-more common in women
-time from onset to death typically 7-11 years
-death often secondary to dehydration or infection

-may have more implicit memory than originally thought

Q

Pathology of AD:

A

-affects the temporal and parietal lobes early on –> most of the cortex in most severe stages

-BETA-AMYLOID PLAQUES:
-proteins stick together and block synapse signaling
-proteins come together in clumps to form plaques that attach to the neuron
-microglia react to the plaque and an inflammatory response results

-NEUROFIBRILLARY TANGLES:
-show up inside neuron
-tau proteins are chemically changed at microtubules; normally they provide structural support for the microtubules
-disruption of “rail” system

Q

Genetic testing for Alzheimer’s Dementia

A

Apolipoprotein E gene (APOE) on
chromosome 19 removes beta amyloid
* APOE 4 allele is less effective at removing
beta amyloid, thus INC risk
* APOE 2 allele – is protective, thus DEC risk

  • Risk for AD by 85 years of age:
    • No APOE 4 allele, 9-20%
    • If one APOE 4 allele, 25-60%
    • If 2 APOE 4 allele, 50-90%

Chromosome 21 has a beta-amyloid precursor protein, thus producing amyloid–> worse prognosis

Q

What is delirium?

A

*PART OF DIFFERENTIAL DIAGNOSIS FOR DEMENTIA

A condition of severe confusion and rapid changes in brain function, not a disease but a cluster of symptoms that result from a disease or other clinical process

Often the result of treatable and therefore transient physical or mental illness

RAPID ONSET
-cognitive fluctuations over hours or days
-impaired consciousness and attention
-altered sleep cycles

24
Q

Normal Pressure Hydrocephalus (NPH) symptom triad:

A

*PART OF DIFFERENTIAL DIAGNOSIS FOR DEMENTIA

diff walking

decline in thinking

loss of bladder control

CAUSE: excess CSF accumulates in the brain’s ventricles–> may need shunt

25
Q

What three depression rating scales were discussed in class?

A

Geriatric Depression Scale

Cornell Scale for Depression in Dementia

Hamilton Rating Scale for Depression

26
Q

Max score and score ranges on MOCA:

A

visuospatial/executive
naming
memory
attention
language
abstraction
delayed recall
orientation

MAX SCORE: 30
26-30: normal range
27.4: average
22.1: MCI
6.2: AD

27
Q

MMSE categories and score:

A

less specific than MOCA

registration
attention and calculation
recall
language

TOTAL: 30
20-24: mild dementia
13-19: moderate dementia
<13: severe dementia

28
Q

What is a test for working memory:

A

digit span backward

29
Q

STROOP test:

A

The Stroop test can be used to measure a person’s selective attention capacity and skills, processing speed, and alongside other tests to evaluate overall executive processing abilities.

30
Q

What are the two primary medication types that are used for individuals with Alzheimer’s Disease?

A

AChE blocker –> AChE normally eats up acetylcholine, which is bad for individuals with AD, these drugs prevent that from happening so that Ach can continue to help neurons communicate

drugs that block glutamate
-glutamate in too much quantity can affect learning and memory poorly and neural tissue can be affected with too much–> drugs that block glutamate can help avoid killing the cell with overstimulation

31
Q

What are the 7 categories of the Global Deterioration Scale:

A

1-no cognitive decline
2-very mild cognitive decline (age-associated memory impairment)
3-mild cognitive decline (mild cognitive impairment)
4-moderate cognitive decline (mild dementia)
5-moderately severe cognitive decline (moderate dementia)
6-severe cognitive decline (moderately severe dementia)
7-very severe cognitive decline (severe dementia)

32
Q

THE GEMS MODEL -What are the different colors?

