What Is Dementia?
Dementia is “an acquired
syndrome of decline in at least
two cognitive domains, sufficient
to affect daily life in an alert
patient”

Dementia is a…
• Geriatric syndrome
• General name for a group of diseases that share similar signs and
symptoms
- Patients can act differently depending on the type of dementia
» Behavior or language may be worse than memory
2015, 2011 Sarah Hallen, MD and contributors
Dementia is a…
• Degeneration of the brain cells
- Slow and steady decline over months to years
- Gradual or step-wise changes common
• Terminal illness
2015, 2011 Sarah Hallen, MD and contributors
Dementia diagnosis
• Clinical diagnosis
- Patient history
- Cognitive testing
- Physical exam & diagnostic tests
» Evaluates for things other than dementia that cause cognitive problems
▪ Stroke
▪ Vitamin deficiencies
▪ Infectious diseases
2015, 2011 Sarah Hallen, MD and contributors
Risk Factors for Dementia
• Age
• Family history
• Genetics
• Low education level
• Cardiovascular disease
• Head trauma and traumatic
brain injury (TBI)
• History of delirium
• Mild cognitive impairment
2015, 2011 Sarah Hallen, MD and contributors
Mild Cognitive Impairment (MCI)
• Impairment in cognition without impairment of function
• 10-15% of MCI patients may convert to dementia each year
• Monitor over time

Dementia is NOT Delirium
• Delirium is a sudden change in cognition with
- Fluctuation
- Inattention
- Disorganized thinking and/or
- Changes in level of activity
• Dementia is a slow progressive change
2015, 2011 Sarah Hallen, MD and contributors
Dementia is NOT Delirium
• Dementia and delirium are related
- Patients with delirium are at increased risk of dementia
- Patients with dementia are at increased risk of delirium
• Relationship more complex than one causing the other…
- May share a common etiology (e.g. hypotension; acute
illness)
2015, 2011 Sarah Hallen, MD and contributors
Dementia is NOT Depression
• Depression can affect mood and cognition like dementia
• Cognitive changes due to depression may improve with
treatment
• Can be hard to distinguish between dementia and
depression - especially if apathy is present
- Symptom onset and functional history can help
2015, 2011 Sarah Hallen, MD and contributors
Dementia is NOT Normal Aging
• As people age, it is common to have:
- Increased difficulty with multi-tasking
- Occasional forgetfulness
• Normal aging does not affect daily function
2015, 2011 Sarah Hallen, MD and contributors
Alzheimer’s Disease (AD)
• The most common type of
dementia
- >50% of people with dementia have AD
- 6th leading cause of death in the United
States
» 5th for those > 65 years of age

2015, 2011 Sarah Hallen, MD and contributors
Dementia: Unrecognized & Untreated
• > 50% of people with dementia have not been diagnosed1-3
- Typical AD patient has symptoms for 2–6 years prior to diagnosis
- Most patients diagnosed at the moderate stage of illness2
• Only 35% of people with AD have received treatment4

ANYONE Can Suspect Dementia
• ASK YOURSELF:
- Are the changes observed new?
- How long have they had the symptoms?
- Could they normally manage their household and self-care at baseline?
- Are they missing appointments? Medications?
- Do they seem confused when they call the office?
- Have you noticed differences in dress or behavior?
2015, 2011 Sarah Hallen, MD and contributors
ANYONE Can Suspect Dementia • Delirium: changes are new (hours to days)
- Perform the Confusion Assessment Method (CAM) questions
- Notify a provider
- Delirium can indicate a medical emergency
• Dementia: changes are not new (months to years)
• Dementia can be difficult to diagnose in the hospital
setting
2015, 2011 Sarah Hallen, MD and contributors
Mini-Cog
• Dementia screening test
• Administered in 3 minutes
• No special equipment required
• Sensitive (76-99%) and specific (89-93%)
• Effective for diverse socioeconomic status and education

Mini-Cog
1) Registration
2) Clock draw test
3) Three word recall
2015, 2011 Sarah Hallen, MD and contributors
Registration
• Ask the patient to remember 3 words:
APPLE, TABLE, PENNY
• If they can’t repeat all 3 – say them all again
• Ask patient to: remember the three words and say you will
ask for the three words later
2015, 2011 Sarah Hallen, MD and contributors
Clock Draw (CDT)
• Give the patient a pre-drawn
circle
• Ask them to place the numbers
so they “look like the face of a
clock”
• Ask them to “draw the hands of
the clock so it reads ten past
eleven”
2015, 2011 Sarah Hallen, MD and contributors
Scoring the Mini-Cog
Clock
• Numbers present and in the right sequence
• Hands joining in the center of the clock
• Short hand pointing to the 11
• Long hand pointing to the 2
Recall
• Must remember all 3 words

If the Mini-Cog is Positive,
You need to ACT
• A positive screen does NOT mean the patient has dementia –
only that further evaluation is necessary
• Communicate concerns to other team members
• Consider any safety concerns that you may be able to address
2015, 2011 Sarah Hallen, MD and contributors
Who Makes Up The Team?
• Family and visitors
• CNAs
• Social Workers
• Pharmacists
• Care Coordinators
• Transport
• Sitters
• Chaplain
• Rehabilitation Services
• Dieticians

etc. may be appropriate
- Consider brain imaging
- Consider neurology referral or referral for neuropsychological testing or geriatric
assessment
2015, 2011 Sarah Hallen, MD and contributors
Role of Provider • In the hospital, new dementia = tentative diagnosis
• Consider trial of anti-dementia medications
- May wish to defer until outpatient when at medical/cognitive baseline
- Discuss and anticipate common safety issues with patient/caregiver, including
medication adherence, risk of financial exploitation, home safety hazards,
driving, etc.
- Refer to local and national agencies for education and patient/caregiver support
