What is the appropriate management for a patient, particularly geriatric or those with a history of dementia, presenting with altered psychomotor activity, such as agitation, restlessness, or slowed movements?

Management of Altered Psychomotor Activity in Geriatric Patients with Dementia

For geriatric patients with dementia presenting with altered psychomotor activity, immediately investigate and treat reversible medical causes (pain, infections, metabolic disturbances) while implementing non-pharmacological interventions first; reserve pharmacological treatment—starting with SSRIs for chronic agitation or low-dose haloperidol (0.5-1 mg) for severe acute agitation—only when symptoms are dangerous, cause significant distress, and behavioral approaches have failed. 1, 2

Immediate Assessment Priorities

Identify Reversible Medical Triggers

Before any pharmacological intervention, systematically investigate underlying causes that commonly drive behavioral disturbances in patients who cannot verbally communicate discomfort:

• Pain assessment and management is the single most important contributor to behavioral disturbances and must be addressed first 2
• Infections: Check for urinary tract infections and pneumonia, which are disproportionately common triggers of agitation 2
• Metabolic disturbances: Evaluate for hypoxia, dehydration, electrolyte abnormalities, hypoglycemia, and constipation/urinary retention 2, 3
• Medication review: Identify and discontinue anticholinergic agents (diphenhydramine, oxybutynin, cyclobenzaprine) that worsen confusion and agitation 2

Characterize the Agitation Pattern

• Document the type, frequency, severity, pattern, and timing of symptoms using the "DESCRIBE" approach 2
• Use ABC (antecedent-behavior-consequence) charting to identify specific environmental triggers 2
• Clarify what "agitation" means—anxiety, repetitive questions, aggression, wandering, or verbal outbursts each require different management 2
• Establish baseline severity using quantitative measures (Cohen-Mansfield Agitation Inventory or NPI-Q) 2, 4

Non-Pharmacological Interventions (First-Line)

These must be attempted and documented as failed before considering medications, except in emergency situations with imminent risk of harm. 1, 2

Environmental Modifications

• Ensure adequate lighting, particularly during late afternoon for sundowning agitation 2
• Reduce excessive noise and provide quiet spaces 2
• Install safety equipment (grab bars, bath mats) and simplify the environment with clear labels 2
• Provide 2 hours of morning bright light exposure (3,000-5,000 lux) to consolidate sleep-wake cycles 2
• Increase supervised mobility with at least 30 minutes of daily sunlight exposure 2

Communication and Behavioral Strategies

• Use calm tones, simple one-step commands, and gentle touch for reassurance rather than complex multi-step instructions 2
• Allow adequate time for the patient to process information before expecting a response 2
• Establish predictable daily routines and structured activities tailored to individual abilities 2
• Maintain consistency of caregivers and minimize relocations 2
• Encourage family presence and bring familiar objects from home 2

Pharmacological Management Algorithm

When to Consider Medications

Medications should ONLY be used when: 1, 2

• Symptoms are severe, dangerous, or cause significant distress to the patient
• The patient is threatening substantial harm to self or others
• Behavioral interventions have been thoroughly attempted and documented as insufficient
• Emergency situations with imminent risk of harm

Critical Safety Discussion Required

Before initiating any antipsychotic, discuss with the patient (if feasible) and surrogate decision maker: 1, 2

• Increased mortality risk (1.6-1.7 times higher than placebo)
• Cardiovascular effects including QT prolongation, sudden death, stroke risk
• Falls, hypotension, pneumonia, and metabolic effects
• Expected benefits and treatment goals
• Plans for ongoing monitoring and reassessment

Medication Selection by Clinical Scenario

For Chronic Agitation WITHOUT Psychotic Features (First-Line: SSRIs)

SSRIs are the preferred pharmacological option for chronic agitation, particularly in vascular dementia: 2

• Citalopram: Start 10 mg/day, maximum 40 mg/day 2, 4

  • Well-tolerated, though some patients experience nausea and sleep disturbances 2
  • Requires 4-8 weeks for full therapeutic effect 2

• Sertraline: Start 25-50 mg/day, maximum 200 mg/day 2, 4

  • Minimal drug interactions and excellent tolerability 2
  • Significantly reduces overall neuropsychiatric symptoms, agitation, and depression in vascular cognitive impairment 2

Monitoring: Assess response within 4 weeks using quantitative measures; if no clinically significant response after 4 weeks at adequate dose, taper and withdraw 1, 2

For Severe Acute Agitation WITH Imminent Risk of Harm (Antipsychotics)

Low-dose haloperidol is the first-line medication for acute agitation when non-pharmacological interventions have failed: 2

