What is delirium?

It is an organic mental disorder characterized by a cluster of cognitive impairments with an acute onset and identification of a specific precipitating stressor

2

What are the characteristics of delirium?

  1. A disturbance in attention and awareness
  2. Develops over a short period of time and tends to fluctuate in severity during the course of a day
  3. An additional disturbance in cognition (memory deficit, disorientation, language, visuospatial ability, perception)
  4. Disturbances in 1 and 3 are not better explained by another neurocognitive disorder
  5. Direct result of:
    • Medical condition
    • Substance intoxication or withdrawal
    • Exposure to a toxin
    • Multiple etiologies

3

What classifies someone as having substance intoxication delirium?

When symptoms in Criteria A and C predominate in the clinical picture and when they are sufficiently severe to warrant clinical attention

4

Describe the realtionship between age and gender and delirium?

  • Risk is greater for women
  • Most prevalent in children and those over 60 years of age
  • Children may be more prone than adults
    • Medication
    • Febrile response
    • Anxiety

5

What is the prognosis for a patient with delirum?

  • Medical emergency!!!
  • Reversible if diagnosed and treated early
  • May remit spontaneously
  • May progress to dementia and other chronic problems
  • With treatment- 1 to several weeks
  • 10% of clients progress to coma and death

6

What would you use to assess a patient for possible delirium?

  • Mental status exam
  • Mini-mental status exam
  • Assess memory, thought processes, attention, and concentration
  • Involve family members and significant others as historians
  • Behavioral rating scales
  • Assessment of medication combinations

7

What are some nursing interventions for delirum?

  • Individualized, based on cause 
  • Prioritize patient safety
  • Use alternatives to physical restraints , use least restrictive methods first!!
  • Reality based treatment --> music, flowers to smell,
  • Avoid escalating anxiety --> reduce noise, coordinate the lighiting,
  • Pharmacological interventions
    • benzodiazepines  (would wnat to use adavan & serax because of short halflife)
    • anxiolytic (BuSpar)
    • antipsychotics
    • dexmedetomidine
  • Delirium assessment
  • Pain management
  • Early mobilization
  • Elimination of unnecessary medication
  • Interdisciplinary team management

8

What are some outcomes for patients with delirium?

  • No injuries
  • Return to baseline functioning
  • Ability to communicate thoughts and feelings
  • Ability to understand others

9

What is the criteria to be diagnosed with major neurocognitive disorder?

  • Evidence of significant cognitive decline from a previous level of performance in one or more cognitive domains:
    • Attention
    • Executive function
    • Learning
    • Memory
    • Language
    • Perceptual-motor
  • The cognitive deficits:
    • Interfere with independence in everyday activities
    • Do not occur exclusively in the context of a delirium
    • Are not better explained by another mental disorder

10

What is the critqeria to be diagnosed with mild NCD?

  • Evidence of modest cognitive decline from a previous level of performance in one or more cognitive domains:
    • Attention
    • Executive function
    • Learning
    • Memory
    • Language
    • Perceptual-motor
  • The cognitive deficits:
    • Do not interfere with independence in everyday activities
    • Do not occur exclusively in the context of a delirium
    • Are not better explained by another mental disorder

11

What are the characteristics of major or mild NCC due to Alzheimer's?

14

How can alzheimer's be diagnosed?

15

What are some biological theories for the cause of Alheimer's?

  • rivastigmine (Exelon)
Antipsychotic therapy
  • haloperidol (Haldol)
  • risperidone (Risperdal)
Benzodiazepines
Hypnotics
Antidepressants

20

How are patients with Major or Mild Vascular NCD diagnosed?  Describe the pathophysiology

  • Small emboli or strokes
  • Computed tomography (CT) and magnetic resonance imaging (MRI)
  • Multiple lesions of the cerebral cortex and the sub-cortical structures of the brain
  • EEG may reveal focal lesions
  • Diagnosis based on:
    • history of CAD
    • reported episodic decline in function
    • physical examination of neurological abnormalities

21

What is the prognosis for patients with mild or major vascular NCD?

  • May be preventable
  • Aggressive treatment may reduce incidence and severity
  • Early indicators/Risk factors
    • Risk for CAD
    • Declining scores on mental status exams

22

What are some nursing interventions for dementia (neurocognitive declines)?

  • Medication management
    • Nootropics  - “smart drugs”
  • Family support and education
  • Manage therapeutic environment
  • Physical assessment
  • Monitoring and maintenance
    • vital signs
    • fluid and nutritional intake

Chronic Confusion

  • Provide other information about support systems in community
  • Refer family members for a physical examination
  • Provide health promotion education
  • Teach stress management skills
  • Teach about medications
  • Explain patient may use confabulation in social situations and give rationale
  • Inform family that client responds better to reminiscences about the past rather than to “here and now.”
