Best Anxiety Medication for a 74-Year-Old Female with Dementia

Selective serotonin reuptake inhibitors (SSRIs) are the first-line pharmacological treatment for anxiety in elderly patients with dementia, with non-pharmacological interventions like cognitive behavioral therapy being preferred initial approaches when possible. 1

Non-Pharmacological Approaches (First-Line)

Before initiating medication, consider these evidence-based non-pharmacological interventions:

1. Cognitive Behavioral Therapy (CBT)

   • Probably reduces depressive symptoms and anxiety in dementia patients 2
   • Improves quality of life and activities of daily living 2
   • Can be adapted for patients with mild to moderate cognitive impairment

2. Music Therapy

   • Most effective non-pharmacological intervention for anxiety in dementia 3
   • Also reduces caregiver burden

3. Physical Exercise

   • Second most effective non-pharmacological intervention 3
   • 50-60 minutes daily, distributed throughout the day to prevent fatigue 1

4. Environmental Modifications

   • Decrease sensory stimulation
   • Create a calming physical environment 4

Pharmacological Treatment Algorithm

When non-pharmacological approaches are insufficient:

First-Line: SSRIs

• Preferred options: Sertraline, vortioxetine, or mirtazapine 1
• Dosing: Start low, go slow
• Rationale: SSRIs significantly reduce overall neuropsychiatric symptoms and agitation in individuals with dementia 1
• Avoid: Fluoxetine (long half-life and side effects in elderly) 1

Second-Line (for acute anxiety only, short-term use):

• Lorazepam
  • Dosing: 0.25-0.5 mg orally
  • Maximum: 2 mg in 24 hours for elderly patients 4
  • CAUTION: Benzodiazepines are associated with cognitive impairment, falls, fractures, and addiction in elderly 1

Medications to AVOID:

1. Benzodiazepines (except for very short-term, acute use)

   • Associated with cognitive impairment, reduced mobility, falls, fractures 1
   • Beers Criteria recommends avoiding in elderly, especially with dementia 1

2. Antipsychotics

   • FDA black box warning for increased mortality in dementia patients 1
   • Associated with falls, stroke, and death 1

3. Tricyclic antidepressants

   • Anticholinergic burden particularly harmful in dementia 1

Monitoring and Assessment

• Use validated anxiety assessment tools:

  • Penn State Worry Questionnaire-Abbreviated (PSWQ-A) - Cut-off of 17 suggests significant anxiety 1
  • Geriatric Anxiety Inventory (GAI) - Cut-off score of 8 for mild/moderate dementia 1

• Monitor for:

  • Medication side effects
  • Changes in cognitive function
  • Falls risk
  • QT prolongation (with some medications)
  • Therapeutic response

Implementation Tips

1. Start with a 4-6 week trial of non-pharmacological interventions before considering medication
2. If medication is needed, start with lowest possible dose of an SSRI
3. Regular reassessment every 2-4 weeks initially
4. Avoid polypharmacy - consider deprescribing other medications that may worsen anxiety or cognition
5. Involve caregivers in both non-pharmacological interventions and medication management

Common Pitfalls to Avoid

• Using benzodiazepines as first-line treatment - these can worsen cognition and increase fall risk
• Overlooking depression - anxiety and depression often co-occur in dementia
• Failing to rule out medical causes of anxiety (pain, constipation, urinary retention)
• Continuing medications indefinitely without reassessment
• Using antipsychotics for anxiety symptoms without clear indication

By following this approach, you can effectively manage anxiety in your elderly patient with dementia while minimizing risks associated with pharmacological interventions.
