Dementia-Related Agitation: A Comprehensive Guide for Nurses

Dementia-related agitation is a common and challenging symptom in individuals with dementia, characterized by restlessness, emotional distress, and disruptive behaviors. Effective management requires a compassionate, patient-centered approach that addresses both the underlying causes and the immediate symptoms. Nurses play a pivotal role in assessing, managing, and supporting patients with agitation, as well as educating and involving family members in care strategies.

Understanding Dementia-Related Agitation

Definition

Agitation in dementia refers to a range of behavioral and psychological symptoms, including:

• Restlessness or pacing
• Verbal aggression (yelling, screaming)
• Physical aggression (hitting, pushing)
• Wandering
• Resistance to care

These behaviors often result from unmet needs, environmental factors, or progression of the disease affecting the brain's ability to process information and regulate emotions.

Causes and Risk Factors

1. Biological Factors
   • Disease Progression: Advancing dementia affects brain regions responsible for behavior and emotional control.
   • Pain or Discomfort: Unidentified pain (e.g., from arthritis, infections) can cause agitation.
   • Medical Conditions: Infections, dehydration, or constipation may contribute.
   • Medication Side Effects: Polypharmacy or certain drugs (e.g., anticholinergics) can exacerbate symptoms.
   • Sensory Impairments: Hearing or vision loss leads to misinterpretation of the environment.
2. Psychological Factors
   • Anxiety and Depression: Common in dementia and may manifest as agitation.
   • Delusions or Hallucinations: Misperceptions can cause fear and aggressive behaviors.
   • Frustration: Difficulty communicating needs or performing tasks.
3. Environmental Factors
   • Overstimulation: Loud noises, crowded spaces.
   • Understimulation: Boredom due to lack of engaging activities.
   • Changes in Routine: Alterations in daily schedules or caregivers.
   • Unfamiliar Surroundings: Hospitalizations or new living environments.

Clinical Presentation

Symptoms

• Physical Behaviors: Pacing, restlessness, wandering, repetitive movements.
• Verbal Behaviors: Shouting, cursing, moaning, repetition of words or phrases.
• Aggressive Behaviors: Hitting, biting, kicking, pushing.
• Emotional Symptoms: Irritability, anxiety, fearfulness, anger.

Timing and Triggers

• Sundowning: Increased agitation in the late afternoon or evening.
• Specific Activities: Resistance during bathing, dressing, or toileting.
• Environmental Changes: Shift changes, new caregivers, relocation.

Assessment

1. Comprehensive Evaluation

• Medical History: Review of current and past medical conditions.
• Medication Review: Identify drugs that may contribute to agitation.
• Pain Assessment: Use appropriate scales (e.g., Pain Assessment in Advanced Dementia [PAINAD] scale).
• Cognitive Assessment: Determine the stage of dementia.
• Functional Assessment: Evaluate the ability to perform activities of daily living (ADLs).
• Behavioral Assessment: Document frequency, duration, and triggers of agitation.

2. Assessment Tools

• Neuropsychiatric Inventory (NPI): Measures behavioral disturbances in dementia.
• Cohen-Mansfield Agitation Inventory (CMAI): Assesses agitation frequency and types.
• Cornell Scale for Depression in Dementia: Screens for depression contributing to agitation.

Management Strategies

Goals of Care

• Ensure Safety: Protect the patient and others from harm.
• Identify and Address Underlying Causes: Medical, psychological, or environmental factors.
• Improve Quality of Life: Enhance comfort and well-being.
• Minimize Use of Restraints and Psychotropic Medications: Prioritize non-pharmacological interventions.

1. Non-Pharmacological Interventions

a. Person-Centered Care

• Individualized Approach: Tailor care to the person's history, preferences, and abilities.
• Effective Communication:
  • Use simple, clear language.
  • Maintain eye contact and a calm tone.
  • Allow time for responses.

b. Environmental Modifications

• Reduce Overstimulation: Limit noise, crowds, and unnecessary activities.
• Enhance Safety: Remove hazards, ensure adequate lighting.
• Establish Routine: Maintain consistent schedules for meals, activities, and sleep.
• Familiar Items: Incorporate personal belongings to provide comfort.

c. Behavioral Strategies

• Distraction and Redirection: Engage the patient in a preferred activity when agitation arises.
• Validation Therapy: Acknowledge feelings without challenging misconceptions.
• Reminiscence Therapy: Discuss past experiences to evoke positive emotions.
• Music and Art Therapy: Utilize creative outlets to reduce anxiety.

d. Address Physical Needs

• Pain Management: Administer analgesics as prescribed.
• Hunger and Thirst: Offer snacks and fluids regularly.
• Toileting Needs: Provide scheduled bathroom visits to prevent discomfort.

2. Pharmacological Interventions

a. Antipsychotic Medications

• Indications: Severe agitation or psychosis causing significant distress or danger.
• Common Medications:
  • Risperidone
  • Olanzapine
  • Quetiapine
• Considerations:
  • Use the lowest effective dose.
  • Monitor for side effects (e.g., extrapyramidal symptoms, sedation).
  • Black box warning for increased mortality in elderly patients with dementia.

b. Antidepressants

• Selective Serotonin Reuptake Inhibitors (SSRIs): May help with agitation linked to depression or anxiety.
• Examples:
  • Citalopram
  • Sertraline

c. Other Medications

• Mood Stabilizers: Limited evidence; used cautiously.
• Cholinesterase Inhibitors and Memantine: May have modest benefits on behavior.

d. Medication Review

• Deprescribing: Discontinue non-essential medications that may contribute to agitation.
• Regular Monitoring: Assess effectiveness and side effects frequently.

Nursing Interventions

1. Assessment and Monitoring

• Behavioral Logs: Document episodes of agitation, triggers, and effective interventions.
• Vital Signs: Monitor for signs of pain, infection, or other medical issues.
• Medication Effects: Observe for therapeutic benefits and adverse reactions.

2. Communication Techniques

• Calm Approach: Remain patient and avoid showing frustration.
• Positive Reinforcement: Praise cooperative behavior.
• Non-Verbal Cues: Use gentle touch and reassuring gestures when appropriate.

3. Environmental Management

• Safe Environment: Remove dangerous objects, secure exits if wandering is a risk.
• Comfort Measures: Adjust room temperature, provide comfortable seating.

4. Behavioral Strategies

• Activity Planning: Schedule engaging activities during times agitation is likely.
• Rest Periods: Allow for quiet time to prevent fatigue-related agitation.

5. Collaboration

• Interdisciplinary Team: Work with physicians, occupational therapists, social workers.
• Family Involvement: Engage family members in care planning and implementation.

Family Education and Support

1. Understanding Dementia and Agitation

• Disease Education: Explain how dementia affects behavior.
• Setting Realistic Expectations: Prepare families for potential challenges.
