep deprivation

AVOID INPATIENT DELIRIUM!
• Orientation strategies
• Maintain day/night schedule
• Avoid restraints
• Avoid sedative/hypnotics
• Ensure assistive devices are working (eyes
and ears)
• Avoid immobility
• Avoid dehydration
