What is the best treatment approach for anxiety from being left alone in older adults?

Treatment of Anxiety from Being Left Alone in Older Adults

Cognitive Behavioral Therapy (CBT) delivered individually is the first-line treatment for anxiety in older adults, including anxiety from being left alone, with SSRIs (specifically sertraline or escitalopram) as the preferred pharmacologic option when psychotherapy is unavailable or insufficient. 1

Initial Assessment and Non-Pharmacological Approaches

Before initiating any treatment, rule out underlying medical causes of anxiety symptoms, assess for medication side effects contributing to anxiety, and address sensory impairments that may exacerbate symptoms. 2 Explore the patient's specific concerns about being alone, ensure effective communication and orientation, and treat any reversible causes of anxiety. 1

Cognitive Behavioral Therapy (First-Line)

CBT is the psychotherapy with the highest level of evidence for anxiety disorders in older adults and should be prioritized when available. 1, 2

• Individual face-to-face CBT is superior to group therapy in terms of clinical and health-related economic effectiveness. 3
• CBT can be delivered in the patient's own home, which is particularly relevant for older adults with anxiety about being left alone. 4
• Remote CBT (via telehealth) is highly effective for older adults, with a significant effect size of -0.63 for reducing anxiety symptoms compared to non-CBT controls. 5
• If the patient does not want face-to-face CBT, self-help with professional support based on CBT is a viable alternative. 3, 1

Treatment duration and monitoring:

• CBT typically requires 12-20 sessions for meaningful improvement, though briefer interventions (6 or fewer sessions of 15-30 minutes) adapted for primary care settings can be effective. 6
• Assess treatment response at 4 and 8 weeks using standardized validated instruments. 1
• Treatment gains are maintained at follow-up in 77.8% of effective interventions. 3, 6

Additional Non-Pharmacological Interventions

For older adults who cannot access CBT or as adjunctive treatments:

• Motivational interviewing combined with psychoeducation and breathing techniques has demonstrated significant anxiety reduction at 3-month follow-up in patients aged 60 and older. 2
• Music therapy, massage, mindfulness, yoga, and pleasant activities have shown potential for alleviating anxiety in older adults. 7, 8

Pharmacological Treatment

When psychotherapy is unavailable, declined by the patient, or insufficient after 8 weeks despite good adherence, initiate pharmacotherapy. 1

Preferred First-Line Medications

Sertraline and escitalopram are the preferred SSRIs for older adults due to favorable safety profiles and low potential for drug interactions. 1

Dosing strategy for older adults:

• Start low and go slow: Begin sertraline at 25 mg daily (half the standard adult starting dose). 1
• Escitalopram has the least effect on CYP450 isoenzymes, resulting in lower propensity for drug interactions—critical in elderly patients often taking multiple medications. 1
• Increase doses at 1-2 week intervals for sertraline, monitoring for tolerability. 1

Alternative first-line option:

• SNRIs (venlafaxine or duloxetine) are appropriate alternatives if SSRIs are ineffective or not tolerated. 1

Medications to Avoid

Paroxetine and fluoxetine should generally be avoided in older adults. 1

• Paroxetine has significant anticholinergic properties and increased risk of suicidal thinking. 1
• Fluoxetine has a very long half-life and extensive CYP2D6 interactions, making it problematic in elderly patients. 1

Benzodiazepines (e.g., lorazepam) require extreme caution:

• If necessary, reduce lorazepam dose to 0.25-0.5 mg in elderly patients, with a maximum of 2 mg in 24 hours. 1
• Use lower doses with shorter half-lives. 1

Monitoring and Treatment Duration

• Initial adverse effects of SSRIs can include anxiety or agitation, which typically resolve within 1-2 weeks. 1
• Review all current medications for potential interactions, particularly with CYP450 substrates. 1
• Monitor for QT prolongation if using citalopram (avoid doses >20 mg daily in patients >60 years old). 1
• For a first episode of anxiety, continue treatment for at least 4-12 months after symptom remission. 1
• For recurrent anxiety, longer-term or indefinite treatment may be beneficial. 1

Treatment Adjustment

If symptoms are stable or worsening after 8 weeks despite good adherence:

• Switch to a different SSRI or SNRI. 1
• Add a psychological intervention to pharmacotherapy. 1
• Consider combination therapy (CBT plus medication) for severe cases. 6

Common Pitfalls to Avoid

• Do not discontinue SSRIs abruptly—taper gradually to avoid discontinuation syndrome (dizziness, paresthesias, anxiety, irritability). 1
• Failing to identify and treat underlying medical causes of anxiety before initiating treatment. 2
• Using high doses of medications without appropriate dose adjustments for elderly patients. 2
• Relying solely on medication without addressing underlying cognitive and behavioral patterns related to being alone. 6
• Neglecting to assess treatment response systematically using standardized anxiety rating scales. 1, 6
