Cognitive and Psychological Issues Flashcards
What is executive function?
Higher order cognitive skills
- sequencing
- self awareness
- planning
- organizing
- evaluating
Cognitive flexibility
- knowing how to adapt to situations
Decision making
- financial (are you getting a good deal, forward planning)
Ability to regulate emotion
Feedback utilization
Self perception
Standardized test for cognitive issues
MMSE
- Not sensitive to address the suitable changes associated with aging
- EF more of a predictor of function
3 approaches to assess executive function
Neuropsychological approach: relationship between impaired brain areas and behavior
- MRI’s other “hard” diagnostic tools
Cognitive approach: focus on specific cognitive process that make up EF
- Don’t usually have a baseline, so how do we know?
Functional approach
- Kettle Test
- Multiple Errand Test
What is metacognition?
Knowing what you know and what you don’t know
Self awareness of your intellect
What is the MMSE?
The MMSE consists of 11 simple questions or tasks grouped into 7 cognitive domains:
1) Orientation to time
2) Orientation to place
3) Registration of three words
4) Attention and calculation
5) Recall of three words
6) Language
7) Visual construction
Levels of impairment have been classified as:
None: score = 24-30
Mild: score = 18-24
Severe: score = 0-17

3 approaches to EF intervention
- Cognitive
- Exercise
- Social Engagement
Cognitive intervention for EF
Think, “If you don’t use it, you loose it”
Several studies looked at video games that required (Tetris, Rise of Nations, Cooking task)
- Problem solving
- Memory
- Sequencing
- Shifting attention
They all saw an increase in cognitive skills (per standardized testing) in as little as 4-6 weeks
However, the link to actual FUNCTION is very weak AND how long does the effect last is uncertain
These studies were virtual (video game), but it is likely the same could be accomplished through real life tasks (occupations)
Exercise interventions for EF
Connection between physical ability and cognitions
Multiple studies have shown that with increase physical activity and exercise, cognition improves
Most effective time line is 31-45 min sessions 3-5 times per week
Correlation between walking speed decline and cognitive decline
Social engagement interventions for EF
Idea that elderly clients who are socially engaged maintain or improve cognitive function
Problem based learning
Fits well with OT interventions because it is more function based
- Plan a fundraiser
- Bible study
- Volunteer at school
- Pickle ball
Functional, occupation-based tasks provide the vehicle for improving cognition
Why do we see a decline in cognitive ability with aging?
Multiple reasons
- changes in technology
- culture
- removed from experience
Benign cognitive decline: typical and mild
- ARCD: Age Related Cognitive Decline
Malignant Cognitive decline: atypical, disease or disorder driven
Types of dementia
Alzheimer’s
Vascular
Lewy body
Frontotemporal
Huntington’s
Mixed
Medication induced
CVA, TBI
Characteristics of alzheimer’s
Slow progression
No disturbance of consciousness
No other disorders or medication that may cause the symptoms
Symptoms don’t go away
Hallucinations in late stages
Must have impairment in at least 2 of the following areas:
- memory

- praxis (apraxia)
- recognition (agnosia)
- executive function (impaired judgement)

- highly susceptible to infections like pneumonia
Stage 1 Alzheimer’s
Normal behavior with no impairment
No noticeable symptoms or problems
Stage 2 Alzheimer’s
Very mild decline or changes
Minor memory problems may appear, like forgetfulness, which may also be due to normal aging
Stage 3 Alzheimer’s
Mild decline
Mild cognitive and physical impairments may become noticeable, like cognitive problems, decreased attention, and memory
Stage 4 Alzheimer’s
Moderate decline
May experience impairment in the ability to perform daily tasks
Stage 5 Alzheimer’s
Moderately severe decline
Symptoms may become moderate to severe, the pt may require help and support from caregivers in daily activities
Stage 6 Alzheimer’s
Severe decline
May need continuous supervision with basic tasks, like wearing clothes or eating
Stage 7 Alzheimer’s
Very severe decline
May lose ability to communicate and may need constant assistance
OT role with moderate stage Alzheimer’s

Lewy body dementia
Often confused with Alzheimer’s
Caused by a build up of lewy body proteins in the brain which can be definitively diagnosed
Memory vs attention and visual perceptions
Much wider swings of “bad days”
- Episodes of extreme confusion
- Zoning out
Early stage lewy body
Delusions
Restlessness
REM sleep disorder
Movement difficulties
Urinary issues
Middle stage lewy body

- heart disease
Symptoms:
- confusion and agitation
- unsteady gait
- memory problems
- urinary issues
- night wandering
- decline in ability to organize thoughts/actions

- sensory: smelling familiar scents, touching distinctive textures
Trail Making Test
Involves visual scanning and working memory. The TMT has two parts; the TMT-A (rote memory) and TMT-B (executive functioning)
If the person cannot complete the test in 5 minutes, the test is discontinued. An average score for TMT-A is 29 seconds and a deficient score is greater than 78 seconds. For TMT-B, an average score is 75 seconds and a deficient score is greater than 273 seconds.
Difference between sign and symptom
Symptom: what the patient reports (subjective)
Sign: can be objectively measured; hard neurological signs
