Objectives

Identify at least 3 signs or symptoms of cognitive impairment in the early, middle and late stages of dementia;

Identify at lesat 3 cognitive domains other than memory that may be impaired in older adults with dementia;

Understand the potential effects of impairment in various cognitive domains on behavior and everyday function in older adults with dementia;

Appreciate the resources needed to care for older adults with behavioral changes, disability and activity limitation.

What cognitive changes do we see in persons with dementia?

Deficits in one or more cognitive domains:

—learning and memory (amnesia)

—language (aphasia)

—perceptual-motor

• visual recognition (agnosia)

• performing motor activities (apraxia)

—executive function (abulia, apathy)

—complex attention (distractability)

—social cognition (lack of insight)

Consequences of Cognitive Impairment

Cognitive impairment can interfere with Communication

— Comprehension

— Ability to report symptoms, express needs Social awareness, self-monitoring Ability to follow directions Self-care (basic ADLs) Household management (instrumental ADLs)

Impairment in Activities of Daily Living (ADLs)

Instrumental ADLs (Household Management)

— Shopping

— Cooking

— Cleaning

— Laundering

— Using Telephone

— Paying Bills

Basic ADLs (Personal Care)

— Bathing

— Hygiene

— Grooming

— Dressing

— Feeding

— Toileting

Other Consequences

Cognitive impairment can interfere with Personal safety

— Eating (e.g. risk of choking or aspiration)

— Walking (e.g. risk of getting lost, falling)

— Household tasks (e.g. risk of fires, accidents)

Receipt of medical and nursing care

— Patient participation

— Delivery of care by providers & caregivers

Recognition of Cognitive Impairment

Suspect a neurocognitive disorder when person has self-care deficits person has difficulty following instructions family has “taken over” responsibilities person doesn’t participate well in medical,

nursing care, or rehabilitative care behaviors interfere with safety or care delivery

Don’t blame “old age”

What are the signs and symptoms of cognitive impairment ?

SIGNS are what we observe in these individuals

— Objective

SYMPTOMS are what the individual experiences

— Subjective

Impaired Memory and Learning (amnesia)

Forgetfulness

— Repetitious statements

— Misplacing things

— Missing appointments

— Leaving bills unpaid

— Inability to recall recent events

Disorientation

— Getting lost

Impaired Language (aphasia)

Trouble comprehending spoken or written language

— Inability to follow simple directions

Word-finding difficulty

— Hesitant speech

— Paraphasias (word substitutions)

— Anomia (loss of name recall); substitutes general terms and pronouns

— Circumlocutions (“talking around”)

— Neologisms (non-sense words or sounds)

Perseveration (repetitious speech, echolalia, palilalia)

Impaired Perceptual-Motor Function

Agnosia

— Inability to recognize faces, family members

— Trouble navigating in familiar environs

Apraxia

— Difficulty manipulating objects (e.g., opening package, unscrewing lid, buttoning, using zipper)

— Inability to assemble objects, perform spatial tasks (e.g., sewing, carpentry, dressing)

Impaired Complex Attention

Distracted by multiple stimuli

Can’t scan and focus on relevant stimuli or objects in environment

Can’t register information just given

Thinking and processing speed is slower

Can’t perform mental calculations

Impaired Executive Function

Loss of frontal lobe function:Lack of will or initiative (abulia, apathy)

Difficulty with reasoning and decisions

Inability to organize and plan activities

Inability to perform sequential tasks

Poor task completion

Inability to shift between concepts / tasks

Impaired social cognition

Loss of insight

— Lack of awareness of own situation

— Inability to appreciate safety concerns

Insensitivity to other persons’ mental state

— Inability to recognize social cues or read facial expressions

Disinhibition

Impaired judgment

Common Presentations:Early and Middle Stages of Dementia

Visual complaints Trouble following directions Difficulty performing familiar tasks Family members take over usual roles Loss of initiative

— Disengagement from usual activities

— Self-neglect

— Weight loss Diminished social spontaneity

— Less conversation

Common Psychological Changes:Early and Middle Stages of Dementia

Depression

— Apathy, withdrawal

— Sad or flat affect Anxiety

— Fear of being alone Paranoia

— Delusions about “imposters”

— Accusations of infidelity, theft Personality changes

Loss of Cognition and Function in Late-Stage Dementia

Aphasia: single words, echolalia, palilalia, mutism

Apraxia:

—Manual: inability to hold or manipulate objects

—Oral: difficulty chewing & swallowing

—Gait: instability, loss of ambulatory ability

Incontinent of bladder and bowel Terminal stages: inability to sit up, smile,

hold up head; bedbound Total dependence in basic ADLs

How does memory impairment lead to inability to perform basic ADLs?

