Q

Explicit (declarative) memory

A

Recollection of facts and events

Semantic memory: understanding of meanings, understandings, and conceptual facts of the word (episodic memory can inform semantic memory)
Episodic memory: Memory of autobiographical events and understanding how, where, and when it occurred

21
Q

Normal cognitive changes

A

Slower thought processes
Caution and hesitation
Difficulty with name-face recognition
Past recognition with prompting
Occasional word finding difficulty
Able to find misplaced items

22
Q

Abnormal cognitive changes

A

Thinking and actions are not the same
Problems with initiating tasks
Cannot place people
Past and present indistinguishable
Personality changes

23
Q

How can we optimize cognitive aging

A

Physical activity
Mentally stimulating activities that are novel, mentally challenging, or learning a new skill
Social engagement: regular contact with family and friends, participation in hobbies and leisure activities with others, and social support from external sources

24
Q

Subjective expression of illness

A

Individuals’ care needs and support will differ from person to person

25
Q

Environmental Press Model

A

Interactions between an individual’s abilities and the fit with their environment will determine performance

Lack of fit to the environment such as overstimulation or understimulation produce boredom, social isolation, apathy, symptoms of depression, and frustration

26
Q

Mild cognitive impairment

A

Transitional state between normal aging and pathological decline
Presents with an elevated risk of progression to Alzheimer’s Disease
Cognitive decline in complex attention, executive function, learning and memory, or language
Decline may be reported by individual, knowledgeable informant, or concern of clinician based on testing
ADLs are intact but require more effort

27
Q

Amnestic Mild Cognitive Impairment

A

Primarily affects memory and the individual may begin to forget information that they would previously have recalled

28
Q

Nonamnestic mild cognitive impairment

A

Affects thinking skills other than memory, including the ability to make decisions, judge time or sequence steps for complex tasks, or visual perception

29
Q

Intervention for mild cognitive impairment

A

Memory support systems such as notebooks, calendars, lists, apps with reminders
Physical exercise and active lifestyles
Multicomponent programs such as memory training, external aids, and stress reduction

30
Q

Progression to dementia

A

Preclinical: Before changes in cognition and everyday activities are detected

Mild cognitive impairment leading to Alzheimer’s Disease: Cognitive symptoms emerge but function is still relatively unimpaired
- Not everyone with MCI develops AD

Alzheimer’s Disease: Day to day function is impaired

31
Q

Dementia

A

Multiple cognitive and intellectual deficiencies and decline involving memory, problems with language, impairment of motor skills, inability to recognize familiar people or objects, and impairments in planning, organizing, and abstract reasoning

32
Q

Memory change in dementia

A

Individuals will first lose memory of higher order IADLs and then BADLs
Working memory is affected first which leads to difficulties recalling new information and using it
Semantic memory is more stable but later stages of disease will impact ability to recall nouns, verbs, and names
Procedural memory is most durable

33
Q

Types of dementia

A

Lewy Body
Vascular
Frontotemporal dementia
Alzheimer’s Disease

34
Q

Lewy Body Dementia

A

Young onset (50-55 years)
Affects 50% of patients with Parkinson’s Disease
Progressive and gradually worsening

Symptoms
- Falling
- Rigidity
- Difficulty swallowing
- Incontinence
- Parkinson’s like symptoms (shuffling gait, tremors, rigidity, flat affect)
- Auditory or visual hallucinations
- Fluctuating cognition with variable attention and alertness

35
Q

Vascular dementia

A

Caused by stroke, uncontrolled hypertension, heart diseases, diabetes, peripheral vascular disease, smoking or genetics
Sudden onset

Symptoms (vary based on part of brain affected)
- Emotional and energy changes
- Cognition changes: Decrease in judgment, memory, disorientation, and word-finding
- Variable and inconsistent behavior

36
Q

Symptoms of frontotemporal dementia

A

Affect/personality changes
Rude and mean behavior
Language loss

37
Q

Alzheimer’s Disease

A

Progressive neurodegenerative disease characterized by loss of function and death of nerve cells in several areas of the brain
No known cure
Most common form of dementia

38
Q

Cause of Alzheimer’s Disease

A

Age (65+, risk doubles every 5 years)
Family history
Genetics

39
Q

Diagnosis of Alzheimer’s Disease

A

Rule out any other potential causes of confusion such as medication, hearing or vision loss, depression, alcohol, thyroid problems, UTIs, vitamin deficiency, or delerium
Physical and medical history
Blood work
Neurological exam
Medication review
CT scan, MRI, PET scan, spinal fluid test of plaque and tangle proteins
Neuropsychological testing

40
Q

Intervention for Alzheimer’s Disease

A

Medication
Address safety (environment), cognitive functioning, functional mobility, self care, caregiver coping and support, and behavioral management
Compensatory environmental modifications
- Remove clutter
- add signs
- Adaptive equipment that helps and does not involve new learning
Involve caregivers
Cover mirrors in bathrooms in later stages
Use old learning proverbs, songs, and memories

41
Q

OT clinical strategies for Alzheimer’s Disease

A

Address cognitive processes while actively participating in occupational performance
Practice and rehearse
Relate to previous knowledge
Present information directly
Make interventions fun and interesting
Decrease distractions
Consider habits and timing of activities
Utilize as many senses as you can
Make interventions relaxing
Break down tasks

42