A

blue sapphire - true blue, no dementia

diamond - clear, sharp, rigid, doesn’t like change, stubborn, create the right setting and care

emerald- green–> go but not always sure where, words aren’t always clear, there are more flaws, struggling occasionally, may get lost with directions

amber - caution; caught in moment of time, no safety awareness, lacks patience, impulsive, behavior very different than past, invade spaces, take things, low or high sensory needs

ruby- STOP light, lost fine motor in eyes, fingers, mouth, feet, have strength but loss of skill, visual interpretation impaired, still have rhythm and music, hands are more gross movement than fine, can’t settle down and get started with a task

pearl- turns down reflexes, shuts down skills, with the right care you can still see the beauty of the gem, give them the right setting and the right care

33
Q

Physical activity recommendations for patients with dementia

A

leisure-time physical activity at midlife at least twice per week –> associated with reduced risk of dementia

PA may alter: Tau accumulation, synapse number, and function, restore neurogenesis, increase neurotrophin levels, positively alter inflammation and immunity, affect circadian rhythms, improve cognition

34
Q

Executive function tests:

A

trail-making test (set shifting)
verbal digits backward test (working memory)
Stroop colour-word test (response inhibition)

35
Q

what is declining cognition associated with?

A

increased number of falls

falls occur in approx 30% of clients with AD –> lack of perception of where their bodies are in space and their inability to move adequately around objects

-executive function plays an important role in balance control–> increasing cognitive impairment leads to decrease in balance

36
Q

balance gains after intervention may not be help after one month when the intervention is stopped

A

motor learning and dual task training

37
Q

Dual task cost definition:

A

represented in a decrement of motor and cognitive performances during dual tasks

Dual-task costs express performance changes as a percentage of each individual’s single-task performance. Positive values represent performance decrements under dual-task conditions, and negative values represent performance improvements.

38
Q

What type of feedback is recommended early in the progression of dementia?

A

external feedback

explicit memory strategies

39
Q

Dual tasking is recommended in what stage of dementia severity?

A

early stage

40
Q

Things to reduce in the middle stage of dementia severity

A
  • Reduce some cognitive challenges
  • Reduce some explicit memory strategies
  • Reduce some verbal instructions
  • Reduce verbal external feedback
    *Reduce dual tasking
41
Q

With regular exercise and home based caregiver support, there can be a delay in ____

A

institutionalization

42
Q

High intensity functional ex. program among older ppl with dementia (AD vs non-AD) living in nursing homes:

A

Supervised, group-based and individualized high-intensity exercise program is applicable in this population if we identify and alleviate limitations such as fear, pain, fatigue, etc.

43
Q

Recommendations for treatment of late stage dementia:

A

Physical Activity
* Exercise
* Mobility
* Fall Prevention
* Implicit Memory Use
* Demo instructions
* Manual Guidance
* Increase/Decrease arousal

A high-intensity functional exercise program for patients living in residential care facilities may:

A

inhibit AD progression and delay shrinkage of parts of the brain dedicated to memory

45
Q

RCT on regular exercise 1 hour 2x/week and how long were the gains maintained after study completion?

A

12 months after

max total of 56 points

52
Q

What happens to cognitive evaluation over time?

A

Eventually, continuing to evaluate cognition may not yield additional information and caregivers must adapt

53
Q

What is an example of a pain assessment for individuals with dementia?

A

pain assessment in impaired cognition (PAIC 15)

54
Q

What is one strategy that can help to improve movement and function in those with dementia?

A

identify stress triggers and remove them from the environment if possibel- example: background noise

55
Q

Cognitive stimulation program in individuals with AD

A
  • Enhances neuroplasticity
  • Reduces cognitive loss
  • Helps patients to stretch functional independence through better cognitive
    performance
  • Combine with behavioral management techniques can improve physical health
    and depression in individuals with AD
    —> behavioral management such as:
    -redirection: distraction or suggestion of alternative activities, reassuring tone, warm approach, smile, comfort

-validation: assist the person to feel acknowledged and understood, accept the reality of the person, use conversation to redirect

56
Q

Strategies from a study about an individualized exercise program for individuals with dementia:

A

STRENGTH BASED:

-keeping it short and simple
-external memory aids: visual aids, calendars
-learning by modeling
-allowing pts to choose the activity
-using familiar activities or hobbies in exercise