Example

Patient is able to dress himself, but can’t remember where his clothes are kept

Walks outside naked

How does apraxia lead to difficulty with basic ADLs?

Example

Patient is continent of bladder, but cannot unzip or unbutton to pull down her pants

Wets her clothing

How does language impairment (aphasia) interfere with care?

Example

Patient who can’t verbally communicate that pills are hard to swallow

Spits medication at caregiver

How does visual agnosia lead to changes in behavior and function?

Example

Patient can maneuver to pull down his pants, but can’t recognize that a toilet is a receptacle for urination

Urinates on living room floor

Common Caregiver Misattributions

Laziness Dependency Belligerence Depression

Misattributions can lead to caregiver distress (frustration, anger, anxiety, depression) and increased risk of elder abuse

Initial approach to assessment, management, and prevention

Recognize

areas of impaired cognitive function

and

areas of preserved cognitive function

Help compensate for impairment

Support residual abilities

What other factors interact with cognitive deficits, contributing to

behavioral changes and functional decline in patients with dementia?

Factors that Affect Function and Behavior in the Cognitively Impaired

Cognitive deficits reduce a person’s ability to deal with:Unmet needs (e.g., physical or psychological)Environmental or social irritantsAcute or chronic illness (medical, psychiatric)Distressing symptoms (e.g., pain, anxiety)Adverse effects of medications

Many of these aggravating factors are modifiable or treatable

Unmet needs that can lead to functional and behavioral changes

Physical needs

— Nutrition, hydration, toileting, exercise, rest

Psychological needs

—Security, autonomy, affection, self-worth

Environmental irritants that can lead to functional and behavioral changes

Physical

— Noise

— Confusing visual stimuli

— Uncomfortable temperature

— Unfamiliar surroundings

Social

— Changes in routines

— Provocative social interactions

Adverse drug effects that can cause functional and behavioral changes

Nuisance symptoms

Anticholinergic effects

Antihistaminic effects

Paradoxical excitation / disinhibition

Intoxication or withdrawal states

Akathisia

Medical conditions and somatic discomfort can alter function and behavior

Somatic discomfort

— Pain

— Constipation

— Urinary urgency

— Shortness of breath

— Dizziness

— Fatigue

Medical condition

— Arthritis

— Dehydration

— Prostatic hypertrophy

— COPD

— Cerebrovascular disease

— CHF

Psychiatric conditions can cause functional and behavioral problems

Depression Delirium Psychosis

— delusions

— hallucinations

Anxiety Sleep disturbance

What do we need to learn as caregivers?

Understand how the cognitively impaired person experiences situations (the environment, social interactions)

Recognize specific factors that cause or contribute to behavioral changes and functional deficits

Once understood, interventions and management strategies become apparent

Person-centered Care: WHAT?

Focus on the elderly person’s experience

— Try to imagine being in their world

— Consider how things look from their perspective

Accept their reality

— Their subjective experience is real to them

— Doesn’t mean you actually adopt their point of view for yourself

Person-centered Care: HOW?

Look for meaning in verbal and non-verbal communication

— Ask, “what do you want? “how can I help?”

— When language comprehension and communication are severely impaired, LOOK AND LISTEN for non-verbal clues to sources of distress or unmet needs

Avoid saying “no”, arguing or disagreeing

Offer to help in ways that reduce distress or meet needs, without compromising safety

QUESTIONS

Signs of IMPAIRMENT IN VARIOUS COGNiTIVE DOMAINS

CLINICAL VIGNETTES
