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

Dementia is a…
• Degeneration of the brain cells
- Slow and steady decline over months to years
- Gradual or step-wise changes common
• Terminal illness

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

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
![Page 10: Your Role in Dementia Detection and Treatment](https://reader030.vdocuments.us/reader030/viewer/2022012715/61adab2423bfee79a94855e5/html5/thumbnails/10.jpg)
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)

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

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
![Page 13: Your Role in Dementia Detection and Treatment](https://reader030.vdocuments.us/reader030/viewer/2022012715/61adab2423bfee79a94855e5/html5/thumbnails/13.jpg)
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

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?

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

Registration
• Ask the patient to remember 3 words:
APPLE, TABLE, PENNY

• Ask patient to: remember the three words and say you will
ask for the three words later

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”

• Dementia is common and often missed
• Dementia can present differently depending on the underlying
disease
• Screening is important
• Think team work & communication (SBAR)!
• Think Mini-Cog!
