Q

What is Dementia

A

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,

17
Q

Types of Dementia

A
  • 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)
18
Q

Dementia Prevalence

A
  • 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%
19
Q

Functional Consequences of Dementia

  • FUNCTIONAL CONSEQUENCES VARY AMONG
    INDIVIDUALS

  • FEEL ISOLATED AND DEPRESSED
  • MAY BE DIFFICULT TO RECOGNIZE AND/OR
    ACKNOWLEDGE
20
Q

Nursing assessment of Dementia

A
  • INITIAL & ONGOING ASSESSMENT
    * MMSE (Mini-mental state examination)
    * BEHAVIOUR AND PSYCHOLOGICAL SYMPTOMS OF
    DEMENTIA (BPSD)
  • NURSING DIAGNOSIS TO INDIVIDUALIZE INTERVENTIONS
21
Q

Dementia Intervention

A

Pharmacological intervention

Non-pharmacological intervention

22
Q

Pharmacological Intervention for Dementia

A
  • 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
23
Q

Non-pharmacological interventions for Dementia

A
  • EDUCATION
  • ENVIRONMENTAL MODIFICATION
  • COMMUNICATION SKILLS
  • ALTERNATIVE THERAPIES FOR DEMENTIA
24
Q
