5

Delirium

• Disturbance in consciousness with reduced ability to sustain attention & cognition
• Develops over short period of time and fluctuates
Caused by a medical condition: Dehydration, drug toxicity, blood pressure changes, blood sugar changes, anesthesia REVERSIBLE

6

DSM criteria:

Must have memory impairment and at least one of the following:
– Aphasia: Difficulty speaking
– Apraxia: Difficulty with motor planning
– Agnosia: Difficulty recognizing objects
– Disturbance in executive functioning: Planning, problem solving, sequencing…

7

Early onset

before age 65

8

Most common form dementia

Alzheimer 60-80% Progressive, degenerative disease of brain tissue

9

Stage 1: Alzheimer

Very mild to mild cognitive deficits (1-3 years)
Angry outbursts, personality changes, denial , preference for familiar settings
Memory loss, greater for recent events
Decline complex cognitive tasks, decision making, planning, attention, initiation

10

Stage II: Alzheimer

Mild to moderate decline (5-7 years)
Questioning, wandering, pacing, rummaging
Chronic recent memory loss, difficulty with written and spoken language
Needs assist with ADL’s more difficulty with familiar tasks

11

Stage III:Alzheimer

moderate to moderately severe decline (2-3 years)
Repititious movement or sounds
Misidentificaiton of familiar objects, decreased vocab need HOH assis
ADL dependent, incontinence, diff eating, impaired gait increase falls

12

Stage IV: Alzheimer

Severe cognitive deficits & physical decline (average 3 months- 1 year)Terminal stage, fleeting attention, may respond to touch or music
Utters vs. saying words, decreased visual tracking, contracture/skin integrity
Bed or w/c dependent, TOT dependent in self-care, dysphasia, loss of appetite

13

Need to evaluate:Person with dementia,

Cognition, orientation, safety awareness, visual perceptual abilities, Hearing, touch, strength, ROM, Functioning in daily activities, The caregiver(s), Medications, routines, The contexts, Home assessment, fall risk, supports and barriers leads to memory loss and problems

14

Structural changes Alzheimer

Beta amyloid plaques Twisted strands tau protein (tangles) Nerve cell damage and death Acetylcholine (ACh) transmission reduction/Reduction of AChR
• Secondary dementia

15

2nd most common dementia

Vascular dementia 20-30% of cases Multi infarct/post CVA

16

Post CVA

Confusion, disorientation, global aphasia, vision loss

17

Multi infarct (small strokes or vascular issues)

Gradual changes as damage accumulates
– Impaired planning , attention, problem solving and judgment, emotional lability, word finding deficits, impaired social functioning

18

Dementia with Lewy Bodies

(usually seen with PD) Structural changes
Abnormal aggregations of protein alpha-synuclein Disrupts dopamine projections to frontal cortex and basal ganglia Dementia/cognitive decline Parkinsonian motor disturbances Shuffling gait, tremor, mask like appearance, rigidity, flexed posturing

19

Frontotemporal dementia

Group of disorders caused by progressive cell degeneration in frontal and/or temporal lobes 10-15% all cases Diagnosed earlier ages (50’s to 60’s) Family history ALS

20

Sub-types:-Behavioral Variant (bvFTD)-

Primary Progressive Aphasia-
FTD Movement Disorders
Corticobasal degeneration
Progressive supranuclear palsy

21

FTD Symptoms:

• Behavioral changes often earliest symptom
• Deficits in spatial orientation
• Speech deficits: word finding, increased generalized speech, difficulties with written expression.
• Hallucinations and delusions uncommon

22

Secondary to other medical conditions

Creutzfeldt-Jakob Disease: transmissible spongiform encephalopathy caused by abnormal proteins (prions), rapidly fatal.
Wernicke-Korsakoff Syndrome: Severe B-1 deficiency. Most common cause ETOH abuse, creates chronic memory dysfunction.
Huntington’s Disease progression
Parkinson’s Disease progression
HIV/AIDS Related
Medication induced dementia Symptoms persist when substance is withdrawn, 12% of persons diagnosed with dementia,
Result of: Substance abuse, Medication, Toxic exposure

