Why it matters

25% of patients visiting a health service have at least one mental, neurological or behavioural disorder

Cognitive problems more common amongst older persons

Older persons a significant proportion of hospital patients

> 65 ~ 13% population > 65 ~ 39% hospital patients> 65 ~ 48% hospital bed days

Why it matters

Cognition

cognōscere “to know”

the process of knowing

thinking, thoughts

capacity to understand / interpret information

Cognition

processing of information

memory + thoughts

store, retrieve and manipulate information

disruption to this process = cognitive disorder

Disorders of Cognition Sx

impaired awareness

reasoning

memory

judgment

perception

disorientation (time +/or place +/or person)

Dementia

“a progressive illness that involves cognitive and non-cognitive abnormalities and disorders of

behaviour; presents as a gradual failure of brain function. It is not a normal part of life or aging.”

Elder, Evans & Nizette (2013) pp 525

Dementia

aka Neurocognitive Disorders due to…

Alzheimer’s Disease

Vascular Disease

Lewy Bodies

Prion Disease

HIV Infection

Delirium“go off the furrow”

"off the track“

not a disease: a syndrome

a medical emergency: associated with increased morbidity and mortality rates

up to 56% of older people in hospitalInouye S, 1994. ‘The dilemma of delirium: clinical and research controversies regarding diagnosis and evaluation of

delirium hospitalized elderly medical patients’ American Journal of Medicine 97(3):278–88.

Some Causes of Delirium

Hyperthyroidism Hypothyroidism HypercalcaemiaHyponatraemia

Urinary Tract InfectionPneumonia

Septicaemia Stroke

Subarachnoid Haemorrhage Unmanaged Pain (esp. old age)

Head Trauma Fractures (esp. Hip & Rib)

Hypoglycaemia

Vitamin B12 DeficiencyFolate Deficiency

Sedatives Antihistamines

Alcohol Benzodiazepines

OpiatesAnticholinergics

Urinary RetentionConstipation

Faecal ImpactionSevere Diarrhoea

Changes In Environment

Diagnosis

Under-diagnosis common: up to 50%

Contributing factors:Hypoactive deliriumOld ageMisdiagnosed as depression or dementia

Important because:Worse prognosisPrevents detection and management of other sxIncreases family’s distress

Communication between staff

Fluctuating nature may lead to tension between different staff groups:

Emphasise fluctuation as core symptom

Use of validated scales

Differences in pharmacological approachesTreat early but at low dose

Communication with the Family

Valuable source of baseline data

“Patrick seems to be having difficulty concentrating at times. How was he before he

came into hospital?”

Gagnon et al (2002):60% of 124 caregivers hadn’t realised possibility of delirium

All care-givers expressed distress

Compare & ContrastDementia Delirium

Onset Insidious Acute

Duration Months/years Hours/days/ ??weeks

Course Stable & progressive (unless vascular dementia – usually stepwise)

Fluctuates – worse at nightLucid periods

Orientation May be normal – usually impaired for time and place

Fluctuates, but will always be impaired in some aspect: Time, Place, Person?

Memory Impaired recent & sometimes remote memory

Recent impaired

Compare & ContrastDementia Delirium

Thoughts Slowed Reduced interests Perserverant Delusions are common

Often paranoid & grandiose ? bizarre ideas & topics ? paranoid

Perception ? normal Visual & auditory hallucinations common Delusions are common

Emotions Shallow, apathetic, labile, ? irritable, careless

Irritable Aggressive Fearful

Sleep Often disturbed. Nocturnal wandering common. Nocturnal confusion.

Nocturnal confusion and/or “sundowning” common.

Other considerations?

Brief screening tool not diagnostic tool

More sensitive to frontal lobe impairment

The Confusion Assessment Method (CAM) Diagnostic Algorithm

1: Acute Onset & Fluctuating Course2: Inattention

3: Disorganised Thinking4: Altered Level of Consciousness

features 1 & 2 and either 3 or 4 = diagnosis of delirium

Environmental Strategies

Lighting appropriate to time of day Low Stimulus Environment Clock & calendar that clients can see Encourage family to visit/stay Bring in client’s personal and familiar objects Avoid room changes

Clinical Practice Strategies [1]

Interpreter for culturally & linguistically diverse (CALD) patients/clients

Indigenous Liaison Officer Eating & Drinking Hearing Aids? Glasses? Bowels – avoid constipation Mobilisation

Clinical Practice Strategies [2]

Encourage independence in basic ADLs Medication review Promote sufficient sleep at night Manage discomfort or pain Provide orienting information Minimise use of indwelling catheters Avoid use of physical restraints Avoid polypharmacy/psychoactive drugs

After Delirium Resolves

Many patients remember being deliriousSymptoms resolve, but the feelings remain

Not always discussed:Fear of being thought mad

Health professionals may assume no recall
