Management of Increased Behavioral Symptoms in the Elderly
Non-pharmacological interventions must be attempted first as the preferred first-line treatment for all behavioral disturbances in elderly patients, with medications reserved only for severe, persistent symptoms that fail environmental and behavioral approaches or pose significant safety risks. 1, 2, 3
Step 1: Systematic Assessment Using the DICE Approach
Describe the Behavior
- Ask caregivers to describe the behavior "as if in a movie" to capture exact details of what happens, when it occurs, and the surrounding circumstances 1
- Document antecedents, the specific behavior, and consequences using ABC charting over several days to identify environmental triggers 2, 3
- Elicit the patient's perspective when possible to understand what they can describe about the symptoms 1
- Identify what aspect is most distressing to patient and caregiver, and establish their treatment goals 1
Investigate Underlying Causes
Medical causes must be systematically ruled out before attributing behaviors to dementia alone. 2, 3
- Pain (often the primary driver in non-verbal patients) 2, 3
- Infections: urinary tract infections, pneumonia, other systemic infections 2, 3
- Metabolic disturbances: dehydration, constipation, urinary retention 1, 2
- Medication effects: particularly anticholinergic agents that worsen agitation 2, 3
- Sensory impairments: hearing or vision deficits that increase confusion and fear 2
Step 2: Create and Implement Non-Pharmacological Interventions
Environmental Modifications (Most Effective Strategy)
- Remove potential hazards and install safety features like grab bars and handrails 3, 4, 5
- Minimize glare, noise, and household clutter to reduce overstimulation 3, 4
- Eliminate mirrors or reflective surfaces that can trigger hallucinations 3
- Ensure adequate bright light exposure during daytime (2 hours in morning at 3,000-5,000 lux) to regulate circadian rhythms 3
- Reduce nighttime light and noise to create favorable sleep environments 3
Structured Daily Routines
- Establish predictable activities with regular physical exercise, consistent meal times, and fixed bedtimes 3, 4
- Use orientation aids including calendars, clocks, and color-coded labels for navigation 3, 4
- Implement tailored activity-based interventions matched to individual abilities and preferences 3
Communication Strategies
- Use calm tones, simple single-step commands, and gentle touch for reassurance 2, 3, 4
- Apply the "three R's" approach: repeat instructions, reassure the patient, and redirect attention away from anxiety-provoking situations 3, 4
- Allow adequate time for the patient to process information before expecting a response 2
- Avoid harsh tones, complex multi-step commands, open-ended questions, and confrontational approaches 3, 4
Staff and Caregiver Training (Most Effective Strategy)
- Educate caregivers that behaviors are disease symptoms, not intentional actions 3, 5
- Provide training in problem-solving techniques and supported conversation methods 3
- Offer regular support and stage-specific education with anticipatory guidance for disease progression 3
Step 3: Pharmacological Management (Only After Non-Pharmacological Failure)
When to Consider Medications
Medications should only be used in three specific circumstances: 1
- Major depression with or without suicidal ideation
- Psychosis causing harm or with great potential of harm
- Aggression causing risk to self or others
First-Line Pharmacological Options
For Chronic Agitation Without Psychosis
- SSRIs are the preferred first-line pharmacological treatment 2, 3
- Start citalopram 10 mg/day (maximum 40 mg/day) or sertraline 25-50 mg/day (maximum 200 mg/day) 2
- Assess response with quantitative measures after 4 weeks of adequate dosing 2
- Taper and withdraw if no clinically significant response 2
For Severe Agitation With Psychotic Features
- Risperidone: start 0.25 mg at bedtime (maximum 2-3 mg/day in divided doses); risk of extrapyramidal symptoms at 2 mg/day 2
- Olanzapine: start 2.5 mg at bedtime (maximum 10 mg/day); less effective in patients over 75 years 2
- Quetiapine: start 12.5 mg twice daily (maximum 200 mg twice daily); more sedating with risk of orthostasis 2
For Acute Severe Agitation With Imminent Harm
- Haloperidol 0.5-1 mg orally or subcutaneously, maximum 5 mg daily in elderly patients 2
- Use only at the lowest effective dose for the shortest possible duration 2
Critical Safety Considerations
Before initiating antipsychotics, discuss with patient and surrogate decision maker: 2
- Increased mortality risk (particularly in patients over 75 years) 2
- Cardiovascular effects including QT prolongation, dysrhythmias, sudden death, hypotension 2
- Risk of pneumonia, falls, and metabolic effects 2
- Extrapyramidal symptoms, neuroleptic malignant syndrome, and tardive dyskinesia 3
Medications to Avoid
- Typical antipsychotics (haloperidol, fluphenazine, thiothixene) as first-line therapy due to 50% risk of tardive dyskinesia after 2 years of continuous use 2
- Benzodiazepines for routine use due to risk of tolerance, addiction, depression, cognitive impairment, and paradoxical agitation in 10% of elderly patients 2
- Anticholinergic medications that worsen cognitive symptoms 3, 4
Step 4: Evaluate and Monitor
Short-Term Monitoring
- Evaluate response to pharmacological interventions within 30 days 3, 4
- Monitor daily with in-person examination for adverse effects 2
- Consider referral to mental health specialist if minimal or no improvement 4
Long-Term Management
- Review need for continued medication at every visit 2
- Consider tapering or discontinuing medications after 6 months of symptom stabilization 3, 4
- Regularly reassess as neuropsychiatric symptoms fluctuate throughout dementia progression 3, 4
- Avoid inadvertent chronic use: approximately 47% of patients continue receiving antipsychotics after discharge without clear indication 2
Common Pitfalls to Avoid
- Do not use antipsychotics for mild agitation; reserve them for severe symptoms that are dangerous or cause significant distress 2
- Do not rely solely on medications without implementing non-pharmacological strategies first 3, 4
- Do not underestimate pain and discomfort as causes of behavioral disturbances, especially in non-verbal patients 2, 3
- Do not continue antipsychotics indefinitely; review need at every visit and taper if no longer indicated 2
- Do not use benzodiazepines as first-line for agitated delirium as they can increase delirium incidence and duration 2
