Cognitive impairment + MMSE Flashcards
three key features of cognitive impairment
loss of higher brain function, loss of functional independence, signs of physical brain disease
What to look for in higher brain function
Look for change of higher brain functions
changes in behavior
does patient have identify changes?
does family/others see a change?
key features of loss of functional indepndence?
loss of skills ($ management, phone numbers, driving)
significant indicator for dementia
often need witness to provide info
w/ no significant functional decline, this could be mild cognitive impairment
signs of physical brain disease
Cognitive changes, loss of function and/or focal neurological deficits or CNS hyperactivity
imaging based on abnormalities of brain
Primary concerns with signs of physical brain diseasd (4d)
destructive of tissue (space occupying lesions)
Depression
Drugs
Delirium
what is the score cut off for the MMSE?
below 24 indicatives dementia or cognitive deficit
what score is of concern in the 6-item congitive impairment test (6CIT)?
> 7 is abnormal
____% of people over the age of 65 experience memory loss

Personality (eg. not being able to carry out conversation, complete ADLs, loss of sense of day/time/place)
Which 6 signs should prompt you to do a mental status exam?
- Loss of cognitive function (complaint from patient/informant)
- Difficulty getting details (taking history)
- Significant change in behaviour
- Un-kept appearance or loss of weight
- New-onset depression/anxiety/psychosis
- Confusion w/o an obvious cause
What is the most significant indicator of dementia?
Loss of functional independence (eg. inability to feed themselves, difficulty navigating society, difficulty with ADLs)
What tool can be used to measure a loss of functional independence?
Functional Independence Measure (FIM)
A patient with a decline in cognition and normal functional skill can be described as having ________________________________
Mild cognitive impairment (MCI)
