Treatment of Agitation in Dementia
Non-pharmacological interventions should be the first-line treatment for agitation in dementia, with structured activities, environmental modifications, and sensory interventions showing the strongest evidence for reducing agitation. 1, 2, 3
Initial Assessment and Evaluation
Before implementing any treatment, screen for underlying reversible causes of agitation through systematic evaluation 1, 2, 3:
- Investigate and treat pain, which is frequently undertreated and commonly manifests as agitation in dementia patients 2, 3
- Rule out urinary tract infections as a potential trigger 1, 2
- Assess for other medical causes including constipation, medication side effects, or environmental stressors 1
- Use quantitative measures to document the type, frequency, severity, and timing of agitation symptoms 3
Non-Pharmacological Interventions (First-Line Treatment)
Structured Activities and Environmental Modifications
Implement individualized, structured activities tailored to the person's current capabilities and previous interests 1, 2:
- Activity-based interventions (such as Montessori activities) increase positive affect and reduce agitation in severe dementia 1
- Establish predictable daily routines for exercise, meals, and bedtime 2
- Reduce environmental triggers by minimizing noise and optimizing lighting 2, 3
Sensory Interventions (Strongest Evidence)
Sensory interventions demonstrate the most robust evidence for reducing agitation (SMD -1.07; 95% CI -1.76 to -0.38) 4:
- Massage and touch therapy show clinical efficacy (SMD -0.75) 5
- Music combined with massage therapy demonstrates even greater benefit (SMD -0.91) 5
- Simulated presence therapy using family-prepared audio/video recordings can be effective 2
Additional Non-Pharmacological Approaches
- Animal-assisted interventions may reduce agitation 2
- The "three R's" approach: repeat instructions, reassure the patient, and redirect attention away from problematic situations 2
- Multidisciplinary care coordination shows clinical benefit (SMD -0.5) 5
Pharmacological Management (Second-Line)
Only consider medications when symptoms are severe, dangerous, or causing significant distress, and after non-pharmacological interventions have been exhausted 2, 3, 6.
SSRIs (First-Line Pharmacological Option)
SSRIs are the preferred first-line pharmacological treatment for agitation in dementia 2:
- Citalopram or sertraline significantly reduce overall neuropsychiatric symptoms and agitation 2
- Start at low doses and titrate slowly 2
- Monitor for side effects including sweating, tremors, nervousness, insomnia/somnolence, dizziness, and gastrointestinal disturbances 2
- Consider use in conjunction with cholinesterase inhibitors for enhanced benefit 7, 8
Atypical Antipsychotics (Use with Extreme Caution)
Atypical antipsychotics should only be used for severe, dangerous agitation when other interventions have failed, recognizing their modest benefits (SMD -0.21) and significant risks 3, 6:
- Risperidone 0.5-2.0 mg/day may be considered for severe agitation with careful risk assessment 3, 6
- Quetiapine starting at 12.5 mg twice daily (maximum 200 mg twice daily) can be used, but monitor closely for sedation and orthostatic hypotension 6
- Avoid typical antipsychotics (haloperidol) due to severe sensitivity reactions and high risk of extrapyramidal symptoms 6
- Discuss risks including increased mortality and serious adverse events with patients and surrogate decision-makers before initiating 3, 6
Medication Initiation and Monitoring Protocol
When pharmacological treatment is necessary 2, 3:
- Start at the lowest possible dose and titrate slowly to minimum effective dose 3, 6
- Use quantitative measures to assess treatment response 2, 3
- If no clinically significant response after 4 weeks of adequate dosing, taper and withdraw the medication 2, 3
- Periodically reassess the need for continued medication even with positive response 2, 3
- If significant side effects develop, review risk/benefit balance and consider tapering or discontinuing 2, 3, 6
Critical Pitfalls to Avoid
- Never use antipsychotics as first-line treatment—the benefits are modest at best while risks are substantial 3, 5
- Do not overlook pain as a reversible cause of agitation, as it frequently presents as behavioral disturbance 2, 3
- Avoid continuing medications indefinitely without reassessment—regularly evaluate ongoing need 2, 3
- Do not use typical antipsychotics due to unacceptable side effect profiles 6