• Haloperidol: 0.5-1 mg orally or subcutaneously, maximum 5 mg daily in elderly patients 2
  • In frail elderly, start with 0.25-0.5 mg and titrate gradually 2
  • Provides targeted treatment with lower risk of respiratory depression compared to benzodiazepines 2
  • Requires ECG monitoring for QTc prolongation 2
  • Monitor for extrapyramidal symptoms (tremor, rigidity, bradykinesia) 2

Alternative for severe agitation with psychotic features:

• Risperidone: Start 0.25 mg at bedtime, target 0.5-1.25 mg daily, maximum 2-3 mg/day 2

  • Risk of extrapyramidal symptoms at doses >2 mg/day 2
  • Three-fold increase in stroke risk in elderly dementia patients with vascular disease 2

• Quetiapine: Start 12.5 mg twice daily, maximum 200 mg twice daily 2

  • More sedating with risk of orthostatic hypotension 2
  • Second-line option due to sedation profile 2

• Olanzapine: Start 2.5 mg at bedtime, maximum 10 mg/day 2

  • Less effective in patients over 75 years 2
  • Risk of oversedation and metabolic effects 2

Alternative Options for Chronic Agitation (If SSRIs Fail)

• Trazodone: Start 25 mg/day, maximum 200-400 mg/day in divided doses 2, 4

  • Use caution in patients with premature ventricular contractions due to orthostatic hypotension risk 2
  • Safer alternative to antipsychotics with better tolerability profile 2

• Divalproex sodium: Start 125 mg twice daily, titrate to therapeutic blood level 2

  • For severe agitation without psychotic features 2
  • Requires monitoring of liver enzymes and coagulation parameters 2

What NOT to Use

Benzodiazepines should be AVOIDED as first-line treatment except for alcohol/benzodiazepine withdrawal: 2, 4

• Increase delirium incidence and duration 2
• Cause paradoxical agitation in approximately 10% of elderly patients 2, 4
• Risk of tolerance, addiction, cognitive impairment, respiratory depression, and falls 2
• Lorazepam 0.25-0.5 mg may be considered ONLY for breakthrough agitation while optimizing other treatments 4

Typical antipsychotics (other than haloperidol for acute situations) should be avoided: 2

• 50% risk of tardive dyskinesia after 2 years of continuous use in elderly patients 2

Anticholinergic medications worsen agitation and should be discontinued: 2

• Diphenhydramine, hydroxyzine, oxybutynin, cyclobenzaprine all worsen confusion and agitation 2

Dosing Principles and Duration

• Start low: Begin with 50% of adult starting dose 2
• Go slow: Titrate to minimum effective dose as tolerated 1, 2
• Use shortest duration: Evaluate daily with in-person examination 2
• Attempt taper: Within 3-6 months to determine if still needed 2
• Avoid indefinite use: Approximately 47% of patients continue antipsychotics after discharge without clear indication 2

Monitoring and Reassessment

For Antipsychotics

• Daily in-person examination to assess ongoing need 2
• ECG monitoring for QTc prolongation 2
• Monitor for extrapyramidal symptoms, falls, sedation, metabolic changes 1, 2
• Assess for cognitive worsening 2
• Review need at every visit 2

For SSRIs

• Assess response within 4 weeks using the same quantitative measure used at baseline 1, 2
• Monitor for gastrointestinal disturbances and sleep changes 4
• If positive response, periodically reassess need for continued medication 1
• After 9 months of treatment for first episode, reassess necessity 2

Special Considerations

Patients Over 75 Years

• Respond less well to antipsychotics, particularly olanzapine 2
• Require even lower starting doses and more gradual titration 2

Vascular Dementia

• SSRIs are explicitly designated as first-line pharmacological treatment 2
• Antipsychotics carry three-fold increased stroke risk 2
• Reserve antipsychotics only for severe, dangerous agitation when SSRIs and behavioral approaches have failed 2

Sundowning Agitation

• Increase daytime bright light exposure (2 hours of morning bright light at 3,000-5,000 lux) 2
• Avoid bright light in evening 2
• Increase supervision and structured activities during late afternoon 2
• Consider timing medication doses to provide coverage during peak agitation hours 2

Common Pitfalls to Avoid

• Never add multiple psychotropics simultaneously without first treating reversible medical causes 2
• Never use antipsychotics for mild agitation or behaviors like unfriendliness, poor self-care, repetitive questioning, or wandering—these are unlikely to respond 2
• Never continue antipsychotics indefinitely without regular reassessment and taper attempts 1, 2
• Never skip non-pharmacological interventions unless in an emergency situation 1, 2
• Never use benzodiazepines routinely for agitation management in dementia 2, 4
• Never ignore polypharmacy—systematically review and deprescribe before adding new medications 2
