Management of Anxiety in Dementia

Non-Pharmacological Interventions

The American College of Cardiology is not applicable here, however, person-centered non-pharmacological interventions should always be implemented before considering medication for patients with dementia and anxiety 1
Assess for potentially modifiable contributors to anxiety and agitation, particularly pain, which is often undertreated and can manifest as agitation in dementia patients 1
Develop individualized care plans addressing environmental factors, sensory needs, and personal preferences 1
Implement environmental modifications such as reducing noise and providing appropriate lighting 1
Establish structured daily routines and meaningful activities tailored to the person's interests and abilities 1

Medications should only be used when symptoms are severe, dangerous, or causing significant distress, as recommended by the American Academy of Family Physicians 1, 2
Only consider pharmacological interventions after non-pharmacological approaches have failed 1
Quetiapine: Start at very low doses (12.5mg twice daily) and titrate slowly while monitoring for adverse effects, with a maximum dose of 200mg twice daily, as suggested by the American Family Physician 2
Risperidone: Consider at 0.5-2.0mg/day for agitated dementia with delusions, according to the American Family Physician 3, 1

Avoid typical antipsychotics (haloperidol, etc.) due to severe sensitivity reactions and high risk of extrapyramidal symptoms, as warned by the American Family Physician 2
Start at the lowest possible dose and titrate slowly to the minimum effective dose, as recommended by the American Academy of Family Physicians 1, 2
Discuss potential risks and benefits with the patient (if feasible) and surrogate decision-makers before starting any medication, as advised by the American Family Physician 1, 2
The benefits of antipsychotic medications in dementia are modest at best (SMD -0.21, 95% CI -0.30 to -0.12) 1
Monitor closely for adverse effects, particularly sedation and orthostatic hypotension with quetiapine, as cautioned by the American Family Physician 2

Use quantitative measures to assess response to treatment, as recommended by the American Academy of Family Physicians 1
Regularly reassess the need for continued medication, as advised by the American Family Physician 1, 2
If significant side effects develop, review the risk/benefit balance and consider tapering or discontinuing the medication, as suggested by the American Family Physician 1, 2
