- Genetics: family history of dementia, PDD, cardiovascular disease, stroke, presence of ApoE4 allele on chromosome 19
- Environment: head injury, alcohol abuse

- Environment: head injury, alcohol abuse
In addition to disruptions in cognition, dementias are commonly associated with
changes in function, ________, __________
mood, and behavior.
The most common forms of progressive dementia are ___, VaD, DLB, and FTD; the
pathophysiology for each is poorly understood.
AD
Clinicians are advised to be alert for _____________________________ in older adults to detect dementia and dementia-like presentation in early stages
cognitive and functional decline
Dementia assessment
Cognitive parameters
1. __________ : person, place, time
2. _________ : ability to register, retain, recall information
3. _________ : ability to attend and concentrate on stimuli
4. Thinking: ability to organize and communicate ideas
5. Language: ability to receive and express a message
6. Praxis: ability to direct and coordinate movements
7. Executive function: ability to abstract, plan, sequence, and use feedback to guide
performance

[Dementia] Mini-Cog combines the CDT with the ________________
three-word recall.
The caregiver of the patient with dementia often has as many _______ as the patient with dementia, so a detailed assessment of the caregiver and the caregiving environment is essential.
needs
[Dementia] Avoid the use of physical and pharmacological ___________.
restraints
[Dementia] Maximize __________ capacity: Maintain mobility and encourage independence as long as possible, provide graded assistance as needed with ADL and IADL, provide scheduled toileting and prompted voiding to reduce urinary incontinence, encourage an exercise routine that expends energy and promotes fatigue at bedtime, and establish bedtime routine and rituals
functional
[Dementia] Assure a therapeutic and safe environment: Provide an environment that is modestly stimulating, avoiding overstimulation, which can cause _________ and increase confusion
agitation
[Dementia] Provide appropriate _____ care in the terminal phase: provide comfort measures, including adequate pain management; weigh the benefits/risks of the use of aggressive treatment (tube feeding, antibiotic therapy).
EOL
[Dementia] Provide __________ education and support: Respect family systems/dynamics and avoid making judgments
caregiver
[Dementia] Patient outcomes: The patient remains ___________ and functional in the environment of choice for as long as possible, the comorbid conditions the patient may experience are well managed, and the distressing symptoms that may occur at EOL are minimized or controlled adequately.
independent
Delirium is a neurocognitive disorder that develops over a short period of time (hours to days), fluctuates in severity throughout the day, and is primarily a disturbance of __________ .
Delirium is a physiological consequence of another underlying disorder
attention
Delirium Outcomes: in hospitalized older adults
increased mortality, hospital length of stay, transfer to long-term care facilities, depression, decreased functional and cognitive status, increased geriatric syndrome complications, and dementia.

Delirium - ____ % of ICU patients
31
Delirium - 26% to 62% of __________ care patients
palliative
Delirium - Risk factors: in acute hospital units
dementia, older age, comorbid illness, severity of medical illness, infection, “high-risk”
medication use, postoperative status, diminished activities of daily living, immobility, sensory impairment, urinary catheterization, urea and electrolyte imbalance, metabolic acidosis, and malnutrition
Other possible risk factors include sleep deprivation, polypharmacy, physical restraints, and anemia

Delirium Assess for common and other risk factors
Postoperative status
High-risk medication use (e.g., benzodiazepines)
Urinary catheterization
Physical restraints
Postoperative status
High-risk medication use (e.g., benzodiazepines)
Urinary catheterization
Physical restraints
Assess for delirium
Key features of delirium (CAM, CAM-ICU, bCAM)

* Inattention
* Disorganized thinking
* Altered level of consciousness
Delirium symptoms (Nu-DESC)
* Disorientation
* Inappropriate behavior
* Inappropriate communication
* Illusions or hallucinations
* Psychomotor hypoactivity

Delirium - therapeutic environment
Foster orientation: Frequently reassure and reorient patient
Provide appropriate sensory stimulation: quiet room, adequate light, pursue one task at a time, use noise-reduction strategies.
Facilitate sleep
Foster familiarity
Maximize mobility
Reassure and educate family
Consult with a geriatric specialist.
Consider psychotropic medication as a last resort for agitation