23

Aggressive behaviors

Hitting, biting, screaming, pacing
Strategies: Be calm, stay out of reach, redirect

24

Hallucinations and delusions

Auditory, tactile, visual, olfactory
Most common involve theft or spouse (unfaithful or imposter) Strategies: Distraction

25

“Sundowner’s Syndrome” or “Sundowning”

Agitation, confusion, wandering and/or disorientation at end of day Strategies: Picture schedule for day/night routine, Improve lighting during day, Physical touch, Redirect, Find activities of interest, Social interaction, Provide structured routine, Temperature control

26

Repetitive actions

Pacing, rummaging, repeating, gestures, self abusive behaviors, disruptive/irritating to carers Strategies: Engage in other activities – folding trash bags, holding teddy bear/doll, rocking chairs, music, modify familiar and enjoyed ax

27

Catastrophic reactions

Extreme outburst to minor stressors -Verbal/physical aggression or social isolation -May be brought on by fatigue (ill, tired)Strategies: Redirect Know triggers Take out of environment Be calm Predictable/no surprises Short naps Read cues

28

Impaired Verbal abilities

Difficulty with using nouns, Rely more on nonverbal gestures and sounds, Can sing familiar songs, may revert to primary language Strategies: Speak slowly and calmly, Use simple, short sentences, Clearly enunciate words, Write short phrases/words, Ask yes/no questions, Minimize distractions, Allow extra time, Listen for true meaning, Use positive words, Do not use baby talk

29

OT Scope of practice

-Educate family members and those in the early stages of disease about dementia and its functional effects.
- Evaluate persons with dementia to determine strengths, impairments, and performance areas needing assistance.
- Assist person with dementia to improve function through compensation or adaptation.
- Assist caregivers to help them cope with difficult, and yet often rewarding, role.
Observation of functional tasks Assessment Need to evaluate: Cognition, orientation, safety awareness, visual perceptual abilities Hearing, touch, strength, ROM Functioning in daily activities
The caregiver(s) Medications, routines
The contexts Home assessment, fall risk, supports and barriers

30

Dementia assesments

MMSE/MoCA,
Kitchen Task Assessment (replaced by Rabideau),
Executive Function Performance Test,
Allen Cognitive Level,
Cleveland Scales for ADL,
Katz ADL,
Disability Assessment for Dementia,
Independent Living Scales,
Caregiver’s Strain Questionnaire

31

Interventions: Health promotion

Maintain strengths of clients Promoting wellness care providers

32

Interventions: Remediation

Physical skills (ROM, Strength, Endurance)

33

Interventions: Maintenance

Provide supports to ensure skills are maintained as long as possible

34

Interventions: Modification

Safe and supportive environments through adaptation and compensation

35

Interventions: Spaced retrieval

Procedural memory over declarative memory Compensation strategies for memory ie: Repetition priming and external aids

36

Interventions: Behavioral functional analysis

A: antecedent B: Behavior to change C: Resulting consequence

37

Reminiscence therapy

Discussion of past events, activities, and experiences with person or group

38

Tangible prompts:

photographs, familiar items, music and archive recordings.

39

Barriers for wandering behavior

Wallpaper doors Stop signs/caution tape (recognizable warning signs) Enclose outdoor areas

40

Safety

Home modifications/fall prevention DME, contrasting colors Lock doors and cabinets Medications, sharps

41

ADL

42

Toileting

Place picture of toilet on bathroom door Extra set of incontinence pads/clothing for community Establish routine: Same time every day, limit caffeine in evening.

43

Feeding/eating

Watch for eating non edibles Quiet and distraction free environment
Social environment (may mimic others eating) Use color contrasting plates for table/table cloths No plastic utensils – could bite/breakOffer finger foods, sippy cups, straws

44

Bathing

Plan for best part of day Warm up room ahead of time Hand-held shower/ over head can be scary Offer choice bath or shower
