Best Interventions to Decrease Confusion in Elderly Patients with Sundowning Syndrome

Environmental modifications, particularly optimizing lighting and establishing predictable routines, are the most effective first-line interventions for decreasing confusion in elderly patients with sundowning syndrome. 1

Understanding Sundowning Syndrome

Sundowning syndrome is characterized by the emergence or worsening of neuropsychiatric symptoms such as agitation, confusion, anxiety, and aggressiveness in late afternoon, evening, or at night in elderly patients, particularly those with dementia 2. This phenomenon is highly prevalent among individuals with cognitive impairment and can significantly impact quality of life for both patients and caregivers.

Environmental Interventions (First-Line)

Lighting Optimization

• Provide appropriate lighting with exposure to natural light during daytime hours 1
• Use soft, non-glaring light in the evening that reduces shadows 1
• Implement light-colored walls with matte sheen and light flooring with low-glare finish 1
• Consider light therapy (2500-5000 lux, 1-2 hours duration, between 9:00-11:00 AM) for patients with dementia 1

Orientation Enhancement

• Ensure clocks and calendars are easily visible to help with temporal orientation 1
• Provide clear signage and visual cues in the environment 1
• Use color-coded or graphic labels on closets, drawers, and other items 1
• Reduce glare from windows and mirrors that can cause disorientation 1

Noise Management

• Create an enhanced acoustical environment using sound-absorbing materials (carpets, curtains, ceiling tiles) 1
• Reduce loud noise sources (overhead paging, machines) 1
• Consider providing calming music, which has been shown to decrease anxiety 1
• Use portable hearing assist devices for patients with hearing impairment 1

Behavioral and Routine Interventions

Establish Consistent Routines

• Implement punctual and routine schedules for activities, exercise, meals, and bedtime 1
• Avoid moving patients between rooms or wards unless absolutely necessary 1
• Ensure care is provided by familiar healthcare professionals 1

Communication Strategies

• Use the "three R's" approach: repeat, reassure, and redirect 1
• Explain all procedures and activities in simple language before performing them 1
• Reorient the patient by explaining where they are and who you are 1
• Avoid using negative language (words like "crisis," "pandemic," "lockdown") 1

Activity Management

• Introduce cognitively stimulating activities, such as reminiscence therapy 1
• Simplify tasks by breaking complex activities into manageable steps 1
• Reduce exposure to overstimulating environments 1
• Facilitate regular visits from family and friends when possible 1

Pharmacological Interventions (Second-Line)

Pharmacological interventions should be considered only when non-pharmacological strategies fail to reduce behavioral symptoms sufficiently:

• Cholinesterase inhibitors may improve behavioral symptoms in patients with dementia 1
• Melatonin may help regulate sleep-wake cycles and reduce sundowning behaviors 3
• Selective serotonin reuptake inhibitors (SSRIs) like citalopram and sertraline are preferred for treating depression in patients with dementia 1
• Avoid medications with strong anticholinergic effects (diphenhydramine, cyclobenzaprine, oxybutynin) as they can worsen confusion 1

Common Pitfalls to Avoid

• Failing to rule out reversible causes of increased confusion (e.g., vitamin B12 deficiency, medication side effects) 4
• Using physical restraints or sedatives as first-line management 1
• Neglecting caregiver education on strategies to manage confusion 1, 4
• Overlooking the impact of polypharmacy on cognitive function 1
• Attributing all behavioral changes to dementia without investigating other potential causes 4

Implementation Algorithm

1. Assess for reversible causes of confusion (medication side effects, infections, metabolic disturbances)
2. Optimize the environment (lighting, noise, orientation cues)
3. Establish consistent routines and familiar caregivers
4. Implement behavioral strategies (redirection, simplification, stimulating activities)
5. Consider pharmacological interventions only if non-pharmacological approaches are insufficient

By systematically addressing environmental factors and establishing consistent routines while minimizing pharmacological interventions, confusion in elderly patients with sundowning syndrome can be significantly reduced, improving quality of life and reducing caregiver burden.
