Delirium and Dementia Flashcards
Three DS of cognitive impairment in Older adults
- Delirium
- Dementia
- Depression
What is Delirium
is Acute confusion characterized by sudden and temporary changes in cognition, attention, memory and perception
- Cause: unknown, thought to be disturbances in the
Neurotransmitters with multifactorial causes. - Predisposing and precipitating risk factors: Ex. advanced age, depression, polypharmacy, chronic medical condition, alcoholism
Delirium Prevalence
- 22% IN COMMUNITY-LIVING PEOPLE
- 15% TO 70% IN LONG-TERM CARE RESIDENTS
- 11% TO 33% UPON ADMISSION TO HOSPITAL
* + 5% TO 35% DELIRIUM DEVELOPING AFTER ADMISSION - 80% OR MORE IN INTENSIVE CARE SETTINGS
Types of Delirium
- Hyperactive
- Hypoactive
- Mixed
Hyperactive delirium
Agitation, hallucinations, restlessness, and hyperactivity
Hypoactive delirium
lethargy, decreased motor activity
Mixed delirium
Fluctuation between hyperactive and hypoactive
Functional Consequences of Delirium
- Delirium is a medical emergency
- Longer hospital stays
- Higher rate of LTC residency
- Short and long-term functional impairment
- Development of or worsening of Dementia
Why is delirium unrecognized in LTC?
Delirium is often unrecognized in long-term care (LTC) because its symptoms, such as confusion, agitation, or lethargy, can be mistaken for normal aging, dementia, or other chronic conditions.
Nursing assessment for Delirium
- Assess and treat predisposing factors (pre-existing factors)
- Keep individual safe until delirium is resolved
Most Common Nursing assessment for Delirium
CAM (The Confusion assessment method): The diagnosis of delirium by CAM requires the presence of feature 1 and 2 and either 3 or 4
- FEATURE 1: ACUTE ONSET OR FLUCTUATING COURSE
- FEATURE 2: INATTENTION
- FEATURE 3: DISORGANIZED THINKING
- FEATURE 4: ALTERED LEVEL OF CONSCIOUSNESS
Delirium Intervention
- Pharmacological intervention
- Non-pharmacological intervention
Pharmacological Intervention for Delirium
- Pharmacological treatment of delirium is not recommended
- Review Patient medication
- Limit use of psychoactive medication to specific symptoms
- Discontinue nonessential medications
& BENZODIAZEPINES/PSYCHOTROPIC MEDICATIONS ARE USED FOR
DELIRIUM ASSOCIATED WITH ALCOHOL WITHDRAWAL
Non-pharmacological intervention for Delirium
- Physiological stability/reversable cause
- Environmental
- Education
- Communication
Treatment of Delirium is focused on
- Possible contributing factors
- Safety to address function and behavioral changes
- Managing aggravating factors that might worsen the Delirium
What is Dementia
Is an Irreversible loss of cognitive functioning
- Key features: Aphasia (difficulty speaking), apraxia (unable to perform tasks or movements when asked), Agnosia (neurological disorder on recognition), Disturbances in executive functioning (unable to think or plan)
Cause: Damage to or loss of nerve cells and their connections in the brain
Risk Factors: Mis-management of diabetes, depression,
Types of Dementia
- Alzheimer (Most dementia is Alzheimer’s, genetic components)
- Vascular (diseased blood vessels, dying blood vessels in the brain,
leads to brain death,) (Hypertension, Stroke, Cardiovascular
disease cause Vascular dementia) - Lewy body (presence of abnormal proteins)
- Frontotemporal (frontal and temporal lobes damaged/lost)
Dementia Prevalence
- CHALLENGING TO DETERMINE
* DEMENTIA IS A GROUP OF DISEASES, EACH WITH DIFFERENT
MANIFESTATIONS AND COMBINATIONS OF SYMPTOMS
* SPECIFIC DEMENTIAS MAY NOT BE IDENTIFIED UNTIL AFTER
DEATH - ALZHEIMER’S DISEASE ACCOUNTS FOR 60% TO 80% OF DEMENTIA
- VASCULAR DEMENTIA 11% TO 18% (22% - 34% WITH AD)
- LEWY BODY AND PARKINSON DISEASE 15% - 20%
Functional Consequences of Dementia
- FUNCTIONAL CONSEQUENCES VARY AMONG
INDIVIDUALS - LOSS OF PERSONHOOD AND SELF-WORTH
- FEEL ISOLATED AND DEPRESSED
- MAY BE DIFFICULT TO RECOGNIZE AND/OR
ACKNOWLEDGE
Nursing assessment of Dementia
- INITIAL & ONGOING ASSESSMENT
* MMSE (Mini-mental state examination)
* BEHAVIOUR AND PSYCHOLOGICAL SYMPTOMS OF
DEMENTIA (BPSD) - NURSING DIAGNOSIS TO INDIVIDUALIZE INTERVENTIONS
Dementia Intervention
Pharmacological intervention
Non-pharmacological intervention
Pharmacological Intervention for Dementia
- MOST MEDICATIONS FOR DEMENTIA ARE TO STABILIZE
DISEASE ETIOLOGY AND PROGRESSION, AND MANAGE
SYMPTOMS - ALZHEIMER’S DISEASE DOES HAVE SPECIFIC MEDICATIONS
- UNDERLYING CARDIAC FACTORS FOR VASCULAR DEMENTIA
CAN BE TREATED - ADVERSE EFFECTS ARE COMPLEX TO RESOLVE
Non-pharmacological interventions for Dementia
- EDUCATION
- ENVIRONMENTAL MODIFICATION
- COMMUNICATION SKILLS
- ALTERNATIVE THERAPIES FOR DEMENTIA
The Nursing Process for those with Dementia
- ASSESSMENT
* FACTORS AFFECTING QUALITY OF LIFE - PLANNING
* FOR QUALITY OF LIFE AND FUNCTION - DIAGNOSIS
* FUNCTION, COGNITION, BEHAVIORAL,
CAREGIVER - INTERVENTIONS
* INTERPROFESSIONAL (P. 269 THERAPIES) - EVALUATION
* QUALITY OF LIFE
